Vision Restoration Training in Glaucoma

visual stimuli repetitively presented to stimulate areas of residual vision. The training consists of luminance increment stimuli similar to perimetry and the task isa simple detection task (pressing a key whenever a target stimulus was detected).

the stimulus is a line segment (bar) which is always presented within the central ±5° visual field in one of four possible random orientations: horizontal, vertical, oblique to the right or oblique to the left. If the patient has visual field defects in this central area, 80% of the stimuli are presented in the intact part of the training region. The task is to identify the orientation of the line segment and press, as fast as possible, one of 4 assigned buttons on the keyboard.
