Two thousand nine hundred fourteen Chinese children (1510 males and 1404 females) were examined for the presence of scleral melanocytosis (SM) and oculodermal melanocytosis in a cross-sectional prevalence survey. SM was found in 4.9% of boys and 4.1% of girls under the age of 1 year. The peak prevalence was at 6 years of age, when 44.6% of boys and 46.6% of girls were affected. At 18 years of age, only 11.1% of boys and 13.2% of girls had SM. The overall prevalence, regardless of age, was 27.6% in boys and 27. 1% in girls. The condition was bilateral in 78% of cases. The medial superior quadrant was the most frequently affected site, and the lateral inferior quadrant was the least frequently affected site. Oculodermal melanocytosis occurred only in one patient; the pigmentation affected the left side of the face and the ipsilateral sclera.
在一项横断面患病率调查中，对2914名中国儿童（1510名男性和1404名女性）进行了巩膜黑素沉着症（SM）和眼皮肤黑素沉着症检查。在1岁以下的男孩中，SM的检出率为4.9%，女孩为4.1%。患病率高峰出现在6岁时，此时44.6%的男孩和46.6%的女孩患病。18岁时，只有11.1%的男孩和13.2%的女孩患有SM。无论年龄大小，男孩的总体患病率为27.6%，女孩为27.1%。78%的病例为双侧患病。上内侧象限是最常受累的部位，下外侧象限是最不常受累的部位。眼皮肤黑素沉着症仅发生在1例患者中；色素沉着累及面部左侧和同侧巩膜。
