What causes strabismus?

The problem of strabismus cannot be ignored. If we want to effectively improve and solve it, we need to pay attention to analyzing and understanding the causes, such as common visual dysfunction, or some eye diseases in children, as well as trauma or congenital problems.

1. Visual dysfunction

Generally, the visual center of children's brain is not fully developed, so they cannot coordinate and control the contraction and extension of the extraocular muscles well. Therefore, the single vision function of children's eyes is unstable and imperfect. At this time, any certain external factors such as fright, fever, trauma and other stimuli may lead to the weakening or even loss of the unstable single vision function of the eye.

2. Factors related to children's eyes

Generally, children have relatively short eyeballs and most of them suffer from physiological hyperopia. Generally, children's need to look at nearby objects gradually increases after they are two years old. Moreover, children's eyes have a strong ability to adjust and their eye muscles have good contraction force. If children have the habit of looking at things very close since childhood, their eyes will be in a state of high adjustment for a long time, which will cause the eyeballs to turn inward, and in the long run will lead to esotropia.

3. Congenital and birth injury factors

Generally, children's congenital extraocular muscles are not fully developed; the nerves that control the movement of the extraocular muscles are congenitally paralyzed; the mother's difficult labor causes damage to the extraocular muscles and extraocular muscle nerves, all of which can cause deviation of the eyeball position.
