To understand what uveitis is, it is helpful to understand the anatomy of the eye. Shaped like a tennis ball, the eye is made up of three different layers of tissue that surround the central gel-filled cavity (vitreous gel). The outer layer is the sclera; the middle layer is the uvea; and the innermost layer is the retina. The uvea contains many blood vessels that carry blood to and from the eye. The iris is a specific part of the uvea and is seen as the colored part of the eye behind the cornea, or clear surface of the eye.  Uveitis is when the uvea becomes inflamed. This inflammation can cause pain and/or loss of sight.

There are a number of symptoms of uveitis, including:

• Pain
• Floaters
• Light sensitivity
• Redness of the eye
• Blurred vision
