  1. The Prevalence of age-related Maculopathy by geographic region and ethnicity : The Colorado-Wisconsin study of age-related maculopathy.

    Article - En anglais


    To determine the prevalence of age-related maculopathy (ARM) in a biethnic population and to determine if there are ethnic and/or geographic differences in the prevalence of ARM.


    Prevalence data from 2 population-based studies, the San Luis Valley Diabetes Study (n=1541, ages 21-74 years) and the Beaver Dam Eye Study (n=3999, ages 43-74 years), were compared.


    Southern Colorado and central Wisconsin.

    Main Outcome Measure 

    Color stereoscopic fundus photographs were graded for ARM using the Wisconsin Age-related Maculopathy Grading System.

    Similar questionnaire, laboratory, and clinical data on potential risk factors were available from both studies.


    Late-stage ARM was significantly less frequent among Hispanics than non-Hispanic whites (NHW) in Beaver Dam (odds ratio [OR]=0.07 ; 95% confidence interval [CI]=0.01-0.49 ; Hispanics vs Beaver Dam NHW).

    The prevalence of any ARM was significantly lower among San Luis Valley NHW (10.4%) than Beaver Dam NHW (14.3%) (OR=0.67 ; 95% Cl=0.50-0.91).

    This prevalence difference was not explained by any of the risk factors examined (smoking, cardiovascular disease, diabetes, alcohol consumption, etc).

    The 2 NHW groups reported different European heritages.


    Late-stage ARM appeared to be rare among Hispanics but there was no ethnic difference in prevalence of any ARM. (...)
