201 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
202 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
203 Optic Disc Pallor Pseudo and RealDiscussion of the causes of optic disc pallor.Text
204 Testing the Visual FieldsDemonstration of various methods of testing visual fields, including counting fingers, motion, and color of several objects.Image/MovingImage
205 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
206 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
207 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
208 Bilateral Facial MyokymiaExample of a patient with a brain stem glioma. Shows bilateral facial myokymia.Image/MovingImage
209 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
210 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
211 Normal Light Reflex without RAPDThis clip demonstrates the examination of the Relative Afferent Pupillary Defect (RAPD.) Demonstration of gauging the size of the pupil in light, testing light reflexes, swinging flashlight test for optic nerve abnormality.Image/MovingImage
212 Enhanced Mydriasis in Response to HydroxyamphetamineEnhanced mydriasis in response to hydroxyamphetamine in a 77-year-old woman with a long-standing, preganglionic, right-sided Horner's syndrome that occurred following cervical neck dissection for thoracic outlet syndrome 30 years earlier. Miosis of the right pupil is apparent in room light (top). Th...Image
213 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
214 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
215 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
216 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
217 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
218 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
219 How to Measure the RAPDThis clip demonstrates the examination technique for measuring the Relative Afferent Pupillary Defect (RAPD). Demonstration of balancing an afferent papillary defect using filters in a patient with a resolving optic neuritis and an afferent papillary defect on the left.Image/MovingImage
220 Right-sided Relative Afferent Pupillary DefectRight-sided relative afferent pupillary defect in a man with optic nerve glioma. When the unaffected left eye is stimulated by light, both pupils constrict (top). When the light is then swung over to the affected right eye, both pupils dilate (bottom). This indicates that pupillomotor conduction thr...Image
221 RAPD PresentThis clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient.Image/MovingImage
222 Bilateral Iris ColobomasColoboma literally means a "gap"-and can be used to describe any fissure, hole, or gap in the eye. The term most often is used to refer to a congenital gap in the disc, retina, the choroid, and the iris. Colobomas occur because the embryonic fissure fails to fuse. Since the fissure closure begins in...Image
223 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
224 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
225 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
