Study Confirms Diabetics Of African Descent At Greater Risk For Cataracts SAN FRANCISCO, CA -- Feb. 3, 1999 -- Results of a study in the January 1999 issue of the journal Ophthalmology, suggest controlling diabetes, especially in people under the age of 60, may significantly reduce cataracts in people of African descent. M. Christina Leske, M.D. and colleagues from the University of New York Stony Brook conducted the Barbados Eye Study (BES), the largest study in the world to examine the prevalence, incidence and risk factors for major eye diseases in a population of African descent. In the BES, persons of African heritage were four times more likely to have cortical or spoke-like cataracts than Caucasians. Study authors looked at the relationship between risk factors such as diabetes, high blood pressure and obesity to explain the increased prevalence of cataracts in people of African ancestry. The authors found 14 percent of all cataracts studied could be attributed to diabetes. Diabetes was highly associated with cortical cataracts, especially among people under the age of 60. The study also found cortical cataracts related to central obesity and high blood pressure, which may be due to common underlying link with diabetes. "Given the increased prevalence of tons opacities in black populations, it is important to identify potentially modifiable factors that may lead to cataract prevention, especially at younger ages," they write, adding careful maintenance of diabetes may reduce this risk.
