Postural strabismus is a crooked neck caused by poor posture. Postural tilt occurs mostly in children, due to the imbalance of the muscles on both sides of the neck caused by poor posture, one side of the muscles are tense, and the movement of the neck is limited. Due to the imperfect development of children’s neck muscles, they are unable to control their head posture well enough to cause tilting to one side. Postural strabismus can develop into habitual strabismus if not corrected, and some may have strabismus. It is important to change the bad posture in daily life, sleep on both sides of the bed, and massage the tense muscles. You can also wear orthotics to correct the problem, and most of them can be corrected. Postural strabismus should be consulted as soon as possible and treated under the guidance of a doctor.
