Destructive corneal and scleral disease associated with rheumatoid arthritis. Medical and surgical management.

The onset of necrotizing scleritis (NS) and peripheral ulcerative keratitis (PUK) in the clinical course of rheumatoid arthritis (RA) may reflect the presence of systemic, potentially lethal vasculitis. In an effort to better characterize this subset of patients with severe RA-associated corneal and/or scleral inflammation and to analyze the efficacy of therapy, we reviewed our experience in the medical and surgical management of 16 tertiary referral cases (25 eyes) unresponsive to aggressive conventional therapy with topical and systemic steroids as well as with systemic nonsteroidal drugs. Cytotoxic immunosuppressive therapy was instituted in all patients with NS and/or PUK. Cyclophosphamide and methotrexate were the most successful agents used. Cytotoxic immunosuppressive drugs in conjunction with early aggressive surgical treatment halted the relentlessly progressive inflammation and preserved the integrity of the globe in 92% of eyes. Visual acuity could be stabilized or improved in 83% of patients with NS and in 68% of patients with PUK.
