Abstract:

Binocular vision is an important indicator for evaluating the visual quality of ophthalmic patients. Helping patients rebuild binocular vision is an effective way to improve visual quality. The point of which the “critical period” of visual development is before 9 years old. Abnormal visual experience can damage the function of visual cortical neurons, leading to the destruction of binocular vision. Visual perception training uses behavioral visual training, de-suppression therapy, and synoptic training to improve the contrast sensitivity and stereoscopic visual acuity of patients with strabismus and amblyopia. In particular, the therapy based on visual perception treating binocular vision dysfunction has been widely used in rehabilitation training of binocular vision.
