153 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

156 Central Retinal Artery OcclusionVideo of central retinal artery occlusion.Image/MovingImage
157 Glaucoma: The BasicsGlaucoma is the most common optic neuropathy. Progressive cupping of the optic disc due to increased intraocular pressure together with visual field abnormalities and local disc susceptibility factors characterize this neuropathy. This PowerPoint lecture covers the basics of Glaucoma and includes ma...Text

159 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
160 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

162 3-31b - Papilledema StagesGrading Papilledema: Stage 0 GRADING PAPILLEDEMA GRADING PAPILLEDEMA We grade papilledema in order to tell us how severe it is. The most sensible grading scheme has been provided by Lars Frisén. STAGE 0: This woman had documented increased intracranial pressure of 340 mm water. Very little if any ...Image
163 3-35a - Papilledema StagesGrading Papilledema: Stage 4 Stage 4 = Complete obliteration of the cup and complete obscuration of at least some vessels on the surface of the disc. There may be small dilated capillaries on the disc that resemble telangiectasia. It is not the NFL infarcts or hemorrhages but the obscuration of the ...Image
164 3-66a - Shunt Vessels (Post-papilledema)The retino-choroidal collaterals seen with chronic papilledema begin with a "Hairnet" of telangiectasias that gradually winnow down to one or more large collateral tortuous draining channel. The presence of these vessels is evidence of long standing disc swelling. When the CSF pressure is lowered, t...Image
165 3-66d - Shunt Vessels (Post-papilledema)The retino-choroidal collaterals seen with chronic papilledema begin with a "Hairnet" of telangiectasias that gradually winnow down to one or more large collateral tortuous draining channel. The presence of these vessels is evidence of long standing disc swelling. When the CSF pressure is lowered, t...Image
166 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
167 How to Use the Direct Ophthalmoscope in an ExamDemonstration of using the direct ophthalmoscope to examine the optic disc. Covers hand placement , which eye to use, and distance from patient.Image/MovingImage
168 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 ...
169 Notching of the Neuro-retinal RimThe neuro-retinal rim becomes thinner; in particular the rim superotemporally and inferortemporally may develop a notch which is usually superior or inferior and rarely nasal or temporal. These notches are believed to be due to focal ischemic damage to the neuro-retinal rim. Glaucoma with Notching a...Image
170 RAPD PresentThis clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient.Image/MovingImage
171 Retino-choroidal Vessels or Optociliary Veins or Ciliary ShuntOverview of retino-choroidal collaterals, which are potential telangiectatic connections between the retina and choroidal circulation. Although sometimes called "shunts", these collaterals are between the retinal venous circulation and the choroidal venous circulation.Text
172 Testing the Visual FieldsDemonstration of various methods of testing visual fields, including counting fingers, motion, and color of several objects.Image/MovingImage
173 Tour of the Direct OphthalmoscopeThis clip describes the parts and operation of the ophthalmoscope as an ocular examination tool. Includes adjustment of aperture size and adjustment of lenses.Image/MovingImage
174 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
