Often patients have noticed that their dark brown eyes are changing to blue at the edge. This is not actually the eye changing color, but a condition called arcus. The color of the eye comes from the pigment in the iris. This blue color is actually white cholesterol depositing in the cornea that looks blue when superimposed in front of the brown iris.
While this is very common in elderly patients, if seen in a younger patient, it should be a sign to have your cholesterol level checked. The cholesterol deposition in the cornea does not hamper vision because it is in the peripheral cornea rather than the central cornea, but it indicates cholesterol may be depositing elsewhere in the body, where it can have detrimental effects on health.
There are no other symptoms of this condition other than the ring that forms around the corneal periphery. This condition is painless and presents no further health risks for people over the age of 70. If this occurs in people under they age of 40, they could have other medical issues such as hypercholesterolemia, which is high levels of cholesterol in the blood.
If you or a loved one are experiencing this, you should consult your eye care professional and go in to get checked out.
