Purpose-To investigate the risk of cataract development among patients with juvenile idiopathic arthritis (JIA)-associated uveitis treated with topical corticosteroids.
Design-Retrospective cohort studyParticipants-75 patients with JIA-associated uveitis observed from July 1984 through August 2005 at a single academic center.Methods-Clinical data on these patients were collected by chart review and were analyzed.Main outcome measures-Incidence of new-onset cataract. Risk factors for cataract development were assessed with attention paid to the use of topical corticosteroids.Results-Over a median follow-up of 4 years, the incidence of new-onset cataract was 0.04/eyeyear (EY, 95% confidence interval [CI]: 0.02/EY, 0.09/EY). Of the 60 eyes in 40 patients who received topical corticosteroid therapy, there was a dose-dependent increase in the rate of cataract development among eyes receiving topical corticosteroids. The incidence of cataract was 0.01/EY for eyes treated with ≤ 3 drops daily and 0.16/EY (P = 0.0006 for log rank test) for eyes treated with >3 drops daily. Among eyes receiving ≤ 2 drops daily, the incidence of cataract was 0/EY (95% CI, one-sided: 0.03/EY). Presence of posterior synechiae, active uveitis, and use of topical corticosteroids at presentation were statistically significantly associated with cataract development after controlling for confounding variables. Use of topical corticosteroids was associated with cataract formation independent of uveitis activity. Using longitudinal data analysis and controlling for duration of uveitis, presence and degree of active uveitis, and concomitant use of other forms of corticosteroids in a time-updated fashion, treatment with ≤ 3 drops daily of topical corticosteroid was associated with an 87% lower risk of cataract formation compared to eyes treated with >3 drops daily (relative risk = 0.13, 95% CI: 0.02, 0.69, P = 0.02).Corresponding Author: Jennifer E.

Published in final edited form as:Ophthalmology. Conclusions-In our cohort, topical corticosteroid use was associated with an increased risk of cataract formation independent of active uveitis or presence of posterior synechiae. However, chronic use of topical corticosteroids dosed at ≤ 3 drops daily appeared to be associated wi...
