MADISON, Wisc. — A higher prevalence of early age-related maculopathy was found in whites than in blacks in a population-based study in four U.S. counties.

Ronald Klein, MD, and colleagues examined a biracial population comprised of 1,998 whites and 363 blacks, ranging in age from 69 to 97 years, to determine the prevalence of early age-related maculopathy (ARM) and its relation to cardiovascular disease risk factors and outcomes.

Early ARM was present in 15.5% of the cohort, and late ARM in 1.3%. Overall prevalence of any ARM was lower in blacks (9.1%) than in whites (18.2%).

Although an association was found between signs of white matter disease and early ARM, there was no evidence of an association of ARM with either hypertension or inflammatory factors.

The study is published in the January issue of Ophthalmology.
