使用睫状肌麻痹剂，对113名婴儿的屈光不正的变化进行了随访，在出生后的第一年内每隔3个月进行一次。等效球镜度的散点图显示，屈光度差异在26周和36周之间表现出-0.38 ds的显著近视移位，在36周和52周之间表现出-0.38 ds的显著近视移位。屈光差异的范围（95% CI）似乎与屈光不正的程度无关，并随时间推移而减少。到12个月龄时，等效球镜的频率分布似乎变得像成人一样呈尖峰形。平均散光度较低（小于1屈光度柱镜），且符合规则。屈光参差少见。这项纵向研究的结果指出了筛查的最佳时间，并可能在9至12个月大的年龄段为“异常”屈光不正开处方。
Using cycloplegia, the change in ametropia of 113 infants was followed at 3 month intervals over the first year of life. Scatterplots of the spherical equivalent power show that the dioptric differences exhibit a significant myopic shift of -0.38 ds between 26 and 36 weeks and -0.38 ds between 36 and 52 weeks. The spread of the dioptric differences (95% CI) does not appear to be related to the magnitude of the ametropia present and decreases with time. By 12 months of age the frequency distribution of the spherical equivalent appears to become leptokurtic as it is in the adult. On average the astigmatism was of low degree (less than 1 dioptre cylinder) and with the rule. Anisometropia was rarely seen. The results of this longitudinal study point to an optimal time for screening and perhaps prescribing for 'abnormal' refractive error between 9 and 12 months of age.
