Iritis

Patient Information

Patient Information
Iritis (anterior uveitis)

Iritis is an inflammatory condition affecting the iris, (the coloured part of your eye). It can be associated with other inflammatory conditions of the body, for example arthritis, but in most cases the cause remains unknown.

It is a common condition which tends to recur, and usually only affects one eye at any one time.

Signs and symptoms

Aching, painful red eye with small pupil, blurred vision and sensitivity to light.

Treatment

It is important that this condition is treated quickly, it can be difficult to diagnose without certain equipment, which is often not available at your local doctor’s surgery.

The usual treatment is steroid drops which may be used frequently at first, then gradually tailed off. You must not suddenly stop using the drops, or the iritis may recur.

You will often be given drops to dilate your pupil. This will cause blurring of vision and difficulty in focusing, and may also increase your sensitivity to light, but it is a vital part of the treatment for iritis. If the pupil is not dilated, the inflamed iris will stick to the lens, which can lead to complications. In order to cause minimal inconvenience the dilating drops are usually used last thing at night.
