101 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
102 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
103 Binocular Pendular NystagmusExample 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.Image/MovingImage
104 Cogan's Lid TwitchExample of a patient with Cogan's lid twitch, with discussion of how to detect it in an exam.Image/MovingImage
105 Spontaneous Venous PulsationsThis clips shows a spontaneous venous pulsation viewed during an ocular examination.Image/MovingImage
106 Ocular FlutterTwo 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
107 Dissociated NystagmusExample of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye.Image/MovingImage
108 Congenital NystagmusExample 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...Image/MovingImage
109 Upbeat NystagmusExample of a patient with upbeat nystagmus. Shows vertical jerk nystagmus with fast phases in the up direction. Localizes to brain stem, and occurs with strokes, demyelination, and tumors.Image/MovingImage
110 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
111 Duane's Syndrome Type 2: Aberrant Regeneration of the Third and Sixth NervesExample of a patient with Type 2 Duane's Syndrome. Demonstrates limitation of adduction in left eye with normal abduction. Discussion of limited pathological cases.Image/MovingImage
112 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
113 Abducting (Dissociated) NystagmusExample 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.Image/MovingImage
114 Light-Near DissociationExample 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
115 See-Saw NystagmusExample 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. Shows vertical oscillations with pendular waveforms. Suggests a large structural lesion in the pericellar region (associated with bi-tempo...Image/MovingImage
116 Physiologic (End-Gaze) NystagmusDemonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally.Image/MovingImage
117 Square Wave JerksExample of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus.Image/MovingImage
118 Aberrant Regeneration of the Third and Sixth NervesImage/MovingImage
119 Spasm of the Near ReflexExample of patient with spasm of the near reflex and voluntary nystagmus. Discussion of similar-looking conditions (e.g. six nerve palsy, limitation of abduction, lateral rectus muscle problems) and how to tell them apart from spasm of the near reflex by observing the myosis evoked by the near respo...Image/MovingImage
120 Brun's NystagmusObservation of patient with Brun's Nystagmus. Shows patient gazing to the right and the nystagmus beating in the direction of the gaze.Image/MovingImage
121 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
122 Latent NystagmusExample 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.Image/MovingImage
123 Monocular Pendular NystagmusExample 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).Image/MovingImage
124 Ocular MyastheniaExample 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
125 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
