目的:探讨散瞳前后不同屈光状况下电脑验光屈光度的关系。方法:选择应用盐酸环喷托酯散瞳样本322例(644眼),采集其散瞳前后电脑自动验光结果,按照散瞳后屈光度分为远视组、正视组和近视组,建立散瞳前后屈光度的回归模型。结果:不同年龄组散瞳前后屈光度差异显著(P<0.01);按照不同年龄组分别进行回归分析,各年龄组拟合方程的决定系数均在0.93以上;而远视组和正视组回归方程的决定系数较低。结论:近视组散瞳前后屈光度均呈现显著线性相关。
Objective: To investigate the relationship between computer optometry refraction under different refractive conditions before and after mydriasis. Methods: 322 cases (644 eyes) of cyclosporic acid ester mydriasis were selected and collected before and after mydriasis, and were divided into hyperopia group, orthophoria group and myopia group according to diopter after dilation, and the diopter before and after diopter Regression model. Results: There were significant differences in diopter before and after dilation in different age groups (P <0.01). According to the regression analysis of different age groups, the coefficient of determination for the fitting equation of each age group was above 0.93. The regression equations of hyperopia group and orthophoria group were determined The coefficient is lower. Conclusion: There is a significant linear correlation between diopter before and after dilation in myopia.
