Scleritis is an inflammation of the sclera (the white outer wall of the eye). Inflammation of the sclera is often linked to autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Sometimes the cause is unknown. Scleritis occurs most often in people between the ages of 30 and 60. It is rare in children. Symptoms of scleritis include: blurred vision, eye pain and tenderness, red patches on the normally white part of the eye, sensitivity to light, and tearing of the eye. A rare form of this disease causes no eye pain or redness. In most cases, the condition goes away with treatment. But it may come back. The disorder causing scleritis may be serious. However, it may not be discovered the first time you have the problem. The outcome will depend on the specific disorder.
