It is a common disorder in children. A small number of cases caused by bad habits can disappear on their own without treatment. However, persistent squint can lead to asymmetric facial development, affect the development of the neck bones and even cause cervical scoliosis, and in severe cases, may also cause deformities in the development of the mandible. There are many reasons for the child’s squint, so it is important to find out the specific cause of the child’s squint before treating the child to achieve good results. Myotonic squint The child shows abnormal contracture or fibrosis of the neck muscles, resulting in restricted movement of the neck and a tilted head. A hard knot-like mass, similar to a tight rope, can be felt in the sternocleidomastoid muscle on one side of the child’s neck, which can be improved by physiotherapy and other methods in the early stage, while some children must be surgically released. A few parents do not pay attention to myelomeningocele and delay the treatment of their children. In serious cases, it can cause deformation of the cervical vertebrae and insufficient blood supply to the brain, resulting in dizziness, headache and reduced intelligence. Bony squint This is caused by congenital malformation of the cervical spine, and can be accompanied by symptoms such as short neck, and in severe cases, the movement of the neck is obviously restricted. If the child has no discomfort, no special treatment is needed. If there is discomfort such as cervical spine slippage and pain, surgery is needed to improve the symptoms, and post-operative functional exercises are also essential. Ophthalmic squint Most of the cases are caused by congenital paralysis of the eye muscles, most commonly the superior oblique muscle paralysis of one or both eyes, which is a type of squint that is often overlooked clinically. For children whose neck muscles and bones are not found to be significantly abnormal and whose tilted head does not improve, they need to be highly alert to supraocular oblique muscle palsy, which can lead to impaired eye movement in certain directions and the phenomenon of double vision. However, the “protective” effect of this head tilt is only short-lived, and if the eye muscle abnormalities are not improved in the long term, more muscles will be damaged and stereo vision will eventually be lost. Therefore, once oculocerebral tilt is diagnosed, it needs to be treated with ophthalmic surgery as soon as possible, and most children can improve their tilted head after surgery.
