Internuclear Ophthalmoplegia

Excerpt

Internuclear ophthalmoplegia is an ocular movement disorder caused by a lesion of the medial longitudinal fasciculus. It is characterized by impaired adduction of the ipsilateral eye with nystagmus of the abducting eye. Although the medial longitudinal fasciculus was identified in the 1870s, internuclear ophthalmoplegia was first described in 1903.
