128 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
129 Flutter in DowngazeExamination of patient with flutter in downgaze (no audio)Image/MovingImage
130 Square Wave JerksExample of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus.Image/MovingImage
131 Intermittent Square Wave JerksPatient with intermittent square wave jerks (no audio)Image/MovingImage
132 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
133 Hemifacial SpasmExample 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

135 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

137 MELAS and RPMELAS; Mitochondrial Encephalopathy with Lactic Acidosis, Stroke and Pigmentary Changes in retina-associated with a retinal dystrophy. This 53 year old man had seizures, encephalopathy and lactic acidosis typical of MELAS. His fundus examination showed granularity and some slight pigmentary changes ...Text
138 Silent Sinus SyndromeSilent sinus syndrome (SSS) is characterized by spontaneous and progressive unilateral enophthalmos.
139 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
140 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
141 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
142 Downbeat NystagmusExample of patient with downbeat nystagmus. Patient is led through instructions of where to gaze. (no audio)Image/MovingImage
143 Downbeat NystagmusExample of patient with downbeat nystagmus. Patient is led through instructions of where to gaze.Image/MovingImage
144 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
145 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
146 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
147 Pathophysiology of Signs Associated with a Tonic PupilPathophysiology of signs associated with a tonic pupil. Normally, all parasympathetic fibers of the third cranial nerve synapse in the ciliary ganglion (top). Most postganglionic fibers innervate the ciliary muscle (dashed lines). After injury to the ciliary ganglion, the pupil becomes denervated an...Image

149 Tadpole-shaped PupilTadpole-shaped pupil in a 20-year-old women with frequent episodes of blurred vision and achiness of the right eye lasting several minutes. The patient took a photograph of her eyes during an attack to document the peaked, segmental dilation of her right pupil (black arow). (Thompson HS, Zackon DH, ...Image
