Iritis is inflammation of the pigmented inside lining of the eye (uvea), iris, or both.

Symptoms may include tearing, redness of the eye, and a painful ache in the eye. Usually people have some blurred vision or pain when exposed to bright light (photophobia).

Treatment

  • Drugs to relieve pain and decrease inflammation

Drugs that dilate the pupil are instilled into the eye. The drug relaxes the muscles of the colored part of the eye (iris), which spasm painfully. These drugs are called cycloplegics and include cyclopentolate and homatropine.

Corticosteroid eye drops (such as prednisolone) are often used to shorten symptom duration. Cycloplegics and corticosteroids are usually adequate to relieve pain, but if necessary, the person can also take acetaminophen.
