Visual and functional rehabilitation platforms including a set of equipment as per the guidelines and recommendations laid down by the Argus II system developer though which serial rehabilitation sessions would be completed to improve functional vision. The visual rehabilitation process is followed intermittently in visual rehabilitation unit and functional rehabilitation set up. Things to consider include contrast modifications, lighting evaluation and contrast evaluation when trainings are provided. It is also recommended to similarly customize the environment of the patients' home. (A) The functional rehabilitation unit where subjects are trained to undertake target localization tasks on a magnet board, touch items, focus of contrasts and edges detection with the system ON, and to interact with the customized environment by locating and working with the microwave oven, fridge, locating black and white bowls, plates and table cloth, etc. (B) The visual rehabilitation setup comprising the grating visual acuity task on computer monitors, visual rehabilitation kit provided by the developer and the line-task in which the subject needs to track the path of light-emitting target on the floor.
