1. Non-surgical treatment of strabismus, firstly, aims at amblyopia to promote good vision development of both eyes, and secondly, corrects deviated eye position. The treatment of strabismus includes: wearing glasses, wearing an eye mask to cover it, and training in orthophoto. Wearing an eye mask is the main method to treat strabismus amblyopia. Eye muscle surgery involves relaxing (weakening) or shortening (strengthening) one or more muscles in the extraocular muscles of one or both eyes. Mild strabismus can be corrected by wearing a prism. In-situ training can be used as a supplement before and after operation. 2. The younger the strabismus surgical treatment, the better the treatment effect. Strabismus surgery is not only to correct eye position and improve appearance, but also to establish binocular vision function. The best time for surgery is before the age of 6 ~ 7. Binocular vision training was performed after operation to enhance and maintain stable stereoscopic vision function.
