Screening of 189 Mongolian Japanese of both sexes in all age groups for scleral degenerations revealed presence of lipid deposits, especially round the anterior ciliary vessels, in 52%. The prevalence exceeds that among Caucasians in Denmark (N = 689), Eskimos in Greenland (N = 340), and Arabs in Jordan (N = 127), all examined by the same worker employing the same technique. Scleral plaques (well‐defined transparency anterior to horizontal muscle) is present in no more than 0.5% of Japanese. This phenomenon is likewise rare among Eskimos, but frequent among Caucasians. The causes of the geographic differences are discussed.
