1 Saccades𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: The examiner should note: conjugacy (a lag of the adducting eye may be seen with an INO); accuracy (posterior fossa lesions commonly produce dysmetria (overshooting or undershooting); velocity (if slow, may suggest a lesi...Image/MovingImage
2 Smooth Pursuit𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: A pursuit deficit in one direction suggests an ipsilesional localization, but beware of a superimposed spontaneous nystagmus; a pursuit deficit in all directions is commonly seen with cerebellar lesions. 𝗡𝗲𝘂𝗿�...Image/MovingImage
3 Vertical Gaze Palsy and Saccadic Intrusions Due to Anti-Ri from Head and Neck CarcinomaA 55-yo- woman was admitted for imbalance and double vision. Three weeks prior to presentation she first noticed swelling on the right side of her face and neck. CT of the head and neck showed right-sided cervical adenopathy and enlarged left retropharyngeal node. Ultrasound- guided biopsy of the n...Image/MovingImage
4 Dorsal Midbrain Syndrome from Stroke - Collier's Sign & PseudoabducensThis is a 70-yo-man who suffered a right midline thalamic/rostral midbrain hemorrhagic stroke causing a pretectal (Parinaud's) syndrome.

6 Ocular Alignment𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: These tests allow for detection of eso-, exo- or hyperdeviations (phorias (one eye viewing) or tropias (both eyes viewing) that can be seen with ocular motor palsy, skew deviation, or with cerebellar disease (commonly eso...Image/MovingImage
7 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 alterna...Image/MovingImage
8 Saccadic Intrusions (Square Wave Jerks, SWJ)𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Seen here are SWJ, which is the most common example of a saccadic intrusion. Here the patient is fixating on the camera, and all of the sudden a saccade takes the eyes off the fixation target, there's a brief intersaccadi...Image/MovingImage
9 Divergence Insufficiency in Cerebellar AtaxiaThis is a 65-yo woman with complaints of imbalance (progressive over years) and horizontal diplopia at distance. On her exam, there was a small symptomatic esotropia at distance, but only a small esophoria at near. There were no obvious abduction deficits, and the 6 prism diopter ET at distance was...Image/MovingImage
10 Eye Signs in Infantile Esotropia - Latent Nystagmus and Inferior Oblique Overaction𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This 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 (...Image/MovingImage
11 Head Movement Independent ('Sitting') Oscillopsia - A Common Symptom of Nystagmus and Saccadic Intrusions/Oscillations𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This video is an example of what a patient with spontaneous nystagmus or saccadic intrusions/oscillations experiences visually during the abnormal eye movements - i.e., oscillopsia (illusion of movement of the stationary ...Image/MovingImage
12 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 co...Image/MovingImage
13 INOs in Stroke𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This video shows 3 patients with vascular risk factors who suffered strokes of the MLF resulting in unilateral INO in each case. In the second case, INO was diagnosed status post cardiac catherization and MRI was found to...Image/MovingImage
14 Internuclear Ophthalmoplegia (INO) in Multiple Sclerosis𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This video includes 3 patients each with a known history of MS found to have unilateral or bilateral INOs on their exam. In the first 2 patients, the INOs are relatively subtle with normal adduction. However, with rapid h...Image/MovingImage
15 Jerk Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: This is an example of jerk nystagmus due to a central vestibular lesion. The slow phase is the pathologic phase (to the left) which initiates the movement, and is followed by a fast position reset mechanism (to the right)...Image/MovingImage
16 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
17 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
18 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
19 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. Occasionall...Image/MovingImage
20 ConvergenceCan bring out or change the direction of vertical nystagmus in Wernicke's, or cerebellar disease; may be impaired in Parkinson's disease, head trauma, elderly patients; may overcome an adduction deficit with an INO. Instructional ocular motor examination procedures.Image/MovingImage
21 Range of Eye Movements and Evaluation for Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Range: Assesses for motility deficit due to an ocular motor palsy, particularly if a posterior fossa localization is being considered; Nystagmus: Spontaneous nystagmus may or may not be noted and gaze-evoked nystagmus is ...Image/MovingImage
22 VOR (Slow and Fast)𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Slow vestibulo-ocular reflex (VOR): Since smooth pursuit and VOR systems are both active, if eye movements are choppy with this maneuver this implies deficits in both pursuit and the vestibular system as in CANVAS; Fast (...Image/MovingImage
23 VOR (Suppression)𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Deficits in pursuit and vestibulo-ocular reflex (VOR)S usually go together, except when the VOR is absent or markedly diminished in which case there is no VOR to suppress, so that VORS seems better than pursuit. This is a...Image/MovingImage
24 Horizontal Canal - BPPV: BBQ Roll to Treat the Right Side𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: To treat right horizontal canal (HC)-BPPV (each position maintained for at least 30 seconds or until nystagmus and/or vertigo cease): • First the patient is placed in the long-sitting position • Then in a supine posit...Image/MovingImage
