    目的:在小学生的视觉普查中增加立体视项目，对近视，远视，屈光参差，弱视，斜视检出率的影响及意义。

    方法:对温州市2933名小学生进行TNO立体视图的检查、裸眼远视力、眼位检查、散瞳后电脑验光、裂隙灯检查、眼底检查。

    结果:立体视异常在正常人群、近视、远视、混合散光、弱视、斜视、其他眼病的发病率分别为7.37%、13.12%、57.49%、51.43%、83.87%、93.10%、88.89%，立体视异常在屈光参差（1-2D）、屈光参差（2.25D以上）的发病率分别为52.83%和87.5%。

    结论:在小学生的视觉普查中增加立体视项目有利于提高对近视，远视，屈光参差，弱视，斜视检出率，同时能够及早发现小学生的立体视异常，进行早预防，早治疗。

    Objective: To investigate the stereopsis vision related with the prevalence of myopia, hyperopia, anisometropia, amblyopia and strabismic in primary school students vision survey.

    Methods: Examinations included TNO test, distant vision to the naked eye, the eye position, computer optometry after dispersing pupil ,examination with slit-lamp and fundus examination was applied to 2933 primary school students in Wenzhou.

    Results: The incidence of abnormal stereopsis in normal, myopia, hyperopia, mixed astigmatism, amblyopia, strabismic and other eye disease was 7.37%, 13.12%, 57.49%, 51.43%, 83.87%, 93.10%, 88.89%, and the incidence of abnormal stereopsis in anisometropia（1-2D）and anisometropia（>2.25D） was 52.83% and 87.5%。

    Conclusions: In primary school students vision survey, the examination of stereopsis vision is favourable favourable to improve the detection rate of myopia, hyperopia, anisometropia, amblyopia and strabismic, and can find abnormal stereopsis in pupil in time. This is helpful to prevent and treat abnormal vision
