间歇性外斜视患者的远近立体视功能研究进展

Advances in near and distance stereopsis of patients with intermittent exotropia

间歇性外斜视是临床上最常见的一种外斜视类型,可对远近立体视功能造成不同程度的损害。手术矫正眼位后,间歇性外斜视患者的远近立体视功能可得到不同程度的改善。立体视功能为评估双眼合作不协调的间歇性外斜视患者提供了一个评估双眼视功能的有效方法,且对手术时机的选择及术后双眼功能恢复评价有指导作用。本文对近年来间歇性外斜视患者的手术治疗前后立体视功能的研究进展作一综述。

Intermittent exotropia is the most common type of exotropia, which can lead to varying degrees of damage on distance and near stereopsis. These functions can be improved to some degree in patients with intermittent exotropia after alignment by the surgical correction. Stereoscopic visual function evaluation provides an effective method to evaluate binocular visual function for intermittent exotropia patients whose eyes are not in harmonious cooperation. Besides, stereopsis can play a guiding role in choosing operation time and evaluating binocular function postoperatively.
