A large European study, published in the January issue of the journal of the American Academy of Ophthalmology, links daily aspirin use to increased risk of age-related macular degeneration (AMD).

The study found that people aged 65 and older who took aspirin daily had double the risk of developing “wet” AMD (an advanced form of the disease that occurs when abnormal blood vessels grow and bleed or leak fluid into the macula), compared with those who took it less frequently. The study also found a somewhat elevated risk of early-stage AMD in daily aspirin users. No higher risk was found for advanced “dry” AMD.
