摘要
目的了解及分析学龄前儿童视力低常眼屈光状态分布特征。方法门诊879例(1663只眼)3~6岁视力低常儿童作为研究对象,检查其视力、眼位、眼前节及眼底,排除眼部器质性病变后对其进行散瞳验光并将结果进行统计分析。结果视力低常儿童双眼784例,占89.19%,单眼95例,占10.81%;裸眼视力0.9者11只眼,占0.66%;0.6~0.8者640只眼,占38.48%;0.2~0.5者936只眼,占56.28%;≤0.1者76只眼,占4.57%。学龄前儿童视力低常眼屈光类型以远视性屈光不正为主,其中又以复性远视散光为多见。视力低常儿童屈光程度以轻度屈光不正为主占76.67%其次为中度占18.28%,而重度屈光不正仅占5.05%。结论学龄前儿童视力低常眼屈光主要为远视性屈光不正,其与弱视发生呈正相关,所以对视力低常眼进行必要的屈光检查,早发现、早治疗具有重要的临床意义。
Objective To know and analyze the distribution characteristics of refractive state for preschool children with subnormal vision eyes. Methods A total of 879 outpatient children （1663 eyes） aged 3-6 years old with subnormal vision as study subjects, and examination were made on eyesight, eye position, anterior segment and eyeground to exclude organic lesion. They received mydriatic refraction and the results were statistically analyzed. Results There were 784 cases with subnormal vision in binoculus , accounting for 89.19%, and 95 cases in monocular, accounting for 10.81%. There were 11 eyes with uncorrected visual acuity as 0.9, accounting for 0.66%, 640 eyes as 0.6-0.8, accounting for 38.48%, 936 eyes as 0.2-0.5, accounting for 56.28%, and 76 eyes as ≤0.1, accounting for 4.57%. Preschool children had ametropia types mainly for hyperopie refractive errors, and hyperopic compound astigmatism was more prevalent. Subnormal vision children had mild refractive errors accounted for 76.67%, moderate refractive errors accounted for 18.28%, and severe refractive errors accounted for 5.05%. Conclusion Preschool children have ametropia types mainly for hyperopic refractive errors, and it is positively correlated with amblyopia. The necessary refractive examination to the subnormal vision eves has important clinical significance to early detection and early treatment.
