12～14岁视力不良学生眼屈光状态测定

The Determination of Refraction Status in Students with Visual Debility Aged 12～14

对12～14岁学生远视力低于正常、近视力正常的346名青少年学生进行眼底检查除外屈光不正以外的其它眼疾，在睫状肌麻痹下检影验光，结果发现：正视眼43只（6．2％），近视眼627只（90．6％），远视眼22只（3．2％）；近视眼按年龄和近视程度分类进行统计分析，随年龄增长近视屈光度升高：12岁组与13岁组间、12岁与14岁组间近视屈光度均有显著差异；随着年龄的增长，低度近视的比例减少，而中度、高度近视的比例增加。在防治近视工作中，不应仅以远视力作为唯一指标，必需在睫状肌麻痹下检影验光方可了解屈光状态，再采取不同的防治措施。

The visual acuity and ocular fundus of 362 students aged 12-14 were examined,They had normal visual near sight and visual far blurred. The refraction status of 346 students(692 eyes) wete determined with cycloplegic retinoscopy .The rusults showed that 90. 6% were myopia, 9. 4% were pseudomyopia (6. 2% were emmetropia, 3. 2% were hyperopia). There were considerable differences between 12 and 13, 12and 14 years old groups, in the refractive power of myopia. This phenomena was discussed. The results provided some evidence of refractive development of human eye.
