Over time, he developed bilateral adduction paresis, ptosis and upgaze paresis ...Image/MovingImage
259 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
260 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
261 One-and-a-Half Syndrome, Facial Palsy, and Nystagmus Due to Dorsal Pontine DemyelinationThis is a 16-yo-girl with oscillopsia and double vision. Exam showed inability to look to the left with either eye due to left nuclear 6th. There was also a left INO (horizontal gaze palsy + INO = one-and-a-half syndrome) from left MLF involvement and left lower motor neuron facial palsy due to fasc...Image/MovingImage
262 Two Patients with Parinaud's Syndrome with Slow Upward Saccades and Normal Upward Range of MovementsPresented here are two patients with Parinaud's syndrome: Patient 1) suffered a hemorrhage of the dorsal midbrain causing slow upward saccades (with convergence retraction nystagmus, but normal vertical range of eye movements), and light-near dissociation, and Patient 2) had a germinoma of the dorsa...Image/MovingImage
263 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
264 Central Positional Vertigo and Nystagmus in a Posterior Fossa Tumor𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 30-year old woman who presented with positional vertigo and vomiting following a concussion related to a car accident 3 months prior. She was initially diagnosed with posterior canal (PC) benign paroxysmal posit...Image/MovingImage
265 Downbeat Nystagmus with Active Horizontal Head ShakingThis is a 70-year-old man who presented with one single complaint for 10 years - if he moved his head too quickly (even one single horizontal head movement to the right or the left), he would experience the abrupt loss of balance and dizziness. His typical episodes were reproducible, and interesting...Image/MovingImage
266 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

Seen in this video are common ocular motor signs in patients with advanced cerebellar dysfunction inc...Image/MovingImage
269 Slow Horizontal, Vertical and Oblique Saccades in Spinocerebellar Ataxia Type IThis is a patient presenting with horizontal diplopia who was found to have divergence insufficiency, an esotropia greater at distance than near in the absence of abduction paresis.

272 Central (Nuclear) 3rd Nerve PalsiesShown here are two patients with left sided midbrain pathology (hemorrhage and ischemia) which caused damage to the 3rd nucleus.

273 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
274 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
