Iritis Overview

The iris is a circular, pigmented membrane that provides the eye its color and forms the pupil of the eye.

The iris is made up of muscular fibers that control the amount of light entering the pupil so that we can see clearly. The iris accomplishes this task by making the pupil smaller in bright light and larger in dim light.

In some people, the iris can become inflamed. This is termed iritis.
