Chua SYL, Warwick A, Peto T, et al. - In this cross-sectional study, researchers sought to investigate the correlations of air pollution with both self-reported age-related macular degeneration (AMD), and in vivo measures of retinal sublayer thicknesses. The sample consisted of 115,954 UK Biobank participants aged 40–69 years old. Ambient air pollution measures involved particulate matter, nitrogen dioxide (NO₂) and nitrogen oxides (NO_x). According to findings, greater exposure to PM_2.5 was correlated with self-reported AMD, whereas PM_2.5, PM_2.5 absorbance, PM₁₀, NO₂ and NO_x were all related to differences in retinal layer thickness.
