homonymous 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 ...
متن کاملCan visual function be restored in patients with homonymous hemianopia?
It can be argued that vision is the major sensory input into the human brain, by virtue of the fact that about half of all aVerent fibres projecting to the brain are from the eye and by the sophistication of the neural systems controlling visual processing. Brain damage disrupts these complicated processes, resulting in severe visual impairments including hemianopia. Patients with hemianopia co...
