158 OpsoclonusExample of patients with opsoclonus, a saccadic abnormality. Discussion of characteristics of opsoclonus, such as involuntary, rapid, brief, random, conjugate saccades. Discussion of possible causes, including brain stem encephalitis (as in first patient), a paraneoplastic effect, tumors, and drug t...Image/MovingImage

165 Paradoxical Constriction of Pupils to Darkness (Flynn Phenomenon)Example of patients both with and without paradoxical constriction of pupils. Observed in many congenital retinal disorders, such as achromatopsia, congenital stationary night-blindness, and Leber's congenital amaurosis. Sometimes seen in optic nerve disorders, such as dominant optic atrophy.Image/MovingImage
166 Parinaud's SyndromeTwo examples of patients with Parinaud's syndrome, a dorsal midbrain syndrome. Discussion of hallmarks of this syndrome, including convergence retraction nystagmus, vertical gaze palsies, light-near dissociation, and Collier's Sign. Discussion of age-dependent disorders associated with this syndrome...Image/MovingImage
167 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
168 Periodic Alternating NystagmusExample of a patient with periodic alternating nystagmus, showing an alternation between left-beats and right-beats as the patient maintains forward gaze. Nystagmus maintain horizontal direction regardless of position of gaze.Image/MovingImage
169 Physiologic (End-Gaze) NystagmusDemonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally.Image/MovingImage

171 Progressive Supranuclear PalsyExample of patient with progressive supranuclear palsy. Discussion of difference between saccadic movement in supranuclear palsy and nystagmus. Shows saccadic intrusions in forward gaze, pursuit, saccades, and doll's head maneuver.Image/MovingImage

174 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
175 Pupillogram Demonstrating Paradoxical Pupillary Constriction to DarknessPupillogram demonstrating paradoxical pupillary constriction to darkness in four patients with congenital achromatopsia.
