A system for improving a patient's vision, comprising: processor means, control inputs, a display or a screen, and a. means for diagnosing and monitoring a deterioration in macular vision or macular vision loss in a patient's eye, comprising means for testing and mapping a retina by scanning the retina, and b. means for augmenting the use of a preferred retinal location (PRL) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected, said means configured to obscure, fully or partially, the whole image on display except for the area associated with said preferred PRL and either i) move an image on the screen according to the gazing direction or ii) move an obscuring mask on the display to present different parts of an image on said PRL; wherein the diagnosing and monitoring means, and the augmenting means include means for applying a focalized stimulus to one location on a peripheral region of the retina at a time; and wherein the applying means include eye tracker means for measuring a gazing direction of the patient's eye and means for changing the location of the focalized stimulus on said peripheral region of the retina accordingly, so as to keep the stimulus on the same location on the peripheral region of the retina. processor means, control inputs, a display or a screen, and a. means for diagnosing and monitoring a deterioration in macular vision or macular vision loss in a patient's eye, comprising means for testing and mapping a retina by scanning the retina, and b. means for augmenting the use of a preferred retinal location (PRL) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected, said means configured to obscure, fully or partially, the whole image on display except for the area associated with said preferred PRL and either i) move an image on the screen according to the gazing direction or ii) move an obscuring mask on the display to present different parts of an image on said PRL; wherein the diagnosing and monitoring means, and the augmenting means include means for applying a focalized stimulus to one location on a peripheral region of the retina at a time; and wherein the applying means include eye tracker means for measuring a gazing direction of the patient's eye and means for changing the location of the focalized stimulus on said peripheral region of the retina accordingly, so as to keep the stimulus on the same location on the peripheral region of the retina. a. means for diagnosing and monitoring a deterioration in macular vision or macular vision loss in a patient's eye, comprising means for testing and mapping a retina by scanning the retina, and b. means for augmenting the use of a preferred retinal location (PRL) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected, said means configured to obscure, fully or partially, the whole image on display except for the area associated with said preferred PRL and either i) move an image on the screen according to the gazing direction or ii) move an obscuring mask on the display to present different parts of an image on said PRL; <EOS>
