The Association of Race With Childhood Uveitis

Abstract

Purpose: To identify risk factors for a severe uveitis course among children with noninfectious uveitis.

Design: Retrospective cohort study.

Method: This was a retrospective analysis of a prospectively collected database. Records of 94 children with uveitis were reviewed at enrollment and every 3-6 months (2011-2015). Severe uveitis was defined as a history of ocular complications or a visual acuity (VA) of ≤20/200. Children were compared by disease, VA, complications, and race. Regression models were used to model risk factors for severe disease. When examining race, we focused on non-Hispanic African-American and non-Hispanic white children only.

Results: Of 85 children with uveitis and complete ocular examinations, 27 (32%) had a history of a VA of ≤20/200. A subanalysis of non-Hispanic African-American and white children showed an increased prevalence of VA ≤20/200 in non-Hispanic African-Americans (18/25; 72% vs 4/43; 9%). Non-Hispanic African-Americans were more likely to be diagnosed at an older age (P = .030) and to have intermediate uveitis (P = .026), bilateral disease (P = .032), a history of VA ≤20/50 (P = .002), VA ≤20/200 (P < .001), and a higher rate of complications (P < .001). On multivariable analysis, non-Hispanic African-American race was a significant predictor of blindness (OR = 31.6, 95% CI 5.9-168.5, P < .001), after controlling for uveitis duration. Non-Hispanic African-Americans also developed 2.2 times more unique complications per year of disease than non-Hispanic whites when controlling for uveitis type and duration.

Conclusions: There appear to be racial differences in the outcomes of children with uveitis. Non-Hispanic African-American children with non-juvenile idiopathic arthritis-associated uveitis may have worse visual outcomes with increased vision loss and ocular complications. These findings highlight the need for future studies in minority populations.
