Purpose-To evaluate the outcomes of cyclophosphamide therapy for non-infectious ocular inflammation.
Design-Retrospective cohort studyParticipants-Two hundred fifteen patients with non-infectious ocular inflammation observed from initiation of cyclophosphamide.Methods-Patients initiating cyclophosphamide, without other immunosuppressive drugs (other than corticosteroids), were identified at four centers. Dose of cyclophosphamide, response to therapy, corticosteroid-sparing effects, frequency of discontinuation and reasons for discontinuation were obtained by medical record review of every visit.Main Outcome Measures-Control of inflammation, corticosteroid-sparing effects, discontinuation of therapy.

NIH-PA Author ManuscriptResults-The 215 patients (381 involved eyes) meeting eligibility criteria carried diagnoses of uveitis (20.4%), scleritis (22.3%), ocular mucous membrane pemphigoid (45.6%) or other forms of ocular inflammation (11.6%). Overall, approximately 49.2% (95% confidence interval (CI): 41.7%-57.2%) gained sustained control of inflammation (for at least 28 days) within 6 months, and 76% (95% CI: 68.3%-83.7%) within 12 months. Corticosteroid-sparing success (sustained control of inflammation while tapering prednisone to 10 mg or less among those not meeting success criteria initially) was gained by 30.0% and 61.2% by six and 12 months respectively. Disease remission leading to discontinuation of cyclophosphamide occurred at the rate of 0.32/person-year (95% CI: 0.24 -0.41), and the estimated proportion with remission at or prior to 2 years was 63.1% (95% CI: 51.5%-74.8%). Cyclophosphamide was discontinued by 33.5% of patients within one year because of side effects-usually of a reversible nature.Conclusions-Our data suggest that cyclophosphamide is effective for the majority of patients for controlling inflammation and allowing tapering of systemic corticosteroids to 10 mg of prednisone or less, although a year of therapy may be needed to achieve these goals. Unlike with most other immunosuppressive drugs, disease remission was induced by treatment in the majority of patients who were able to tolerate therapy. In order to titrate therapy properly and to minimize the risk of serious potential side effects, a systematic program of laboratory monitoring is required. Judicious use of cyclophosphamide appears bene...
