怀柔城区和郊区学龄前儿童视觉状况调查

目的：对怀柔区25个幼儿园（其中区中心15个,郊区10个）4~6岁学龄前儿童进行视觉状况的普查,比较城区和郊区儿童视觉状况。方法：2009年分别对城区2150例儿童和郊区1679例儿童进行了视觉检查,包括远近视力（裸眼和戴镜视力）、外眼检查、眼位及眼球运动。对视力〈0.8者进行散瞳验光。结果：怀柔区城区和郊区儿童视力低常率有显著性差异（13.02%vs 9.17%,P〈0.01）。视力低常率：4岁组为8.63%,5岁组14.67%,6岁组10.31%。各年龄组视力低常率有统计学意义（P〈0.01）。视力低常的病因有屈光不正、斜视、先天眼病（先天上睑下垂和先天眼球震颤）及眼外伤,其中屈光不正占96.31%,包括远视（74.16%）、近视（10.77%）和混合散光（15.07%）。弱视患病率4.3%,以轻度弱视居多,屈光不正（46.06%）是形成弱视的主要原因。结论：学龄前儿童视力低常率和地域有一定的关系。低常率随年龄增加而降低,表明儿童视功能发育逐渐成熟。远视是4~6岁学龄前儿童视力低下的主要原因。儿童视觉普查应加强近视、斜视、弱视的普查,以做到早发现早治疗。
