Exotropia does not usually require surgery for intermittent exotropia, but if it is a constant exotropia, surgery is required. Exotropia is one of the eye diseases, which can be divided into intermittent and constant exotropia. Intermittent exotropia belongs to a kind of transitional strabismus, sometimes the patient is in the state of exotropia, and sometimes the patient is able to control the eyeball’s orthoptic position, which can be restored by itself with the growth of age, so it usually does not need to be treated by surgery. For constant strabismus, most of them are caused by congenital development or hereditary factors, which may affect the development of vision and cause blurred vision, and usually cannot be recovered by themselves. It can be corrected through surgical methods in order to achieve the recovery effect, such as by cutting off the displacement suture and other methods. However, it can also be corrected by wearing glasses. Regular checkups should be done in the hospital to keep track of the eye’s recovery and to take targeted measures to improve the condition.
