Abstract

Internuclear ophthalmoplegia(INO)is a horiwntal ocular motor disturbance caused by a lesion of the medial longitudinal fasciculus. We have experienced a case of bilateral internuclear ophthalmoplegia associated with exotropia, which revealed the symptom of bilateral impairment of adduction and dissociated nystagmus of the abducting eye on horizontal gaze in either direction. No bilateral internuclear ophthalmoplegia caused by trauma has yet been reported in this country. Here we report the case of the trauma-related medial longitudinal fasciculus lesion and its pathophysiology along with a literatural review.
