How does squinting in young children occur?

Children show strabismus for many reasons. Strabismus before the age of two is considered to be caused by congenital factors. If strabismus is shown within 5 years of age, it may be caused by abnormal visual development. If strabismus is shown in children, it is recommended that a comprehensive and systematic examination should be carried out, and then symptomatic treatment should be taken according to the patient's condition. Strabismus treatment is mainly surgery or non-surgical treatment.
