Abstract

PURPOSE

We aimed to investigate whether the accuracy of the Plusoptix A09 photorefractor in children with ametropia is enhanced by cycloplegia with 1% tropicamide.

METHODS

A total of 70 eyes (70 children) were retrospectively reviewed. Noncycloplegic photorefraction, cycloplegia with 1% tropicamide, cycloplegic photorefraction, and cycloplegic refraction with a tabletop autorefractometer were performed on all subjects in this order. Measurements were compared statistically.

RESULTS

The mean age was 45.9 ± 11.4 months. The mean spherical equivalent (0.61 ± 1.03 diopters (D); range, -2.38 to 3.63 D) and mean spherical power (1.16 ± 0.92 D; range, -1.25 to 3.75 D) values that were acquired from the photorefraction without cycloplegia showed statistically significant differences from those of the autorefraction with cycloplegia (mean spherical equivalent = 1.00 ± 1.27 D; range, -1.50 to 4.25 D, mean spherical power = 1.60 ± 1.14; range, -1.25 to 4.50 D). The mean difference for the spherical equivalent was -0.39 ± 0.93 D (=0.021; 95% limits of agreement (LoA) = -2.22 D to 1.44 D) and for spherical power was -0.44 ± 1.02 D (=0.016; LoA = -2.44 D to 1.56 D). Without cycloplegia, Plusoptix A09 showed myopic shift, while after cycloplegia, it showed hyperopic shift. Spherical equivalent (mean difference (MD) ± SD = 0.78 ± 1.00 D, < 0.001; LoA = -1.17 D to 2.72 D) and spherical power (MD ± SD = 0.73 ± 1.04 D, < 0.001; LoA = -1.31 D to 2.77 D) values were significantly different from those of autorefraction with cycloplegia. Cylindrical power values obtained by photorefraction both with and without cycloplegia were not statistically different from those of autorefraction with cycloplegia ( > 0.05).

CONCLUSION

Cycloplegia with 1% tropicamide did not improve the accuracy of photorefraction using Plusoptix A09 in preschool children. The spherical equivalent and spherical power values obtained by photorefraction with cycloplegia were significantly higher from those obtained by autorefraction with cycloplegia.

摘要

目的

我们旨在研究使用1%托吡卡胺进行睫状肌麻痹是否能提高Plusoptix A09验光仪对屈光不正儿童验光的准确性。

方法

回顾性分析70只眼（70名儿童）。所有受试者均依次进行了非睫状肌麻痹验光、1%托吡卡胺睫状肌麻痹、睫状肌麻痹验光以及使用台式自动验光仪进行睫状肌麻痹验光。对测量结果进行统计学比较。

结果

平均年龄为45.9±11.4个月。非睫状肌麻痹验光获得的平均球镜等效度（0.61±1.03屈光度（D）；范围为-2.38至3.63 D）和平均球镜度数（1.16±0.92 D；范围为-1.25至3.75 D）与睫状肌麻痹自动验光结果相比差异有统计学意义（平均球镜等效度=1.00±1.27 D；范围为-1.50至4.25 D，平均球镜度数=1.60±1.14；范围为-1.25至4.50 D）。球镜等效度的平均差值为-0.39±0.93 D（=0.021；95%一致性界限（LoA）=-2.22 D至1.44 D），球镜度数的平均差值为-0.44±1.02 D（=0.016；LoA=-2.44 D至1.56 D）。未进行睫状肌麻痹时，Plusoptix A09显示近视偏移，而睫状肌麻痹后显示远视偏移。球镜等效度（平均差值（MD）±标准差=0.78±1.00 D，<0.001；LoA=-1.17 D至2.72 D）和球镜度数（MD±标准差=0.73±1.04 D，<0.001；LoA=-1.31 D至2.77 D）与睫状肌麻痹自动验光结果差异有统计学意义。睫状肌麻痹和未睫状肌麻痹验光获得的柱镜度数与睫状肌麻痹自动验光结果相比差异无统计学意义（>0.05）。
