Purpose
African Americans have a greater prevalence of open angle glaucoma (OAG) and exposure to traffic-related air pollution (TRAP). We investigated whether glaucomatous vascular changes were related to exposure of nitrogen dioxide (NO2) and particulate matter with aerodynamic diameter < 2.5 µm (PM2.5) in the African American Eye Disease Study (AFEDS).
Methods
The AFEDS is a cross-sectional, population-based cohort study conducted from 2014–2018 of 6,347 self-reported African Americans aged 40 years or older residing in 32 US census tracts of Inglewood, California.
