To compare and repeatedly measure cycloplegic refraction in a cross-section of children using retinoscopy and automated refraction.
A total of 560 children (corresponding to 1120 eyes) ranging in age from 3 to 10 years participated in the study. Each child underwent a comprehensive eye examination, which included table mounted autorefractor evaluation (Kowa KW-2000) and streak retinoscopy, both after cycloplegia with 1% cyclopentolate hydrochloride. Data were analyzed using Fourier decomposition of the power profile.
More positive values of M component and sphere value were given by cycloplegic autorefraction (AKW) compared with cycloplegic streak retinoscopy (RR). More negative values for the J45 vector and more positive for J0 were given AKW although this difference was not statistically significant.
Our study shows that the table mounted autorefkeratometer Kowa KW- 2000 can be applied to young children with cycloplegia as instrument for cycloplegic refraction, and a discount of +0.67 should be applied on the sphere value. Similar care should be taken on the evaluation of the sphere and spherical equivalent values should be applied in other devices.
使用检影验光法和自动验光法对儿童横断面的睫状肌麻痹验光结果进行比较和重复测量。
共有560名年龄在3至10岁之间的儿童（相当于1120只眼睛）参与了该研究。每个儿童在使用1%盐酸环喷托酯进行睫状肌麻痹后，都接受了全面的眼部检查，包括台式自动验光仪评估（拓普康KW-2000）和带状检影验光。使用功率分布的傅里叶分解对数据进行分析。
与睫状肌麻痹带状检影验光（RR）相比，睫状肌麻痹自动验光（AKW）得出的M分量和球镜值的正值更大。AKW得出的J45矢量值更负，J0值更正，尽管这种差异没有统计学意义。
我们的研究表明，台式自动验光仪拓普康KW-2000可作为睫状肌麻痹验光的仪器应用于患有睫状肌麻痹的幼儿，并且球镜值应减去+0.67。在评估球镜时应采取类似的谨慎措施，并且在其他设备中应应用等效球镜值。
