Abstract 

Internuclear ophthalmoplegia (INO) is characterized by pathognomonic findings on neurological examination. It results from a lesion in the medial longitudinal fasciculus (MLF) and is rarely caused by head trauma. The neuroanatomy of INO is complex and the mechanism by which trauma causes this syndrome is controversial. In the context of trauma, INO occurs frequently in association with other neurological findings and should prompt a thorough investigation and ICU admission. A case of an individual with acute post-traumatic INO is reported and discussed.
