Ocular torticollis is mostly caused by congenital or ocular trauma. The most common is unilateral or bilateral superior oblique paralysis. Paralysis of superior oblique muscle can lead to its hyperfunction against inferior oblique muscle. Ocular torticollis is a compensatory reaction to avoid diplopia caused by the movement disorder of eye muscles in some directions, that is, there are two non-overlapping shadows when seeing things. When the patient's head takes a special posture to make his eyes squint, diplopia will be alleviated or disappeared. Moreover, when the patient adopts this "crooked" head position, it can alleviate the discomfort caused by strabismus, maintain binocular vision and protect visual function.
Long-term crooked head and torticollis will bring facial asymmetry, cervical scoliosis and even scoliosis. It will also be accompanied by corresponding facial deformities, abnormal facial features, bilateral asymmetry, skull deformation, spinal curvature and so on. As long as parents are careful, find early abnormalities in time and seek medical treatment in time, most torticollis can be completely controlled without serious consequences.
