Geniculate hemianopia: incongruous homonymous field defects in two patients with partial lesions of the lateral geniculate nucleus.
Quantitative perimetric studies in two patients with involvement of a lateral geniculate nucleus (caused by astrocytoma in one and a small arteriovenous malformation in the other) revealed strikingly incongruous defects in the contralateral homonymous fields of vision. The patterns of these hemianopias were analysed and correlated anatomically in terms of established patterns of retinal project...
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 کاملHomonymous hemianopia: challenges and solutions
Stroke is the most common cause of homonymous hemianopia (HH) in adults, followed by trauma and tumors. Associated signs and symptoms, as well as visual field characteristics such as location and congruity, can help determine the location of the causative brain lesion. HH can have a significant effect on quality of life, including problems with driving, reading, or navigation. This can result i...
متن کاملField 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 کامل[Homonymous hemianopia due to arteriovenous malformations of the brain in infancy].
INTRODUCTION Arteriovenous malformations (AVM) of the brain have a low prevalence but are responsible for a significant component of visual pathology in the young population. Vascular studies using selective angiography are necessary to identify arterial connections and venous drainage, and provide useful information for planning treatment. CLINICAL CASE A 10-year-old child with a temporo-occ...
