Is NSAID Use Linked to AMD?
American Journal of Ophthalmology, April 2018
Inflammation has been implicated in the pathogenesis of age-related macular degeneration (AMD), which suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) may modulate disease activity. To date, most research on the link between NSAIDs and AMD has focused on aspirin, and results have been conflicting. Modjtahedi et al. looked at the relationship between AMD and multiple types of NSAIDs. They found that, overall, NSAID use was not associated with a higher incidence of AMD—and that longer-term use was linked to a lower risk of wet AMD.
For this prospective cohort study, the researchers included participants of the California Men’s Health Study who completed surveys during 2002-2003 and 2006. NSAID use was defined as taking aspirin, ibuprofen, naproxen, celecoxib, rofecoxib, and/or valdecoxib at least 3 days a week. Patients were categorized as nonusers, former users, new users, or longer-term users. NSAIDs were classified as aspirin, non-aspirin NSAIDs, and any NSAID.
Of the 51,371 study participants, 292 (0.6%) had wet AMD, and 1,536 (3%) had the dry form of the disease. The average follow-up time was 7.4 years. Longer-term use of any NSAID was associated with lower risk of exudative AMD. New users of aspirin or any NSAID had a lower risk of nonexudative AMD, but this trend was not observed for longer-term users. No other meaningful relationships were noted.
Although longer-term use of any NSAID appears to carry a lower risk of exudative AMD, the authors emphasized that more research is needed to determine whether this finding can be applied clinically to modify disease risk.
