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(ac-commodation,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。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.
