Abstract
Eight-and-a-half syndrome (EHS) is a rare neuro-ophthalmologic condition characterized by conjugated horizontal gaze palsy, internuclear ophthalmoplegia (INO), and ipsilateral fascicular seventh cranial nerve palsy. Clinical features are attributed to the involvement of the lower pontine, including the abducens nucleus, ipsilateral medial longitudinal fasciculus (MLF), and adjacent facial colliculus. Etiology includes vascular diseases such as pontine infarction or ischemia, demyelinating conditions at the level of the pons, and rarely space-occupying lesions.
