Study Overview
Brief Summary
This study will assess the effectiveness of a stimulus, in the blind field of hemianopsic patients, to restore the vision of patients with homonymous hemianopsia consecutive to stroke (unilateral occipital lesion). Hemianopsia occurs in 30% of strokes regardless of the cerebral localization and in 60% of stroke interesting the territory of the posterior cerebral artery.
