How does strabismus form?

Strabismus may be caused by genetic factors, trauma or refractive abnormalities.

1. Genetic factors

strabismus may be caused by genetic factors, family or parents with strabismus are more likely to occur strabismus than normal people.

2. Trauma

may also cause strabismus, such as infant birth injury, orbital fracture caused by local muscle incarceration, cardiovascular accident caused by nerve paralysis or brain trauma.

3. Refractive

normal eyes can maintain eye alignment through convergence ability, while patients with obvious refractive abnormalities such as myopia, hyperopia or amblyopia, eye accommodation ability and convergence ability are poor, may gradually cause strabismus.
