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.
对189名各年龄段的蒙古族日本男女进行巩膜变性筛查，结果显示52%的人存在脂质沉积，尤其是在睫状前血管周围。这一患病率超过了丹麦的高加索人（N = 689）、格陵兰的爱斯基摩人（N = 340）和约旦的阿拉伯人（N = 127），所有这些人群均由同一名工作人员采用相同技术进行检查。巩膜斑（水平肌前方界限清晰的透明区）在日本人中的出现率不超过0.5%。这种现象在爱斯基摩人中同样罕见，但在高加索人中很常见。文中讨论了地域差异的原因。
