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
Objective To explore the refractive status and its distribution of children with visual acuity of 4 ~ 6 years old. Methods The eyesight was examined by international standard vision test. The eye position was examined by the film-imaging method and the occlusion method. The retinal eye drops were treated with 1% atropine eye drops 3 times a day for 3 consecutive days. A total of 25 58 children with low visual acuity were analyzed from four aspects: visual acuity, eye position, refractive, corrected visual acuity. Results The binocular visual acuity was significantly lower in all age groups than monocular visual acuity. Esotropia and exotropia were more common in presbyopia. The refractive status of children with visual acuity of 4 ~ 6 years old were mainly hyperopia. Mostly; degree of refractive error with mild refractive errors, of which the most with mild hyperopia. Conclusion Children aged 4 to 6 years are in the sensitive period of visual development. The refractive status of the eye is hypermetropia. Visual acuity examination, early detection and early treatment are of great significance
