What is Uveitis?

The eye is shaped much like a tennis Ball, hollow inside with three different layers of tissue surrounding a central cavity. The outermost layer is the sclera (white coat of the eye). The innermost is the retina (the image gathering tissue at the back of the eye, like the film in a camera). The middle layer, between the sclera and the retina, is called the uvea, from the Greek word uvea, meaning grape. When the uvea becomes inflamed, the condition is called Uveitis. The front portion of the uvea is the iris. In the laboratory, it looks like a peeled grape.
