What causes strabismus?

First, the extraocular muscles have balance problems. Extraocular muscles are divided into superior rectus, inferior rectus, superior oblique, inferior oblique, lateral rectus and medial rectus. If the strength of lateral rectus is stronger, the eyes will deviate outward. If the strength of medial rectus is stronger, the eyes will deviate inward.

Second: congenital strabismus caused by genetic factors, or the baby in the production process by external stimulation.

Third, the development of children's nervous system is not perfect. Binocular vision is not perfect before the age of five. During this period, strabismus may be caused by trauma, shock or convulsion after fever. This kind of neurotic strabismus, if treated in time, can slowly recover in three months. After five years old, its stereopsis function has developed perfectly, this kind of situation is relatively rare.
