Long-term use of Aspirin may slightly raise the risk of developing age-related muscular degeneration, a leading cause of blindness among the elderly, a new study suggests. The study found that the potential risk is small but statistically significant "and needs to be balanced with the significant morbidity and mortality of undertreated cardiovascular disease," said study senior researcher Jie Jin Wang, a senior research fellow at the Center for Vision Research at the University of Sydney. The report, published Jan. 21st in the online edition of the journal JAMA Internal Medicine, collected data on more than 2,300 people. Regular Aspirin use was defined as once or more a week. As part of the study, the participants had four eye exams over 15 years. People taking Aspirin for heart and stroke prevention benefits should not be alarmed, however, Wang said.
