Definition

Alternative Names

Causes, incidence, and risk factors

Episcleritis is a common condition that is usually mild.

The cause is usually unknown, but it may occur with certain diseases, such as:

• Herpes zoster
• Rheumatoid arthritis
• Sjogren syndrome
• Syphilis
• Tuberculosis

Symptoms

• A pink or purple color to the normally white part of the eye
• Eye pain
• Eye tenderness
• Sensitivity to light
• Tearing of the eye

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.

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.

Calling your health care provider

Call your health care provider if you have symptoms of episcleritis that last for more than 2 weeks. Get checked again if your pain worsens or you lose vision.
