The occurrence of strabismus in children does not only affect the appearance of the affected child and affects cosmetology. Strabismus is an eye disease that seriously affects the development of binocular vision in children. If not treated as early as possible, for monocular strabismus, it will firstly affect the vision of the child’s skewed eye, leading to a decrease in corrected vision in the strabismic eye and the formation of strabismic amblyopia; secondly, the occurrence of strabismus not only leads to low vision in one or both eyes, but also leads to the disappearance of fusion and the absence of perfect binocular vision, which prevents the child from accurately judging the orientation, position and In other words, we often say that children with strabismus may lose one eye and see with only one eye, and the field of vision of children with strabismus is significantly smaller than that of normal people.
