Iritis (i-RYE-tis) is inflammation that affects a part of your eye called the iris. The iris is the colored ring of tissue surrounding your pupil. It's part of the middle layer of the eye known as the uvea, which is why this condition is considered a type of uveitis (u-ve-I-tis), or inflammation of the uvea. Because the iris is located at the front of the uvea, iritis is sometimes called anterior uveitis.
The cause of iritis is often unknown. But sometimes, iritis results from an underlying condition or genetic factor.
Iritis is a serious condition that, if left untreated, could lead to glaucoma or blindness. If you have symptoms of iritis, see your doctor as soon as possible for evaluation and treatment.

Tests and diagnosis
Before diagnosing iritis, your eye doctor will conduct a complete eye exam, including:
If your eye doctor suspects that a disease or condition is causing your iritis, he or she may work closely with your primary care provider to pinpoint the underlying cause. In that case, further testing may include blood tests or X-rays to identify or rule out specific causes.
Treatments and drugs
The main goals in treating iritis are to preserve vision and relieve any pain associated with the condition.
Most often, treatment for iritis involves:
If your symptoms don't clear up, or seem to get worse, your eye doctor might prescribe oral medications that may include steroids or other anti-inflammatory agents. However, taking the medicine orally has the potential to affect not only your eyes, but other parts of your body as well.
