51 | Two Patients with Parinaud's Syndrome with Slow Upward Saccades and Normal Upward Range of Movements | Presented 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... | Abnormal Saccades; Dorsal Midbrain; Jerk Nystagmus; Gaze Evoked Nystagmus | |
52 | Unilateral 3rd, 4th, and 6th Nerve Palsies Due to Cavernous Sinus Meningioma | 𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is a 50-year-old woman presenting with a partial 3rd nerve palsy (mild pupil involvement), partial 6th nerve palsy, and no clear incyclotorsion with downgaze, suggestive of additional 4th nerve palsy, all on the left... | Abnormal Range; Third Nerve Palsy; Aberrant Regeneration; Fourth Nerve Palsy; Sixth Nerve Palsy; Jerk Nystagmus; Downbeat Nystagmus; Gaze Evoked Nystagmus; Abnormal Saccades | |
53 | Upbeat Nystagmus & Ocular Flutter Due to Cerebellar Pilocytic Astrocytoma | This is a 20-year-old woman who was diagnosed with a cerebellar pilocytic astrocytoma at age 10 after presenting with severe headaches and hydrocephalus. She underwent incomplete resection and radiation therapy at that time. She experienced mild vertical oscillopsia in upgaze at baseline, and increa... | Upbeat Nystagmus; Ocular Flutter | |
54 | Upbeat and Downbeat Nystagmus Due to Anti-VGCC Antibodies | Seen here are two patients who presented with imbalance and vertical oscillopsia, the first with upbeat nystagmus, and the second with downbeat nystagmus. Both patients were found to have voltage-gated calcium channel antibodies in serum without evidence of systemic malignancy. The UBN patient had m... | Jerk Nystagmus; Upbeat Nystagmus; Gaze Evoked Nystagmus; Downbeat Nystagmus | |
55 | Upbeating and Gaze-evoked Nystagmus, V-pattern Esotropia from Bilateral 4th Nerve Palsies | Video example of a patient with upbeating and gaze-evoked nystagmus, V-pattern esotropia from bilateral 4th nerve palsies. | Upbeat Nystagmus; Gaze Evoked Nystagmus; Fourth Nerve Palsy | |
56 | Wall-eyed Bilateral INO in Caudal Midbrain Lesion | This 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... | INO; Abnormal Saccades; Jerk Nystagmus; Gaze Evoked Nystagmus |
