Uveitis is inflammation anywhere in lining of the eye, known as the uvea, or uveal tract. Uveitis can occur because of infection, autoimmune disorders (which causes the body to attack its own tissues), or for unknown reasons. An eye physician makes the diagnosis and treatment based on the symptoms and a complete physical examination. Depending on suspicion for diseases that also affects other organs, appropriate tests are done. Uveitis is a serious eye disease and can rapidly damage the eye. It can cause long-term, vision-threatening complications, such as glaucoma, and cataracts. Many people have only one episode of uveitis. Others may have periodic recurrences over months to years. All patients with a history of autoimmune disorders should be seen regularly by an eye doctor.
