大面积脑梗死通常由颈内动脉主干、大脑中动脉主干或皮层支的完全性卒中所致,表现为病灶对侧完全性偏瘫、偏身感觉障碍及向病灶对侧的凝视麻痹。病程呈进行性加重,易出现明显的脑水肿和颅内压增高征象,甚至发生脑疝死亡[1]。早期发现大面积脑梗死的重要体征、及时治疗,可减少死亡率、致残率。眼球同向凝视是大脑半球受损的重要体征之一,是由皮质侧视中枢额中回后部破坏性病变引起两眼向受损半球侧同向凝视,凝视瘫痪肢体的对 Large-area cerebral infarction is usually caused by a complete stroke of the trunk of the internal carotid artery or the trunk or cortical branch of the middle cerebral artery. Complete cerebral hemiplegia, hemifacial sensation, and paralyzed paralysis to the contralateral side of the lesion are manifested. The course of the disease was progressive increase, prone to significant signs of cerebral edema and increased intracranial pressure, and even death of herniation [1]. Early detection of large signs of cerebral infarction, timely treatment, can reduce mortality and morbidity. Eye with the same direction is one of the important signs of damage to the cerebral hemisphere, is the middle of the cortex by the back of the Central Front Back destructive lesions caused by the two eyes to the damaged hemisphere side to the same gaze, staring paralyzed limb pairs
