The prognosis for vision in most patients with pseudotumor cerebri is excellent; however, visual loss, which is the only serious complication, may occur either early or late in the course of the disease. A group of 57 patients was followed up five to 41 years with visual fields, visual acuity, and fundus photographs. Blinding visual loss or severe visual(More)
Disagreement exists concerning the natural history and treatment of chiasmatic gliomas (CG) of childhood. We reviewed our experience in 21 cases of surgically verified CG with a median age of 4 years at time of diagnosis, followed for a median of 5.3 years (range 3-14.8 years). Initial treatment included radiation therapy (RT) in 18 patients, chemotherapy(More)
Pituitary function was evaluated before and after supervoltage radiotherapy for a pituitary adenoma in 35 patients; 22 had had prior surgical treatment, and 13 had not. For comparison, pituitary function was also followed concurrently in another 10 patients whose pituitary adenomas were treated surgically, but who did not receive subsequent radiotherapy.(More)
Three patients with dural arteriovenous malformations contiguous with the cavernous sinus had marked worsening of their neuro-ophthalmic symptoms. Such clinical deterioration has been attributed traditionally to increased blood flow through the malformations into the superior ophthalmic vein. However, arteriography in all three patients and magnetic(More)
BACKGROUND AND PURPOSE Endovascular transvenous embolization has been advocated as the treatment technique for dural carotid cavernous fistulas (dCCFs). Most centers use platinum coils primarily. The purpose of this study was to evaluate the technical aspects, efficacy, and safety of transvenous n-butyl cyanoacrylate (n-BCA) infusion in dCCFs as a primary(More)
Fifteen patients with clinical presentations compatible with idiopathic inflammatory orbital pseudotumor were examined by CT and MR imaging to determine if MR could add specificity to the CT appearance of this entity. MR was performed on a 1.5 T system, using surface-coil and head-coil techniques. Idiopathic pseudotumor was confirmed in nine patients on the(More)
Thirteen patients with delayed radiation injury to the optic nerves and chiasm were treated with hyperbaric oxygen (HBO) and corticosteroids. These patients experienced painless, abrupt loss of vision in one (6 patients) or both (7 patients) eyes between 4 and 35 months after receiving radiation doses of at least 4500 cGy to the region of the chiasm.(More)
The etiology of anterior ischemic optic neuropathy (AION), when not associated with giant cell arteritis, is usually unknown. Clinical, pathologic, and experimental studies have not determined a cause. The optic disc appearance in both the involved and normal fellow eye was studied in 51 patients with acute nonarteritic AION. The number of discs (both(More)
OBJECTIVE To determine the incidence of positive neuroradiologic studies in consecutive patients with glaucoma associated with normal intraocular pressure and to compare the psychophysical and clinical characteristics of these eyes with eyes with disc cupping associated with intracranial masses. DESIGN Retrospective case-controlled study. PARTICIPANTS(More)
