title: Malignant gliomas of the optic nerve pathways.
abstract: We compared the clinical course and histopathologic findings in five patients with malignant gliomas originating from the optic nerve pathways with those in previously reported cases to elucidate further the clinical features of this tumor and facilitate future diagnoses. Patients with malignant optic nerve pathway gliomas had unilateral or bilateral visual dysfunction, which was often accompanied by periorbital discomfort in an otherwise asymptomatic adult. Regardless of origin, the clinical course invariably was bilateral blindness rapidly followed by death. Occasionally, the diagnosis was made preoperatively and was confirmed by surgical exploration and biopsy.
