Iritis

Iritis (i-RYE-tis) is inflammation that affects the coloured ring around your eye's pupil (iris). The iris is a part of the middle layer of the eye (uvea), so iritis is a type of uveitis, also known as anterior uveitis. Iritis, the most common type of uveitis, affects the front of your eye. The cause is often unknown. It can result from an underlying systemic condition or genetic factor. Iris can occur in one or both eyes. It usually develops suddenly, and can last six to eight weeks. Signs and symptoms of iritis include: - Eye redness - Discomfort or achiness in the affected eye - Sensitivity to light (photophobia) - Decreased vision
