Episcleritis is an inflammation of the episclera, a membrane covering the sclera of the eye.
The sclera is composed of collagenous fibres to form a white, hollow ball. It is the â€˜skeletonâ€™ of the eyeball and is covered by the episclera, a thin layer of tissue containing many blood vessels that nourish the sclera. On the front of the eye, the episclera is covered by the conjunctiva. Inflammation of the episclera is usually mild and usually does not progress to the more serious, scleritis.
The cause is unknown, but certain diseases such as rheumatoid arthritis, Sjogrenâ€™s syndrome, syphilis, herpes zoster, and tuberculosis have been associated with episcleritis. It is a common condition.
Although usually self limiting, episcleritis can progress into a more serious condition so it is important to have any red or sore eyes examined by a professional.
