Objectives. (1) To review the visual and systemic outcomes of patients who developed rheumatoid arthritis (RA)-associated peripheral ulcerative keratitis (PUK). (2) To describe the clinical and serological characteristics of the patients' arthropathy at the time of presentation of this rare condition. (3) To review the aetiology and management of RA-associated PUK.
Patients and methods. A case series is given of all nine patients within our unit who have developed RA-associated PUK since 1996. Details of the patients' arthropathy and the serological characteristics of the RA at presentation of PUK were noted. The patients' visual outcomes and the development of any significant systemic complications were recorded.
Results. All patients had long-standing seropositive, erosive RA. PUK was associated with a poor visual outcome in most patients, five requiring emergency corneal surgery to prevent perforation of the globe. Two patients developed systemic vasculitis within 1 month of PUK onset, one of whom died.
Conclusion. RA-associated PUK often has a poor visual outcome and its appearance may herald the transformation of a patient's RA into the systemic vasculitic phase. RA-associated PUK should be managed with aggressive immunosuppression if the associated morbidity and mortality are to be avoided. Cell-mediated mechanisms appear to be important in the aetiopathogenesis of PUK and a combination of corticosteroids and cyclosporin is therefore probably the regimen of choice.
