Episcleritis
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.

Causes
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:
- Herpes zoster
- Rheumatoid arthritis
- Sjögren syndrome
- Syphilis
- Tuberculosis
-
Symptoms
Symptoms include:
- A pink or purple color to the normally white part of the eye
- Eye pain
- Eye tenderness
- Sensitivity to light
- Tearing of the eye
-
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.
-
Treatment
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
Contact your 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.
