Human anisometropia and changes in it were followed over a 3-year period in 238 schoolchildren who had uncomplicated school myopia in both eyes. Anisometropia of the spherical equivalent (ASFE) type increased in 27%, decreased in 6%, and remained unchanged in 67% of these children. When mean myopia increased from -1.43 to -3.06 D, mean ASFE increased from 0.30 to 0.51 D and the anisometropia of astigmatism (AAST) from 0.15 to 0.23 D. The faster the increase in myopia the greater was the increase in ASFE (r = 0.133, N = 238, p = 0.020). The higher the spherical equivalent at the end of the study the higher was the ASFE (r = 0.135, N = 238, p = 0.019). The initial refractive error or the amount or the axis of astigmatism did not have any prognostic value for the changes in ASFE. The higher the ASFE at the end of the study the higher also was the AAST (r = 0.136, N = 238, p = 0.018). The change in ASFE was independent of the wearing of spectacles. The distribution of the anisometropia of the spherical equivalent and its change followed a nearly normal distribution with the peak of eyes at about +/- 0 refraction.
对238名双眼患有单纯性学校性近视的学童进行了为期3年的随访，观察其双眼屈光参差及其变化情况。这些儿童中，等效球镜屈光参差（ASFE）型增加的占27%，减少的占6%，保持不变的占67%。当平均近视度数从-1.43D增加到-3.06D时，平均ASFE从0.30D增加到0.51D，散光性屈光参差（AAST）从0.15D增加到0.23D。近视增加越快，ASFE增加越大（r = 0.133，N = 238，p = 0.020）。研究结束时等效球镜度数越高，ASFE越高（r = 0.135，N = 238，p = 0.019）。初始屈光不正、散光量或散光轴对ASFE的变化均无预后价值。研究结束时ASFE越高，AAST也越高（r = 0.136，N = 238，p = 0.018）。ASFE的变化与是否佩戴眼镜无关。等效球镜屈光参差的分布及其变化近似正态分布，屈光为±0的眼睛数量最多。
