ABSTRACT

Eye involvement is a frequent finding in patients with rheumatoid arthritis and may represent the leading clinical manifestation of disease. In this context, all components of the visual organ might be affected. The main spectrum of eye involvement comprises keratoconjunctivitis sicca, episcleritis and scleritis as well as ulcerative keratitis. As with the underlying disease, autoimmune reactions based on a patient's genetic predisposition are assumed to be of significance in disease pathogenesis. Emerging evidence also points to additional morphological and physiological ocular characteristics in the pathogenesis of the various ocular pathologies. This article gives an overview of clinical aspects, pathogenetic background as well as therapeutic options for ocular involvement in rheumatoid arthritis.
