目的/背景——在之前的一项研究中，研究了屈光参差的纵向变化。结果表明，屈光参差在正视化过程中出现和消失，并且弱视的相关风险很低。本研究的目的是纵向追踪 1 岁时患有明显屈光参差儿童的视力和屈光度。方法 - 每六个月对选定的 20 名 1 岁时明显屈光参差大于或等于 3.0 D（球镜当量）的儿童（约 3 至 10 岁）儿童组进行屈光不正和视力评估。结果 - 这些儿童可分为三组。六名受试者的屈光参差增加（平均 1.4 D），并且他们都出现了弱视。剩下的孩子可以分为大小相等的两组。一组没有出现弱视，屈光参差平均下降了 3.0 D。其余 7 名儿童出现了弱视和/或斜视；平均屈光参差减少量为 1.2 D。 结论：1 岁时屈光参差大于或等于 3.0 D 的病例在 10 岁时仍然存在，90%。该群体发生弱视的风险很大（60%）。
Aims/background-In a previous study longitudinal changes of anisometropia were investigated. It was shown that anisometropia arises and vanishes during the emmetropisation process and that the associated risk for amblyopia is low. The aim of this study was to follow acuity and refraction longitudinally in children with marked anisometropia at 1 year of age.Methods-Refractive errors and visual acuity were estimated every sixth month for a selected group of 20 children with marked anisometropia greater than or equal to 3.0 D (spherical equivalent) at 1 year of age from approximately 3 to 10 years of age.Results-The children could be classified into three groups. In six subjects the anisometropia increased (mean 1.4 D) and they all developed amblyopia. The remaining children could be classified into two groups of equal size. One group developed no amblyopia and the anisometropia decreased with a mean of 3.0 D. The seven remaining children developed amblyopia and/or strabismus; the mean anisometropia decrease was 1.2 D.Conclusion-Anisometropia at 1 year of age that is larger or equal to 3.0 D will in 90% of the cases still be there at 10 years of age. There is a substantial risk of this group developing amblyopia (60%).
