Rheumatoid arthritis is a systemic inflammatory disorder, which is a chronic disease that may affect many tissues and organs, but principally attacks flexible joints. Joint inflammation is characterized by redness, warmth, swelling, and pain within the joint. Symptoms of rheumatoid arthritis include joint pain and swelling, stiffness, especially in the morning or after sitting for long periods and fatigue. Rheumatoid arthritis is possible to cause eye pain and affect our eyes. As long as the immune system is triggered, immune cells migrate from the blood into the joints and joint-lining tissue. The inflammatory substances will cause irritation, wearing down of cartilage , and swelling and inflammation of the joint lining. That is, the blood and bones around eyes are also easy to be damaged by rheumatoid arthritis.
