She was initially diagnosed with posterior canal (PC) benign paroxysmal posit...Image/MovingImage
27 Paraneoplastic Downbeat Nystagmus and Cerebellar Ataxia Due to Small Cell Lung Carcinoma𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 61-year-old woman (non-smoker) who developed a gait disorder, dizziness and oscillopsia that was progressive over 2 months. Exam demonstrated spontaneous downbeat nystagmus with side pocket nystagmus in lateral ...Image/MovingImage
28 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
29 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
30 Alternating Hypertropias - Bilateral 4th Nerve Palsies and Alternating Skew Deviation𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Seen here are two patients with alternating hypertropias. The first is a 70-year-old woman with a diagnosis of cerebellar ataxia, neuropathy, vestibular areflexia syndrome (CANVAS). In the video, both spontaneous downbeat...Image/MovingImage
31 Pendular, Gaze-Evoked and Abducting Nystagmus in MSThis is a 40-year-old woman with a history of multiple sclerosis who presented for oscillopsia. On examination, she had bilateral internuclear ophthalmoplegia (INO-adduction lag OU and abducting nystagmus OU), with a corresponding exotropia that increased in right and left gaze. She also had horiz...Image/MovingImage
32 Ocular Motor Signs in SCA 6𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 45-yo-man who was recently diagnosed with SCA 6. There was no clear spontaneous downbeat nystagmus (DBN) in primary gaze, although DBN could clearly be provoked by convergence. Other ocular motor features includ...Image/MovingImage
33 Cerebellar Eye Signs in SCA8𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 30-yo-man with a diagnosis of SCA 8 who had appendicular and gait ataxia in addition to choppy smooth pursuit and VORS, downbeat nystagmus, saccadic hypermetria, and gaze-evoked nystagmus with rebound nystagmus....Image/MovingImage
34 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
35 The Acute Vestibular Syndrome with Skew Deviation, Gaze-evoked Nystagmus, and Bilaterally Abnormal Head Impulse Testing Due to AICA StrokeThis is a 60-year-old man with the acute onset of prolonged vertigo and nystagmus, consistent with the acute vestibular syndrome (AVS). HINTS (Head Impulse, Nystagmus, Test of Skew) exam demonstrated a central pattern: 1) Head impulse test (HIT) was abnormal to the right and to the left. An abnormal...Image/MovingImage
36 Abnormal Visually-Enhanced VOR in Cerebellar Ataxia, Neuropathy, Vestibular Areflexia Syndrome (CANVAS)A 67 year old woman presented with 1 year of progressive numbness, gait instability, and oscillopsia when walking or with head movements. Examination showed excessive square-wave jerks, bilateral horizontal gaze-evoked nystagmus, impairment of the visually-enhanced vestibular ocular reflex (vVOR - s...Image/MovingImage
