Definition of uveitis?
Uveitis is the inflammation of the uvea, a part of the eye.
Description of Uveitis
The eye is shaped much like a tennis ball, hollow inside with three different layers of tissue surrounding a central cavity. The outermost is the sclera (white coat of the eye) and the innermost is the retina (image-gathering tissue in the back of the eye much like the film in a camera).
The middle layer between the sclera and the retina is called the uvea, from the Greek word "uva" meaning grape. In the laboratory, it looks much like a "peeled grape." When the uvea becomes inflamed, the condition is called uveitis.
The uvea contains many of the blood vessels which nourish the eye. Inflammation of the uvea can affect the cornea, the retina, the sclera, and other vital parts of the eye.
Since the uvea borders many important parts of the eye, inflammation of this layer may threaten sight more seriously than the more common inflammation of the outside layers of the eye.
When the uvea is inflamed near the front of the eye in the iris, it is called iritis. If the uvea is inflamed in the middle of the eye involving the ciliary body, it is called cyclitis. If the inflammation is in the back of the eye affecting the choroid, it is called choroiditis.
