间歇性外斜视(IXT)是一种发病率高、斜视角度多变、双眼视觉功能不同程度受损的眼科常见疾病。双眼视觉功能缺损与视觉皮层的改变有关，IXT涉及包括双眼融合相关皮质区域在内的多个脑区的功能改变，部分IXT患者在矫正眼位后，大脑皮层的异常改变依然存在，双眼视觉的恢复仍然困难。针对这些问题，视感知觉训练逐渐应用到IXT患者术后双眼视觉功能的重建中，视感知觉训练从大脑层面修复视觉皮质，通过不断刺激视觉中枢，提高大脑视皮层处理信息的能力，进而修复视觉中枢功能，使患者获得良好的双眼视觉功能，稳定眼位，减少复发。本文就IXT患者双眼视觉损伤机制以及视感知觉训练在IXT治疗中的作用做一综述。希冀为视感知觉训练重建IXT患者术后双眼视觉功能、降低复发率提供更多证据。

[Abstract]
Intermittent exotropia(IXT)is a common ophthalmic disease with high incidence, variable deviation, and varying degrees of impaired binocular visual function. The defect of binocular visual function is related to the changes of visual cortex. IXT involves the functional changes of many brain regions, including the cortical areas related to binocular fusion. After correcting the eye position, the abnormal changes of cerebral cortex still exist in some patients with IXT, and the recovery of binocular vision is still difficult. In order to solve these problems, visual perception training is gradually applied to the postoperative reconstruction of binocular visual function in patients with IXT. Visual perception training repairs the visual cortex from the brain level, improving the ability of the visual cortex to process information by constantly stimulating the visual center, thus repairing the visual central function, so that patients can obtain good binocular visual function, stabilize the eye position and reduce recurrence. This article reviews the mechanism of binocular visual impairment and the role of visual perception training in the treatment of IXT. It is hoped to provide more evidence for visual perception training to reconstruct postoperative binocular visual function and reduce the recurrence rate in patients with IXT.
