What you need to know about iritis

The iris is the colored portion of the eye that is responsible in controlling the diameter of the pupil. This part of the eye controls how much light enters the pupil and reaches the retina, which affects how well we see things. When the iris becomes inflamed due to many different reasons, iritis occurs.

Iritis can be a result of many different things, including trauma. A single but sharp blow in the eye could cause your iris to be inflamed. According to a Mokaram & Associates, P.C. website, eye trauma can be a result of automobile accidents, defective airbags, or dangerous eye solutions. Apart from trauma, iritis can also be a result of one or more of these:

  • Infections – Tuberculosis and syphilis have been associated with iritis. Shingles may also increase your risk of this eye condition
  • Certain medications – Certain antibiotic and antiviral medications may trigger iritis.
  • Underlying medical conditions – These include Behcet’s disease and juvenile rheumatoid arthritis
  • Genes – Some genetic alteration may cause certain autoimmune diseases, such as sarcoidosis, which triggers iritis

People with an inflamed iris may experience eye redness and pain, photosensitivity, and blurred vision. If not diagnosed and treated immediately, iritis may lead to other more serious eye complications. These include cataracts, glaucoma (pressure build-up inside the eye), macular edema (swelling in the retina), and keratopathy (corneal disease caused by calcium build-up). All these complications may profoundly compromise your vision, and may even result in irreversible blindness.

If you think you are at higher risk of iritis and are suffering from one or more symptoms above, you should visit your ophthalmologist immediately for quick diagnosis. Your doctor will typically start with a complete eye exam followed by external examinations of the eye, such as glaucoma test and split lamp test. After an iritis diagnosis, your doctor may then recommend dilating eye drops or steroid eye drops to get rid of pain and inflammation.
