Episcleritis

Definition of Episcleritis

Episcleritis is irritation and inflammation of the episclera, a thin layer of tissue covering the white part (sclera) of the eye. It occurs without an infection.

Causes, incidence, and risk factors

Episcleritis is a common condition that is usually mild.

Signs and tests

An eye examination can usually diagnose the disorder. No special tests are usually necessary.

Treatment

The condition usually disappears without treatment in 1 – 2 weeks. Treatment with corticosteroid eye drops may relieve the symptoms faster.

Expectations (prognosis)

Episcleritis usually improves without treatment. However, treatment may make symptoms go away sooner.
