1 Parinaud's syndrome in a man with GBM of the pineal glandThis 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) syndrome were present including: upgaze palsy, convergence retraction
2 Apraclonidine testing in Horner's syndromeThis patient experienced relatively abrupt ptosis and was seen and diagnosed with a Horner's syndrome within a few days of the onset. There were no other exam findings and history did not offer clues as to the etiology. Neuroimaging of the oculosympathetic tract was unrevealing. Apraclonidine
3 Congenital nystagmusPresented here are two patients with congenital nystagmus demonstrating characteristic features including: mixed pendular and jerk nystagmus (usually gaze-evoked) waveforms, stays horizontal even in vertical gaze, suppression with convergence, strabismus and a latent component (common but not
4 Monocular horizontal pendular nystagmus in MSBoth of these patients have MS and monocular (OS) horizontal pendular nystagmus. The first patient seen in the video has normal afferent function and no evidence of optic nerve disease in either eye, while the second patient has severe OS>>OD optic nerve disease related to bouts of optic neuritis (
5 Post-infectious ocular flutter and myoclonus syndromeThis is a 35-yo-woman presenting with oscillopsia following a viral illness. She described being easily startled, with "shakiness" of the head/neck and body. She had myoclonus and ocular flutter, with the latter evident when she initiated saccades. Eye movement recordings showed that most of her
6 Periodic alternating nystagmus and perverted head-shaking nystagmus in cerebellar degenerationThis is a 60-yo-woman with several years of worsening imbalance, diplopia (hers was actually unrelated to cerebellar pathology [although she did have an esotropia greater at distance that was cerebellar in origin] and due to thyroid eye disease) and blurry vision (due to her spontaneous nystagmus).
7 Voluntary Ocular FlutterThis is a 45-yo-man with intermittent complaints of horizontal oscillopsia for 1 year. On examination, all classes of eye movements were normal, and neurologic examination was normal. MRI of the brain had been performed previously and was normal. During the exam while viewing any target close to
8 Superior Oblique Myokymia (SOM)This is a patient with transient monocular oscillopsia OD and vertical diplopia noted to have many episodes of SOM in the office. There was not only myokymia OD, but also a 4 prism diopter left hypertropia during episodes (suggestive of mild depression OD from SO activation). Ocular motor and
9 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
10 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
11 Idiopathic downbeat nystagmus exacerbated with positional maneuvers - Part 2: patient is now on 4-aminopyridineThis is a 45-yo-woman presented in "Idiopathic downbeat nystagmus exacerbated with positional maneuvers". This video was taken after the patient had been on 4-aminopyridine for 3 months. There was marked improvement in subjective oscillopsia and objective downbeat nystagmus. The strong positional
12 Unidirectional nystagmus in lateral medullary syndromeThis is a 70-yo-man who presented with acute vertigo. Examination demonstrated very mild spontaneous torsional nystagmus (towards the right ear) in primary (not seen well in this video), with robust downbeat-torsional (towards right ear) nystagmus in right gaze and (less robust) almost pure
13 Medial medullary syndromesThis is a video of two patients who suffered small strokes involving the right medial medulla, and who presented with acute vertigo and oscillopsia. The first patient in the video had pure upbeat nystagmus, while the second patient had upbeat-torsional (towards the right ear) nystagmus in addition
14 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
15 Typical lid signs (Cogan's lid twitch, lid hopping, enhanced ptosis) in myasthenia gravisThis 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 of equal innervation to the two levator
16 Prolonged lid twitch in myasthenia gravisThis 50-yo-woman with ocular MG demonstrated a spontaneous and particularly prolonged eyelid
17 Sequelae of cerebellar hemorrhage - gaze-evoked nystagmus, alternating skew deviation and palatal tremorThis is a 75-yo-woman presenting with a gait disorder. Two years prior, she suffered a cerebellar hemorrhage. On examination, there were typical cerebellar ocular motor signs including gaze-evoked nystagmus, choppy smooth pursuit and VOR suppression, and saccadic dysmetria. There was also an
18 Rebound nystagmusThis is a 50-yo-man who presented for dizziness and imbalance. His exam demonstrated choppy smooth pursuit and VOR suppression as well as mild gait ataxia. There was mild right-beating nystagmus in right gaze and left-beating nystagmus in left gaze without vertical gaze-evoked nystagmus.
19 Eye signs in infantile esotropia - latent nystagmus and inferior oblique overactionThis is a 25-yo-man with a history of amblyopia and intermittent eye crossing. On exam, he had a comitant 25 prism diopter esotropia, and other features of infantile (or congenital) esotropia including: latent nystagmus (right-beating nystagmus with occlusion of the left eye and left-beating
20 Horner's syndrome with anhidrosisThis is a patient with the onset of ptosis OD years prior, with clear evidence of a Horner's syndrome. Imaging of the oculosympathetic tract was unrevealing. The patient also mentioned that with exercise, the left side of her face will sweat and turn red while the right side wouldn't. She took a
21 Traumatic 3rd nerve palsy with aberrant regenerationThis is a 20-yo-woman who experienced severe head trauma and diplopia upon awakening from a coma several weeks after the injury. She had a partial left 3rd nerve palsy (adduction spared), and when she looked to the right and down, her mildly ptotic lid elevated. Aberrant regeneration of CN 3 occurs
22 Wallenberg syndrome in MS30-yo-woman with MS presenting with acute vertigo and vertical diplopia. Examination demonstrated several aspects of the Wallenberg syndrome (her acute demyelinating lesion was in the left lateral medulla): ipsilesional (left) ocular lateropulsion (hypermetric saccades to the left, hypo to the
23 Inferior oblique overaction in a congenital 4th nerve palsy60-yo-man complaining of intermittent oblique diplopia. There was a left hypertropia that worsened in down gaze, right gaze and in left head tilt. There was a large vertical fusional amplitude in addition to a longstanding rightward head tilt, and on examination there was left inferior oblique
24 Sequential vasculopathic 3rd nerve palsies with preserved 4th nerve function65-yo-man with uncontrolled diabetes who developed sequential vasculopathic 3rd nerve palsies. In attempted downgaze, there's clear incyclotorsion OU suggestive of preserved 4th nerve function on both sides. There was complete recovery over months. Video shows bilateral 3rd nerve palsies with
25 Unidirectional vestibular nystagmus60-yo-man with recurrent vertigo attacks - this video was taken during one of his typical attacks, and shows left-beating nystagmus that stayed left-beating in all directions of gaze, more in left gaze (in accordance with Alexander's Law), and less in right gaze. This pattern is more commonly seen
