Iritis

Iritis is an inflammation of the iris, the colored part of the eye. It is a form of anterior uveitis and is therefore sometimes referred to as anterior uveitis. Iritis can be caused by various conditions, including autoimmune disease, infection, and trauma to the eye. It is a serious condition that can lead to permanent vision loss if not treated promptly.

Causes

The exact cause of iritis is often unknown, but it can be associated with certain medical conditions. These include ankylosing spondylitis, psoriasis, inflammatory bowel disease, sarcoidosis, and Behçet's disease. Iritis can also be caused by an infection, such as herpes simplex, syphilis, or tuberculosis. In some cases, iritis can occur as a result of trauma to the eye.

Symptoms

Symptoms of iritis can vary, but often include eye pain, blurred vision, photophobia (sensitivity to light), and a red or pink eye. The eye may also appear cloudy. Symptoms can develop quickly and may become severe in a short period of time.

Diagnosis

Iritis is diagnosed through a comprehensive eye examination. This may include a slit lamp examination, in which a special microscope is used to examine the front of the eye. Other tests may be performed to rule out other conditions that can cause similar symptoms.

Treatment

Treatment for iritis aims to reduce inflammation, relieve pain, and prevent damage to the eye. This typically involves the use of corticosteroid eye drops to reduce inflammation. Other medications may be used to dilate the pupil and relieve pain. In some cases, oral medications or injections may be needed. If iritis is caused by an underlying condition, treatment for that condition will also be necessary.

Prognosis

With prompt treatment, most people with iritis can recover without permanent vision loss. However, iritis can recur, and repeated episodes can lead to complications such as glaucoma, cataract, and macular edema. Regular follow-up with an ophthalmologist is important to monitor for these complications.
