Thirty-two children who had been refracted in early infancy were re-refracted at the age of 7 to 8 years. Refraction comprised cycloplegic retinoscopy at the mean age of 11 weeks and noncycloplegic retinoscopy and subjective examination at the mean age of 94 months. The change in spherical equivalent refraction (SER) was highly negatively correlated with the initial refraction (-0.863), demonstrating emmetropization; however, the correlation between the refractive error at age 7 to 8 years and the refractive error in infancy was much weaker (+0.225). The SER was significantly less and the astigmatism was greater in infancy in children who were myopic at age 7 to 8 years. There was, however, extensive overlap in range between the SER for the two groups and the initial SER was not a good predictor of myopia at 7 to 8 years, although it may help to identify children who are unlikely to become myopic. One hyperopic child with bilateral ptosis failed to emmetropize.
32名在婴儿早期接受过验光的儿童在7至8岁时再次接受验光。验光包括在平均11周龄时进行睫状肌麻痹视网膜检影,以及在平均94月龄时进行非睫状肌麻痹视网膜检影和主观检查。等效球镜度(SER)的变化与初始验光结果呈高度负相关(-0.863),表明正视化;然而,7至8岁时的屈光不正与婴儿期屈光不正之间的相关性要弱得多(+0.225)。7至8岁近视的儿童在婴儿期的SER明显更低,散光更大。然而,两组的SER范围有广泛重叠,初始SER并不是7至8岁近视的良好预测指标,尽管它可能有助于识别不太可能近视的儿童。一名患有双侧上睑下垂的远视儿童未能实现正视化。
