Orbital Tumors | 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... | Cavernous Hemangioma |

 |
Neuro-Ophthalmic Imaging-CT Scan | Idiopathic orbital pseudotumor is an inflammatory disorder that may effect any part of the ocular anatomy. The site of inflammation determines the nomenclature. For example, involvement of the sclera is referred to as scleritis. And involvement of one or more of the extraocular muscles is referred t... | Myositis; Orbital Inflammation |

Ocular Manifestations of Systemic Disorders | Thyroid eye disease is the most common cause of unilateral or bilateral proptosis in the adult patient. Other signs of thyroid eye disease should be sought, including lid retraction, inferior scleral show, and lid lag. Patients with markedly asymmetric or strictly unilateral proptosis should probabl... | Thyroid Disease; Thyroid Eye Disease; Myopathy; Proptosis; Periorbital Edema; Lid Retraction; CT |

Neuro-Ophthalmic Imaging-MRI | Axial view of Arnold-Chiari malformation on a patient with downbeat nystagmus. Note the presence of the cerebellar tonsils posterior to the caudal medulla. In addition to downbeat nystagmus, Arnold-Chiari malformations can sometimes lead to increased intracranial pressure and papilledema. | Arnold-Chiari Malformation; Chiari Malformation; Inferior Tonsillar Herniation; Downbeat Nystagmus |

Neuro-Ophthalmic Imaging-MRI | Sagittal view of Arnold-Chiari malformation on a patient with downbeat nystagmus. The compression of the cervicomedullary junction is clearly depicted in the sagittal view. | Arnold-Chiari Malformation; Chiari Malformation; Inferior Tonsillar Herniation; Downbeat Nystagmus |

Neuro-Ophthalmic Imaging-CT Scan | This is a patient with trauma leading to enucleation, with swelling years later over the implant. This is a presumed chronic abscess between orbit and dura. | Orbital Abscess |

 |
Isolated Optic Neuritis/Neuropathy | Papilledema usually results in bilateral optic disc edema without visual loss. The blind spot may enlarge initially, but progressive visual field loss may occur with chronic optic disc edema. Asymmetric or frankly unilateral optic disc edema may occur due to structural disc fractures that prevent th... | Pseudotumor Cerebri/Papilledema; Edema |

 |
Isolated Optic Neuritis/Neuropathy | Papilledema is a term reserved for optic disc edema related to increased intracranial pressure (eg. Papilledema, sixth nerve palsy, headache), a normal neuroimaging study, and an elevated opening pressure with normal cerebrospinal fluid contents. | Pseudotumor Cerebri/Papilledema; Edema |
