Approaches to medical rehabilitation of patients with post-stroke hemianopsia

Visual impairment is reported in about a third of stroke patients. It significantly reduces patients' quality of life and leads to maladjustment in everyday life and disability. There are three main areas of medical rehabilitation for patients with visual impairments after a stroke: restoration of visual fields (restorative therapy), modification of behavior to compensate for lost visual function (training of compensatory capabilities), and replacement of a visual defect using devices or external modifications (replacement therapy). Data on their effectiveness are contradictory. Audiovisual stimulation is a promising direction. Attempts are made to use neuromodulation techniques to restore visual function after a stroke. Further prospects in this area are associated with the introduction of modern neurotechnologies.
