 |
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 |

 |
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 |
| 34 |
 |
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 |
| 35 |
|
2-13 | Rotary Nystagmus | Example of a patient with rotary nystagmus, showing occasional counterclockwise rotary movements of both eyes. Seen more in intrinsic disorders of the brainstem. | Rotary (Torsional) Nystagmus |
| 36 |
 |
2-14 | Dissociated Nystagmus | Example of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye. | Dissociated Nystagmus |
| 37 |
 |
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 |
| 38 |
 |
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 |
| 39 |
|
2-17 | Ocular Flutter | Two examples of patients, the first with rotary, flutter-like movements, but not ocular flutter, and the second with genuine ocular flutter. Discussion of difference between ocular flutter and nystagmus, and how to elicit ocular flutter. | Ocular Flutter |
| 40 |
 |
2-19 | Superior Oblique Myokymia | Example of patients with superior oblique myokymia, a saccadic intrusion. First patient is seen to have intermittent, intorting movements with superimposed slight vertical deviations in right eye. Discussion of disorder as benign, but frequently disabling, as patients experience episodes of diplopia... | Superior Oblique Myokymia; Third Nerve Palsy |
| 41 |
|
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 |
| 42 |
 |
2-20 | Square Wave Jerks | Example of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus. | Square Wave Jerks |
