What is the most common ocular side effect associated with Rheumatoid Arthritis?

Keratoconjunctivitis sicca is a common ocular side effect associated with rheumatoid arthritis primarily due to the autoimmune nature of the condition. In rheumatoid arthritis, the immune system can attack the glands that produce tears, leading to decreased tear production and resulting in dry eyes. This condition can cause dryness, irritation, and inflammation in the eyes, which matches the symptoms seen in keratoconjunctivitis sicca, also known as dry eye syndrome.

The prevalence of this ocular symptom is significant in patients with rheumatoid arthritis, making it the most frequently encountered ocular side effect in this population. This condition is often exacerbated by other factors such as environmental elements and can lead to discomfort and further complications if not managed appropriately.

Other ocular conditions associated with rheumatoid arthritis, such as retinal vasculitis or peripheral keratitis, are less common. Optic neuritis, while a serious condition, is rare in the context of rheumatoid arthritis and not typically linked to this systemic autoimmune disorder. Thus, keratoconjunctivitis sicca stands out as the primary ocular complication related to rheumatoid arthritis.
