Fine particulate matter linked to increased glaucoma and cataract risks

A meta-analysis of 41 studies involving millions of participants has identified a significant link between exposure to fine particulate matter (PM2.5) and an increased risk of serious eye diseases, specifically glaucoma and cataracts.

Presented at the European Society of Cataract and Refractive Surgeons (ESCRS) congress in London, the research conducted by the King Khaled Eye Specialist Hospital indicates that individuals in regions with the highest air pollution levels face up to a 70 percent higher likelihood of developing glaucoma compared to those in areas with the lowest pollution.

The findings also show a consistent increase in cataract risk in highly polluted regions. Data suggests a granular dose-effect, where even measurable increases in pollutant exposure correlate with higher risks. In contrast, the evidence regarding age-related macular degeneration (AMD) remains inconsistent across the studied datasets.
