儿童屈光状态随年龄的增长而变化。为了解屈光不正儿童屈光度的变化特点,我们对321例(共642眼)视力不良儿童作了连续观察(2～5年),现将结果报告于后。材料和方法本组321例,年龄2—14岁,平均6.8岁男177例,女144例。所有病例均排除其他器质性眼病,采用睫状肌麻痹检影法验光,每年一次,连续2—5年,将逐年屈光度及矫 Refractive status of children changes with age. In order to understand the changing features of refractive error in children, 321 cases (642 eyes) of visually impaired children were continuously observed (2-5 years), and the results are reported later. Materials and Methods The group of 321 cases, aged 2-14 years, an average of 6.8 years old male 177 cases, 144 females. All cases were excluded other organic eye disease, ciliary muscle paralysis retinoscopy retinoscopy, once a year for 2 to 5 years, the annual refraction and correction
