51 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
52 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
53 Cerebellar Degeneration with Downbeat Nystagmus Provoked by ConvergenceDescription: This is a 70-yo-woman with a progressive gait disorder, diagnosed with cerebellar ataxia.

59 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
60 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
61 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
62 Enhanced Ptosis in Myasthenia GravisThis is a 20-yo-woman who presented with generalized weakness, ptosis and ophthalmoplegia. She had severe ptosis OU at baseline, but when one eyelid was manually elevated, there was marked enhanced ptosis of the opposite eyelid. This was in accordance with Hering's law of equal innervation of the le...Image/MovingImage
63 Miller Fisher Syndrome - Ophthalmoplegia and Hyperreflexia𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 45-yo-woman who presented with mild imbalance and diplopia. There had been a preceding viral illness several weeks prior. Examination demonstrated horizontal gaze paresis (sparing unilateral adduction), mild gai...Image/MovingImage
64 Miller Fisher Syndrome - Ophthalmoplegia, Ptosis and Ataxia𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a young man who presented with ptosis, difficulty moving the eyes and gait imbalance several weeks after a GI illness. Miller Fisher syndrome was diagnosed, IVIG therapy was initiated, and anti-Gq1b antibodies cam...Image/MovingImage
65 Typical Lid Signs (Cogan's Lid Twitch, Lid Hopping, Enhanced Ptosis) in Myasthenia Gravis𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 60-yo-woman with MG who displays typical eyelid signs including Cogan's lid twitch, lid hopping (appreciated during horizontal smooth pursuit in this patient), and enhanced ptosis in accordance with Hering's law...Image/MovingImage
66 Prolonged Lid Twitch in Myasthenia GravisThis 50-yo-woman with ocular MG demonstrated a spontaneous and particularly prolonged eyelid twitch.Image/MovingImage
67 Wall-eyed Bilateral INO in Caudal Midbrain LesionThis is a 30-yo-woman with the relatively acute onset of diplopia. There was a large angle exotropia, very subtle lag of the adducting saccades OD>OS, suggestive of bilateral INOs. This was best seen with rapid horizontal saccades, and a lesion involving bilateral MLFs in the caudal midbrain was dem...Image/MovingImage
68 Pseudo-INOs in Myasthenia GravisThis is a 55-yo-woman with an intermittent exotropia who had normal adduction OU, but clear lag of adducting saccades OD>OS with rapid horizontal saccades. This was much more apparent after repeat testing (ie, it was fatigable), and she wound up having ocular MG.Image/MovingImage
69 One-and-a-Half Syndrome, Facial Palsy, and Nystagmus Due to Dorsal Pontine DemyelinationThis is a 16-yo-girl with oscillopsia and double vision.

72 Torsional Jerk NystagmusPresented here are 3 patients with torsional jerk nystagmus. The first patient presented with vertigo and experienced oscillopsia due to her torsional nystagmus. Pure or predominantly torsional nystagmus is highly suggestive of a central process. Her nystagmus was unidirectional and followed Alexand...Image/MovingImage
