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 understand and analyze the distribution of refraction status of presbyopic eyes in preschool children. Methods A total of 879 cases (1663 eyes) of children with visual acuity of 3 ~ 6 years old were selected as study subjects. Visual acuity, eye position, anterior segment and fundus were examined, and mydriatic optometry was performed to exclude eye organic disease and the results were obtained conduct statistical analysis. Results There were 784 eyes (89.19%), 95 eyes (10.81%) with uncorrected visual acuity, 11 eyes (0.66%) with uncorrected visual acuity (0.9 eyes), 640 eyes (0.6% ~ 0.8 eyes) Only eyes, accounting for 56.28%; 76 eyes ≤ 0.1, accounting for 4.57%. Preschool children with low visual acuity refractive refractive hyperopia mainly myopia, of which hyperopia astigmatism is more common. Children with low vision were mainly mild refractive errors accounted for 76.67%, followed by moderate accounted for 18.28%, while severe refractive errors accounted for only 5.05%. Conclusions Preschoolers with low visual acuity are mainly hyperopic refractive errors, which are positively correlated with the occurrence of amblyopia. Therefore, it is of great clinical significance to make necessary refractive examinations for low vision eyesight. Early detection and early treatment have important clinical significance.
