摘要:

目的：探讨不同方法测量AC/A值所得结果是否相同以及产生这些不同的原因。方法：随机选取57名在校大学生，使用电脑验光仪和综合验光仪进行规范验光后，分别用隐斜法、梯度法、同视机法测量AC/A值。结果：梯度法和隐斜法测得的结果有统计学差异(P<0.01)，但和同视机法测得的结果无统计学差异(P>0.05)。梯度法中附加不同镜片所得的结果有统计学差异(P<0.05)，隐斜法中近方注视不同距离视标所得结果有统计学差异(P<0.01)，同视机法中附加不同镜片所得结果无统计学差异(P>0.05)。结论：梯度法中附加正镜片受到其他因素的影响较小。临床上测量AC/A值时应根据具体情况选择合适的方法并与该方法的正常范围进行比较。

Abstract:

Objective: To explore the AC/A ratio of using different methods are the same or not.Methods: AC/A ratios of 57 subjects were measured by Phoria method，Gradient method and Synoptophore method after refractively corrected by computer refractor and phoropter. Results: Statistically significant difference was observed between the ratios by Gradient method and Phoria method(P<0.01),but no difference between the ratios by Gradient method and Synoptophore method(P>0.05).And differences among the AC/A ratios measured by Gradient method with four different additions were observed(P<0.05).Difference was observed at different near stare distances by the Phoria method(P<0.05).No differences among the AC/A ratios measured by Synoptophore method with three different additions(P>0.05).Conclution: The AC/A ratio measured by Gradient method with additions may be less influenced. An appropriate method should be selected to measure AC/A ratio in clinical examination and compared with the normal range by the same measurement.
