Outlook (Prognosis) Episcleritis most often improves without treatment. However, treatment may make symptoms go away sooner. Possible Complications In some cases, the condition may return. Rarely, irritation and inflammation of the white part of the eye may develop. This is called scleritis.

As light passes through the eye the iris changes shape by expanding and letting more light through or constricting and letting less light through to change pupil size. The lens then changes shape to allow the accurate focusing of light on the retina. Light excites photoreceptors that eventually, through a chemical process, transmit nerve signals through the optic nerve to the brain. The brain processes these nerve impulses into sight.External and internal eye anatomyillustrationExternal and internal eye anatomy - illustration The cornea allows light to enter the eye.
