Association of race/ethnicity with visual outcomes following acute optic neuritis: an analysis of the Optic Neuritis Treatment Trial.
IMPORTANCE Retrospective studies have demonstrated disparate outcomes following acute optic neuritis in individuals of African descent compared with individuals of white race/ethnicity. However, published analyses of the prospectively collected Optic Neuritis Treatment Trial (ONTT) data identified no association between worse visual outcomes and black race/ethnicity. OBJECTIVES To investigate the associations of age, sex, and race/ethnicity with visual outcomes following acute optic neuritis through application of longitudinal data analysis techniques to the ONTT data set. ⋯ Race/ethnicity was significantly related to contrast sensitivity (P < .001) and visual acuity (P < .001) during a 15-year period following acute optic neuritis, with black race/ethnicity being associated with worse scores for both. CONCLUSIONS AND RELEVANCE Race/ethnicity seems to be associated with contrast sensitivity and visual acuity outcomes in affected eyes following acute optic neuritis. To our knowledge, this is the largest cohort of black race/ethnicity with acute optic neuritis to be studied and represents the first evidence from a prospectively collected data set to support a hypothesis of race/ethnicity-dependent visual outcomes of acute optic neuritis.
