Uveitis. Close-up of the eye of a 43 year old man showing uveitis. It has caused the sclera (white of the eye) to become severely bloodshot. Uveitis is any inflammation of the uvea of the eye, which includes the iris (coloured part), the lens muscles and the blood vessels which supply the retina. This condition may be caused by an infection, although it is usually an autoimmune disorder, in which the body turns its defences against itself. Treatment involves taking corticosteroid drugs to reduce inflammation, and using eye drops containing atropine to block nerve impulses to the iris muscles.
