Abstract:AIM: To investigate the effect of accommodation on peripheral refraction in patients with myopia.
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.
