Preferential Impairment of the Contralesional Posterior Semicircular Canal in Internuclear Ophthalmoplegia [PDF]
Frontiers in Neurology, 2017 BackgroundThe vertical vestibulo-ocular reflex (VOR) may be impaired in internuclear ophthalmoplegia (INO) as the medial longitudinal fasciculus (MLF) conveys VOR-signals from the vertical semicircular canals.
