Uveitis and Iritis

The eye has three different layers of tissue: the protective outer layer called the sclera, the middle layer called the uvea, and the inner layer called the retina. The iris, ciliary body and choroid form the uvea. Uveitis is an inflammation of any part of the uvea. Sometimes, uveitis affects other areas of the eye, for example, the retina, optic nerve or the lens.

Causes include infections or trauma. Other forms of uveitis are presumed to be “autoimmune”, where the body’s own immune system reacts against the body itself.

Uveitis can be acute (lasting days or weeks) or chronic. Some cases of uveitis can seriously affect vision and the long-term health of the eye. Permanent loss of sight can result, but these cases are uncommon.
