学龄前儿童的屈光异常与弱视调查

A survey for abnormal refraction and amblyopia among the preschoolers

目的了解屈光检查在学龄前儿童弱视普查中的临床用途。方法应用日本尼康手提全自动检影仪对学龄前儿童进行小瞳孔验光,发现屈光有异常的儿童,再进一步进行散瞳检影验光。结果学龄前儿童屈光异常主要以远视散光和混合散光为主,近视与近视散光较少。学龄前儿童屈光异常的发病率是7.87%,弱视发病率为4.04%,接近全国其他同类报告(3.83%)。结论儿童弱视屈光普查优于视力普查,准确性高、效率高。

Aim To find out the incidence of abnormal refraction and amblyopia am ong the preschool children. Methods With Japan-made portable automated retinosc ope, small-pupil optometry was conducted among the preschoolers to detect those with refraction problems, who then were given mydriasis test. Results The incid ence of abnormal refraction and amblyopia among the preschoolers were respective ly 7.87% and 4.04% and the major forms included hypermetropic astigmatism and mi xed-astigmastism. Conclusion With regards to children amblyopia, refraction exa mination is superior to vision examimation, with its high efficiency and exactne ss.
