Consecutive screenings by the same examiner (the author) disclosed among 380 white North Europeans (Copenhagen, Denmark) pigmentation of the plica semilunaris and/or lacrymal caruncle in 2%, among 189 Mongols (Kyoto, Japan) in 4%, and among 257 Eskimos (East Greenland) in 45% (P less than 0.001). In Eskimos the phenomenon was found to be bilateral in 60% and confluent with pigmentation of the bulbar conjunctiva in 18%. The prevalence is the highest among males, rising with increasing age. It is correlated to the prevalence of pigmentation of the bulbar conjunctiva, whereas not to that of subconjunctival pigmentation round scleral emissaries.
由同一位检查者（作者）进行的连续筛查发现，在380名北欧白人（丹麦哥本哈根）中，半月皱襞和/或泪阜色素沉着的发生率为2%；在189名蒙古人（日本京都）中为4%；在257名爱斯基摩人（东格陵兰）中为45%（P<0.001）。在爱斯基摩人中，60%的色素沉着现象为双侧性，18%与球结膜色素沉着融合。该现象在男性中最为常见，且随年龄增长而增加。它与球结膜色素沉着的发生率相关，而与巩膜导静脉周围结膜下色素沉着的发生率无关。
