Iritis is the inflammation of the iris of the eye. Because of this disorder, microscopically small white cells from the inflammation area (along with an increased amount of protein that emerge from the small blood vessels in the iris) float in the aqueous humour between the iris and the cornea. If there are many floating cells, they can stick to the back of the cornea or settle down on the bottom of aqueous humour. The cause of iritis is not known, but the disorder may sometimes occur along with a variety of diseases including, for example, rheumatoid arthritis and ankylosing spondylitis. Iritis can affect one or both eyes.
The main symptom is a feeling of disturbance in the eye that turns red. This is accompanied by a slight decrease in vision. If the eye pressure increases, pain can occur, although most commonly all symptoms are mild.
Iritis is not a common disorder. Annually, only one in 2000 people seek medical attention because of this discomfort. Disease occurs at every age, but most often in young adults.
If treated early, iritis is usually not a serious disorder. However, if you do not seek medical attention, complications may develop. In the aqueous humour, so many white cells can accumulate to block the opening through which the fluid drains out of the ey,e causing a type of glaucoma. This complication can also develop if the back part of the inflammed iris is attached to the front of the lens, resulting in stopping the flow of aqueous humour behind the iris. Long-lasting iritis can cause cataract.
What to do?
When you notice any sign of redness, disturbance and loss of vision, however weak it is, contact your doctor. If your doctor finds you have an iritis, keep the following advice: as soon as you start treatment, it will be easier to overcome the disease, and the likelihood that complications will occur will be smaller.
Corticosteroid eye drops or corticosteroid fat are given to relieve inflammation; in severe cases, corticosteroids may be injected between the ocular joint and pancreas with local anesthesia. You will also get droplets to enlarge the pupil to prevent the ”attaching” of the back of the inflammed iris with the front part of the lens. Possible increase in eye pressure is regulated by tablets.
Despite early treatment, iritis often returns, although the disorder generally disappears in time.
