Published in Neurology, December 2004, authors D. Poggel, E. Kasten, and B.A. Sabel identify the processes and results of NovaVision VRT™ Vision Restoration Therapy™ by measuring visual field size in patients both in a control group (CG) and in an experimental group (EG). The intent of the research was to examine whether directing attention to areas of residual vision using a visuospatial cue also increases long-term neuronal plasticity and thus enhances permanent therapy outcomes. Analysis was made using Tubingen Automated Perimetry and computer-based high-resolution perimetry and detection performance in VRT.

Results: In the area of the cue, restoration of vision was significantly greater than during VRT without cueing. Cued patients showed a much more pronounced shift of the visual field border toward the blind area than that observed in the CG or in uncued regions of the EG.
