采用标准方法对１２４２名７周岁儿童２４８４只眼进行视力测定，并对其中１１４３人（普查率为９２％）２２８６只眼用１％阿托品麻痹睫状肌后，进行视网膜检影。视力低常率为３１．５６％。近视眼３２人，占２．８０％，正视眼３４人，占２．９７％，远视眼１０７７人，占９４．２３％。测得２１０２只眼的屈光生理值为＋１．４０±０．５９Ｄ（男性＋ｌ．３９±０．５８Ｄ，女性１．４０±０．６１Ｄ）。对７岁儿童视力低常率较高的现象进行了分析。重点就７岁儿童屈光生理值与以往报告的４～６岁儿童测定的结果作了比较，并对生理值的意义进行了讨论。
A total of 1,284 eyes of 1284 children aged 7 years were examined by standard methods and 1,146 of them (census rate was 92%) were enrolled in 2286 eyes with 1% atropine and paralyzed ciliary muscles. Low vision rate was 31.56%. Myopia 32, accounting for 2.80%, adhering to 34 eyes, accounting for 2.97%, 1077 hyperopia, accounting for 94.23%. The refractive physiological values of 2102 eyes were measured as + 1.40 ± 0.59D (+ l.39 ± 0.58D for men and 1.40 ± 0.61D for females). The phenomenon of high vision loss in 7-year-old children was analyzed. Emphasis was placed on the comparison of the refractive values of children aged 7 years old with those of children aged 4 to 6 years previously reported. The significance of physiological values was also discussed.
