80% of pediatric squint is physiological, and it can heal naturally without intervention until the age of one. However, there are three kinds of cases of squint that should be taken seriously and may have disease factors. 1.Physiological squint The squint that appears 3 months after birth is often a physiological squint, which is caused by the child’s lack of strength in the neck after raising the head and the relative weight of the head. Parents just need to pay attention to observe it. 2.Pathological squint The squint appears about 2 weeks after birth, and there is an obvious lump in the neck. Currently, it is believed that myotonic squint is caused by tension spasm due to lesion of sternocleidomastoid muscle on one side, and the cause may be two factors: one is the increase of intramuscular pressure of sternocleidomastoid muscle, which leads to muscle ischemia and fibrosis. The other is the fibromatosis theory, which is an intramuscular benign fibromatous lesion. Treatment: 80% of myotonic squibs can be cured by physical therapy such as functional exercise, while 20% of those that do not improve by the age of 1 year require surgery to loosen. 3. Ophthalmogenic squint There is no mass in the neck at birth, and the squint appears only at 6 months of age. This condition may be due to strabismus, which usually manifests itself only when positioned with the affected child to look at something, and returns to normal when sleeping. Treatment: Because of the need for the child’s cooperation, oculocutaneous squint must wait until about 1 to 2 years old to be diagnosed, and it cannot be diagnosed before and needs to be reviewed regularly. 4.Bone squint Bone squint is caused by cervical spine deformity. It is caused by a deformity of the cervical vertebrae. It appears after birth and can be accompanied by symptoms such as short neck, also called short neck syndrome. Treatment: Children without discomfort can be treated without intervention. If there is cervical spine slippage and pain, the symptoms can be relieved by surgery. However, to keep the cervical spine stable for a long time, it is also necessary to cooperate with functional exercises. Nowadays, many children with cervical strabismus are over-treated, obviously with physiological strabismus, but they are lobbied by some informal hospitals to do physical therapy, torturing children and parents for nothing. It is advisable to go to a specialist hospital for treatment, rather than just listening to advertisements.
