258例视力低常儿童屈光状态分析

目的　探索 4～ 6岁视力低常儿童的屈光状态及其分布规律。方法　用国际标准视力检查视力 ,以象膜映光法及遮盖法检查眼位 ,1%阿托品眼水点眼 ,每日 3次 ,连续 3d后进行检影验光 ,3周后配镜。对 2 5 8例视力低常儿童从视力、眼位、屈光、矫正视力等 4个方面进行分析。结果　各年龄组双眼视力低常均多于单眼视力低常 ;内斜视、外斜视均以远视多见 ;4～ 6岁视力低常儿童的屈光状态均以远视为主 ,且以复性远视散光居多 ;屈光不正的程度以轻度屈光不正为主 ,其中又以轻度远视最多。结论　 4～ 6岁儿童处于视觉发育的敏感期 ,眼的屈光状态多为远视 ,对其进行视力屈光检查 ,早发现、早治疗具有重要意义

An Appraisal of Diopter State of Children with Subnormal Vision

Objective To evaluate diopter state and its distribution of children with subnormal vision at 4-6 years. Methods Sight was examined with international standard chart and eye place was checked by cornea illumination and covering methods. The eyes were put 1% atropine 3 times per day for 3 consecutive days and optometry was made. Four aspects i.e. sight, eye place, diopter, correct faulty vision, of 258 children were analyzed. Results Subnormal vision of both eyes was more than that of single eye. Inside strabismus and outside strabismus were often observed in children with long sight. The long sight was the main diopter state of the children. Ametropia degree was milder in most of the children. Of them, milder long sight was the most common state. Conclusions Children at age of 4-6 were on sensitive development period of vision growth. Long sight was the most common state of the children. It was important to examine vision and diopter of the children in order to early discovery and early treatment.
