Скачать или смотреть Internuclear Ophthalmoplegia Explained Lesion of the MLF & Eye Movement StudyNeuro

Ever wondered why one eye can’t move properly when looking to the side? In this StudyNeuro Daily Challenge, we break down lesions of the medial longitudinal fasciculus (MLF) and how they cause internuclear ophthalmoplegia (INO). Master this high-yield concept in just 60 seconds — perfect for exams, clinical rotations, and neuro boards.
The MLF is a key brainstem pathway linking the abducens nucleus to the contralateral oculomotor nucleus, coordinating horizontal eye movements. A lesion here results in impaired adduction of the ipsilateral eye while the contralateral eye abducts with nystagmus — a hallmark sign of INO. Understanding this helps in localizing brainstem lesions in patients presenting with diplopia.
