Abstract

The present invention concerns a process for training the visual system of a human by presenting optical stimuli to said human, said stimuli being presented to a zone within the intact visual field of said human and to a zone outside the intact visual field of said human, the latter zone comprising a zone to be trained, thereby allowing an improvement of the vision in said latter zone, said process comprising the steps of locating and defining a zone of deteriorated vision or residual visual function or partial visual system injury (“transition zone”) within the human's visual system; defining a training area which is located within said transition zone; training the human's visual system by presenting visual stimuli to the human's visual system, the majority of said visual stimuli being presented in or near said transition zone; recording changes in the characteristics of the human's visual system; adapting the location and definition of the stimulus presentation to said transition zone according to said changes; and reiterating the previous steps continuously so as to extend the human's intact visual field into said transition zone and said transition zone into a zone…
