生理性近视眼

作者统计分析1999名学生及学龄前儿童(4～18岁)正常眼的视力及睫状肌麻痹下的屈光,发现各年龄组屈光度都可计算出一定范围的正常值,并呈现正态分布曲线。结合其他观察比较,特提出生理性近视眼的概念,并就其表现特点及其与病理性近视眼的区别,作了详细讨论。对于人群中大量存在的生理性近视眼(或称单纯性近视眼),作者认为可看作是现代文明社会中的一种适应性结果,属于一类生物学变异,而不是一种眼病。

PHYSIOLOGIC MYOPIA

A determination of oycloplegio refraction and visual acuity for 1999 healthy Chinese students and children from 4 to 18 years of age was made. It was found that the distribution of refractive variation of the sample follows a curve of normal one. According to this survey and other observations, the authors present a concept of "physiologic myopia". The characteristics about the physiologic myopia, the differences between physiologic and pathologic myopia, and the physiologic value of refraction of various groups of age have been discussed in detail. In the article, the physiologic (or "simple") myopia among the population has been considered as a biologic variation in modern civilization, and not an illness.
