Abstract:
Wall-eyed monocular internuclear ophthalmoplegia (WEMINO) is a rare variant of internuclear ophthalmoplegia (INO), consisting of unilateral INO and ipsilateral exotropia. This distinctive syndrome is probably associated with damage to the medial longitudinal fasciculus. However, WEMINO caused by a midbrain lesion has not been previously reported. We herein report a 50-year-old man presenting with WEMINO and vertical gaze dysfunction resulting from infarction of the midbrain tegmentum.
