Does central pontine myelinolysis cause pupils to shrink?

Central pontine myelinolysis is a condition that may cause miosis, usually involving the oculomotor nerve, and is caused by chronic wasting disease or rapid correction of hyponatremia. The disease is characterized by sudden onset of delayed quadriplegia, mastication disorders, swallowing disorders, speech disorders, eye gaze disorders, and even mydriasis. Severe patients may exhibit atresia syndrome, and soon the patient dies. Its main auxiliary examinations include magnetic resonance imaging of the head. This disease needs to be differentiated from pontine tumor and multiple sclerosis. Central pontine myelinolysis is critical. After onset, you should go to hospital immediately to prevent delay.
