ABSTRACT
Scleritis is a condition that sits uneasily in the uveitis clinic. The sclera is not a part of the uveal tract and scleritis itself presents differently to uveitis and is treated differently. Inflammation of the sclera itself is called scleritis. Scleritis is classified by location, with anterior affecting the sclera that can be seen and posterior affecting the sclera that cannot. Distinguishing episcleritis from anterior diffuse scleritis can be tricky. Every eye department in the world has a steady stream of worried young women presenting with a unilateral red eye that is diagnosed as episcleritis. Unlike episcleritis half of all cases of scleritis are associated with a systemic disease and the most common disease is rheumatoid arthritis. While uveal effusion syndrome is most certainly not a uveitic condition it is mentioned here as it can cause some diagnostic confusion, particularly in the case of posterior scleritis.
