Episcleritis is an inflammation of one of the surface layers of the eye. The front, white part of the eye called the sclera is covered by transparent membrane called the conjunctiva. Between these is another transparent layer called the episclera. When this is inflamed it is known as episcleritis.
The cause is unknown in most cases. It normally affects only one eye and is a benign condition that does not damage your sight.
Episcleritis usually resolves spontaneously in about two weeks. Occasionally anti-inflammatory drops are prescribed to hasten resolution.
Unfortunately episcleritis frequently recurs for several years before eventually stopping.
