London: Regular intake of the `wonder drug` aspirin for 10 years could more than double the risk of sight loss, a new study has claimed.Scientists say taking aspirin could increase the chance of developing wet age-related macular degeneration (AMD) - an eye condition that can lead to blindness.Researchers from the University of Wisconsin used data from the Beaver Dam Eye Study on age-related eye diseases. Eye exams were performed every five years over a 20-year period on nearly 5,000 participants.Volunteers, aged 43 to 86, were then asked if they had regularly used aspirin at least twice a week for more than three months. The average duration of follow-up was 14.8 years.Researchers measured the incidences of different types of AMD. Wet AMD makes up just 10 per cent of cases but causes severe vision loss, while dry AMD is more common and milder - although it can develop into wet AMD at any time.
