2-15 | Vestibular Nystagmus | Discussion of vestibular nystagmus. Seen with peripheral disorders and central disorders, and in two varieties: spontaneous and positional. Horizontal jerk with small amplitude. | Vestibular Nystagmus; Jerk Nystagmus; Peripheral Vestibular Nystagmus; Positional Nystagmus |
| 2 |
 |
2-9 | 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). | Monocular Pendular Nystagmus; Sensory Nystagmus; Pendular Nystagmus; Acquired Pendular Nystagmus |
| 3 |
 |
2-7 | Abducting (Dissociated) Nystagmus | Example of a patient with abducting (dissociated) nystagmus. Patient has a subtle internuclear ophthalmoplegia. Right eye has right-beating jerk nystagmus, with smaller oscillations in the left eye. Disease/Diagnosis: Abducting Nystagmus | Abducting Nystagmus; Dissociated Nystagmus |
| 4 |
 |
2-10 | 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. | Binocular Pendular Nystagmus; Pendular Nystagmus; Acquired Pendular Nystagmus |
| 5 |
 |
2-16 | Physiologic (End-Gaze) Nystagmus | Demonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally. | End-Gaze Nystagmus; Physiologic Nystagmus |
| 6 |
 |
2-8 | 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. | Rebound Nystagmus; Gaze-Evoked Nystagmus |
| 7 |
|
2-2 | Latent Nystagmus | Example of a patient with latent nystagmus. Demonstrates a lack of oscillations in forward gaze, followed by the occlusion of each eye, showing how this generates a jerking oscillation in the non-occluded eye away from the occluded eye. | Latent Nystagmus; Fusional Maldevelopment Nystagmus Syndrome |
| 8 |
 |
2-1 | 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... | Congenital Nystagmus |

 |
NOVEL_Moran_3a-30 | Congenital Nystagmus | Patient with congenital nystagmus (no audio) | Congenital Nystagmus |
| 10 |
 |
2-14 | Dissociated Nystagmus | Example of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye. | Dissociated Nystagmus |
| 11 |
 |
2-6 | Downbeat Nystagmus | Example of patients with downbeating jerk nystagmus. Demonstrates how oscillations grow more prominent when the patient gazes down or laterally. Discusses some causes, including Arnold-Chiari malformation, infarction, and demyelination. | Downbeat Nystagmus |
| 12 |
 |
NOVEL_Moran_3a-1 | Downbeat Nystagmus | Example of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. (no audio) | Downbeat Nystagmus |
| 13 |
 |
NOVEL_Moran_3a-9 | Downbeat Nystagmus | Example of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. | Downbeat Nystagmus |
| 14 |
 |
NOVEL_Moran_3a-17 | Retraction Nystagmus | Patient with retraction nystagmus (no audio) | Retraction Nystagmus |
| 15 |
 |
NOVEL_Moran_3a-22 | Vestibular Nystagmus | Example of patient with vestibular nystagmus. Patient is led through instructions for direction of gaze. Shown also with Frenzel goggles. | Vestibular Nystagmus |
| 16 |
 |
2-11 | 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. | Brun's Nystagmus; Cyclical |
| 17 |
 |
2-12 | 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. | Periodic Alternating Nystagmus |
| 18 |
 |
NOVEL_Moran_3a-36 | Rotary Downbeat | Patient with rotary downbeat nystagmus (no audio) | Rotary Downbeat Nystagmus |

| 20 |
 |
2-4 | 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.

Katz_seesaw | See-saw Nystagmus | 7-year-old female whose mother noticed her eyes "bouncing" for 2 months. Visual acuity 20/70 OD and 20/40 OS, reduced color vision OU, and no afferent pupillary defect. See-saw nystagmus documented with videography.
