Abstract

PURPOSE

To compare pre- and postcycloplegic autorefraction in two separate age samples of Australian school children.

DESIGN

Population-based cross-sectional study of random cluster samples.

METHODS

Autorefraction was performed before and after cycloplegia, using 1% cyclopentolate, in the right eyes of 2,233 12-year-old and 210 6-year-old children.

RESULTS

The mean spherical equivalent (SEQ) difference between these measures was 0.84 diopters (D) (95% confidence interval (CI) 0.81 to 0.87 D), more hyperopic in post- than precycloplegic autorefractive assessments in the 12-year-old children and 1.18 D (95% CI 1.05 to 1.30 D) more hyperopic in the 6-year-old children. Precycloplegic autorefraction substantially overestimated the proportion of children with myopia, misclassifying 17.8% aged 12 years and 9.5% aged 6 years. Conversely, precycloplegic autorefraction did not detect moderate to high hyperopia in 2.28% of 12-year-olds and 17.14% of 6-year-olds.

CONCLUSIONS

Our findings reinforce the importance of using cycloplegic autorefraction in children up to age 12 years.

摘要

目的

比较澳大利亚学龄儿童两个不同年龄样本在使用睫状肌麻痹剂前后的自动验光结果。

设计

基于人群的随机整群抽样横断面研究。

方法

对2233名12岁儿童和210名6岁儿童的右眼，使用1%环喷托酯进行睫状肌麻痹前后的自动验光。

结果

这些测量结果之间的平均等效球镜度（SEQ）差异为0.84屈光度（D）（95%置信区间（CI）0.81至0.87 D），在12岁儿童中，睫状肌麻痹后自动验光评估比麻痹前更远视，在6岁儿童中则多1.18 D（95% CI 1.05至1.30 D）。睫状肌麻痹前的自动验光显著高估了近视儿童的比例，12岁儿童中有17.8%被误分类，6岁儿童中有9.5%被误分类。相反，睫状肌麻痹前的自动验光未检测出12岁儿童中2.28%和6岁儿童中17.14%的中度至高度远视。
