目的：探讨调节对近视患者视网膜周边离焦量的影响。

方法：横断面研究。纳入近视患者105例105眼，将患者根据其近视程度分为3组：高度组(SE≤-6.00 D)、中度组(-6.00 D结果：患者105例105眼中男48例，女57例，平均年龄13.6±1.6岁。三组患者一般资料具有可比性。睫状肌麻痹前后的视网膜周边离焦量比较：除RDV-15°无明显改变之外，其余参数值均出现远视性漂移。在睫状肌麻痹后，RDV-15°、RDV-30°、RDV-45°表现为越偏离黄斑中心凹、差距越大。低、中、高度组的变化量比较：三组间ΔTRDV、ΔRDV-45°、ΔRDV-I、ΔRDV-N比较均有差异，低度、中度近视的变化量大于高度近视的变化量(均P<0.017)，低度组与中度组的变化量无差异(均P>0.017)。

结论：调节可影响近视患者视网膜周边离焦量，对中低度近视的影响大于高度近视。

METHODS: Cross-sectional study. A total of 105 patients(105 eyes)with myopia were consecutively recruited in this study. According to the degree of myopia, patients were divided into high myopia(SE≤-6.00 D), moderate myopia(-6.00 DRESULTS: There were 48 males and 57 females, with a mean age of 13.6±1.6 years old. The general data of the three groups were comparable. RDV-15° remained stable, whereas other parameters shifted significantly toward hyperopia. After cycloplegia, the RDV-15°, RDV-30° and RDV-45° showed larger differences when deviated from macular fovea. There were differences among the three groups in ΔTRDV, ΔRDV-45°, ΔRDV-I and ΔRDV-N, and the change of the low and moderate myopia groups was larger than that of the high myopia group(all P<0.017), whereas low and moderate myopic eyes did not differ significantly from each other(all P>0.017).

CONCLUSION: The accommodation can affect the peripheral defocus in myopic patients, and the effect on moderate and low myopia is greater than that of high myopia.
