[Effects of air pollution on eye health].

Abstract

EFFECTS OF AIR POLLUTION ON EYE HEALTH. In addition to its well-known effects on cardio-respiratory health, air pollution could also have an impact on eye health. Indeed, certain air pollutants, especially fine particles and nitrogen dioxide, can enter the bloodstream, triggering oxidative and inflammatory mechanisms involved in the development of the major eye diseases (glaucoma, age-related macular degeneration [AMD], cataracts). Over the past 5 years, some 15 epidemiological studies carried out in Asia, Europe and Canada have consistently shown an increased risk of these diseases in individuals most exposed to air pollution at long term, particularly to fine particles. These results support the lowering of air pollution thresholds recommended by the World Health Organization (WHO) in 2021, which nevertheless continue to be exceeded in most European cities.
