MRI Findings in Optic Nerve and Chiasmal Glioma in Childhood | Multiple cases of optic pathway gliomas are demonstrated using MRI imaging. The optic pathway gliomas are identified at multiple points in the optic pathways. Figure 1 : Patient 1: Axial orbital MRI (T1 postcontrast with fat suppression) showing thickening and enhancement of the right optic nerve a... | Jason Peragallo, MD; Valérie Biousse, MD |

Nonfunctiong Pituitary Adenoma with Chiasmal Compression | This is a case of large non-functioning pituitary adenoma with mass effect on the optic chiasm inducing loss of optic nerve fibers and subsequent visual field. Figure 1: Fundus photographs demonstrating bilateral temporal optic nerve head pallor Figure 2: Humphrey visual fields demonstrating a bitem... | William Pearce, MD; Valérie Biousse, MD |

Junctional Scotoma from a Sellar Mass | This is a case of a 55-year-old woman presenting with gradual painless vision loss in both eyes. Although visual acuity was 20/20 in both eyes, there was a left relative afferent pupillary defect and diffuse pallor of both optic nerves (Figure 1). Visual fields (24-2 SITA-Fast) showed a temporal def... | Jonathan A. Micieli, MD; Valérie Biousse, MD |

Large Right Hypophyseal Aneurysm Causing a Junctional Scotoma | Right, multi-lobulated superior hypophyseal artery aneurysm measuring 1.6 x 1.2 x 2.2 cm with 6 mm neck causing a right junctional scotoma . Images from a brain CT with contrast, a brain CT angiography with contrast, cerebral angiogram, Humphrey visual fields and ocular fundus photographs are includ... | Laurel N. Vuong, MD; Valérie Biousse, MD |

Sellar Aneurysm with Chiasmal Compression | This is a case of aneurysm of the internal carotid artery, invading the sella and complicated by chiasmal compression and bitemporal hemianopia. Figure 1 : Humphrey visual fields (gray scale and pattern deviations) Figure 2a : T1-weighted axial brain MRI (1): well defined circular intracerebral mass... | Rabih Hage, MD; Valérie Biousse, MD |

Checkboard Visual Field Loss Due to Bilateral Homonymous Hemianopsias | A 70-year-old man with vascular risk factors was seen for assessment of sudden visual field loss in both eyes. His examination showed: visual acuity: 20/20 OD and 20/25 OS; pupils: equal with no relative afferent pupillary defect; color vision: 14/14 plates correct OU; anterior segment exam: normal ... | Rahul A. Sharma, MD, MPH; Valérie Biousse, MD |

Retrograde Trans-Synaptic Degeneration from a Longstanding Occipital Lobe Tumor | This is an illustrated guide that (1) discusses the localization of paracentral homonymous hemianopic scotomatous visual field defects and (2) discusses the concept of trans-synaptic retrograde degeneration. A 43-year-old woman was assessed for longstanding blurred vision in both eyes. Her examinati... | Rahul A. Sharma, MD, MPH; Valérie Biousse, MD |

Optic Nerve Head Granuloma from Sarcoidosis | We present a case of optic neuropathy with optic nerve head granuloma as the presenting sign of neurosarcoidosis. Initial patient presentation was notable for a chronic cough and worsening of vision in the left eye. Subsequent imaging revealed multiple brain lesions and the presence of a subcarinal ... | Nithya Shanmugam; Valerie Biousse |
