Field Expansion for Homonymous Hemianopia
Visual field loss following a cortical lesion from stroke, brain surgery, or head trauma frequently manifests as homonymous hemianopia. Hemianopic field loss causes problems in mobility and navigation as well as reading. Patients frequently complain of bumping into obstacles on the side of the field loss and getting bruised on their arms and legs. The number of such accidents decreases with ada...
متن کاملField expansion for homonymous hemianopia by optically induced peripheral exotropia.
PURPOSE To describe a novel method for prism correction of hemianopia that provides field-of-view expansion in a convenient and functional format and to evaluate initial clinical application. METHOD To expand the upper quadrant of the field, a high power prism segment (30-40delta) is placed base-out across the upper part of the spectacle lens, on the side of the loss, at about the level of th...

متن کاملhomonymous hemianopia Scanning the visual world : a study of patients
Objectives—This study examined the scanpaths of patients with homonymous hemianopia while viewing naturalistic pictures in their original and also spatially filtered forms. Features of their scanpaths with respect to various saccade and fixation parameters were examined to determine whether they develop compensatory eye movement strategies. The eVects of various lesion parameters including loca...
متن کاملBilateral homonymous hemianopia.
Bilateral homonymous hemianopia occurred in 15 patients seen during a four-year period. Persons with this visual deficit had similarly shaped visual field defects on corresponding sides of the vertical midline for each eye, equal visual acuity which is generally normal, and normal pupil and fundus examinations. The most common causes of the bilateral posterior cerebral artery insufficency were ...
