本文研究了299名1 - 4岁散光患儿在发育过程中散光的变化。选择所有在眼科筛查调查中发现的至少一只眼睛散光1.0 D或以上的连续1岁婴儿进行随访。每隔一年纵向随访一次睫状体麻痹性屈光。在发育过程中，远视程度没有减少，但在测试期间，散光的发生率和数量明显减少。散光的程度和发生率最显著的下降发生在出生后的第一年和第二年。大多数1岁婴儿散光眼的水平曲率大于垂直曲率（加上圆柱轴180度），此后数年散光轴未发生变化。
Changes in astigmatism during development were studied in 299 infants with astigmatism as they grew from 1 to 4 years of age. All consecutive cases of 1-year-old infants with an astigmatism of 1.0 D or more in at least one eye found at an ophthalmic screening survey were selected for follow-up. The cycloplegic refraction was longitudinally followed at yearly intervals. During development there was no decrease in the degree of hypermetropia, but there was a significant decrease in the incidence and amount of astigmatism during the test period. The most pronounced decrease in magnitude and incidence of astigmatism occurred between the first and second year of life. The majority of astigmatic eyes of the 1-year-old infants had a horizontal curvature greater than the vertical (plus cylinder axis of 180.degree.), and no changes of the axis of the astigmatism were noted during the following years.
