255 Slow Volitional Saccades and Poor Fast Phases to an Optokinetic Stimulus, with Preserved Head Impulse TestingThis is a 67-year-old woman presenting with imbalance and binocular horizontal diplopia at near. On examination there were frequent square wave jerks, limited supraduction OU and convergence insufficiency, which explained her diplopia. Pursuit and suppression of the vestibulo-ocular reflex were sa...Image/MovingImage
256 VOR (Slow and Fast)𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Slow vestibulo-ocular reflex (VOR): Since smooth pursuit and VOR systems are both active, if eye movements are choppy with this maneuver this implies deficits in both pursuit and the vestibular system as in CANVAS; Fast (...Image/MovingImage
257 Head-Shaking Nystagmus - A 'Central' Pattern𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Evaluating for nystagmus provoked by head-shaking, so-called head-shaking nystagmus (HSN), should be performed in all patients with complaints of dizziness or vertigo, regardless of the chronicity.

He was found to have herpetic vesicles in the left external auditory canal...Image/MovingImage
260 Downbeat (Perverted) Head Shaking Nystagmus in a Patient with Spontaneous Torsional Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 75-year-old woman with vascular risk factors who experienced abrupt onset imbalance and dizziness. Symptoms were maximal at onset, and she denied progression over 6 months. Clinically, it was felt that she had s...Image/MovingImage
261 Superior Canal Dehiscence𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 60-yo-man who complained of autophony (eg, hearing his own heartbeat, noting that his own voice sounded too loud) and dizziness triggered with loud noises and straining at times. With pinched-nose Valsalva maneu...Image/MovingImage
262 Pressure Testing for Superior Canal Dehiscence Syndrome𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Superior semicircular canal dehiscence syndrome (SCDS) is caused by a third mobile window in the inner ear. This allows for transmission of sound or pressure to the superior canal. Tragal compression and/or glottic and ...Image/MovingImage
263 Pinched Nose ValsalvaValsalva (closed glottis or pinched nose): instruct the patient to take a deep breath and ‘bear down' (closed glottis) or take a deep breath and ‘try to pop their ears' (pinched nose). Assess for nystagmus. In superior canal dehiscence, pressure changes may be transmitted to the superior canal, ...Image/MovingImage
264 Head-Shaking NystagmusHead-shaking nystagmus: With a peripheral lesion, similar to vibration, transiently accentuates vestibular asymmetry when baseline VOR function is asymmetric, central patterns are well described and have localizing value (e.g., causing vertical nystagmus after horizontal head-shaking, horizontal nys...Image/MovingImage
265 VibrationVibration: instruct the patient to self-administer this test with an electric toothbrush or vibrator/massager, if available. Vibration of the mastoids and vertex will induce an ipsilesional slow phase with unilateral vestibular loss (https://collections.lib.utah.edu/details?id=1427582).Image/MovingImage
266 Pseudo-Spontaneous Nystagmus and Bow and Lean Test in Horizontal Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻:This is a 70-year-old woman presenting to the Emergency Department with positional vertigo that was determined to be due to the apogeotropic variant of right horizontal canal (HC) benign paroxysmal positional vertigo (BPPV...Image/MovingImage
267 The Geotropic Variant of Horizontal Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a patient with the geotropic (nystagmus beating towards the ground) variant of left horizontal canal (HC) benign paroxysmal positional vertigo (BPPV). In a patient with geotropic (nystagmus beating towards the gro...Image/MovingImage
268 The Apogeotropic Variant of Horizontal Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a patient with the apogeotropic (nystagmus beating towards the sky) variant of right horizontal canal (HC) benign paroxysmal positional vertigo (BPPV). In a patient with geotropic (nystagmus beating towards the gr...Image/MovingImage
269 Anterior Canal BPPV𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Although the anterior canal (AC) variant of benign paroxysmal positional vertigo (BPPV) is rare, mainly owing to its orientation relative to gravity (which makes otoconial debris much less likely to enter it), it can occu...Image/MovingImage
270 Horizontal Canal - BPPV: Gufoni for Right Apogeotropic𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: To treat the right apogeotropic (beating towards the sky with right ear down and with left ear down - e.g., left beating nystagmus with right supine roll test or with right ear down; right beating nystagmus with left supi...Image/MovingImage
271 Horizontal Canal - BPPV: BBQ Roll to Treat the Right Side𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: To treat right horizontal canal (HC)-BPPV (each position maintained for at least 30 seconds or until nystagmus and/or vertigo cease): • First the patient is placed in the long-sitting position • Then in a supine posit...Image/MovingImage
272 Anterior Canal - BPPV: Deep Head Hanging𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Regardless or whether it is thought that the patient has right or left anterior canal (AC) involvement, the deep head hanging maneuver is performed in the same way. • First the patient is placed in the long-sitting posi...Image/MovingImage
273 Eye Handbook App for OKNOptokinetic nystagmus (OKN): one way this can be examined virtually is using a smartphone application (e.g. Eye Handbook © app used in this video) or optokinetic tape/flag/drum held in front of the examiner's camera. The optokinetic stimulus should occupy the full screen of the patient's device (ea...Image/MovingImage
274 Impaired Smooth Pursuit and Other Characteristic Ocular Motor Findings in Middle Cerebellar Peduncle Stroke𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 50-year-old woman who underwent resection of a left-sided acoustic neuroma, and post-operatively, she had vertigo, binocular diplopia, left hemi-ataxia and severe gait ataxia. MR diffusion weighted imaging demon...Image/MovingImage
