间歇性外斜视儿童动态和静态立体视觉的对比分析

Analysis of the children's dynamic and static stereopsis of intermittent exotropia

目的：对比分析间歇性外斜视儿童在动态与静态刺激背景下的立体视功能。方法：选取5～12岁的间歇性外斜视儿童56例,其中男26例,女30例,采用多维空间感知觉训练软件分别进行动态与静态刺激背景下的立体视功能检查,比较不同刺激下的立体视功能。结果：动态与静态立体视均存在的患者17例（30%）,动态或/和静态立体视功能有缺损者39例（70%）,在39例有立体视缺损的患儿中,仅存在静态立体视的患者10例（26%）,仅存在动态立体视者25例（64%）,立体视缺失者4例（10%）。间歇性外斜视患儿动态立体视的检出率高于静态立体视的检出率,差异有统计学意义（P〈0.05）。结论：间歇性外斜视儿童动态背景下的立体视功能优于静态背景下的立体视功能。

AIM： To compare and analyze the stereopsis of intermittent exotropia children under the different backgrounds of dynamic stimuli and static stimuli.METHODS： We collected 56 children（male 26,female 30 with intermittent exotropia at the age from 5 y to 12 y and examined their stereopsis under the different backgrounds of dynamic stimuli and static stimuli using a multidimensional sense perception training software. The differences between the dynamic stereopsis and static stereopsis were compared. RESULTS： Totally 17 cases（ 30%） had both dynamicstereopsis and static stereopsis,39 cases（70%）had either dynamic or static stereopsis deficit,only 10cases（ 26%） had dynamic stereopsis,25 cases（ 64%）static stereopsis left and 4 cases（10%） were without any form of stereopsis. The positive rate of dynamic stereopsis was better than the positive rate of static stereopsis,with statistical significance（P〈0. 05）. CONCLUSION： Dynamicstereopsis is better than the static stereopsis to intermittent exotropia children.
