What Is It?
Uveitis means inflammation of the part of the eye called the uvea. The uvea, also called the uveal tract, is a continuous layer of fibrous tissue that surrounds the eye. It is made up of three structures:
The iris — The donut-shaped part that gives the eye its color
The choroid — A membrane full of tiny blood vessels that lines the eye
The ciliary body — A thick ring of tissue that helps control the shape of the lens, and is attached to the iris and to the front portion of the choroid
Various terms are used for the condition, depending on the part of the uvea affected. They include:
