What Are Iris Defects?

What are iris defects?

Iris defects refer to aniridia, a rare iris abnormality characterized with a complete or partial absence of the iris.

The most common symptoms are glare and photophobia. Others include reduced visual activity, reduced contrast sensitivity, and weakening of the body.

There are two types of iris defects: acquired or congenital. Acquired iris defects are due to injuries, while congenital ones are related with mental retardation. In general, acquired iris defects are more common than congenital ones. And, when it comes to treatment, special glasses and surgeries help.
