Imaging evaluation of the optic nerve and visual pathway including cranial nerves affecting the visual pathway.

The radiologic investigation of the optic pathways has an integral part in the diagnostic evaluation of diverse lesions, such as inflammatory disease, vascular disorders, and benign and malignant tumors that afflict the optic pathways. These radiologic methods consist principally of computed tomography and magnetic resonance imaging, and, in vascular lesions, magnetic resonance angiography and conventional angiography.
