Support us All Our Appeals Uveitis Appeal Donate Fundraise Uveitis is a sight threatening chronic inflammation of the eyes that is difficult to treat effectively and safely. It belongs to a group of illnesses grouped together as “autoimmune diseases” in which the body’s normal defence mechanisms, that protect against foreign bodies, ‘turn’ against the body itself, just as if it were fighting an infection. This perverted response can cause terrible damage to the body’s tissues or organs. These diseases include rheumatoid arthritis in the joints and ulcerative colitis and Crohn’s disease which attack the bowel. In the eye it causes Uveitis. Treatment of the condition is difficult, extended and can cause significant side effects. We urgently need to find more effective and safer treatments.
