We studied groups of normal infants and infants with amblyopia and esoropia to determine the incidence of infantile astigmatism. Under cycloplegia, 19% of normal infants had astigmatism; this was at least twice the incidence in adults, but less than one-hale that found by noncycloplegic refractions of infants. During the first three postnatal years the incidence of astigmatism and distributions of spherical equivalents and anisometropia did not distinguish normal patients from most of those with esotropia and amblyopia.
我们研究了正常婴儿组以及患有弱视和内斜视的婴儿组，以确定婴儿散光的发病率。在睫状肌麻痹下，19%的正常婴儿有散光；这至少是成年人发病率的两倍，但不到对婴儿进行非睫状肌麻痹验光所发现发病率的一半。在出生后的头三年里，散光的发病率、等效球镜度和屈光参差的分布并不能区分正常患者与大多数患有内斜视和弱视的患者。
