Uveitis and autoimmune diseases are closely related. Autoimmune diseases are diseases that result from autoimmunity, and the most representative autoimmune disease is rheumatoid arthritis. Autoimmune diseases are often systemic, meaning that different organs throughout the body may be attacked, such as rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel diseases (ulcerative colitis and Crohn`s disease), scleroderma, recurrent polychondritis, etc. The physician must first determine the cause of uveitis and the effective treatment of the disease. The cause of uveitis can be diagnosed by various laboratory tests (blood biochemical and immunological tests, tuberculin tests, X-ray examinations (including chest X-ray, spinal photographs), etc.). Treatment includes: 1. treatment of the primary disease; 2. relief of pain and discomfort; 3. prevention of post-pupillary adhesions; 4. prevention of various complications, which can be treated surgically such as complicating cataracts, secondary glaucoma, retinal detachment, etc., in order to prevent the resulting loss of vision. Local and systemic application of cholesterol-like drugs is the main treatment, while others include pupil dilatation and the application of immunosuppressive and nonsteroidal anti-inflammatory drugs. Treatment is prolonged in some severe cases.
