Episcleritis is irritation and inflammation of the episclera, a thin layer of tissue covering the white part (sclera) of the eye. It is not an infection.


Episcleritis is a common condition. In most cases the problem is mild and vision is normal.

The cause is often unknown. But, it may occur with certain diseases, such as:


Symptoms include:

Exams and Tests

Your health care provider will do an eye exam to diagnose the disorder. Most of the time, no special tests are needed.


The condition most often goes away on its own in 1 to 2 weeks. Using corticosteroid eye drops may help ease the symptoms faster.

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.

When to Contact a Medical Professional

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