摘　　要：目的探讨不同年龄组的立体视发育规律及儿童立体视成熟期。方法197人(3～38岁)分为学龄前儿童组、学龄儿童组、青少年组和成人组,用颜氏立体图对每组进行了远近立体视锐度、近的交叉视差和非交叉视差阈值检测。结果(1)学龄前儿童组,近立体视锐度正常率高于远立体视锐度,两者的差异有显著性(P<0.05),其余各组两者之间的差异无显著性(P>0.05)。(2)远立体视锐度,学龄前儿童组正常率低于其余各组(P<0.05);近立体视锐度各组之间差异无显著性(P>0.05)。(3)学龄前儿童组和学龄儿童组中,非交叉视差正常率高于交叉视差(P<0.05);青少年组和成人组,交叉与非交叉视差正常率差异无显著性(P>0.05)。(4)交叉视差,青少年组和成人组正常率高于学龄前儿童组和学龄儿童组(P<0.05)。非交叉视差,四组之间差异无显著性(P>0.05)。结论远近立体视锐度、交叉与非交叉视差的发育是不同步的,立体视功能要到12岁后才发育成熟。同时提示:临床立体视功能检查应进行远近立体视测定;并应测定立体视锐度,交叉视差、非交叉视差的阈值。Objective To study the development of stereopsis in different age group and the stereopsis maturing period. Methods 197 cases of 3 to 38 years old was divided into four groups:preschool children group,school children group, juvenile group and adult and adult group. Far stereopsis acuity, near stereopsis acuity, crossed disparity and uncrossde disparity were examined with Yan tests in each group. Results (1) The normal ratio of near stereopsis acuity in the preschool children group is better than that of far stereopsis acutiy(P>0.05). But there is no statistically significant difference between the normal ratio of far stereopsis acuity and that of near stereopsis acuity in other groups. (2) The normal ratio of far stereopsis acuity in the preschool children. group is wores than that other groups(P<0.05). But the normal ratio of near stereopsis acuity has no statistically significant difference between other groups. (3) The normal ratio of uncrossed disparity in the preschool children group and school children guorp is better than that of crossed disparity (P<0.05). But the normal ratio of uncrossed disparity in the juvenile group and adult group is as good as that of crossed disparity.(4)The normal ratio of crossed disparity in the juvenile group and adult guoup is better than thatin the preschool children group and school children group,The normal ratio of uncrossed disparity has no statistically singificant difference between four grous. Conclusions The results suggest that the development of far stereopsis acuity,near stereopsis acuity,crossed disparity and uncrossed disparity are different.Thestereopsis maturing period is over the age of 12 years. The results also suggest that stereopsis examination is a systemic examination that should include the examination of far stereopsis acuity, near stereopsis acuity, crossed disparity and uncrossed disparity.
