摘　　要：目的探讨正柱定轴正负柱镜检影法在混合散光检影中的优越性。方法随机选择96例(155眼)混合性散光患者进行正柱定轴正负柱镜检影(试验组80眼)与联合应用正负柱镜检影法检影(对照组75眼)。将散光分为3个区(<3.00D,3.00D～6.00D,>6.00D,根据中和影的形态,轴位准确度,检影时间与镜片组合综合评价检影效果。结果散光在3.00D以下者,试验组与对照组差异无显著性,3.00D～6.00D与大于6.00D,试验组与对照组差异有显著性。结论正柱定轴正负柱镜检影法较联合应用正负柱镜检影法对中高度混合散光是一种更为快捷和准确的检影方法。Objective To investigate the superiority of clinical retinoscopy with positive cylinders deciding axis and the plus or mins cylinders examinaing the reflection of the light in mixed astigmatism eyes. Methods 96 cases with mixed astigmatism were divided into three groups （〈3.00D, 3.00D-6.00D, 〉6.00D）. Retinoscopy of the positive cylinders deciding axis and the plus or minus cylinders were applied in 80 eyes, while retinoscopy of combined positive cylinder with negative cylinders was used in 75 eyes as match control. According to the shape of neutralized image, the accuracy and facility of the axis judgement, operating time and combined lens were comprehensively evaluated. Results In the group of mixed astigmatism less than 3.00d no significant defference was found between the experiment group and the controll group. In the group of mixed astigmatism 3.00D-6.00D, significant difference was found between the two groups. Conclusion In higher degree of mixed astigmatism the retinoscopy of positive cylinders deciding axis and the plus or minus cylinders examinating the reflection of the light is a kind of more convenient and precise method.
