Traumatic Internal Carotid Atery Dissection | Steven Galetta, MD | Traumatic dissection of the carotid artery may result in neck pain, an ipsilateral Horner's syndrome (disruption of the pericarotid sympathetic fibers), or ipsilateral arterial occlusions from embolic disease. Pair with images 91_19 and 91_20. |

Magnetic Resonance Imaging in Detection of Extracranial Internal Carotid Artery Dissection | Marilyn C. Kay, MD | This 28-year-old woman presented with a 4-week history of bilateral visual loss. She had a known history of multiple sclerosis. Her vision was 20/60 OD and 20/40 OS, with an RAPD OS and optic pallor OU. Her fields and MRI are shown. Optic tract lesions usually result in an incongruous homonymous hem... |

Neuro-Ophthalmic Consequences of Therapy | Mark J. Kupersmith, MD | radiation retinopathy may mimic diabetic or hypertensive optic neuropathy. A history of irradiation to the eye, orbit, or head is mandatory. Radiation retinopathy usually occurs many months after radiation therapy. |

 |
Neuro-Ophthalmic Consequences of Therapy | Mark J. Kupersmith, MD | Radiation causes a vascular retinopathy that may mimic diabetic or hypertensive retinopathy. It does not develop until many months or several years after radiation therapy to the eye, orbit or head. |

 |
Neuro-Ophthalmic Vascular Disease | Mark J. Kupersmith, MD | Aneurysms of the intracranial circulation may act as mass lesions and compress the afferent of efferent visual pathway. Ophthalmic artery aneurysms may compress the optic nerve and result in an optic neuropathy (ie, visual loss, afferent pupillary defect, optic atrophy). Treatment includes endovascu... |

 |
Isolated Optic Neuritis/Neuropathy | Mark J. Kupersmith, MD | Papilledema may produce visual loss due to chronic atrophic papilledema, secondary macular hemorrhage, exudate or edema, secondary ischemic optic neuropathy, or secondary subretinal neovascular membrane formation. Patients with papilledema and visual loss should be suspected of harboring one of thes... |

Neuro-Ophthalmic Vascular Disease | Mitchell J. Wolin, MD | Carotid cavernous fistulas (CCFs) are connections between the arterial blood flow from the carotid artery system and the cavernous sinus. CCFs may be direct high-flow fistulas or indirect low-flow fistulas. Most direct CCFs are due to trauma. Enlargement of the superior ophthalmic vein may be demons... |

Systemic Disorders With Optic Nerve and Retinal Findings | Mark J. Kupersmith, MD | Sarcoidosis is an inflammatory multisystem granulomatous disease that may result in an inflammatory or infiltrative optic neuropathy, papilledema from increased intracranial pressure due to meningeal inflammation or intracranial granuloma, or may present with an optic disc granuloma. Pair with 91_31... |

Motility Disturbances | Mitchell J. Wolin, MD | The trochlear nerve (fourth nerve) runs from the midbrain, exits dorsally, crosses in the anterior medullary velum, enters the subarachnoid space, travels within the lateral wall of the cavernous sinus, and enters the orbit through the superior orbital fissure. A trochlear nerve palsy may be due to ... |

Ocular Manifestations of Congenital/Inherited Diseases | Larry P. Frohman, MD | This girl was 8 years old when these photographs were taken. She had been referred by pediatric neurology with ataxia. When seen, the findings of ataxia, poor convergence, early head thrusting maneuvers, and relatively preserved motility, in conjunction with the conjunctival findings as seen in the ... |

Chiasmal Syndromes | Larry P. Frohman, MD | This 39-year-old HIV-positive man presented in 1982 with 1 month of bilateral vision loss. His prior evaluation had included 2 CT scans, which suggested a fullness to the chiasm, and a spinal tap that showed 6 monocytes, 14 red cells, a protein of 81 mg/dl, and a glucose of 56 mg/dl, with a negative... |

Ocular Manifestations of Congenital/Inherited Diseases | Larry P. Frohman, MD | On optic nerve CT scan, this patient with neurofibromatosis, type 1, shows the classic railroad-track sign of optic nerve meningioma and the kink sign of optic nerve glioma.

Motility Disturbances | Larry P. Frohman, MD | A 27-year-old healthy man presented for neuro-ophthalmologic evaluation for recurrent vertical binocular diplopia. In 1982, he had a minor blow to the head, and 12 days later he sustained vertical binocular diplopia, worse on downgaze, without ever having diurnal variation. His sense of taste was al... |
