Data for analysis of age-related changes in growth in the intercanthal (en-en) and biocular (ex-ex) widths were obtained from 1,594 healthy North American Caucasians in age groups from 1 to 18 years, divided equally between males and females. At 1 year, the degree of development of the intercanthal width reached 84.1%, and that of the biocular width 85.9% of adults in both sexes. The levels of growth achieved by 5 years of age rose to 93.3% in the intercanthal width and 88.1% in the biocular width, in both sexes. The average total growth increments achieved between ages 1 and 18 years were 5.2 mm in the intercanthal width and 12.5 mm in the biocular. The intercanthal width showed very little growth after 1 year of age; in contrast, the biocular width showed significantly greater growth increments both before and after 5 years of age. Rapid growth was observed between 3 and 4 years in the intercanthal width of both sexes. The age-related growth observed in the biocular width was small but continuous up to maturation time. The intercanthal width reached full maturation at 8 years in females and 11 years in males, and the biocular width at 13 years in females and 15 years in males.
用于分析内眦（en-en）和双眼（ex-ex）宽度随年龄增长变化的数据，来自1594名年龄在1至18岁之间的健康北美白种人，男女各半。1岁时，男女内眦宽度的发育程度达到成年人的84.1%，双眼宽度达到85.9%。到5岁时，男女内眦宽度的生长水平升至93.3%，双眼宽度升至88.1%。1至18岁期间，内眦宽度的平均总生长增量为5.2毫米，双眼宽度为12.5毫米。1岁以后，内眦宽度几乎没有增长；相比之下，5岁前后双眼宽度的生长增量明显更大。男女内眦宽度在3至4岁之间均出现快速增长。双眼宽度随年龄增长的变化较小，但一直持续到成熟阶段。女性内眦宽度在8岁时完全成熟，男性在11岁时完全成熟；女性双眼宽度在13岁时完全成熟，男性在15岁时完全成熟。
