title: Computed tomography of the visual pathways.
abstract: Many articles have discussed the anatomy and pathology of the orbits. Although this area is exquisitely visualized via computed tomography, the bulk of the visual apparatus lies behind the optic canal. A variety of pathologic conditions will manifest themselves by changes in the visual fields. This article demonstrates the normal anatomy of the visual pathways within the brain by CT scanning and correlates various changes that cause visual field defects.
