27 Saccades𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: The examiner should note: conjugacy (a lag of the adducting eye may be seen with an INO); accuracy (posterior fossa lesions commonly produce dysmetria (overshooting or undershooting); velocity (if slow, may suggest a lesi...Image/MovingImage
28 Range of Eye Movements and Evaluation for Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Range: Assesses for motility deficit due to an ocular motor palsy, particularly if a posterior fossa localization is being considered; Nystagmus: Spontaneous nystagmus may or may not be noted and gaze-evoked nystagmus is ...Image/MovingImage
29 Smooth Pursuit𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: A pursuit deficit in one direction suggests an ipsilesional localization, but beware of a superimposed spontaneous nystagmus; a pursuit deficit in all directions is commonly seen with cerebellar lesions. 𝗡𝗲𝘂𝗿�...Image/MovingImage

32 3rd Nerve Palsy With Preserved 4th Nerve Function80-yo-woman with a left vasculopathic 3rd nerve palsy (minimal pupil involvement of about 1 mm relative mydriasis OS - other etiologies ruled out and resolved as expected over months). Although the inferior rectus is paretic, intact superior oblique muscle function can be demonstrated by asking the ...Image/MovingImage
33 The Acute Vestibular Syndrome in MS Due to Middle Cerebellar Peduncle/Root Entry Zone LesionThis is a 13 year-old girl with relatively abrupt onset vertigo and oscillopsia. On exam, there was primarily right-beating nystagmus in primary gaze with a slight upward (upbeat) component, giving the nystagmus an oblique appearance. The upward component and lack of a clear torsional component acut...Image/MovingImage
34 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...Image/MovingImage
35 Complete Peripheral Vestibulopathy & Ipsilateral Facial Palsy𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: 60-yo-man who suffered the fairly abrupt onset (over hours) of right lower motor neuron facial nerve palsy (7th cranial nerve), vertigo and deafness in the right ear (8th cranial nerve). Vesicles were noted on otoscopy, a...Image/MovingImage
36 Latent Nystagmus and DVD in Infantile EsotropiaThis is a 20-year-old woman with infantile esotropia (s/p strabismus surgery as a child) who demonstrated latent nystagmus and presumed dissociated vertical deviation (DVD) OS, which are commonly seen with infantile esotropia (also inferior oblique overaction and monocular nasotemporal asymmetry to ...Image/MovingImage
37 Medial Medullary SyndromesThis is a video of two patients who suffered small strokes involving the right medial medulla, and who presented with acute vertigo and oscillopsia. The first patient in the video had pure upbeat nystagmus, while the second patient had upbeat-torsional (towards the right ear) nystagmus in addition t...Image/MovingImage
38 Posterior Canal BPPV with Fixation and with Fixation RemovedThis is a 60-yo-woman with positional vertigo. In the right Dix-Hallpike position with fixation removed, there was clear upbeat-torsional nystagmus (towards the lowermost right ear) which led to the diagnosis of right posterior canal BPPV. In right Dix-Hallpike with fixation there was mainly torsion...Image/MovingImage
39 Unidirectional Nystagmus in Lateral Medullary SyndromeThis is a 70-yo-man who presented with acute vertigo. Examination demonstrated very mild spontaneous torsional nystagmus (towards the right ear) in primary (not seen well in this video), with robust downbeat-torsional (towards right ear) nystagmus in right gaze and (less robust) almost pure torsiona...Image/MovingImage
40 Unidirectional Vestibular Nystagmus60-yo-man with recurrent vertigo attacks - this video was taken during one of his typical attacks, and shows left-beating nystagmus that stayed left-beating in all directions of gaze, more in left gaze (in accordance with Alexander's Law), and less in right gaze. This pattern is more commonly seen w...Image/MovingImage
41 Wallenberg Syndrome in MS𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: 30-yo-woman with MS presenting with acute vertigo and vertical diplopia. Examination demonstrated several aspects of the Wallenberg syndrome (her acute demyelinating lesion was in the left lateral medulla): ipsilesional (...Image/MovingImage
42 Downbeat Nystagmus and Convergence SpasmThis is a 60-yo-woman with vertical oscillopsia related to her downbeat nystagmus, and diplopia related to an intermittent esotropia. When the esotropia was present, with versions there were bilateral abduction deficits. With ductions and the vestibulo-ocular reflex, it was apparent that the range o...Image/MovingImage
43 Idiopathic Downbeat Nystagmus, Decreasing with ConvergenceThis is a 25-yo-woman who experienced vertically oscillopsia for 1 year, and was found to have downbeat nystagmus. Interestingly, there were no other cerebellar ocular motor signs - e.g., normal saccades, smooth pursuit, VOR suppression, and no gaze-evoked nystagmus, although her (pure) downbeat was...Image/MovingImage
44 Cerebellar Degeneration with Downbeat Nystagmus Provoked by ConvergenceDescription: This is a 70-yo-woman with a progressive gait disorder, diagnosed with cerebellar ataxia. She displayed typical cerebellar ocular motor signs including gaze-evoked nystagmus, choppy pursuit and VOR suppression, and there was very subtle spontaneous downbeat nystagmus, best appreciated w...Image/MovingImage
45 Traumatic 3rd Nerve Palsy with Aberrant Regeneration𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 20-yo-woman who experienced severe head trauma and diplopia upon awakening from a coma several weeks after the injury.

46 Aberrant Regeneration of the 3rd NerveAberrant regeneration in two patients: 1) a young woman with a right cavernous sinus meningioma with subsequent development of aberrant regeneration demonstrated by eyelid elevation OD in attempted downgaze (i.e., some fibers that were supposed to innervate the right IR were misrouted to the right l...Image/MovingImage
47 Elliptical Pendular Nystagmus in MS𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 40-yo-woman with MS and bilateral optic nerve disease who presented with a year's long history of oscillopsia, which was related to elliptical pendular nystagmus. The appearance of elliptical nystagmus is the re...Image/MovingImage

50 Vertical-Torsional Pendular Nystagmus and Convergence Spasm Due to Anti-MaTa EncephalitisThis is a 50-yo-woman with debilitating oscillopsia due to a high frequency (6 Hz) vertical-torsional pendular (quantitative eye movement recordings were performed) nystagmus. She also had intermittent double vision due to (organic) convergence spasm. Her nystagmus and spasm were thought to be relat...Image/MovingImage
