Iritis is an inflammatory condition of the colored portion (the iris which surrounds the pupil) of the eye. It causes varying degrees of redness of the eye, often with significant pain, sensitivity to light, tearing, and blurred vision. Often no reason is found. An infection of the eye or inflammation from trauma may cause iritis. Iritis may also be a complication of many diseases such as juvenile rheumatoid arthritis, ankylosing spondylitis, tuberculosis, sarcoidosis, and collagen vascular diseases such as lupus. Iritis may occur with herpes simplex of the eye and after eye surgery. Iritis related to juvenile rheumatoid arthritis is especially dangerous and may not respond well to treatment, leading to serious eye damage. To see more details visit, www.medicinenet.com
