110 Peripheral (Vestibular) and Central (Gaze-Evoked) Patterns of Nystagmus in a Single PatientA 55-year-old man experienced episodic vertigo and was diagnosed with Meniere's disease affecting the left ear (based on audiograms and his clinical course) about 1 year prior to presentation. About 6 months prior to presentation, intratympanic (IT) gentamicin was injected into the left ear, at whic...Image/MovingImage
111 Physiologic End Point NystagmusThis is a normal subject with end point nystagmus in lateral gaze. Features that favor physiologic (normal) end point nystagmus (EPN) rather than pathologic gaze-evoked nystagmus include: only present in far lateral gaze (at close to 100% of the normal range of ocular movements); resolves when the v...Image/MovingImage
112 Pontine Hemorrhage Causing Oculopalatal Tremor and Multiple Cranial NeuropathiesThis is a 45-yo-woman who had a dorsal pontine cavernoma that bled 2 years prior to this video. Symptoms included diplopia and oscillopsia. On examination, she had left>right facial palsies (upper and lower face from involvement of the nucleus/fascicle - i.e., lower motor neuron palsies) and sixth n...Image/MovingImage
113 Positional Downbeat Nystagmus Mimicking Anterior Canal BPPVAlthough positional downbeat nystagmus (pDBN) can indicate the rare anterior canal variant of benign paroxysmal positional vertigo, central mimics are common causes of pDBN. pDBN may be seen in multiple system atrophy (MSA), or seen with posterior fossa lesions, with a common example being a stroke ...Image/MovingImage
114 Positional Nystagmus During an Attack of Vestibular Migraine𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: A 50-year-old woman presented to clinic after experiencing multiple episodes of hours-long vertigo attacks that were associated with headache, photophobia and phonophobia. She had a history of motion sickness and migraine...Image/MovingImage
115 Posterior Canal BPPV Pre- and Post-Epley Maneuver𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a patient with typical right posterior canal benign paroxysmal positional vertigo (BPPV), which was provoked by the Dix-Hallpike maneuver. When the patient was moved into the right Dix-Hallpike maneuver, after a b...Image/MovingImage
116 Posterior Canal BPPV Treated with Semont ManeuverThis is a patient with left posterior canal (PC) benign paroxysmal positional vertigo (BPPV), and upbeat-torsional (towards the left ear) nystagmus was provoked by left Dix-Hallpike maneuver and left side-lying maneuver. This video demonstrates treatment of her left PC BPPV with the Semont maneuver....Image/MovingImage
117 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
118 Provocative Maneuvers (Removal of Fixation, Vibration, Head-Shaking) to Accentuate Peripheral Vestibular Nystagmus)𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: With an acute destructive process like vestibular neuritis that causes significant unilateral vestibular loss, spontaneous nystagmus is always present. However, over days to months, spontaneous nystagmus should resolve co...Image/MovingImage

122 Reversal of Vertical Nystagmus with Convergence in Anti-DPPX Encephalitis𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a man who initially presented with spontaneous upbeat and torsional nystagmus, which led to the diagnosis of anti-DPPX encephalitis (for further details on this patient's course and for a video of his nystagmus, s...Image/MovingImage
123 Right Dix Hallpike TestThe Dix-Hallpike tests for benign paroxysmal positional vertigo (BPPV). A test is positive when a patient reports vertigo, dizziness, or sensation of movement or falling with nystagmus present. When the head is in this position, it allows the posterior canal to be aligned with the gravitational vect...Text
124 Right Dix Hallpike Test (Video)The Dix-Hallpike tests for benign paroxysmal positional vertigo (BPPV). A test is positive when a patient reports vertigo, dizziness, or sensation of movement or falling with nystagmus present.
