摘　　要：目的采用视动性眼球震颤原理和计算机图像识别及追踪识别技术自动检测18月~4岁儿童远视力,描绘不同年龄段幼儿的视力正常分布。方法于2023年5月至7月对江苏省妇幼保健院健康体检门诊的18月、24月、30月、3岁、4岁不同年龄组儿童,除常规儿童眼保健检查外,使用自动OKN视力检测仪检查单眼远视力。分析不同年龄段儿童的视力可测率及正常儿童的OKN视力分布值。结果共有655名儿童接受检查,包括339名男童和316名女童,整体可测率82.14%。不同年龄组间可测率差异存在统计学意义,随年龄提高而升高(χ2=12.551,P=0.014)。排除异常人群后,485名正常参考人群的右眼OKN视力在18月组、24月组、30月组的80%界值均为4.3,各组间两两比较无统计学意义(P=0.260,P=0.990)。OKN视力在3岁组的80%界值为4.5,4岁组为4.6,组间差异具有统计学意义(P<0.001)。结论自动OKN视力检查法在18月~4岁儿童中的可测率较高,幼儿不同阶段的正常视力值在评估幼儿视觉发育和判断眼病对视力损伤等方面具有重要应用价值。Objective This study aimed to automatically assess the distance visual acuity in children aged 18 months to 4 years using the principles of OKN and computer image recognition with tracking technology.It also aimed to describe the distribution of normal visual acuity among children of different age groups.Methods From May to July 2023,children in age groups of 18 months,24 months,30 months,3 years,and 4 years visiting the health examination clinic of Jiangsu Maternal and Child Health Hospital underwent routine pediatric eye health examinations.Additionally,their monocular distance visual acuity was assessed using an automatic OKN visual acuity testing device.The study analyzed the measurable rate of visual acuity in children of different age groups and the distribution of OKN visual acuity values in normal children.Results A total of 655 children were examined,including 339 boys and 316 girls,with an overall measurable rate of82.14%.There were statistically significant differences in the measurable rates among different age groups,which increased with age(χ~2=12.551,P=0.014).After excluding abnormal cases,the 80th percentile values of OKN visual acuity in the right eye of the normal reference population were 4.3 in the 18-month group,4.3 in the 24-month group,and 4.3 in the 30-month group,with no statistically significant differences between any two groups(P=0.260,P=0.990).The 80th percentile value of OKN visual acuity was 4.5 in the 3-year group and 4.6 in the 4-year group,with a statistically significant difference between the groups(P<0.001).Conclusion The automatic OKN visual acuity testing method demonstrated a high measurable rate in children aged 18 months to 4 years.Normal visual acuity values at different stages of early childhood have important practical applications in assessing visual development and detecting eye diseases affecting visual acuity in children.
