Ocular Manifestations of Systemic Disorders | Rosa A. Tang, MD | Systemic lymphoma may occur in the orbit and may involve the lacrimal gland. Patients usually present with a painless, progressive proptosis or a mass. CT scan usually demonstrates an irregularly shaped lesion conforming to the globe or lacrimal fossa, and bone erosion is not usually found. Pair wit... |

 |
Motility Disturbances | Rosa A. Tang, MD | Cyclical oculomotor paresis may occur in patients as an intermittent phenomenon, with a paretic phase and diplopia and intervals that are nonparetic. The history and examination are classic for the disorder. Pair with Images 95_18 and 95_20. |

 |
Ocular Manifestations of Systemic Disorders | Rosa A. Tang, MD | Thyroid eye disease may cause proptosis and extraocular muscle enlargement that may be seen on orbital imaging studies. In general, coronal images allow the best visualization of the extraocular muscle enlargement. Pair with 94_44 and 94_46. |

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. |

Motility Disturbances | Larry P. Frohman, MD | This man had a posttraumatic right sixth nerve paresis. Image 94_66 demonstrates the adduction deficit that the Botox induced. |

Neuro-Ophthalmic Vascular Disease | Larry P. Frohman, MD | This 32-year-old woman was referred with a history of 4 days of loss of vision OD. She had a history of manic depressive illness and IV drug abuse; she had been HIV tested 4 weeks before and was negative. She said she last injected cocaine 5 days before being seen, the night before she awoke with th... |

Chiasmal Syndromes | Larry P. Frohman, MD | A 50-year-old right-handed woman with no significant past medical history underwent liposuction on her abdomen, hips, and thighs under general anesthesia. Her height and weight were 167 cm and 63 kg, respectively. Subcutaneous fat was injected with 2.5 L of 0.05% xylocaine and 1:10,000,000 epinephri... |

Systemic Disorders With Optic Nerve and Retinal Findings | Larry P. Frohman, MD | This 74-year-old asthmatic male had acute visual loss OS while watching the Super Bowl in 1994. He was seen the next day by a retina specialist, who noted that his optic disc was normal and referred the patient to a neuro-ophthalmologist, who evaluated him about 40 hours after his visual loss. He wa... |

Systemic Disorders With Optic Nerve and Retinal Findings | Larry P. Frohman, MD | This 25-year-old man presented to the eye service with a history of 3 days of decreased vision OD. His past medical history was unremarkable. His examination showed acuities of 20/25 OU, with intact color plates, a 0.3 log unit of RAPD OD, and an inferior arcuate scotoma. The photos (Images 95_42, 9... |

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... |

Chiasmal Syndromes | Shlomo A. Dotan, MD | A 52-year-old, morbidly obese man with a past medical history that included ischemic cardiac disease with a history of angioplasty, COPD, hypertension, and NIDDM, presented with a severe headache. The next day he had a frozen OD, complete right ptosis, and an unreactive middilated right pupil with V... |

Isolated Congenital Optic Disc Anomalies | Thomas R. Wolf, MD | This optic disc displays multiple drusen. Note the pseudopapilledema here. One can differentiate this from true papilledema in that there is no obscuration of the vessel by the peripapillary nerve fiber layer as they cross the disc margin. This photograph was taken with barrier filters in place, but... |

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 Vascular Disease | Mark L. Moster, MD | Neovascularization of the iris may form in response to an ischemic disease of the retina, such as diabetic retinopathy. Carotid artery occlusion may result in ocular ischemia that may induce neovascularization.This is a dramatic image of iris neovascularization. |
