Aim: To assess the prevalence, clinical characteristics, treatment, and outcomes of patients who developed ulcerative keratitis (UK) during the course of rheumatoid arthritis (RA) in the modern biologic era. Method: We retrospectively reviewed the medical records of 589 patients with RA who visited our department between April 2003 and October 2014, and identified patients who developed UK. We also obtained data about clinical characteristics of RA and UK, complications, treatment, and both visual and life prognoses of these patients. Results: Among 589 patients with RA, eight patients (1.4%) were diagnosed with UK. The mean age at the onset of RA was 61.0 years, while the mean age at the onset of UK was 73.0 years. Most of the patients were seropositive and had established RA with a relatively low disease activity. Secondary Sj€ogren's syndrome was observed in two patients. Peripheral UK occurred as a complication of scleritis, while central UK was not associated with scleritis. Although the mean duration of follow-up was only 3.7 years, visual and life prognoses were both tolerable with therapy, including the use of topical and systemic corticosteroids and calcineurin inhibitors, sometimes combined with biologic disease-modifying antirheumatic drugs (DMARDs) and corneal transplantation. Conclusion: This retrospective study demonstrated that the prevalence of UK in patients with RA was 1.4%. Immediate combination therapy, including topical and systemic corticosteroids and calcineurin inhibitors, together with biologic DMARDs and corneal transplantation, was effective for treating RA patients who developed UK in the modern biologic era.
