Pediatric squint is a medical condition called congenital myotonic squint (commonly known as “crooked neck”), which is caused by a fibrous contracture of the sternocleidomastoid muscle on one side, resulting in shortening and a cervical deformity to one side, along with an affected facial development, smaller than the opposite side, and in severe cases, leading to a lateral convexity deformity of the cervical spine. Most children can be completely cured with correct and effective non-surgical treatment in the early stages of the disease. The pathogenesis is mainly intrauterine compression, which is the result of pressure changes caused by the fetal malposition in the uterus. Genetic predisposition is also a cause. About 1/5 of the children have a family history with other partial malformations. In addition, birth trauma, oblique neck occurs in most cases of difficult deliveries, especially in breech births.
