76 Evaluation of Auditory Function Using Rinne and Weber Tests𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: The Rinne test is an assessment of auditory thresholds to air and bone conduction of sound. The Weber test is a comparison of bone conducted sound of either ear. Conductive hearing loss results in a loss of air conducte...Image/MovingImage
77 Evaluation of Convergence𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: The assessment of convergence includes measuring alignment at near versus distance (see video, https://collections.lib.utah.edu/details?id=187677), near point of convergence and convergence amplitude. Near point of conve...Image/MovingImage
78 Examples of Patients with Saccadic Intrusions (Square Wave Jerks)Seen here are patients with saccadic intrusions that do have an intersaccadic interval. Square wave jerks are commonly seen in degenerative conditions, mainly involving the posterior fossa (e.g., cerebellar degeneration) and basal ganglia (e.g., progressive supranuclear palsy).Image/MovingImage

82 Eyelid NystagmusLid nystagmus is a rhythmic eyelid movement commonly seen as an epiphenomenon of vertical nystagmus (typically upbeating, as in this case) due to a shared central pathway controlling elevation of the lid and supraduction. There can be isolated lid nystagmus if there is accompanying impairment of su...Image/MovingImage
83 Five Common Ocular Motor Signs in Cerebellar Disorders - Saccadic Hypermetria, Saccadic Pursuit & VOR Suppression, Gaze-evoked & Rebound Nystagmus(1) Saccadic hypermetria - an overshoot of the visual target (2) Saccadic smooth pursuit - due to impaired pursuit and low gain, saccades are needed to keep up with the visual target. This gives it a ‘choppy' appearance. (3) Saccadic vestibulo-ocular reflex (VOR) suppression - another...Image/MovingImage
84 Fixation and Gaze HoldingFixation and gaze-holding: assess for nystagmus or saccadic intrusions by observing the eyes in primary position. Then instruct the patient to look in each position of gaze, and to hold that position to assess for gaze-evoked nystagmus. In doing so, motility can also be evaluated with both eyes view...Image/MovingImage
85 Gaze-Evoked Nystagmus & Slow Saccades Due to Anti-GAD Antibodies in a Patient with Stiff Person SyndromeThis is a 70-year-old woman with a several year long history of imbalance and stiffness. Exam demonstrated axial and lower extremity stiffness, and ocular motor exam demonstrated gaze-evoked nystagmus (e.g., right-beating in right gaze, left-beating in left gaze, up-beating in up gaze), and mild to ...Image/MovingImage
86 Gaze-Evoked and Centripetal Nystagmus in Creutzfeldt-Jakob DiseaseThis is a 65-year-old woman who experienced a progressive cerebellopathy over several months. Initially, she presented with mild gait imbalance and positional vertigo, and there was only apogeotropic positional nystagmus (more pronounced in supine roll test compared to Dix-Hallpike) with a very slig...Image/MovingImage
87 Gaze-Evoked, Rebound, and Centripetal Nystagmus in Cerebellar DegenerationA 68-year-old female reported a 2-year history of progressive gait imbalance, falls, dizziness and vertical oscillopsia. She described that dizziness and oscillopsia were worst when looking down. There was no family history of ataxia. Composite gaze with fixation was recorded with video-oculography ...Image/MovingImage
88 Gaze-evoked and Rebound Nystagmus in a Cerebellar Syndrome𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: 30-yo-man with the subacute onset of a cerebellar syndrome. After extensive evaluation and progression, it was thought that this represented an autoimmune process and there was some improvement with immunosuppression. He ...Image/MovingImage
89 Gufoni Maneuver for Left Horizontal Canal BPPV, Canalithiasis (Geotropic Nystagmus) (Video)The Gufoni maneuver may be preferable to the BBQ roll, as the Gufoni maneuver does not require the individual to roll or be in a prone position, making the maneuver more feasible to complete for individuals who are elderly, obese and/or experience immobility. Antecedently, some clinicians remember t...Image/MovingImage
90 Gufoni Maneuver for Right Horizontal Canal-Cupulolithiasis (Apgeotropic Nystagmus) (Video)The Gufoni Maneuver can be used to treat horizontal canal cupulolithaisis. 1. The patient starts in a seated position. 2. The patient transitions quickly to lying on their affected side. 3. The patient lies on their affected side for two minutes with the head in a neutral position. 4. The patient's ...Image/MovingImage
91 HINTS Exam and Saccadic Dysmetria in Lateral Medullary Stroke𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 50-year-old who experienced the abrupt onset of prolonged vertigo following chiropractic therapy 2 months prior.

93 Head-Shaking (2-3 Hz)Head-shaking: instruct the patient to close their eyes and perform active rapid head-shaking at 2-3 Hz for ~15 secs. If a unilateral vestibulopathy is present, head-shaking-induced (contralesional) nystagmus is often provoked, with the slow phase toward the affected ear. With central lesions, the ny...Image/MovingImage
94 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
95 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.
