| 摘 要： | 目的研究学龄儿童中屈光正常与低度近视者之间调节性集合（accommodative convergence，AC）与调节（acconunodation，A）比值的变化，初步探讨低度近视与调节性集合之间的关系。方法选择矫正视力正常及散瞳后屈光度在＋0．75D--1．25D之间的8～12岁学龄儿童63例，用同视机检测其AC／A值，两组AC／A值差异采用t检验。结果屈光度在＋0．75D--0．25D～-1．25D学龄儿童的AC／A值分别为4.1±0．84和2．7±0．63，两者差异有统计学意义。结论近视初期的学龄儿童AC／A值低于同龄儿童屈光正常者的AC／A值，在防治低度近视和视疲劳的同时，注意检查AC／A值的变化。

| Abstract: | Objective To explore the correlation between low myopia and accommodative convergence（AC） in school-age children. Methods The AC/A ratio was measured by a Synoptophore in 63 pupils aging from 8 to 12 years. Result The AC/A ratio had obvious differences between the refractive normal group and the low myopia group. Conclusion The AC/A ratio is lower in refractive normal pupils than in low myopia pupils. |
