51 Multifocal ElectroretinogramsThe most important development in ERGs is the multifocal ERG (mfERG). Erich Sutter adapted the mathematical sequences called binary m-sequences creating a program that can extract hundreds of focal ERGs from a single electrical signal. This system allows assessment of ERG activity in small areas of ...
52 Structures of the irisStructures of the iris. The a indicates the anterior border layer that terminates at the pigmentary ruff of the pupillary border (b). The c indicates the iris sphincter muscle, which is oriented circumferentially within the stroma and located deep to the anterior border layer; d indicates vessels th...Image
53 Dysthyroid Optic Neuropathy: A Preventable Cause of BlindnessDysthyroid Optic Neuropathy (DON) is a treatable cause of visual loss in ~5% of pts w/ ted. Monitor closely those pts with risk factors (proptosis, tight orbit, restricted motility, strabismus, smoker, diabetic). Oral prednisone is often effective, but frequent relapses after tapering. Orbital xrt ...

57 The Wall-Eyed Potato FarmerYoung man presenting with apparent episodic neurologic evants that initially was thought to be multiple sclerosis, but as time went on, he had progressive changes in his neurologic exam and in his imaging findings. Brain biopsy revealed Gliomatosis cerebri. Anatomy: Brain Stem; Pons; Midbrain. Patho...
58 Pupillogram Demonstrating Paradoxical Pupillary Constriction to DarknessPupillogram demonstrating paradoxical pupillary constriction to darkness in four patients with congenital achromatopsia. Note that the pupils initially constrict when the light is extinguished. (Price MJ, Thompson HS, Judisch GF et al: Pupillary constriction to darkness. Br J Ophthalmol 1981;69:205-...Image
59 Left-sided Internal Carotid Artery DissectionLeft-sided internal carotid artery dissection identified on T-1 weighted magnetic resonance image from a 52-year-old man who suddenly developed left-sided neck and orbital pain along with a droopy left upper eyelid while dragging a deer out of the woods during hunting season. The normal dark flow vo...Image
60 Right-sided Pseudo-Horner's SyndromeRight-sided pseudo-Horner's syndrome in an 8-month-old infant referred because her mother had noted a larger pupil on the left for a few months and her pediatrician thought the right upper lid was droopy. Both pupils reacted normally to light and darkness, the degree of anisocoria was similar in bot...Image
61 Gaze Palsy with Facial Weakness from Pontine AVMExample of a patient with torsional nystagmus in both eyes and pendular nystagmus in the left eye. Patient is led through instructions for direction of gaze.Image/MovingImage
62 An Enhancing Bladder Metastasis Involving the Tectum of the MidbrainMagnetic resonance image of an enhancing bladder metastasis involving the tectum of the midbrain of a 56-year-old man who developed double vision resulting from skew deviation and divergence insufficiency. He also had a left-sided relative afferent pupillary defect measuring 1.4 log units but showed...Image
63 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
64 Wall-Eyed Bilateral Internuclear Ophthalmoplegia (WEBINO)Example of patient with horizontal binocular diplopia. Demonstration of exam, which shows alternating exotropia in cover test. As patient follows object, right eye does not pass the midline as the object moves to the left, while left eye go slightly past the midline, but does not abduct completely. ...Image/MovingImage

66 Light-near DissociationLight-near dissociation in a 51-year-old woman with multiple sclerosis who experienced double vision for 1 week. Her pupils are 5 mm in diameter in room light (top), react poorly in response to direct light reaction (middle), but constrict promptly in response to near stimulation (bottom). She also ...Image
67 Migraine and Cluster Pathophysiology and TreatmentVideo lecture covering pathophysiology and treatment of migraine and cluster headaches by Kathleen Digre, MD.
68 The Normal Pupillary Light ReflexThe normal pupillary light reflex is initiated following exposure to light. After a brief latency, both the right (solid line) and left (broken line) pupil constrict, then undergo a small amount of redilation (escape), followed by oscillations (hippus) if the light is sustained. Hippus is not a path...Image

70 Duane's Retraction Syndrome Type 3Example of a patient with Type 3 Duane's Retraction Syndrome, as well as bilateral Duane's Syndrome. Shows limitation of abduction in both eyes and adduction in the left eye. Also shows side-view of globe retraction in abduction.Image/MovingImage
