Iritis

The iris is the coloured part of the eye. It is composed of muscular fibers that control the amount of light that enters your eye so that you an see clearly. The circular opening in the iris is called the pupil. If the iris becomes inflamed, this is termed iritis.

Iritis

Symptoms

  • Pain in the eye or around the eye
  • Pain is increased in bright light
  • Reddened eyes, especially adjacent to the iris
  • Possibly small or unusual shaped pupil
  • Headache
  • Blurred vision   

Causes

  • Blunt trauma can cause traumatic inflammation of the iris
  • Infectious cause may include Lyme disease, herpes simplex or herpes zoster(shingles), tuberculosis
  • Iritis can be associated with certain diseases such as sarcoidosis, inflammatory bowel disease, psoriasis
  • In most cases, no cause can be found

Treatment

  • Drops are used to dilate the pupil to prevent spasm of the iris muscles so the inflamed iris can rest.  This allows healing and also helps relieve pain.
  • Steroid eye drops are also used to decrease the inflammation of the iris.
  • The length of treatment depends on the severity of the iritis .
