76 Anterior Ischemic Optic NeuropathyPPT describing Anterior Ischemic Optic Neuropathy (AION). Covers clinical signs, such as monocular vision loss, swollen nerve, and visual field defects, as well as risk factors.Text
77 4-54b - Optic Neuropathy, Ischemic: PosteriorImage
78 3-3 - Bergmeister PapillaImage
79 3-4 - Tilted DiscTilted discs are normal variants caused by oblique insertion of the optic nerve to the globe. They can be and frequently are mistaken for papilledema. In this case the superior edge of the disc is tilted and appears elevated. This disc exhibits a nasal inferior tilt.Image
80 3-5b - Myelinated Nerve FibersMyelinated nerve fibers are frequently confused with papilledema. The feathery edge of the myelinated fibers that conceal the disc and vessel should provide the clue. These myelinated nerve fibers make the disc look blurred.Image
81 3-33b - Papilledema StagesGrading Papilledema: Stage 2 = Elevation of the disc margin 360 degrees. Since the blood vessels at the disc margin are not swollen or obscured, this disc could be mistaken for pseudo-papilledema.Image
82 Papilledema 2013Discussion of papilledema, the swelling due to increased pressure.Text
83 2-37a - Vascular FeaturesWhen looking at the disc, the central retinal artery and vein should be visible. The central retinal artery is usually slightly narrower than the vein. When the central retinal artery goes though the lamina cribrosa, the artery becomes smaller because of diminution of the muscular layer and loss of ...Image
84 Location of Pupillomotor FibersLocation of pupillomotor fibers are depicted as dark regions on cross-sections of the right (R) and left (L) oculomotor nerve at various locations along its course, including its emergence from the brain stem in the interpeduncular fossa (1), the midsubarachnoid segment (2), the level of the dorsum ...Image
85 Anatomy of the Pupillary Light Reflex PathwayAnatomy of the pupillary light reflex pathway. (Miller NR: Walsh And Hoyt's Clinical Neuro-Ophthalmology, p 421. Vol 2, 4th ed. Baltimore: Williams & Wilkins, 1985, with permission.)Image
86 The Course of the Postganglionic Segment of the Oculosympathetic Fibers from the Internal Carotid ArteryThe course of the postganglionic segment of the oculosympathetic fibers from the internal carotid artery (ICA) to the orbit is depicted as a dotted line. Note that they briefly join the abducens nerve (cranial nerve VI) before joining the nasociliary branch of the of the ophthalmic division of the t...Image
87 Anatomy of the Oculosympathetic PathwayAnatomy of the oculosympathetic pathway. (Maloney WF, Younge BR, Moyer NJ: Evaluation of the causes and accuracy of pharmacologic localization in Horner's syndrome. Am J Ophthalmol 1980;90:394-402, Ophthalmic Publishing Company with permission.)Image
88 Bilateral PtosisVideo of patient with bilateral ptosis.Image/MovingImage
89 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
90 2-37b - Vascular FeaturesWhen looking at the disc, the central retinal artery and vein should be visible. The central retinal artery is usually slightly narrower than the vein. When the central retinal artery goes though the lamina cribrosa, the artery becomes smaller because of diminution of the muscular layer and loss of ...Image
91 Central Retinal Artery OcclusionVideo of central retinal artery occlusion.Image/MovingImage
92 Optic Disc Pallor Pseudo and RealDiscussion of the causes of optic disc pallor.Text
93 Pupillogram of a Healthy Young SubjectPupillogram of a healthy young subject showing continuous pupillary oscillations of both pupils when light is sustained, indicated by the dark arrow at the top of the recording. Note that the oscillations of the pupils are synchronous and demonstrate variable amplitude and frequency. This pattern of...Image
94 Relationship Between Age and Pupil SizeRelationship between age and pupil size, determined using an infrared flash photograph technique with subjects placed in darkness for 3 minutes. The numbers above the abscissa indicate the number of subjects tested in each age range. (Reprinted with permission of Loewenfeld IE: "Simple, central" ani...Image
95 Left-sided Horner's Syndrome with an Acquired Preganglionic LocalizationLeft-sided Horner's syndrome in a 12-year-old girl with an acquired preganglionic localization based on clinical and pharmacologic testing. The cause remained undetermined after extensive radiologic investigations. Left-sided ptosis and miosis are evident in room light (top), and the degree of aniso...Image
96 Bilateral Iris Colobomas (B)Bilateral iris colobomas. B. Bilateral colobomatous defects of the inferonasal retina (black arrows) are also present, as shown in the right eye.Image
97 Flow Chart for Sorting Out Anisocoria - Bright Light and DarknessFlow chart for sorting out anisocoria based initially on how it is influenced by bright light and darkness.Image
98 Flow Chart for Sorting Out Anisocoria - Direct Light Reaction of the PupilFlow chart for sorting out anisocoria based initially on the integrity of the direct light reaction of the pupil.Image
99 Assessment of an Afferent Pupillary Defect When Only One Iris is FunctionalAssessment of an afferent pupillary defect when only one iris is functional. In this example, a right-sided parasellar tumor is compressing both the optic and oculomotor nerves, causing an optic neuropathy and a pupil-involving third crainial nerve palsy. The pupil on the affected side has both an a...Image
100 Hand-held Equipment Used to Measure a Relative Afferent Pupillary DefectHand-held equipment used to measure a relative afferent pupillary defect and to record pupil sizes. Four neutral density filters (0.3, 0.6, 0.9, 1.2 log units) are conveniently carried in a soft cloth carrying pouch. A bright light source (a Finhoff model illuminator is shown here) is ideal for stim...Image
