2803名学龄前儿童视力的筛查分析

Analysis of vision screening of 2803 preschool children

目的：了解我市开发区幼儿园学龄前儿童的视力状况，以便更好地开展儿童视力保健服务。方法用国产MOPTIM手持自动验光仪对开发区幼儿园2803名3～6岁儿童视力筛查，并对数据进行统计分析。结果2803名学龄前儿童屈光异常检出率为7.28%（204/2803），男、女童屈光异常检出率分别为6.76%（102/1508）和7.88%（102/1295），差异无统计学意义（χ2=1.10，P〉0.05）。3～〈4、4～〈5、5～〈6、6～〈7岁各年龄组屈光异常检出率分别为6.95%（39/561）、7.01%（61/870）、7.42%（67/903）、7.89%（37/469），差异无统计学意义（χ2=0.47，P＆gt;0.05）。儿童屈光状态以散视最多，占61.3%（125/204），其次为远视，占36.3%（74/204），近视最少，占2.5%（5/204），差异有统计学意义（χ2=201.4，P〈0.01）。结论学龄前儿童屈光异常状态不容忽视，视力筛查仪检测方便、实用，适合在学龄前儿童视力筛查中使用。

Objective To understand preschool children’s visual acuity in development area of our city,for further im-proving children’s eye health care. Methods 2803 kindergarten children,age from 3 to 6 years,were selected and their vision was screened with handheld refractometer （MOPTIM,made in China）.Then statistical analysis of data was given. Results The refractive abnormal rate was 7.28%（204/2803） in kindergarten children.The abnormal rate in boys and girls were 6.76%（102/1508） and 7.88% （102/1295） respectively,and the difference had no statistically significant （χ2=1.10,P＆gt;0.05）.The abnormal rate in age group of 3-〈4,4-〈5,5-〈6,6-〈7 years were 6.95% （39/561）,7.01% （61/870）, 7.42% （67/903）,7.89% （37/469） respectively,and the difference had no statistically significant （χ2=0.47,P〉0.05）.Refrac-tive status of children with abnormal vision was mainly blanking,occupying 61.3% （125/204）;followed by hyperopia,oc-cupying 36.3% （74/204）;myopia at least,occupying 2.5% （5/204）,and the difference was statistically significant （χ2=201.4,P〈0.01）. Conclusion Refractive status of preschool children with abnormal vision should not be ignored,and vi-sion screening instrument is suitable for preschool children as its advantages in convenience and functional.
