This rare syndrome is caused by the pontine tegmentum’s lesions involving the abducens nucleus, the ipsilateral medial longitudinal fasciculus (MLF), and the facial colliculus. In this case, we report a 68-year-old male patient admitted to our hospital with binocular horizontal diplopia later diagnosed with the eight-and-a-half syndrome. Although the eight-and-a-half syndrome is rare, it should be kept in mind with patients presenting diplopia and peripheral facial palsy simultaneously.}, number={2}, publisher={Istanbul Arel University}, organization={yoktur}
