目的 探讨视力正常青少年的屈光状态。方法 采用 1%阿托品麻痹睫状肌后检影验光 ,测定 6～ 18岁青少年 2 62 8只视力正常眼的屈光度。屈光类型按检影实际结果 ,本文以 <± 0 2 5D为正视 ,≥± 0 2 5D分别为远视类型或近视类型。结果 本组轻度远视占 91 2 1% ,≥± 3 2 5D占1 71% ;近视占 2 89% ;正视仅占 4 19%。各年龄组屈光度峰值都不在正视处 ,6～ 12岁组之间峰值有规律地向近视侧偏移。三种屈光类型比例的变化在 6～ 12岁组与年龄相关 ,12～ 18岁组变化与年龄增长的相关性无统计学意义。结论 青少年的正常屈光状态为轻度远视。几何光学的“正视眼”与生物医学角度的屈光“正常眼”是两个不同概念 ,应予以区分
Objective To study the refractive status of normal vision young people. Methods 1% atropine was used to paralyze the ciliary muscle after retinoscopy, and the diopter of 2 628 eyesight normal eyes of 6 ~ 18 years old children were measured. Refractive type according to the actual results of retinoscopy, this article to <± 0 2 5D as the front, ≥ ± 0 2 5D were myopia type or type of myopia. Results This group of mild hyperopia accounted for 91 2 1%, ≥ ± 32D accounted for 1 71%; myopia accounted for 89% 89%; The peak refraction of all age groups are not in the front office, 6 to 12-year-old peak regularly to the myopic shift. The changes of the proportions of the three types of refraction were age-related in the age group of 6 to 12 years, and there was no significant correlation between the changes in the age group of 12 to 18 years and the age. Conclusion The normal refractive status of adolescents is mild hyperopia. Geometrical ophthalmology and biomedical refractive “normal eye” are two different concepts, should be distinguished
