Abstract

Aim: To compare the subjective refraction data with auto-refraction findings in high astigmatisms.

Methods: In a cross-sectional study, sampling was done from in different geographic regions in Iran using a multistage random cluster sampling method. All study participants underwent cycloplegic auto-refraction and subjective refraction using the red-green test.

Results: In this study, 277 eyes of 158 students aged 8 to 15y were analyzed. According to the results, the mean difference between subjective refraction and autorefraction in measuring sphere, cylinder, spherical equivalent, J0, and J45 was -0.18±0.76, -0.36±0.40, -0.36±0.79, 0.15±0.20, and 0.05±0.21 respectively. The correlation of these two refraction methods in measuring the aforementioned indices was 0.963, 0.898, 0.960, 0.931, and 0.948 respectively. The 95% limits of agreement of the two methods in measuring the above indices were -1.66 to 1.31, -1.14 to 0.42, -1.91 to 1.19, -0.24 to 0.54, and -0.36 to 0.47 respectively. The agreement between the two methods decreased with increasing cylinder power, and the best agreement was found in myopic individuals.

Conclusion: The measurements obtained by autorefractometer have a significantly higher cylinder average compared to subjective refraction. However, in the cylinder range of 4-5 diopters, the values of J0 and J45 do not have a high correlation.

高度散光中的自体屈光与主观屈光。

目的：比较高度散光患者的主观屈光资料与自动屈光资料。方法：在横断面研究中，采用多阶段随机聚类抽样方法，从伊朗不同地理区域进行抽样。所有的研究参与者使用红绿测试进行了睫状体麻痹性自动屈光和主观屈光。结果：本研究对158名8 ~ 15岁学生277只眼睛进行了分析。结果表明，测量球体、圆柱体、球体当量、J0和J45时，主观折射与自折射的平均差值分别为-0.18±0.76、-0.36±0.40、-0.36±0.79、0.15±0.20和0.05±0.21。两种折射法测量上述指标的相关系数分别为0.963、0.898、0.960、0.931和0.948。两种方法测定上述指标的95%一致性限分别为-1.66 ~ 1.31、-1.14 ~ 0.42、-1.91 ~ 1.19、-0.24 ~ 0.54、-0.36 ~ 0.47。两种方法的一致性随柱体功率的增加而降低，在近视个体中一致性最好。结论：自动屈光计测量的柱面平均值明显高于主观屈光计。而在4-5屈光度的柱面范围内，J0和J45的值相关性不高。
