Abstract

Purpose: Although aspirin therapy is used widely in older adults for prevention of cardiovasculardisease, its impact on the incidence, progression and severity of age-related macular degeneration(AMD) is uncertain. The effect of low-dose aspirin on the course of AMD will be evaluated in thisclinical trial.Design: A sub-study of the ‘ASPirin in Reducing Events in the Elderly’ (ASPREE) trial, ASPREE-AMD is a5-year follow-up double-blind, placebo-controlled, randomized trial of the effect of 100 mg daily aspirinon the course of AMD in 5000 subjects aged 70 years or older, with normal cognitive function andwithout cardiovascular disease at baseline. Non-mydriatic fundus photography will be performed atbaseline, 3-year and 5-year follow-up to determine AMD status.Primary outcome measures: The incidence and progression of AMD. Exploratory analyses will determinewhether aspirin affects the risk of retinal hemorrhage in late AMD, and whether other factors,such as genotype, systemic disease, inflammatory biomarkers, influence the effect of aspirin on AMD.Conclusion: The study findings will be of significant clinical and public interest due to a potential toidentify a possible low cost therapy for preventing AMD worldwide and to determine risk/benefitbalance of the aspirin usage by the AMD-affected elderly. The ASPREE-AMD study provides a uniqueopportunity to determine the effect of aspirin on AMD incidence and progression, by adding retinalimaging to an ongoing, large-scale primary prevention randomized clinical trial.
