چکیده
purpose: to describe the clinical and photographic features of a patient who developed left homo-nymous hemianopia due to right occipital lobe hemorrhage after ingestion of sildenafil citrate (viagra). case report: a 63-year-old man was referred for acute blurred of vision in both eyes five hours after taking 50 mg viagra® (sildenafil citrate). visual field testing revealed left homonymous hemianopia and brain mri disclosed a right occipital lobe hemorrhage. conclusions: sildenafil may cause intracranial hemorrhage leading to visual disturbance and visual field defects.

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...

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 ...

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 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...

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...
