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 degrees), and no changes of the axis of the astigmatism were noted during the following years.
对299例散光婴儿从1岁到4岁成长过程中散光的变化进行了研究。在一次眼科筛查中发现的所有至少一只眼睛散光1.0 D或更高的1岁婴儿连续病例均被选入随访。每年对睫状肌麻痹验光进行纵向随访。在发育过程中，远视度数没有降低，但在测试期间散光的发生率和度数有显著降低。散光度数和发生率最明显的降低发生在生命的第一年和第二年之间。1岁婴儿的大多数散光眼水平曲率大于垂直曲率（正柱镜轴为180度），在接下来的几年中未观察到散光轴的变化。
