Ocular Manifestations of Systemic Disorders | Larry P. Frohman, MD | A 17-year-old girl had undergone multiple superficial biopsies of the orbit for what was felt to be refractory orbital pseudotumor. Initial evaluation revealed the saddle-nose deformity, which the patient confirmed was acquired. More extensive biopsy was consistent with lymphomatoid granulomatosis. ... |

Ocular Manifestations of Congenital/Inherited Diseases | Jacqueline A. Leavitt, MD | This 22-year-old woman has neurofibromatosis, type 2. Acuity, color plates, pupillary responses, slit-lamp examination, IOP, fields, and funduscopy are all normal. There is a 3 mm proptosis OS. The patient has recently undergone gamma knife for the acoustic tumor, and she has residual facial nerve p... |

Motility Disturbances | Rosa A. Tang, MD | Traumatic damage to the third cranial nerve may result in aberrant regeneration of fibers that innervate the eyelid, pupil, or extraocular muscles. For instance, there may be lid retraction in attempted downgaze. Any combination of aberrant activation of third nerve-innervated structures may occur, ... |

Isolated Congenital Optic Disc Anomalies | Thomas R. Wolf, MD | An optic pit is a small defect in the optic disc that may be asymptomatic in isolation. Patients may develop an associated serous detachment of the macula. The condition is usually unilateral but may be bilateral. A fluorescein angiogram may demonstrate the serous detachment, and laser photocoagulat... |

|
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... |

Ocular Manifestations of Systemic Disorders | Rosa A. Tang, MD | Myasthenia gravis should be considered in any patient with painless, pupil-spared, nonapoptotic ophthalmoplegia. It may mimic any ophthalmoparesis. Involvement of the medical rectus may result in a pseudointernuclear ophthalmoplegia. Pair with 96_23 and 96_25. |

Ocular Manifestations of Congenital/Inherited Diseases | Mitchell J. Wolin, MD | Patients with olivopontocerebellar atrophy may exhibit signs of ocular motor deficits, such as ocular motor apraxia or cerebellar eye signs, and peripheral pigmentary retinopathy and optic atrophy. Pair with 94_55. |

Isolated Optic Neuritis/Neuropathy | Rosa A. Tang, 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. |

Optic Disc Drusen With Autofluorescence | Thomas R. Wolf, MD | This photograph of optic disc drusen demonstrates autoflourescence with flourescein barrier filters in place. Imaging: flourescein barrier filters. |

|
Isolated Congenital Optic Disc Anomalies | Thomas R. Wolf, MD | Benign tumors of blood vessels (hemangiomas) may occur on the optic nerve and may mimic optic disc edema. Disease/Diagnosis: Optic Nerve Hemangioma. |

Motility Disturbances | Don Bienfang, MD | This patient displays a posttraumatic left fourth nerve palsy sustained after having struck her head on the dashboard. |

|
Isolated Optic Neuritis/Neuropathy | Rosa A. Tang, MD | Papilledema in pseudotumor cerebri may result in adjacent choroidal or retinal folds. |

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... |

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 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. |
