How does infantile strabismus form reason?

summary

Many parents find that their children are different from other people's families, and their eyes can not be focused in the same direction. If this is the case, you should be careful. This is a symptom of strabismus. Let's take a look at the following.

How does infantile strabismus form reason?

First, this kind of strabismus is caused by congenital abnormal position development of extraocular muscles, abnormal development of extraocular muscles themselves, or paralysis of nerves dominating muscles.

Second: there are also genetic factors. Strabismus is not inherited by all members of the family. This defect is often indirectly inherited to the next generation of children. Generally, strabismus within 6 months of birth is called congenital strabismus. It does not have the basic conditions for the establishment of binocular vision and does great harm to the development of visual function.

Third: because the development of children's body is not perfect. Children, especially infants and young children, binocular vision function is not perfect, can not coordinate the extraocular muscles, any unstable factors can promote the occurrence of strabismus.

matters needing attention

The characteristics of eyeball development make children prone to strabismus. Because children's eyeball is small, eye axis is short, most of them are hyperopia, and because children's cornea and lens have great bending force, ciliary muscle has strong contraction force, that is, strong adjustment force. Such children want to see objects need more adjustment force, at the same time, both eyes also force to turn inward, resulting in excessive radiation, easy to cause esotropia, this kind of esotropia is called accommodative esotropia.
