The prevalence of age-related maculopathy (ARM) varies considerably in different locations and racial/ethnic groups around the world. At present there are insufficient data to determine whether it is likely that these differences in prevalence, especially for the early forms of ARM are due to variations in genetic and environmental factors or due to variations in age of the cohorts and methods used to ascertain and define ARM. In three population-based studies of whites living in Beaver Dam, Wisconsin, Blue Mountains, Australia, and Rotterdam, The Netherlands, in which similar methods of ascertainment and classification were used to detect and define ARM, late ARM was present in 1.2%, 1.4%, and 1.2% of the population less than 86 years of age, respectively. While data from clinical studies suggest that late ARM associated with choroidal neovascularization is rare in blacks compared with whites, some epidemiological studies suggest that late ARM may be similar in blacks and whites. There are still too few data from various ethnic/racial groups around the world and too few population-based data in older Hispanic and Asian populations to make meaningful comparisons. There is a need for further research into the distribution of ARM and its possible causes using similar methodologies to ascertain and define the disease. Further insights will be gained when genotypes associated with ARM are discovered.
