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.
