Stagg B, Mariottoni EB, Berchuck S, et al. - Utilizing data from 1,103 eyes from 751 White people and 428 eyes from 317 black people, researchers conducted this retrospective observational cohort study to examine racial differences in the variability of longitudinal visual field testing in a ‘real-world’ clinical population, assess how these differences are influenced by socioeconomic status, and estimate the effect of differences in variability on the time to detect visual field progression. When compared with white patients, black patients had larger visual field variability. This relationship was strongly influenced by socioeconomic status, which may explain some of the racial disparities in glaucoma outcomes.
