TitleDescriptionType
26 OpsoclonusExample 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
27 Pulsating ExophthalmosExample 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
28 Superior Oblique MyokymiaExample 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
29 Ocular MyotoniaExample 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
30 Downbeat NystagmusExample 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
31 Downbeat NystagmusExample of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. (no audio)Image/MovingImage
32 Downbeat NystagmusExample of patient with downbeat nystagmus. Patient is led through instructions of where to gaze.Image/MovingImage
33 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
34 Third Nerve Palsy, Pupil InvolvingExample 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
35 Aberrant Regeneration of the LidPatient 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
36 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
37 Aberrant Regeneration of the Seventh NerveExamples 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
38 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
39 Facial Myokymia UnilateralExample 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
40 Bilateral Facial MyokymiaExample of a patient with a brain stem glioma. Shows bilateral facial myokymia.Image/MovingImage
41 Unilateral BlepharospasmExample of patient with unilateral blepharospasm.Image/MovingImage
42 Blepharospasm with Apraxia of the EyeImage/MovingImage
43 Voluntary NystagmusExample of patient with voluntary nystagmus. Discussion of how a lack of uniform, patterned movement of the eyes along with associated lid movements suggests that activity is voluntary.Image/MovingImage
44 Levator DisinsertionExample of patient with levator disinsertion, a lid disorder. Patient is pregnant and wears poorly fitting contacts. Discussion of characteristics, such as lid ptosis (shown in the left eye of patient), but with full levator function.Image/MovingImage
45 Marcus Gunn Jaw WinkingExample of patient with Marcus Jaw Winking. Patient is led through instructions for movement of jaw (open, close, back and forth), with eyelid seen to be affected. Patient is then led through instructions for direction of gaze and pursuit.Image/MovingImage
46 CPEOPatient with Chronic Progressive External Ophthalmoplegia (CPEO)Image/MovingImage
47 Duane's Retraction Syndrome Type 1: Lid RetractionExample of patients with Duane's Retraction Syndrome, Type 1. Description of components of Duane's Syndrome: limitation of abduction, variable limitation of adduction, and palpebral fissure narrowing and globe retraction with attempted adduction. Type 1 includes limited or absent abduction with norm...Image/MovingImage
48 Cogan's Lid TwitchExample of a patient with Cogan's lid twitch, with discussion of how to detect it in an exam.Image/MovingImage
49 Fourth Nerve PalsyDemonstration of examination of patient who experienced blurry vision and pain in the left eye. Demonstrates checking of eye movements, focusing on object while each eye is covered and uncovered, turning head both ways and repeating. Shows limitation of depression in adduction of left eye, left hype...Image/MovingImage
50 3 Step TestDemonstration of patient examination.Image/MovingImage
