1 | Figure-23 | Enhanced Mydriasis in Response to Hydroxyamphetamine | Enhanced 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).

2 | 1-1 | How to Measure the RAPD | This 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. | Relative Afferent Pupillary Defect (RAPD); Examination, Pupillary | |
3 | RAPD_Not_Present | Normal Light Reflex without RAPD | This 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. | Relative Afferent Pupillary Defect (RAPD); Examination, Pupillary; Swinging Flashlight Test | |
4 | RAPD_present | RAPD Present | This clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient. | Relative Afferent Pupillary Defect (RAPD); Examination, Pupillary; Afferent Pupillary Defect | |
5 | Figure-06 | The Normal Pupillary Light Reflex | The 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... | Reflex, Pupillary; Examination, Pupillary |
