What it is
Uveitis is inflammation of the uvea, the middle layer of the eye that includes the iris. It can come on suddenly or develop gradually, and because it can affect vision if untreated, it should be assessed quickly by an eye specialist.
Common symptoms
Symptoms can affect one or both eyes.
- Eye pain and redness
- Sensitivity to light
- Blurred or cloudy vision
- Floaters or a small, irregular pupil
Causes and risk factors
Uveitis is often linked to autoimmune or inflammatory conditions, and sometimes to infections or eye injury. In many cases no specific cause is found. It can affect people of any age.
Treatment
Uveitis is usually treated by an eye specialist with steroid eye drops or other anti-inflammatory treatment to settle the inflammation and prevent complications. Prompt treatment and follow-up are important, and any underlying condition may also need managing. Seek urgent advice for a painful red eye with light sensitivity or blurred vision.
