Two cases of horizontal eye movements disorders due to pontine lesions are reported and their clinical symptoms described. Case 1, a 52-year-old female, showed right lateral gaze paralysis together with right facial paralysis, vestibular dysfunction and scanning speech after surgery on an epidermoid cyst in the 4th ventricle. Case 2, a 56-year-old female, displayed right lateral gaze paralysis combined with right facial paralysis, vestibular dysfunction, right deafness and left hemiplegia following pontine hemorrhage. The right lateral gaze paralysis of both cases were analyzed and speculated to have resulted from combined disorders of the right abducens nucleus, the right PPRF (paramedian pontine reticular formation) and the right MLF (medial longitudinal fasciculus) in the pontine tegmentum.
