30 Rarebit Perimetry in Patients with Pituitary AdenomasStandard automated static perimetry utilizes a large field test object (Goldmann III). Because of the redundancy in the visual system, pathology affecting the visual pathways may yield normal standard automated perimetry.Rarebit; Perimetry; Pituitary Tumor; Chiasmal Syndrome; Alternative PerimetryNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
31 Surgical Management of Pituitary TumorsThe spectrum of surgically treated pituitary disease has changed radically in the past 10 years.

37 Reversible Unilateral Visual Field Defect as the Presentation of a Pituitary Adenoma and Cerebral AneurysmBitemporal hemianopsia is a well known sequelae of compression of the optic chiasm, oftentimes by a pituitary tumor. Here we present a case of a patient with unilateral visual symptoms as the presenting sign of a pituitary adenoma and a large cerebral aneurysm.Neuroimaging, Visual fields, TumorsNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu

40 Pattern Electroretinograms for the Detection of Neural Loss in Patients with Permanent Temporal Visual Field Defect from Chiasmal CompressionSeveral studies have indicated that damage to the retinal ganglion cells can be revealed by pattern electroretinogram (PERG) recordings particularly in patients with glaucoma. The pattern of neural loss in patients with previous chiasmal compression and long-standing field defects may serve as a mod...Pattern Electroretinogram; Band Atrophy of the Optic Nerve; Chiasmal Compression; Pituitary Tumor; Retinal Ganglion Cell LossNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
41 Walsh & Hoyt: Clinical Manifestations, Treatment, and Prognosis According to SiteDolichoectasia of the intracranial portions ofthe ICAs and their branches may be asymptomatic, or it may cause a variety ofsymptoms and signs that are related to the location and extent of the condition. Thus, dolichoectasia of the petrous portion ofthe ICA may produce lower cranial neuropathies, wh...Vascular Diseases; Aneurysm; Clinical Manifestations; Treatment; Prognosis; DolichoectasiaNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
42 Walsh & Hoyt: General ConsiderationsThe characteristic pituitary tumor is the adenoma. Uncommon in children, its incidence increases with age and may approach 30% in an older population. Pituitary adenomas constitute 612% of all symptomatic intracranial tumors. Most are sporadic, but pituitary adenomas are a component of multiple endo...Neoplasms; Head and Neck Neoplasms; Pituitary Gland; General ConsiderationsNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu
43 Finite Element Modeling of Chiasmal Compression: Nearer to an Understanding of Bitemporal Hemianopia?The precise mechanism of bitemporal hemianopia (BH) in the context of chiasmal compression is unknown. Previous theories have suggested that the blood supply of the crossing fibres is selectively compromised or that crossing fibres are vulnerable because they occupy the centre of the chiasm where th...Optic Chiasm; Bitemporal Hemianopia; Finite Element Modeling; Chiasmal Compression; Pituitary TumorNeuro-ophthalmology Virtual Education Library: NOVEL http://NOVEL.utah.edu

45 Walsh & Hoyt: TumorsThe most common tumors associated with aneurysms are pituitary adenomas and meningiomas. Most patients with an intracranial tumor and an aneurysm initially develop symptoms and signs from the tumor. Neuroimaging studies may identify an asymptomatic aneurysm.

46 Malignant Parasellar Lesions in ChildrenTumors of the parasellar region comprise approximately 15-20% of intracranial tumors encountered In children. The predominant members in this group are glioma and craniopharyngioma. Meningioma and pituitary tumor are less common causes.
