摘　　要：目的探讨错位验光法在检影验光中的应用,为准确验光提供有效措施。方法 3~12岁儿童67例(134眼),充分睫状肌麻痹,分别采用点状光常规柱镜检影验光法和点状光圆柱错位检影验光法,对两种检影验光方法散光轴位结果进行分析比较。结果点状光常规柱镜检影验光和点状光圆柱错位检影验光散光轴位误差比较,复『生近视散光组分别为3°、2°;复陛远视散光组分别为2°、1°,混合散光组分别为4°、2°,差异有统计学意义,P<0.05。结论在点状光柱镜检影中,圆柱错位检影验光法比常规柱镜检影验光法能够更精准的验证散光的度数和轴向。Objective To explore the application of dislocation optometry in retinoscopy and provide effective mea- sures for accurate optometry. Methods A total of 67 children （134 eyes） aged from 3 to 12 years with complete paralysis of the ciliary muscle were examined by point optics and spectroscopy. Axial of astigmatism results were analyzed and com pared. Results Axial of astigmatism obtained by conventional point light cylindrical retinoscopy refractometry and the cylindrical dislocation retinoseopy were 3° and 2° in complex myopic astigmatism group, 2 °, 1° in complex hyperopic astigmatism group, and 4°, 2° in mixed astigmatism group respectively. The difference was significant, P 〈0.05. Conclusions The cylindrical dislocation retinoscopy is more accurate than the conventional cylinder optometry to verify the degree and axial direction of astigmatism.
