Vision Rehabilitation for Field loss
Patients with neurologic disease often have field loss, processing deficits, or ocular symptoms that can be assisted by vision rehabilitation. Scanning, sector prisms to displace images to the seeing field, and vision restoration with computer training are rehabilitation strategies proposed for patients with hemianopia. A comparative trial of scanning and prisms showed improvement in vision-related quality of life with scanning training. Scanning training can be provided by Medicare-funded occupational therapists. Stroke management guidelines include reviews of evidence for interventions for visual neglect.
