Iritis (i-RIE-tis) is inflammation that affects your eye's iris, the colored ring surrounding your pupil. The iris is a part of the middle layer of the eye (uvea), so iritis is a type of uveitis, sometimes called anterior uveitis.

The cause of iritis is often unknown. Sometimes iritis results from an underlying systemic condition or genetic factor.

Iritis is a serious condition that, if left untreated, could lead to glaucoma or vision loss. If you have symptoms of iritis, see your doctor as soon as possible.

Symptoms Causes Risk factors Complications

Signs and symptoms of iritis may include:

  • Eye redness
  • Discomfort or achiness in the affected eye
  • Sensitivity to light (photophobia)
  • Blurred vision
  • Floating specks or spots in your vision

Iritis that develops suddenly, over hours or days, is known as as acute iritis. Symptoms that develop gradually or last longer than six weeks indicate chronic iritis.

When to see a doctor

See an eye specialist as soon as possible if you have symptoms of iritis. Prompt treatment helps prevent serious complications. If you're experiencing eye pain and vision problems with other signs and symptoms, you may need urgent medical care.
