Uveitis is a condition in which patients develop inflammation on the inside of the eye. Uveitis can result from infectious diseases, malignancy (cancer), or autoimmune conditions. Symptoms of uveitis include blurry vision, hazy vision, pain or redness. Certain types of uveitis require extensive blood work and diagnostic tests to determine the cause. Sometimes a biopsy of the fluid in the eye is required to make the diagnosis. This can sometimes be done in the office but often is done in the operating room. Patients with certain types of uveitis will also be referred to a rheumatologist for evaluation of the immune system.
