Title | Description | Type |
1 |
|
Binocular Pendular Nystagmus | Example of a patient with binocular pendular nystagmus. Patient has somewhat dissociated nystagmus, with nystagmus seen more prominently in the left eye. Patient shows an occasional jerk nystagmus to the right in the right eye. Left eye oscillations are mostly pendular. | Image/MovingImage |

Superior Oblique Myokymia | Close-up video of a patient with superior oblique myokymia (no audio.) | Image/MovingImage |
3 |
|
Rebound Nystagmus | Example of a patient with rebound nystagmus, where the oscillations alternate direction as the patient shifts gaze in different directions. Discussion of relationship to disease and disorders of the cerebellum, including degenerations of the cerebellum, infarction, and demyelination. | Image/MovingImage |
4 |
|
Brun's Nystagmus | Observation of patient with Brun's Nystagmus. Shows patient gazing to the right and the nystagmus beating in the direction of the gaze. | Image/MovingImage |
5 |
|
Periodic Alternating Nystagmus | Example of a patient with periodic alternating nystagmus, showing an alternation between left-beats and right-beats as the patient maintains forward gaze. Nystagmus maintain horizontal direction regardless of position of gaze. | Image/MovingImage |
6 |
|
Retraction Nystagmus | Patient with retraction nystagmus (no audio) | Image/MovingImage |
7 |
|
Monocular Pendular Nystagmus | Example of a patient with monocular pendular nystagmus, with discussion of situations in which this condition is seen: acquired disorder of the visual-sensory pathway, and acquired disorder of the brain stem (e.g. multiple sclerosis). | Image/MovingImage |
8 |
|
See-saw Nystagmus | Example of a patient with see-saw nystagmus, showing how one eye elevates as the other depresses, with the elevating eye intorting as the depressing eye extorts. Shows vertical oscillations with pendular waveforms. Suggests a large structural lesion in the pericellar region (associated with bi-tempo... | Image/MovingImage |
9 |
|
Congenital Nystagmus | Example of patients with congenital nystagmus. First patient's nystagmus are mostly jerk and not pendular. Second patient's nystagmus are mostly pendular. Both patients show a uniform horizontal oscillation. Second patient also shows differences in frequency of oscillations depending on gaze, includ... | Image/MovingImage |

|
Congenital Nystagmus | Patient with congenital nystagmus (no audio) | Image/MovingImage |
11 |
|
Spasmus Nutans | Example of patient with spasmus nutans. Discussion of characteristics of this disorder, such as dissociated or monocular nystagmus, abnormal head position, and to-and-fro head oscillation. Sometimes an eccentric gaze is seen as well (as in patient). Patient has a monocular horizontal nystagmus in th... | Image/MovingImage |

|
Before Tensilon | Example of patient with myasthenia gravis. Demonstration of baseline examination, followed by administration of 2mg of tensilon, which is a test dose. Procedure for administration of tensilon test is described, including variations. Patient is then shown after being given 4mg of tensilon, with very ... | Image/MovingImage |
13 |
|
Progressive Supranuclear Palsy | Example of patient with progressive supranuclear palsy. Discussion of difference between saccadic movement in supranuclear palsy and nystagmus. Shows saccadic intrusions in forward gaze, pursuit, saccades, and doll's head maneuver. | Image/MovingImage |
14 |
|
Blepharospasm | Example of patient with blepharospasm. Patient is led through instructions for direction of gaze and opening and closing of eyes. Patient is led through same exercises again after receiving indomethacin treatment. | Image/MovingImage |

|
2-37a - Vascular Features | When looking at the disc, the central retinal artery and vein should be visible. The central retinal artery is usually slightly narrower than the vein. When the central retinal artery goes though the lamina cribrosa, the artery becomes smaller because of diminution of the muscular layer and loss of ... | Image |

Bilateral Ptosis | Video of patient with bilateral ptosis. | Image/MovingImage |
17 |
|
2-37b - Vascular Features | When looking at the disc, the central retinal artery and vein should be visible. The central retinal artery is usually slightly narrower than the vein. When the central retinal artery goes though the lamina cribrosa, the artery becomes smaller because of diminution of the muscular layer and loss of ... | Image |

|
Rotary Downbeat | Patient with rotary downbeat nystagmus (no audio) | Image/MovingImage |
