What you should know about LASIK

Many people have had their vision permanently improved through LASIK, or laser eye surgery. This can be a wonderful option for those who don't like dealing with glasses or contact lenses. Anyone who is contemplating having LASIK performed on their eyes, however, must keep a few things in mind.
Most people will at some point still have to wear reading glasses for near vision. LASIK corrects your distance vision and not near vision. This is true even if you can currently remove your glasses to read at near, as this will not be possible after having LASIK. One option for getting around this is monovision, or leaving one eye near-sighted to keep the ability to read at near. This can affect depth perception due to the fact that the eyes won't work together as a team as well because you will always have one clear eye and one blurry eye.
Commonly after LASIK, patients will complain of nighttime glare and dryness. These symptoms usually improve or resolve after approximately six months, but can however last longer or be permanent.
One of the main things to remember is that there is no guarantee that you will be perfect 20/20 after the surgery. Because everyone heals differently, many people are left with a slight prescription afterwards. If the residual prescription is too great, an enhancement surgery can be performed. However, many people will have a very thin pair of glasses to wear occasionally to see their very best.

Do you ever have blood in the whites of your eyes?

Often patients will come into the optometrist's office in a panic because they awoke with the white of their eye completely bloody. While looking very serious, this is actually no more serious than a bruise. This is called a subconjunctival hemorrhage, and is due to a broken blood vessel lying between the white of the eye and the clear conjunctiva that lies over top of it. These blood vessels can often break due to getting bumped in the eye, or more commonly from anything that temporarily spikes your blood pressure. These are commonly seen in people who have coughing fits, a history of vomiting, or any kind of straining, whether it be due to heavy lifting, pushing during child birth, or straining using the bathroom.The bloody appearance usually has very few other symptoms. There is typically no pain, discharge, or change in vision. The blood will be reabsorbed by the body in approximately a week. Because other more serious conditions can cause redness in the eye, it is always best to see your eye doctor with any new onset of redness.

Sleeping with Contact Lenses

Many people want a contact lens in which they can sleep overnight for multiple nights. There are even some contact lenses that are FDA approved for 30 days of continuous wear. These contact lenses gained this FDA approval because they are very permeable to oxygen and let the cornea "breathe". However, sleeping in contact lenses, whether it be traditional contact lenses or the newer breathable ones, still greatly increases the risk of eye infections. These eye infections, besides being uncomfortable, can be potentially vision threatening. They can lead to corneal ulcers, which have the potential to permanently scar the cornea. This can lead to permanent decrease in visual acuity or blindness. To greatly minimize this risk, it is recommended that all contact lenses be removed and disinfected nightly. As always, at the first sign of any redness, pain, or change in vision, it is advised that your contact lenses should be removed immediately and you should contact your eye doctor.

Becoming an Eye Donor

More than 40,000 U.S.residents were in need of a corneal transplant just last year.  With a 95% success rate a corneal transplant can restore a patient’s sight and greatly improve their quality of life.  Any one can be a donor regardless of age, blood type, or refractive error.  Corneal tissue must be donated within 12 hours after death and be transplanted within seven days.  The Central Ohio Lions Eye Bank facilitates the retrieval of donated tissue and the transplantation to the recipient.  They are also involved in educating physicians and furthering eye research.  To become an organ donor simple go to www.bmv.ohio.gov and click on the donate life tab.  From there you can specify to be a donor of all organs, tissues, and eyes or you click individually on which areas you which to donate and for what purpose they may be used.  The need is great and donations are limited so please considering giving someone the gift of sight.

Diabetic retinopathy is on the rise!

Data was published recently stating that Diabetic retinopathy had increased in incidence 89% from 2000 to 2010.   Diabetes affects 8.3 percent of the U.S. population according to the National Diabetes Information Clearinghouse.   In addition, approximately 1.9 million people over the age of 20 were newly diagnosed with the disease in the U.S. in 2010.  It is the leading cause of new cases of blindness in adults in the U.S. and the seventh leading cause of death in the U.S.  With these staggering statistics it is imperative that all individuals diagnosed with Diabetes or pre-Diabetes continue with annual eye exams to monitor the health of their eyes.

Top Ten Reasons NOT to Wear Prescription Sunglasses



The Doctors and Staff of Rinkov Eyecare Centers firmly believe that sunglasses are necessary for nearly every patient we see. The sun's rays are extremely harsh on the eyes and can lead to terrible vision and health related-issues down the road. Plus sunglasses are cool and look good!

Even though we feel very strongly about sunwear, we often hear objections from our patients. Some are, on the surface, valid. Whereas some are a bit humorous. Below are the top 10 reasons we hear from patients why they should not get sunglasses, followed by our reasoning why every patient is better off making an investment in quality sunwear. Almost without exception, our patients are thrilled with their prescription sunglasses and are actually aggravated they waited so long!  Our hope is that you won't wait too much longer either.

1.  Sunglasses are too expensive! 

Did you know that sunglasses reduce or delay a number of eye diseases? It is true! Cataracts, macular degeneration, corneal disease, and lid lesions are all reduced greatly or delayed by simply wearing a quality pair of sunglasses. A pair of good sunglasses are MUCH less expensive than medical intervention to save your sight!

2.  I'm not light sensitive.

Patients will tell us that the bright sun does not bother them… BUT, it does bother your retinas!  Everyone's retinas are incredibly sensitive to light. If you are diabetic, hypertensive, have lighter eyes and/or are taking any number of medications, this also increases the sensitivity of your retinas. Ask any Dermatologist whether UV rays are harmful for your skin and they will tell you that over a lifetime, UV exposure greatly increases your risk for denatured skin and cancers. Your eyes are no different and can be easily protected with quality sunglasses. And unlike putting zinc on your nose, you will look good too!

3.  I'm never outside :)

Really? I mean… really? You never walk outside? Never drive in a car? Never?  Try a pair of quality prescription sunglasses while driving and you will be amazed at what you have been missing!

4. I wear Transitions or other self-tinting lenses.

Transitions are a great product. Our patients love them. But ask any transitions wearer if they prefer Transitions over a pair of sunglasses and nearly all of them prefer the sunglasses. Transitions and other self-tinting lenses cannot match the performance that a quality pair of sunglasses provides. Sunglasses provide superior UV protection, are darker, come in a variety of tints, are polarized and typically have a larger frame (which provides protection to the sensitive skin around your eyes).

We think of Transitions and other self-tinting lenses as a convenient comfort filter for on the run occasions. They are better than nothing, but are not a substitute for sunglasses.

5. I wear a clip or a shield over my glasses.

As doctors and vision professionals, we want you to have the best vision possible. Looking through multiple surfaces simply is not as good as looking through one. In fact, light through multiple optical surfaces is degraded, causing your vision to suffer. And let’s face it, a good looking pair of sunglasses looks so much better than one of those bulky shields or a imperfect clip that is all bent out of shape!

6. I'll lose them!

Generally, people do not lose what we value. And trust us, once you put on a pair of quality prescription sunglasses, you will value them!

7. My insurance won't cover prescription sunglasses.

Actually, most vision plans have benefits for prescription sunglasses. If not, we always offer a discount on a second pair!

8. They give me headaches.

Our Eye Doctors have found that most of the time the sunglasses are not the real reason for your headaches. You should visit your eyecare provider to find the real root of your headache. It could be the poor optics from over-the-counter or cheap sunglasses. It could also be that you suffer from dry eyes or even cataracts. There is also the possibility that the prescription is wrong or the lenses are too different from your regular glasses. All these factors are taken into account with our patients, which is why they love their prescription sunglasses so much!

9. They'll make my eyes dependent.

There is no physiological dependence developed. You will, however, enjoy the benefits of clear vision, less glare, no squinting, and eye protection. Plus, you will look great!

10. I wear contacts

Ok, so you do not require prescription sunglasses over your contact lenses. However, if you are like the majority of our patients, you are seeking the best visual performance out of you contact lenses. If that is the case, then what is the logic in putting a cheap pair of drugstore sunglasses on top of your perfectly fitted contact lenses? Plus the optics on these cheap sunglasses are terrible!  Trust us… there is a HUGE noticeable visual difference with a quality pair of ophthalmic sunglasses compared to a sunglasses picked off the rack at a drugstore or in line at the checkout counter elsewhere.

We hope that this article has persuaded you non-believers to give prescription sunglasses a try. We know you will love them. If you would like to learn more, feel free to call one of our offices or check out our website (www.rinkoveyecare.com).

Just because summer is over, doesn't mean you don't need sunglasses!



Now that summer is over many people feel sunglasses are not as important  However, sunglasses are just as important, if not more, in the winter. Sunglasses not only provide shading to the eyes for visual comfort, but they more importantly act as sunscreen for the eyes blocking out harmful UV radiation. This UV radiation can increase the risk of macular degeneration, cataracts, pinguecula (yellow bumps on the white of the eye), and perhaps most dangerously malignant melanomas of the eyelid. While the sun may not be as bright in the winter, we are exposed to high levels of UV radiation because it reflects off the snow on the ground. Therefore wearing hats that block the sun are ineffective because the UV light is hitting our faces from a different direction.

Blinking



 

Normally the act of blinking is both a voluntary or involuntary action. This blinking process has several functions  including the spreading of tears over the surface of the eye, protecting the eye in infants and is decreased in certain diseases as Parkinson nd limiting the amount of light entering the eye. This type of involuntary blinking is absent disease. Normally we blink once every 5 seconds or approximately 13,000 blinks during the course of a day. Bright lights or a sudden loud noise may also cause us to blink.

What is a cataract?

Many people have heard the term cataract before, but are unsure as to what exactly it is. A cataract is a clouding of the natural crystalline lens of the eye. This lens sits right behind the iris, the colored part of the eye. It is used to help focus when reading at near. Due to ageing, ultra-violet light exposure, injury, or certain medications, it can start to yellow and become opaque. This clouded lens, or cataract, can cause a glasses prescription change, glare, blur, and washing out of colors. Once the visual symptoms become bothersome enough, your optometrist will refer you to an eye surgeon to have it removed. An artificial lens is then inserted into the eye to help maintain the optical power of the eye.
One of the best ways to slow down the progression of cataracts or delay their onset is to protect your eyes from UV light. This can be achieved by wearing sunglasses when outdoors. This is important year round, not just in the summer months. Your optometrist will monitor for any cataract changes at your yearly eye exam.

When a stye doesn't cooperate?

 

Many of us are a familiar with the stye, also called internal or external hordeolum. All of moms remedies that use heat apply, right? Hot washcloth compresses, hot tea bag, microwaved potato in a paper towel? Can you then eat this potato? I'll take mine loaded, thank you.

I recently had a stye resistant to compresses, and then resistant to topical and oral antibiotics. Two weeks later I was left with a pebble like bump in the lid called chalazion. Unsightly and at risk for repeated difficulties, I opted for excision; surgeon speak for cut and drain. All better now, but I'm not anxious to hear scalpel , "slight" burn, or cautery any time soon.

Bottom line. If your stye doesn't show nice progress within 24 hours by your favorite home remedy, visit your eye care practitioner early on to help avoid excision.

Changing Eye Color

I have seen a number of patients over the past few weeks who have noticed their dark brown eyes turning a whitish blue color. This is known as Arcus Senilis. The change in color is due to a build of lipids and cholesterol in the corneas stroma. The deposits usually form in a ring like shape around the outer edge of the cornea which lies on top of the iris, or colored part of the eye. This whitish blue ring covers the iris’s natural color. The appearance of this ring can be an indication of hypercholesterolemia if occurring at a young age but can also be seen in some patients over 60 who have normal lipid levels. If you begin to notices changes in the appearance of your eye color it is best to follow up with your optometrist for a full evaulation.

Medications with Glaucoma

Have you ever seen as a warning on any of your medications that they should not be taken if you have glaucoma? The reason for this is that these medications can cause a slight dilation of the eyes. Glaucoma is a condition in which the pressure of the fluid in the eye is too high. This fluid, known as aqueous, is produced behind the iris, flows forward through the pupil and drains out in the angle formed by the back of the cornea and the front of the iris. When the pupil dilates, this drainage angle narrows, thus impeding some of the outflow of the aqueous. This can cause the aqueous to backup and therefore fluid pressure in the eye to elevate. This can be especially dangerous in someone who has a form of glaucoma in which the angle is already narrow or whose pressure is already elevated. When in doubt, it is best to consult your eye doctor before taking any of these medications with such warnings.

Carrots are not the only food your eyes need

Many people have heard that they need to eat carrots for their eye health. They also should be eating green leafy vegetables such as spinach and kale. These are rich in lutein. Another important nutrient is zeaxanthin, which can be found in paprika and orange peppers. Lutein and zeaxanthin are antioxidants important in the health of the macula. The macula is the part of the retina affected in macular degeneration. If these food are not part



of your normal diet, these nutrients can be found in supplement form from your eye doctor. Rinkov Eyecare Center offers the only supplement on the market that contains the exact ration of zeaxanthin and lutein that is found naturally in the eye. Give us a call to find out more.

Back to School Eye Exams - Don't forget sunglasses!

With back to school time fast approaching, many kids will be getting their back to school eye exams. It is important to remember that kids need to protect their eyes from the sun and harmful UV rays as well as adults. Many parents choose to get their children's glasses with photochromic lenses. These lenses change to sunglasses when outdoors. Many kids find these very helpful on the playground, as they give sun protection without having to have two pairs of glasses at school.

The Solution may be the Culprit

.A common complaint among contact lens wearers is dryness, especially toward the end of the day. While contact lenses can make pre-existing dry eye worse, the disinfecting solution being used can be a culprit too. Many of the store brand solutions are generics of the older versions of name brands. These older technology solutions tend not to disinfect as well and cause more eye irritation due to the preservatives in them. The name brand solutions are constantly improving their disinfecting ability and improving upon comfort of the preservatives in them. Some name brand solutions, once neutralized, are totally preservative free. It is best not to change cleaning solutions without first consulting your eye doctor.

Are you still cleaning your lenses?

Are you still cleaning your lenses? Favorable testimonies continue to mount from patients having switched to daily disposable contacts. It is routine for them to say that dryness is diminished, that allergies don’t bother them, and they can’t feel the lenses in their eyes. They also report stable clearer vision, that is, less “filmy” times. Clinically, these lenses are helpful in cases of dry eye syndrome, contact lens acute red eye, and contact lens papillary conjunctivitis. Product choices have expanded, including lenses to address astigmatism and UV protection. Visit your eye care professional to inquire.

What to do with a floaters?!??!

Many people report to the optometrist's office stating that they are seeing floaters. These are often described at black or gray, semi-transparent spots that drift through the vision. While often times these floaters are completely harmless, they can be a sign of a more dangerous problem. Patients should report to their optometrist's office with any new onset of floaters, especially if there are large numbers of them or look like cobwebs in their vision. Floaters accompanied by flashes of light, often described as camera flashes, shooting stars, or pinpoints of light, can also be the sign of a problem. Floaters with the appearance of a curtain over the vision is also the sign of a bigger problem. If a patient sees any of these things, they should report to their eye doctor's office immediately.. They should not wait to see if they will go away on their own as time is often critical in repairing any problems that are causing these symptoms.

Multifocal Contact Lenses

For contact lens wearers over the age of forty, an excellent option for vision correction is multifocal contact lenses. One has to go into a multifocal fitting with the right expectations, however. Unlike a glasses multifocal which has distinct areas for distance and near, a multifocal contact lens blends distance and near simultaneously.This results in very good vision, however it will not be as good as distance only contact lenses or glasses. Many people will get some glare and haloes with nighttime driving. Also a pair of readers may be necessary for very small print, especially in low lighting.

Polycarbonate and Trivex Lenses

For many years, most patients have been using glasses lenses made of a material called polycarbonate. The advantage of polycarbonate is that it is thinner, lighter, and most importantly, more impact resistant than regular plastic lenses. The disadvantage of polycarbonate is that the optics of the material are not quite as good.This is especially true in prescriptions that require a lot of astigmatism correction. There is now a newer material available at your optometrist's office called Trivex. It has all the advantages of polycarbonate, including equal impact resistance, however the optics are much superior to polycarbonate. When Trivex is combined with an anti-reflective coating, patients will notice they have much better vision.

FAQ: LASIK

Many people come into the eye doctor's office with questions regarding laser eye surgery. LASIK surgery is a good alternative to glasses and contact lenses, however, it does have some potential negatives. Afterward, many people suffer from glare and haloes, especially at night. New or worsening dry eye can be a side effect as well. These often dissipate after six months, but not always.There is no guarantee that your end result will be perfect 20/20 vision. While 20/20 vision is the goal, everybody heals differently and a mild prescription may still be needed to see your very best. Also, after the age of forty, everyone starts to need reading glasses or a bifocal for near tasks. This will still be true even after LASIK, so you won't be out of glasses completely forever. As long as LASIK surgery is approached with the right expectations, it can be a very rewarding method of vision correction.

Do you have trouble reading with or without glasses?

Many patients report to their optometrist's office reporting that they are having trouble seeing to read. This is a natural aging change called presbyopia. The crystalline lens within the eye that changes shape to focus at near starts to stiffen around age forty. As this happens, the patients will find they have to push their reading material farther and farther away from them. This process continues slowly from approximately age 40 to age 55. During this time patients will usually get their first bifocal or reading glasses,and find they have to be strengthened every few years as it progresses.

Nutrition and Your Eyes

Nutrition is a growing topic of discussion in optometric practice today. There is increasing evidence of it's impact on eye health. Many studies have shown vitamins C, D, E, Zinc and Omega-3 fatty acids to be protective against macular degeneration and possibly cataract formation as we age.  The newest research is centered around macular pigment density.  Studies have shown that macular pigment density decreases as we age, in smokers and in individuals with a family history of macular degeneration.  Studies have also shown a correlation between macular pigment density and the development and progression of macular degeneration. Macular pigment is composed of the dietary carotinoids Lutein and Zeaxanthin.  Studies have shown that a higher dietary intake of Lutein and Zeaxanthin was independently associated with a decreased risk of progression to wet macular degeneration.  For those at risk for macular degeneration, a supplement containing the appropriate levels of Lutein, Zeaxanthin, Vitamins C, D, E, Zinc and Omega-3 fatty acids may help preserve vision.

Eye Drops are Meant to Drop in Your Eyes

Many people have trouble putting eye drops in their eyes when their optometrist prescribes them for them. Besides the obvious of dropping it right in the eye, there are a few tricks to getting eye drops in the eyes. One is to pull down on the lower lid while looking up slightly. The lower lid forms a little pouch, which the drops can be dropped into. The lower lid would be released and a few blinks would distribute the drop across the eye. Another trick is to tip the head back so that the eyes are pointed at the ceiling. With the eyes closed, the drop can be placed in the corner of the eye nearest the nose. Opening the eyes and tilting the head toward the ear on the same side will allow the eye drop to run into the eye. This would then be repeated for the other eye.

Ocular Migraines

A common complaint in the optometrist's office is seeing strange temporary distortions of vision. One common cause in ocular migraine. These visual distortions are known as auras and can present as zigzag lines, shimmering spots, kaleidoscope-like images, heat waves, or tunnel vision. They usually last about 10 to 30 minutes. Once they resolve, the patient may or may not be left with a headache.They are often caused by some common triggers, such as stress, lack of sleep, caffeine, MSG, sulfites in wines and cheeses, oral contraceptives, and some antibiotics. The best treatment is to avoid the trigger once it is identified.
Because other more serious and dangerous conditions of the eye can have strange distorting affects to the vision, if you are experiencing any new changes to your vision, you should be checked by your optometrist before assuming it is an ocular migraine.

When in doubt, use potato chips as glasses...

So the other evening I was watching a ball game and enjoying a sandwich and chips. The scores were scrolling across the bottom of ESPN's broadcast. I couldn't read most of them, and of course my glasses were not handy; after all, I am an optometrist. Funny thing I noticed; baked lays chips have tiny holes in them- don't ask me how I figured that out. Anyway, I held the chip close to my eye , looked thru one of those pinholes, and was able to read the scores. You never know where inspiration will strike. Bottom line- pupil size is relevant to optics. When we read better in good lighting, or squint, we are effectively reducing our pupil size- like pinholing. Pupil size is considered in multifocal contacts and LASIK as well. For the record, I have not examined doritos , pretzels or any other snack foods.

What you got there is a Corneal Guttata!

Corneal guttata are the most common primary corneal endotheliopathy and are present in 70% of the population over 40.  They are secretions of collagen from the endothelial cells that form a nodule on the back surface of the cornea.  The secretions occur when cells under stress secrete an abnormal membrane material.  When they are small and low in number a patient is assymptomatic, but as they become numerous and larger in size they disrupt the normal corneal function and result in decreased vision.  As the guttata coalese and the cornea becomes swollen, the condition is known a Fuch's Endothelial Dystrophy.  As Fuch's progresses it may lead to persistent corneal edema.  In early stages edema may be managed with medications but as it progresses a corneal transplant may be necessary.  Tools such as a specular microscope allow us to monitor and treat patients more effectively and in a timely manner.  A specular microscope screening may be present as part of comprehensive eye exam in certain offices.  This is another reason to maintain yearly eye exams, even in the absence of visual complaints

Eyes in the Sun

Exposure to the sun may be damaging to the eyes just as it is to the skin.  The sun emits UV-A and UV-B radiation that is absorbed by the tissues in the front and back of the eye.  This can result in an increased risk of cancers in all the different areas of the eye.  It may also increase the risk of certain types of cataracts and macular degeneration.  Although cataracts may be improved with surgery, macular degeneration is a leading cause of blindness as we age.  It is very important to wear good sun protection that covers the eyes well and has adequate UV-A and UV-B protection.  Also most of us remember to wear our sunglasses in the summer, but it is just as important to wear them in the winter when UV radiation may be just as intense.  Finally, remember to continue annual eye exams with your eye doctor to diagnose and monitor any problems that may result.

Eye Drops that Whiten Your Eyes

Many people who come into our office tell us that they use eye drops to whiten their eyes. These "gets the red out " medications should only be used on an occasional basis. They have drugs in them called vasoconstrictors that shrink the blood vessels in the white of the eye. With repeated use, the blood vessels become used to the drug, and  the eyes are always red unless you use the drop. This vicious cycle should be broken by switching to a drop that is simple an artificial tear and does not contain eye whitening medications. If the redness is accompanied by itching, a prescription antihistamine eye drop for allergic conjunctivitis can be used.

What to do with Metal in the Eye?

Unfortunately, something that is seen in the optometrist's office not infrequently is metallic foreign bodies in the front of the eye. The small pieces of metal become embedded in the cornea due to grinding or cutting metal while not wearing safety glasses. These metal pieces are removable from the eye with a rotating burr while the eye is numbed. However, besides being unpleasant to have and to have removed, these foreign bodies leave scars in the cornea, the severity of which depends upon how deep they are embedded.These scars will at best cause glare and at worst cause permanent decreased visual acuity or blindness. This can all be avoided by simply wearing safety glasses to protect the eyes from flying debris. Safety glasses can even be made by your eye doctor with your eyeglass prescription in them.

Ocular Anesthetics

Ocular local anesthetics are common pharmaceutical substances the optometrist may utilize during the course of a vision examination. These agents as in tetracaine or proparacaine, are derived and modified from the common drug cocaine. The cornea and the conjunctiva are readily anesthetized or numbed by these drops. The anesthetics are used in certain types of glaucoma testing, including tonometry for eye pressure determination and in pachyometry for measuring the corneal thickness. More commonly these drugs are used in diagnosing eye conditions as corneal abrasions and also in both diagnosing and removal of foreign bodies in the cornea and conjunctiva. Anesthetics, however can not be prescribed alone to relieve pain and discomfort since they actually slow down and prolong the healing process.

Will eating carrots really improve my vision?

Carrots contain a high level of beta carotene which the body converts to Vitamin A.  Our eyes depend on certain amounts of Vitamin A to maintain the health of the eyes surface as well as the proper function of the eyes retina.  Excessive amounts of Vitamin A will not increase the eyes function but too little Vitamin A can be detrimental to our vision.  Vitamin A deficiency is the leading cause of blindness in third world countries where malnutrition often leads to dehydrated corneas and retinal eye disease.  Proper diet can have a significant impact on our vision.  Eating a health balance of fruits, vegetables, fish, and nuts will provide the nutrients needed for our eyes to work to their best ability.

Why is it important to monitor the corneal endothelial cells?

Many people have asked me recently why it is important to monitor the corneal endothelial cells with a specular microscope, so I thought it would be a good topic to address.  The corneal endothelial cells have many important functions.  The most important are that they form a tight barrier to keep fluid from crossing from the aqueous (fluid in the front chamber of the eye) into the cornea and they pump excess fluid from the cornea.  This is important in allowing someone to see clearly because excess fluid can cause hazy or fluctuating vision.  Endothelial cells do not regenerate and due to the normal aging process the central cornea can lose 100 to 500 cells per year.   This number may be increased due to disease processes, contact lens overwear, surgery or trauma.   As these cells die they fall off into the anterior chamber of the eye and the remaining cells must change to accommodate the gap.  They do this by stretching or sliding into the empty position to fill the missing gap.  As they do this they change shape which is normal to a certain level, but when pushed to extremes can result in a breakdown of the cornea's normal functions.   The specular microscope allows us to assess the health of the cells with pictures and also a numerical analysis so we may make appropriate changes to protect someone's cornea.

What is astigmatism?

Many people are confused by the term "astigmatism" when they visit their optometrist. Many people think it is some sort of disease of the eye. It is actually a refractive condition of the eye like near-sightedness or far-sightedness. Astigmatism causes visual distortion due to the curvature of the front of the eye, known as the cornea, or the crystalline lens within the eye. The visual distortion results from the fact that the cornea or lens are not perfectly spherical, like a baseball, but have two different curvatures, like a football. The curve of any lens is one of the main things to give it power, therefore, if the cornea or lens has two different curvatures, it has two different powers, and is bent to two different points within the eye, depending on the orientation of the light entering the eye. This causes distortion. This can be corrected by your optometrist with eyeglasses or contact lenses that have two different curvatures to perfectly counter-balance the curves in your cornea or lens.

Diabetes and Eye Exams

 

For the many people who suffer from diabetes, it is of utmost importance to have a yearly dilated eye exam. Diabetes is a disease that affects the blood vessels of the body, particularly the eyes and feet. Having a yearly dilated eye exam will allow your optometrist to directly view the blood vessels in your retina, checking for any bleeding or leaking. In severe cases of diabetic retinopathy, new blood vessels can start to grow into the retina. This is especially dangerous because these new blood vessels destroy healthy retinal tissue. If this occurs, retinal laser surgery or other treatments are necessary to stop them before blindness results. A yearly dilated exam with your optometrist will help to catch any problems earlier, when they are much easier to treat and less irreversible damage has occurred.

Watch for the Giant Papillary Conjunctivitis!!

Giant papillary conjunctivitis is a common condition in which large bumps form under an individuals eyelid.  It is an allergic response that is most common in soft contact lenses that have a longer planned replacement time frame.  The residual proteins on the lens incite the allergic reaction, which can lead to irritation and excess movement with contact lens wear.  The prevalence of GPC has decreased since disposable contact lenses have become popular.  In addition to prescribing medications and/or discontinuing contact lens wear an eye doctor may switch someone with mild to moderate GPC to daily disposable contact lenses as a viable option.

Summerlike Weather - Watch those Corneas!

With the summerlike weather we have been having, one need to be diligent in wearing their sunglasses. One particular reason for this is pterygium. This is a growth of tissue that starts covering over the cornea. It is seen
primarily in people who are exposed to high UV levels. If the tissue grows far enough across the cornea, it can block vision and cause blindness. The tissue can be removed surgically, but often scars afterward and can return.
The best treatment is prevention, by blocking UV rays with sunglasses.

Why do my eyelids twitch sometimes?

An involuntary eyelid twitch is most likely what we refer to as a Blepharospasm.  This is a neurological condition involving the contraction of the muscles around the eye.  It normally lasts only a few seconds and often affects just one eye.  The condition is usually brought on by increased stress to the body.  It may happen more often while someone is overly tired or stressed due to a situation in  here everyday life.  Unfortunately there is not a lot that can be done with medication or treatment to stop the twitching.  For most  people the best advised is to try to get more sleep and do whatever possible to reduce their daily stress.  Normally the condition will resolve on it's own within a few days time.  If the condition is persistent and severe enough to interfere with patient's daily activities, Botox injections have been used to temporally paralyze the muscle.

Bloody Red Eyes!

Many people come into their optometrist's office in a panic because they have a blood red eye. This is called a subconjunctival hemorrhage (SCH).

This is similar to a bruise elsewhere on the body, but because the conjunctiva overlying the blood is clear, it looks bloody. This condition is usually no more harmful than a bruise and will resolve uneventfully with time. They are caused by trauma to the eye, anything that affects blood clotting, such as use of blood thinners, and straining, such as with lifting, vomiting, pushing during childbirth, and straining using the restroom.

Diabetes and Eye Exams

It is very important for everyone to have a yearly dilated eye exam, especially if you are diabetic. Diabetes affects blood vessels throughout the body. Two of the most common parts of the body affected are the eyes and feet. Diabetes can cause bleeding and decreased oxygen supply to the retinal tissues. This can cause new blood vessels to grow into the retina, which damage the surrounding healthy tissue. If not found and treated, blindness can result. Yearly dilated eye exams can detect changes early when treatment is easier and often more successful.

Side Effects and Glaucoma

There are two groups of drugs that have side effects upon the eyes,especially in lowering the pressure within the eyes or the IOPS. The first group contains ethanol or alcohol and the second contains cannabinoids.

Ethanol can reduce the IOP's in both the normal individual but also in those patients diagnosed with glaucoma. This effect occurs one to two hours after consumption of an alcoholic drink.

The other drug group that can lower the eye pressure are the cannabinoids,which includes the marijuana plant. Smoking or ingesting marijuana will provide a marked reduction in eye pressures. This effect occurs about sixty to ninety minutes after smoking and will lower the pressures for about four hours.

The systemic side effects of both alcohol and marijuana consumption, however, make them obvious poor choices for the treatment of glaucoma. Your eye care professional will be able to discuss other alternative and safer methods to controlling your glaucoma.

What is Presbyopia?

Presbyopia is a condition in which the lens of the eye becomes hardened.  As this happens the eye slowly loses it's ability to focus objects from distance to near.   Individuals usually start to notice a difficulty focusing at forty and it usually worsens until the mid sixties when it stabilizes.  It will eventually affect everyone and can easily be monitored and treated with yearly eye exams.  Different treatment options may include glasses, contacts or different types of refractive surgery.

How long will LASIK vision correction last?

Lasik should ideally provide a permanent vision correction.  Once the cornea is modified it should never revert back to its original shape and should only change slightly as a person ages.  While the cornea should remain stable, there are other parts of our eyes that will continue to change as we age.  The most significant vision change people notice after Lasik is due to the lens changes that occur around the age of 40.  The lens of our eyes slowly stops being able to accommodate, or focus, as we age. This causes near vision to become blurred and brings on the need for reading glasses. This process happens to all of us whether we have had Lasik or not.  So  while a patient's distance vision should remain clear permanently, even post-Lasik patients will  eventually need glasses again for  reading and near work.  It is importance after any corrective vision surgery to continue to have yearly eye exams.  Your doctor will be able to monitor the health of your eyes and prescribe the proper reading correction when the time comes.

What do Preservatives have to do with my eyes?

Preservatives are a common chemical preparation used in most ocular medications and contact lens solutions. These chemicals prevent bacterial growth within the bottle once it has been opened , thus preventing the spread of possible infections. These preservatives, however, can occasionally irritate and damage the eyes outer surface. There are several groups of preservatives that are tolerated quite well by our eyes without any adverse reactions. One group , the mercurials which includes thimerosal, was once a main stay in early contact lens solutions. Many patients though the use of these thimerosal based products developed an allergic sensitivity and were forced to discontinue not only the contact lens solution but even the contact lens. Today thimerosal is not a common preservative in name brand contact lens products instead there is a broad selection of excellent solutions the patient can safely use. The doctors at Rinkov Eyecare Center always consider the patients allergy history in prescribing the proper products for the care of their eyes and contact lens.

Bloodshot Eye! Why?

A common condition seen in the eye doctor's office is a subconjunctival hemorrhage (SCH). This condition usually sends people into their eye doctor's office in a panic, but is actually not an emergency. Patients will often wake up with bleeding over the white of their eye. This is nothing more than a bruise in the eye. In a normal bruise, the skin on top of the blood causes it to have a purplish hue. In the eye, the blood is under the conjunctiva, a clear tissue that lines the white of the eye.  Since the tissue over top is transparent, the bruise looks bright red. This can be caused by trauma to the eye, exertion from heavy lifting,  straining using the restroom, pushing during labor, coughing, and vomiting. In rare cases, it can be due to a clotting problem with the blood. This is only suspected if it occurs repeatedly. For this reason it is more common in people who are on blood thinners or NSAIDs. The treatment for a SCH is time. As with any bruise it will fade with time as the body reabsorbs the blood from the broken blood vessel.

Pachymetry - Very Cool Stuff!

The optometrist will often have a patient return to the office for a special test called pachymety. This instrument using ultrasound technology will determine the central cornea thickness. This measurement is important in evaluating the intraocular pressure (IOP) for a patient who may be a glaucoma suspect. A thicker cornea results in an IOP reading for a patient that is higher than the actual pressure reading, whereas a thinner cornea will have an IOP reading lower than actual. A correction or adjustment is then applied to the IOP measurement to give the optometrist a more true reading. Pachymetry has other clinical uses involving the cornea. The thickness measurement is needed to determine if a patient is a suitable candidate for laser refractive correction or surgery. It also has a role in measuring corneal swelling from contact lens wear or from corneal disease.

Contact Lenses for BiFocals!

Many people feel that once they need a bifocal, they are unable to wear contact lenses. This is not true. In fact there are several options available. A person can wear two contact lenses for distance vision and then wear over-the-counter reading glasses over the contact lenses when reading. Another option is called monovision. In this method, a person wears a contact lenses that focuses them at distance in one eye and another contact lens that focuses them at near in the other eye. The brain learns to ignore the blurry eye not being used. The third option is multifocal contact lenses. At one point these were not very successful, however they are much better now and have a high success rate. These contact lenses let the patient view distance and near out of both eyes without any glasses.

Your Eyes on Steroids! (Hint: it won't make your eyes bulky)

Many of our patients have been placed on medications by their family doctor that have adverse reactions upon our eyes. One group of these medications, steroids, are often used in treating conditions as arthritis, some autoimmune diseases such as systemic lupus, and respiratory conditions as asthma. The two most common side effects are cataracts and increased intraocular pressure.

The ocular side effects of steroids are related to the method or route of administration. There is a strong association between inhaled steroids and a type of cataract called posterior subcapsular cataract or PSC. Patients on long-term rather than short term use of steroids such as prednisone, are at higher risk for this type of cataract formation. Increased intraocular pressures provides the patient with a risk factor for possible glaucoma development. Due to these two adverse effects of steroids, the patient should have a dilated and slit lamp examination of the eyes every 6 to 12 months. Both of these important tests are part of a comprehensive eye exam at any of our Rinkov Eyecare locations.

Morning Eye Irritation is Irritating!

Often patients will report waking in the morning with severe eye irritation, watering, blur, and light sensitivity. These symptoms will often dissipate after a few hours of being awake. One thing this can be due to is a condition called #lagophthalmos. This is a condition in which the patient sleeps with their eyes partially open. Therefore during the night the eyes dry out and the patient awakens to severe discomfort. A few ways to combat this problem are to tape the eyelids shut with medical tape before bed, or use a thick artificial tear ointment immediately before going to bed. This ointment protects the eye's surface from drying out due to environmental exposure. The only real way to tell if you suffer from this condition is to have someone look at your eyes while you are sleeping. The first step is to call your Optometrist to see if lagophthalmos may be the cause of your morning eye irritation.

The Lens of the Eye

The lens of the eye or often called the natural lens, is a transparent bioconvex structure positioned behind the pupil. The lens and the corneal are the predominate refracting surfaces of the eye.....that is they provide the power or our prescription in order to see. The internal structure of the lens allows for a large amount of elasticity to thicken or thin its size. This property of elasticity provides the eye the increased power to do most near tasks, as in reading. However, as we age, the lens gradually loses this elasticity, so by the age of 45 years, we have to supplement this loss with reading glasses. This decrease of elasticity or power is called presbyopia. Any loss in the transparency of the lens , which can greatly reduce our vision, is called an opacity or a cataract. We as optometrists during a normal comprehensive vision examination will evaluate the elasticity and transparency of the lens.

Winter Sunglasses are Must Have!

Now that we are in the winter months, many people don't think about sunglasses. They consider them summertime eyewear. However, sunglasses may be even more important in the winter. When snow is on the ground, sunlight and therefore UV radiation reflects off of it into our eyes.This can be worse than in the summer, when sunlight only comes from above. What can be particularly helpful, is a polarized sunglass lens, as these will help cut the blinding glare off the snow's surface.

My Eyes are Changing!

Many people around the age of forty go to the eye doctor after noticing that their near vision is blurry, often requiring them to push their reading material farther away. The is caused by a natural aging change called presbyopia. Presbyopia causes the natural crystalline lens within the eye to slowly harden. Until now, the lens is flexible and changes shape, with the help of the muscles that surround it, to allow for focusing at different focal distances. As the lens hardens, the focal distance becomes set at distance instead of near. This happens gradually from about age forty to fifty five. During this time is when people will notice a benefit from reading glasses or bifocals.
