Why do children with cerebral palsy often have strabismus?

There are many causes of strabismus in children. First, congenital strabismus: strabismus can be present at birth, such as esotropia, exotropia, and vertical strabismus. Second, acquired strabismus: for example, strabismus caused by amblyopia. Third, strabismus due to birth injury: damage to the eye muscles during delivery can also lead to strabismus.
