Features of age-related macular degeneration in a black population
Abstract
OBJECTIVE: To report on the frequency of features of age-related macular degeneration in a black population based on fundus photograph gradings. DESIGN: Population-based study. SETTING: Barbados, West Indies. STUDY POPULATION: Residents of Barbados, selected by a random sample of Barbados-born citizens, aged 40 to 84 years. MAIN OUTCOME MEASURE: Gradings from 30 degrees stereoscopic macular photographs. RESULTS: Black participants (n = 3444) completed examinations at the study site and had gradable macular photographs in both eyes. Drusen larger than 63 microns occurred with comparable frequency in men and women. The frequency of small drusen decreased with age, while medium and large drusen were more common in older participants. Frequencies of all age-related macular degeneration-related characteristics were similar for men and women except for small drusen, which occurred more commonly in women. Confluent drusen and pigment atrophy also increased significantly with age. Exudative features occurred in 0.5% of the participants. CONCLUSIONS: This study provides population-based data on the frequency of features of age-related macular degeneration based on photographic gradings of a black population. Features of early age-related macular degeneration were common, but appeared at a lower frequency than has been reported for white populations. Exudative disease was infrequent, occurring in about one of 200 participants.

Drusen are seen at similar frequencies in white and non-white individuals.
“Data from the Barbados Eye Study,42 the Baltimore Eye Study,25 the Age-Related Eye Disease Study (AREDS),28 and the National Health and Nutrition Examination Survey III (NHANES III)41 have shown that drusen are seen at similar frequencies in white and non-white individuals.”

There is a definite increased prevalence of advanced age-related macular degeneration in white people compared with others.
“However, these studies also show a definite increased prevalence of advanced age-related macular degeneration in white people compared with others.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
