带状光检影镜在学龄前儿童屈光筛查中的应用

Application of the Ribbon-Shaped Light Retinoscope in Refractive Screening for Preschool Children

目的:分析带状光检影镜在学龄前儿童屈光筛查中的应用价值。方法:选择2022年6月~2024年6月来本院接受屈光筛查的1753例学龄前儿童,分别提供带状光检影镜检查、国际标准视力表检查,对初筛屈光异常者提供电脑验光检查并作为金标准,分析带状光检影镜结果。结果:国际标准视力表检出异常例数78例,带状光检影镜检出80例,电脑验光检出80例,三组检出情况对比无统计学意义(χ2=0.029,P=0.986);学龄前3岁儿童的屈光异常检出率为4.75%,远视、近视、远视散光及混合散光检出率分别为1.43%、2.38%、0.47%和0.47%,学龄前4岁儿童的屈光异常检出率为3.68%,远视、近视、远视散光及混合散光检出率分别为1.15%、1.84%、1.15%和0.23%,学龄前5岁儿童的屈光异常检出率为4.44%,远视、近视、远视散光及混合散光检出率分别为1.33%、2.44%、0.22%和0.44%,学龄前6岁儿童的屈光异常检出率为5.37%,远视、近视、远视散光及混合散光检出率分别为0.90%、3.36%、0.67%和0.22%,对比差异无统计学意义(P>0.05)。结论:带状光检影镜应用于学龄前儿童屈光筛查中,对远视、近视、远视散光及混合散光均具有良好的筛查价值。

Objective:To analyze the application value of the strip-shaped light retinoscope in refractive screening for preschool children.Methods:1753 preschool children who came to our hospital for refractive screening from June 2022 to June 2024 were selected.They were provided with a ribbon-shaped light retinoscope and an international standard visual acuity chart for examination,and those with abnormal refractive error were provided with a computer optometry examination.The results of the ribbon-shaped light retinoscope were analyzed.Results:The number of abnormal cases detected by the international standard visual acuity chart was 78,the number of cases detected by the ribbon light retinoscope was 80,and the number of cases detected by computer optometry was 80,with no statistically significant difference(χ2=0.029,P=0.986).The detection rate of refractive abnormalities in preschool children aged 3 years was 4.75%,with the detection rates of hyperopia,myopia,hyperopic astigmatism,and mixed astigmatism being 1.43%,2.38%,0.47%,and 0.47%,respectively.The detection rate of refractive abnormalities in preschool children aged 4 years was 3.68%,with the detection rates of hyperopia,myopia,hyperopic astigmatism,and mixed astigmatism being 1.15%,1.84%,1.15%,and 0.23%,respectively.The detection rate of refractive abnormalities in preschool children aged 5 years was 4.44%,with the detection rates of hyperopia,myopia,hyperopic astigmatism,and mixed astigmatism being 1.33%,2.44%,0.22%,and 0.44%,respectively.The detection rate of refractive abnormalities in preschool children aged 6 years was 5.37%,with the detection rates of hyperopia,myopia,hyperopic astigmatism,and mixed astigmatism being 0.90%,3.36%,0.67%,and 0.22%,respectively.There was no statistically significant difference(P>0.05)between the comparison groups.Conclusion:The application of the band-shaped light retinoscope in preschool children’s refractive screening has good screening value for hyperopia,myopia,hyperopic astigmatism,and mixed astigmatism.
