What is infantile esotropia?

summary

Now many children have strabismus, two eyes can not look at a target at the same time, but only with one eye, the other eye's axis of vision shows different degrees of deviation, this phenomenon is called strabismus. The degree of deviation of strabismus can be obtained by measuring the angle between the axes of two eyes. What is infantile esotropia? Now let me tell you something.

What is infantile esotropia?

First: congenital anomaly: this kind of strabismus is mainly caused by congenital abnormal position development of extraocular muscle, abnormal development of extraocular muscle itself, incomplete differentiation of mesoderm, poor separation of ocular muscle, abnormal muscle sheath, fibrosis and other anatomic defects or nerve palsy dominating the muscle. In some cases, the use of forceps in the process of production caused head and face injury of the baby or excessive force of the mother in the process of production caused fetal intracranial pressure rise, resulting in cerebral punctate hemorrhage, and the hemorrhage happened to cause extraocular muscle paralysis at the nerve nucleus which dominates the eye movement.

Second: development is not perfect: children, especially infants and young children binocular single vision function development is not perfect, can not coordinate the extraocular muscles, any unstable factors can promote the occurrence of strabismus. People's single vision function is gradually developed after birth. This kind of function, like visual function, is gradually developed and matured by repeatedly receiving the stimulation of clear images from the outside world. After 2 months of birth, the baby only has the general image fusion, the establishment of accurate image fusion function should last until after 5 years old, and the establishment of stereopsis is the latest, and it can approach the adult at the age of 6-7 years old.

Third: 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 eyes, and because children's cornea and lens have large bending force, ciliary muscle contraction force is strong, that is, the adjustment force is strong. 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.

matters needing attention

The prevention of strabismus should start from infancy. Parents should pay attention to carefully observe the development and changes of children's eyes. If any abnormality is found, they should go to the hospital for examination and treatment in time.
