Optic Tract Syndrome Due to Carotid Artery Dolichoectasia | Larry P. Frohman, MD | This 43-year-old man was referred for evaluation of 6 months of visual loss OU. In retrospect, he had noticed increasing difficulty with his tennis game dating back over 3 years, as balls would pass him unexpectedly when hit to his backhand (left) side. The patient did not think this was progressive... |

Isolated Congenital Optic Disc Anomalies | Rosa A. Tang, MD | This patient has optic disc drusen and evidence of a superimposed optic neuropathy, including loss of visual field, an ipsilateral afferent pupillary defect, and optic atrophy. Although optic disc drusen typically causes visual field loss without visual acuity loss superimposed, ischemic optic neuro... |

 |
Orbital Tumors | Mitchell J. Wolin, MD | Cavernous hemangiomas of the orbit usually result in painless orbital signs such as proptosis or visual loss. Orbital imaging of the lesion, which usually is a well-defined orbital mass, is demonstrated in this study. The lesion is benign and usually occurs in young to middle-aged adults. Surgical e... |

Neuro-Ophthalmic Manifestations of Brain Tumors | Steven Galetta, MD | The patient is a 45-year-old recluse found to harbor this frontal lobe mass. Remarkably, this patient had only mild bilateral optic neuropathies with visual acuities in the 20/25 range. This right disc was mildly swollen and the left mildly pale. He could not fit into the fundus camera for disc phot... |

Motility Disturbances | Rosa A. Tang, MD | Skew deviation is a vertical deviation that is not localized to any one muscle or muscle group. The deviation may be comitant or not, and intermittent or constant. Skew deviation is often defined by the company it keeps, that is, skew usually occurs in association with other brain-stem signs, and is... |

Pupillary Syndrome | Jeffrey G. Odel, MD | Intermittent dilation of the pupils may occur as a benign phenomenon in healthy young adults. In the absence of other third nerve signs, (eg, ptosis, diplopia, ophthalmoplegia), an isolated transient dilation of the pupil in an otherwise healthy adult is unlikely to represent a third nerve palsy. Tr... |

Acquired Disc Changes | Rosa A. Tang, MD | Although optociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction, they may occur in patients with chronic open-angle glaucoma. |

Acquired Disc Changes | Rosa A. Tang, MD | Although optociliary shunt vessels are venous collaterals that typically form in response to chronic venous obstruction, they may occur on a congenital basis as seen here. |

 |
Isolated Optic Neuritis/Neuropathy | Rosa A. Tang, MD | Papilledema is a term reserved for optic disc edema related to increased intracranial pressure. Fluid within the optic nerve sheath or elevation of the intraocular optic nerve head may be visible on magnetic resonance imaging studies of the head and orbit. |
| 112 |
 |
Neuro-Ophthalmic Imaging-MRI | Rosa A. Tang, MD | Aneurisms may result in neuro-ophthalmologic sign and symptoms by direct compression of the afferent or efferent systems or by the secondary effects of hemorrhage. Basilar aneurisms may result in ocular motor deficits such as a unilateral or bilateral third nerve palsy. |

 |
Acquired Disc Changes | Rosa A. Tang, MD | Optociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction. They may occur in patients following central retinal vein occlusion. |

Isolated Optic Neuritis/Neuropathy | Larry P. Frohman, MD | The patient is a 62-year-old female who presented in August 1996 with visual loss OD that she first noted as loss of her superior field in May 1996. She felt that it had been static since, and perhaps was even a little better in the week before she was seen. There was no pain, even with ocular rotat... |

Systemic Disorders With Optic Nerve and Retinal Findings | Larry P. Frohman, MD | A 42-year old woman presented with a history of severe brow pain and 4 days of progressive visual loss OD. There was no increased pain on ocular rotation. Aside from heavy menses, she denied any significant past medical history. Her examination revealed acuity NLP OD, 20/25 OS; color vision 9/10 OS;... |

Neuro-Ophthalmic Vascular Disease | Steven A. Newman, MD | Occlusion of a branch or central retinal artery may result in acute visual loss. The ophthalmoscopic findings are retinal whitening due to ischemic retina in the distribution of the occluded artery. Sparing or selective involvement of cilioretinal artery branches may occur. Patients with a central r... |

Systemic Disorders With Optic Nerve and Retinal Findings | John A. Charley, MD | A hypercoagulable state may result from deficiency of various factors involved in the clotting pathway, such as factor V. This may result in venous thrombosis and a branch or central retinal vein occlusion. Consideration for testing for an underlying coagulopathy, including the factor V deficiency, ... |

Orbital Tumors | Larry P. Frohman, MD | This 30-year-old man had a retrobulbar intraconal mass OS. The CT scans showed a heterogeneous lobulated enhancing mass, 2.2 x 1.9 x 1.8 cm. The case beautifully exhibits chorodial folds. The ultrasound showed internal reflectivity. The patient refused surgery. Pair with Images 97_60, 97_62, 97_63, ... |
