1 Bilateral Horizontal Gaze Palsy and Oculopalatal Tremor Due to Pontine HemorrhageThis 70-yo-woman experienced headache and diplopia and was found to have a hemorrhage centrally within the dorsal pons. Months after the onset, the patient was seen in clinic and had no horizontal eye movements (pursuit, saccades, VOR) in either eye, suggestive of bilateral nuclear 6th nerve palsies...VOR HIT Abnormal, Horizontal Gaze Palsy, OMS PONS, Pendular Nystagmus, Oculopalatal
2 Chronic progressive external ophthalmoplegia (CPEO) and cerebellar signsThis is a 60-yo-woman who initially presented with imbalance and ophthalmoparesis. Initially, there was mild horizontal gaze limitation with mild gaze-evoked nystagmus and slow saccades, and over the years, gait ataxia and dysarthria (mainly a scanning quality to her speech) developed, and her ophth...Abnormal Saccades, Abnormal Range, Horizontal Gaze Palsy, Gaze Evoked Nystagmus
3 Horizontal Gaze Palsy, Facial Nerve Palsy, and Nystagmus Due to Dorsal Pontine IschemiaPresented here are two patients with horizontal gaze and facial palsies due to stroke. The first patient is a 60-year-old man who presented with double vision and hemiparesis due to a right dorsal pontine ischemic stroke. His exam was significant for a right horizontal gaze palsy due to right 6th nu...One and half syndome; Horizontal gaze palsy; Pons; Jerk nystagmus; Upbeat nystagmus; Gaze evoked nystagmus; Facial nerve palsy; Internuclear ophthalmoplegia
4 Miller Fisher Syndrome - Ophthalmoplegia and HyperreflexiaThis is a 45-yo-woman who presented with mild imbalance and diplopia. There had been a preceding viral illness several weeks prior. Examination demonstrated horizontal gaze paresis (sparing unilateral adduction), mild gait ataxia (no clear appendicular ataxia), and hyperreflexia. Pupils were sluggis...Range of eye movements/motility abnormal; Horizontal gaze palsy; Miller Fisher Syndrome
5 Oculopalatal tremor with prominent nystagmus, bilateral horizontal gaze palsy, and bilateral facial palsiesThis is a 50-year-old woman who experienced the acute onset of right sixth and seventh nerve palsies and left hemiparesis. Two cavernomas within the right pons (one in the region of the facial colliculus) were demonstrated by MRI. Five years after her initial presentation she developed recurrent r...Abnormal Range, Sixth Nerve Palsy, Facial Nerve, Horizontal Gaze Palsy, OMS Pons, Pendular Nystagmus, Oculopalatal
6 One-and-a-half syndrome, facial palsy, and nystagmus due to dorsal pontine demyelinationThis is a 16-yo-girl with oscillopsia and double vision. Exam showed inability to look to the left with either eye due to left nuclear 6th. There was also a left INO (horizontal gaze palsy + INO = one-and-a-half syndrome) from left MLF involvement and left lower motor neuron facial palsy due to fasc...One-and-a-half syndrome; Horizontal gaze palsy; Pons; Jerk nystagmus; Upbeat nysagmus; Facial nerve palsy; Internuclear ophthalmoplegia
7 Slow saccades due to unilateral paramedian pontine reticular formation (PPRF) injury with preserved movements using the vestibulo-ocular reflexThis is a 60-year-old man who presented for imbalance and oscillopsia 10 months after surgery and 8 months after radiation for Merkel cell carcinoma of the neck. He developed imbalance after surgery and diplopia and oscillopsia 6 months prior to our evaluation. MRI showed enhancement of both 6th n...Abnormal Saccades, Pons OMS, Sixth Abducens Nerve, Abnormal VOR, Vestibulocochlear Nerve, Horizontal Gaze Palsy
