Corneal Problems

Corneal Aging Changes 

My grandma can spot a needle in a haystack, but she has a white ring on her eye. I worry about it. Can you tell me what that is?

Commonest change seen with aging is the white ring at the limbus, called 'arcus senilis'. Occurs after 60 years. It is harmless.

Corneal dystrophy -

The ones that occur more commonly in adult age are :-

Fuch's corneal dystrophy -

In this the endothelial cell layer is damaged, and cornea gets swollen up with water, thus affecting vision. If eyedrops do not relieve it, corneal transplant may be required.

Keratoconus -

This can start at a younger age. The cornea becomes more and more conical, adversely affecting vision. To diagnose Keratoconus Corneal Mapping may be used.

The management in the initial stages consists of contact lenses.

In advanced stage, Corneal transplant is the only remedy.
