|
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 |

|
Hemifacial Spasm | Example of patients with hemifacial spasm. First patient has a sequela of Bell's palsy, and is seen to have mainly clonic movements around the eye, with occasional tonic movements around the mouth. Second patient has a cerebellopontine angle epidurmoid tumor, and is seen to have movements around the... | Image/MovingImage |

|
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 |
55 |
|
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... | Image/MovingImage |
56 |
|
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 |
57 |
|
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. | Image/MovingImage |
58 |
|
Downbeat Nystagmus | Example of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. (no audio) | Image/MovingImage |
59 |
|
Downbeat Nystagmus | Example of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. | Image/MovingImage |

|
Convergence Retraction Nystagmus (Parinaud's Syndrome) | Examples of patients with convergence retraction nystagmus. Shows saccadic oscillations in patients looking upwards and following downwards moving targets. Also shows a side-view of the retracting movements of the globes. | Image/MovingImage |
61 |
|
Third Nerve Palsy, Pupil Involving | Example of patient with third nerve palsy. Left eye shows pupilary involvement. Left eye doesn't immediately duct, but abducts well, with impaired superduction. Secondary and primary deviations are demonstrated. Anisocoria is more prominent when light is on, showing a parasympathetic defect to the p... | Image/MovingImage |
62 |
|
Aberrant Regeneration of the Lid | Patient with left third nerve palsy demonstrates anisocoria and mild vertical gaze limitation and aberrant movement of the left upper lid. Patient is instructed through all gaze positions. Left upper lid does not descend during downgaze but retracts instead. | Image/MovingImage |
63 |
|
Light-near Dissociation | Example of patient with Argyll Robertson pupil with neurosyphilis. Shows a lack of pupillary response to light and some pupillary response to nearness of finger. | Image/MovingImage |
64 |
|
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 |
65 |
|
Aberrant Regeneration of the Seventh Nerve | Examples of patients with aberrant regeneration of the seventh nerve. First example is a patient with contractions around the mouth and dimpling, demonstrated with slow and rapid eye blinking. Second example shows contraction around nose with eye blink. | Image/MovingImage |
66 |
|
Aberrant Regeneration of Third Nerve, Bilaterally (1 degree OD, 2 Digrees OS) | Example of patient with bilateral aberrancy of the third nerve. Shows lids popping up (synkinetic) with adduction. Patient had bilateral internal carotid artery aneurisms with third nerve compression. | Image/MovingImage |

68 |
|
Facial Myokymia Unilateral | Example of patient with facial myokymia, a disorder of the seventh nerve, probably due to brain stem involvement. Patient has multiple sclerosis. Discussion of characteristics, such as continuous, undulating, contractions in the distribution of the seventh nerve, and a spreading of these movements t... | Image/MovingImage |
