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. | Image/MovingImage |

Ocular Lateropulsion (Wallenberg's Syndrome) | Example of patient with ocular lateropulsion. Patient also has central Horner syndrome and nystagmus in right gaze. When shifting gaze back to forward, eyes overshoot their mark. Eyes laterally deviate to the right upon opening. | Image/MovingImage |

|
Ocular Myasthenia | Example of patient with myasthenia gravis. Demonstration of tensilon test. Patient shown to have bilateral ptosis, bilateral duction deficits, and left hypertropia. Discussion of techniques to observe subtle changes, such as bringing in a neutral observer or taking still photographs. Shows split-scr... | Image/MovingImage |

|
Ocular Myotonia | Example of patient with ocular myotonia. Patient is led through instructions for direction of gaze and opening and closing of eyes. Right eye is shown to be stuck in position after held gaze to the left and right, with very slow relaxation back into forward gaze. | Image/MovingImage |

Oculopalatal Myoclonus | Oculopalatal myoclonus (OPM) Rhythmic oscillations of eyes and palate. Occurred after specific brainstem injury from stroke, following stenting.

Opsoclonus | Example of patients with opsoclonus, a saccadic abnormality. Discussion of characteristics of opsoclonus, such as involuntary, rapid, brief, random, conjugate saccades. Discussion of possible causes, including brain stem encephalitis (as in first patient), a paraneoplastic effect, tumors, and drug t... | Image/MovingImage |

|
Paradoxical Constriction of Pupils to Darkness (Flynn Phenomenon) | Example of patients both with and without paradoxical constriction of pupils. Observed in many congenital retinal disorders, such as achromatopsia, congenital stationary night-blindness, and Leber's congenital amaurosis. Sometimes seen in optic nerve disorders, such as dominant optic atrophy. | Image/MovingImage |

|
Parinaud's Syndrome | Two examples of patients with Parinaud's syndrome, a dorsal midbrain syndrome. Discussion of hallmarks of this syndrome, including convergence retraction nystagmus, vertical gaze palsies, light-near dissociation, and Collier's Sign. Discussion of age-dependent disorders associated with this syndrome... | Image/MovingImage |

|
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 |
88 |
|
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. | Image/MovingImage |

|
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 |
91 |
|
Pulsating Exophthalmos | Example of a patient with neurofibromatosis with an absent sphenoid wing. Shows left eye pulsating back and forth with the pulse from front and side views. | Image/MovingImage |

RAPD Present | This clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient. | Image/MovingImage |
94 |
|
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 |
