Half-and-Half Syndrome as Manifestation of Acute Ischemic Stroke (P8-10.005)

Half-and-half syndrome is a rare oculomotor condition when there is impairment of half of the contralateral gaze (due to unilateral internuclear ophthalmoplegia) as well as impairment of half of the ipsilateral gaze (due to injury to the abducens nerve fascicules without damage to the abducens nucleus). There were only three case reports found, two from demyelinating disorders and one from hemorrhage.
