Argyll Robertson Pupils | Argyll 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 |

Sector Palsies and Light-Near Dissociation | Example of patient with bilateral Adie's pupils. Exam is performed with a slit-lamp. Shows iris stroma and focal segments of iris sphincter that retain their contractilty. Suggests post-ganglionic parasympathetic denervation. | Image/MovingImage |

Left-sided Dilation Lag in a Man with Horner's Syndrome | Left-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 |

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). Th... | Image |

Pupil Signs in a 32-year-old Woman with Right-sided Adie's Pupil | Pupil 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 |

Transillumination - Lisch Nodules | Demonstration of transillumination of the Lisch nodules on a patient with neurofibromatosis. Shows how Lisch nodules that were not very visible in slit-lamp examination are better seen with transillumination, which may therefore be useful in detecting Lisch nodules earlier in children where they are... | Image/MovingImage |
