正常和弱视儿童立体视锐度测定

Study on Strereopsis in Normal and Amblyopic Children

目的：研究正常儿童立体视税度年龄特征及弱视儿童立体税税度异常率。方法：用票屋忍的新立体视检查图（ANST）对300名3～12岁正常儿童和100例弱视儿童立体视税度进行了测定。结果：正常儿童中997％立体视锐度通过≤60秒，中度和重度弱视组和斜视性弱视组患儿立体视异常率达92．1％～100．0％。结论：儿童立体视的成熟期在3岁以前，弱视儿童生体视异常率高的现象应引起关注。

Objective: To study the age characteristics of the normal children' stereopsis and the prevalence of abnormal stereopsis in children with amblyopia Methods: S. Awaya New Sterec Tests (ANST)were made among 300 normal children and 100 amblyopic children 3 ~ 12 years of age. Results: The percentage of children with stereoacuity equal to or below the critical level of 60 seconds was 99. 7% among the normal children. In children with middle amblyopia or serious amblyopia or strabismic amblyopia, the prevalence rates of abnormal stereopsis(> 60s) were 92. 1 % ~ 100%. Denclusions: More attention sheuld be paid to the higher prevalence rate of abnormal steroopsis among children with amblyopia.
