Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Vision Restoration Training (VRT)
home-based rehabilitation program which applies intense light stimulation via a PC-monitor to areas of residual vision with a duration of 1 hour daily/six days a week, subjects are asked to respond via button press upon appearance of light stimuli without eye movements
Vision Restoration Training (VRT)
Vision Exploration Training (VET)
home-based rehabilitation program to train eye movements upon visual stimuli presented via a PC-monitor with a duration of 1 hour daily/six days a week, subjects are asked to shift their gaze towards targets and respond via button press upon detection of targets
