La mise en place de zone rétinienne préférentielle. Partie II : Quand ? Où ? Pourquoi s'installe-t-elle ?

The new visual message must be integrated into the most suitable cerebral locations for low spatial frequencies, damaged forms, messages transmitted by retinal rods, and finally global visual perception. It must favor the peri-personal space and near vision. These elements correspond to the new visual surroundings of the visually impaired. We believe that these data are better processed if they are transmitted by the lower and left visual fields. The rehabilitation program must take into account the above considerations. If the vision therapist orients the PRL location using eccentric view training or by having the patient wear a prism, he must keep in mind that the partially sighted's activities of daily life are the most important. At first, the superior side position, which leaves the field open to a maximum of visual tasks, must be trained, followed by the right position. Of course, when this localization has already been achieved, it must be respected.
