Review of 41 studies links fine-particle air pollution to higher odds of glaucoma and cataracts
A review of 41 observational studies found that people with the highest exposure to fine particulate pollution (PM2.5) had 70% higher odds of glaucoma than those with the lowest, according to findings presented in September at a European eye surgeons' congress in London, Live Science reported. The studies, involving millions of people in East Asia and the U.K., can show only a link, not that pollution causes the diseases, and epidemiologist Nidhi Singh, who was not involved, said the results show "an association, not by themselves a causal effect." A rise in PM2.5 exposure from the 25th to the 75th percentile within each study was associated with 8% higher odds of glaucoma and a 4% higher hazard of cataracts, and the evidence was less consistent for macular degeneration and for other pollutants. The report gives relative differences only, with no absolute rates, and does not say whether the work has been published in a journal.
