摘要
目的了解镇江市城区学龄前儿童(3～6岁)的屈光状态,探讨视力随访与转诊标准。方法随机选择镇江市区3～6岁儿童6 236例(12 472眼)进行自然状态下屈光筛查及远视力检查,对各年龄组屈光偏离率、视力发育状况进行统计分析。结果屈光筛查总偏离率为25.64%,3、4、5、6岁组偏离率分别为22.84%、23.13%、27.60%、31.24%(χ2=68.399,P<0.01);远视力均值随年龄增长呈上升趋势,视力百分位数P5、P25、P50在3、4、5、6岁组分别为4.6、4.7、4.8,4.7、4.8、4.9,4.8、4.9、4.9,4.8、4.9、5.0。各年龄组屈光偏离儿童视力均数明显低于屈光正常儿童(P<0.01)。结论 3～6岁儿童随年龄增长,屈光偏离率呈上升趋势,视力发育水平不断完善,应定期进行屈光筛查及视力检查,以期早期发现弱视。
Objective To understand the refractive status of the preschool children aged 3-6 years old in the urban area of Zhenjiang city to explore the standards of visual acuity follow-up and transfer treatment. Methods 6 236 children aged 3-6 years old （12 472 eyes） in the urban area of Zhenjiang city were randomly selected and performed the refraction screening and distant visual acuity examination in the natural state. The rates of refractive deviation and the visual acuity development status among various age groups were statistically analyzed. Results The total rate of refractive deviation was 25.64% ,which in 3,4, 5,6 years old groups were 22.84%, 23.13%, 27.60% and 31.24% respectively（P〈0.01 ）. The mean values of distant visual acu- ity showed the increasing trend with the age increasing. The percentiles of visual acuity at PS, P25 and PS0 were 4.6,4.7,4.8 in 3 years old group,4.7,4.8,4.9 in 4 years old group,4.8,4.9,4.9 in 5 years old group and 4.8,4.9,5.0 in 6 years old group. The mean values of visual acuity in the various age groups with abnormal refraction were lower than those in the children with normal refraction（P〈0.01 ）. Conclusion The rate of refractive deviation in children aged 3-6 years old shows the increasing trend with the age increasing. The development of visual acuity is continuously perfected. It is necessary to conduct the refraction screening and visual acuity examination regularly in order to discover amblyopia early.
