51 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
52 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
53 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
54 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
55 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
56 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
57 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
58 Left-sided Dilation Lag in a Man with Horner's SyndromeLeft-sided dilation lag in a 29-year-old man with Horner's syndrome caused by a posterior mediastinal ganglioneuroma. Note that the degree of anisocoria is greater after 5 seconds in darkness (top) compared with findings after 15 seconds in darkness (bottom).Image
59 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
60 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
61 Pupil Signs in a 32-year-old Woman with Right-sided Adie's PupilPupil signs in a 32-year-old woman with right-sided Adie's pupil. The right pupil is larger than the left pupil (top), reacts poorly to direct light stimulation (second panel), and better in response to near stimulation (third panel). The right pupil also shows a supersensitive response 30 minutes a...Image
62 Tadpole-shaped PupilTadpole-shaped pupil in a 20-year-old women with frequent episodes of blurred vision and achiness of the right eye lasting several minutes. The patient took a photograph of her eyes during an attack to document the peaked, segmental dilation of her right pupil (black arow). (Thompson HS, Zackon DH, ...Image
63 Argyll Robertson PupilsArgyll Robertson pupils in an elderly man treated for tabes dorsalis in 1952. His pupils are small and slightly irregular, constrict poorly in response to light stimulation (top), dilate poorly in darkness (middle), but constrict promptly in response to near stimulation (bottom).Image
64 Aberrant Regeneration of the Right PupilAberrant regeneration of the right pupil in a man with a large intracavernous sinus meningioma causing a pupil-involving, incomplete third cranial nerve palsy. His pupil is round when he gazes straight ahead (top). When he tries to rotate the eye medially, the pupil constricts, but a segment of the ...Image
