Dutch researchers, led by Dr. Paulus de Jong, conducted a study to see if aspirin exacerbates macular degeneration. Of the 839 people who took aspirin daily, approximately four out of every 100 had wet AMD. In comparison, about two out of every 100 people who took aspirin less frequently had the same type of AMD. Aspirin was not tied to the dry form.
Since aspirin is taken to prevent heart disease that condition might influence the results. For people with heart disease, the benefits of the drug outweigh the risk.
