Overview
The sclera (say "SKLAIR-uh") is the white of the eye. It protects the eye's inner parts. There are several layers of the sclera. The episclera (say "eh-puh-SKLAIR-uh") is the top layer.
Episcleritis (say "eh-puh-skluh-RY-tus") means that the episclera is inflamed. The inflammation makes all or part of the white of the eye look red. For some people, the eye feels tender, hot, or irritated.
Episcleritis is not a serious eye problem. It doesn't damage your eye or harm your vision. Usually it starts suddenly, and the cause isn't known. Some people already have a health problem that could be related, such as rheumatoid arthritis or an infection.
To see if you have episcleritis, your doctor checks your vision. The doctor looks closely at your eyes and talks to you about your symptoms. You may have tests and X-rays to look for medical problems that might be linked to your eye problem.
Episcleritis usually goes away on its own in a few days, though it can take a few weeks. Your doctor may prescribe eyedrops to help relieve the inflammation.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
