A meta-analysis of 41 studies involving millions of participants has established a link between exposure to air pollution, specifically fine particulate matter (PM2.5), and an increased risk of developing glaucoma and cataracts.

Presented at the European Society of Cataract and Refractive Surgery congress in London, the research indicates that individuals in regions with the highest pollution levels may face up to a 70 percent higher likelihood of developing glaucoma compared to those in areas with the lowest pollution. While the research notes that aging and diabetes remain primary risk factors, the findings suggest a granular dose-effect where even measurable increases in pollutant exposure correlate with higher risks. The study noted that evidence regarding age-related macular degeneration remains inconsistent.
