Uveitis is the inflammation of the uvea, a part of the eye.
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.
Causes and Risk Factor of Uveitis
Uveitis has many different causes. It may result from a bacteria (Tuberculosis), virus (such as shingles, mumps or herpes), a fungus (such as histoplasmosis), or a parasite (such as toxoplasmosis). In most cases, the cause remains unknown.
Uveitis can also be related to disease in other parts of the body, such as arthritis, or come as a consequence of injury to the eye.
Symptoms of Uveitis
Symptoms include light sensitivity, blurring of vision, pain, and redness of eye. Uveitis may
come on suddenly with redness and pain, or it may be slow in onset with little pain or redness, but gradual blurring of vision.
