155 Oscillopsia and Bilateral Vestibular Loss with Gentamicin OtotoxicityPatients with bilateral vestibular loss commonly experience oscillopsia with head movements, or an inability to stabilize retinal images with subsequent bouncing or jumping of the environment due to loss of vestibular function.

Examination demonstrated vertical supranuclear gaze palsy (i.e., it could be overcome by the vertical vestibulo-ocular reflex [VOR]), s...Image/MovingImage
159 Palato-ocular Synchrony in Oculopalatal TremorThis is a patient with OPT due to a pontine hemorrhage, and although she did have torsional pendular nystagmus, it was very subtle. However, with eyelid closure, much larger vertical ocular oscillations could be seen, which were in fact synchronous with her palatal tremor. This finding, sometimes ...Image/MovingImage
160 Paraflocculus (Tonsillar) Ocular Motor Syndrome and Dysmetria in a Chiari Malformation - Pre and Post-Operative Exams𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 25-year-old woman presenting with 6 months or progressive imbalance, binocular vertical diplopia, and occipital headaches, which were brought on or aggravated by coughing or sneezing. Examination demonstrated hy...Image/MovingImage
161 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
162 Parinaud's Syndrome in a Man with GBM of the Pineal Gland𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 60-yo-man who presented with diplopia, headaches, and difficulty looking up, and was found to have a mass involving the pineal gland. Biopsy was diagnostic of a GBM. Major features of Parinaud's (dorsal midbrain...Image/MovingImage
163 Parinaud's Syndrome with Impaired Upward Saccades and Otherwise Normal Vertical Eye MovementsThis is a 50-yo-man who suffered a dorsal midbrain stroke. Exam demonstrated normal vertical range of eye movements, normal vertical VOR and smooth pursuit, but inability to perform upward saccades. Another feature of Parinaud's syndrome seen on his exam was light-near dissociation (not shown in thi...Image/MovingImage
164 Paroxysmal Ocular Tilt Reaction𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 60-year-old woman who 2 years prior experienced a left sided hypertensive hemorrhagic stroke, resulting in right hemiparesis, dysarthria and vertical diplopia. The initial vertical diplopia resolved completely a...Image/MovingImage
165 Pendular Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is an example of pendular nystagmus, where like jerk nystagmus, the slow phase initiates the movement. However, unlike jerk nystagmus, there is no fast phase, but rather back to back slow phases resembling a pendulum...Image/MovingImage
166 Pendular Nystagmus and Ocular Motor Signs in MS𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 30-year-old man with a 15 year history of multiple sclerosis. For the last 12 months, he experienced horizontal oscillopsia. On examination, there were ocular motor abnormalities including gaze-evoked nystagmus,...Image/MovingImage
167 Pendular Nystagmus and Vision LossThree patients are presented here, each with poor vision (counting fingers or worse) related to retinitis pigmentosa in one patient (Usher's syndrome) and optic neuropathy in two patients, each of whom developed pendular nystagmus after vision loss developed. Visually mediated movements normally pre...Image/MovingImage

She also had horiz...Image/MovingImage
169 Penlight Cover Test (Partial Removal of Fixation)Penlight cover test (partial removal of fixation): during in-person clinical encounters, the maneuvers below are best tested with complete (or near complete) removal of fixation (e.g., Frenzel or video Frenzel goggles). Removal of fixation is more challenging during virtual evaluations but can be ap...Image/MovingImage
170 Periodic Alternating Nystagmus Due to Nodulus StrokeThis is a 70-year-old woman who experienced the acute onset of vertigo and imbalance. MRI demonstrated a diffusion-weighted imaging hyperintensity involving the nodulus (with corresponding ADC hypointensity) consistent with an acute stroke. On examination several weeks after the stroke, periodic alt...Image/MovingImage
