A method for improving a patient's vision, comprising: diagnosing and monitoring a deterioration in macular vision or macular vision loss in the patient's eye; and 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. ## Claims ### Claim 1 A system for improving a patient's vision, comprising: 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; wherein the diagnosing and monitoring means, and the augmenting means, further including means for applying a focalized stimulus to one location on the retina at a time; and wherein the applying means further including eye tracker means for measuring a gazing direction of the patient's eye and means for changing the location of the focalized stimulus accordingly, so as to keep the stimulus on the same location on the retina. ### Claim 2 (depends on 1) The system for improving a patient's vision according to claim 1, wherein the system has several modes of operation including Mapping, Training, and Supervisor/Monitor, and further including means for selecting one of the modes of operation for use as desired. ### Claim 3 (depends on 2) The system for improving a patient's vision according to claim 2, further including means for defining and registering a most suitable retinal locations for PRL, based on the results of the diagnosing and monitoring a deterioration in macular vision or macular vision loss, and wherein the most suitable retinal locations for PRL is defined as the location in the peripheral retina having the least deterioration. ### Claim 4 (depends on 1) The system for improving a patient's vision according to claim 1, further including means for evaluating and registering performance results for each retinal location. ### Claim 5 (depends on 4) The system for improving a patient's vision according to claim 4, wherein the performance results for each retinal location include one or more of the following spatial and temporal parameters: visual acuity, reading acuity, reading speed, contrast sensitivity, crowding, reaction time, saccades, fixation stability, size of healthy area, color test, orientation discrimination and/or optical distortions. ### Claim 6 (depends on 1) The system for improving a patient's vision according to claim 1, wherein the means for augmenting the use of a PRL comprise means for training the patient to constantly focus the visual stimuli with the PRL and to develop a pseudo-fovea. ### Claim 7 (depends on 6) The system for improving a patient's vision according to claim 6, wherein the means for training the patient further include eye tracker means for measuring an eye gazing direction, and means for stabilizing an image on the retina based on results of the gazing direction measurements. ### Claim 8 (depends on 1) The system for improving a patient's vision according to claim 1, wherein the system is implemented as a stationary or portable system, comprising a display or displays, eye tracker means, processor means and control inputs. ### Claim 9 (depends on 8) The system for improving a patient's vision according to claim 8, further including a tri-dimensional (3D) system comprising 3D glasses and a 3D screen, to separate the PRL stimulus to each of the two eyes. ### Claim 10 (depends on 1) The system for improving a patient's vision according to claim 1, wherein the display is part of a personal computer (PC). ### Claim 11 (depends on 1) The system for improving a patient's vision according to claim 1, wherein the system is implemented as a portable system integrated in wearable goggles, and wherein the display or two displays comprise a micro-displays so devised as to present an image on the retina when the micro-display is located close to the eye, and further including a camera or two cameras attached to the goggles. ### Claim 12 A device for treating patients with a retinal disease, comprising means for mapping multiple parameters of visual performance onto various locations on the retina areas, means for stabilizing an image displayed on each location using eye tracker means, and means for training the patient to constantly focus the visual stimuli with a most suitable retinal location (PRL) and to develop a pseudo-fovea. ### Claim 13 (depends on 12) The device for treating patients with a retinal disease according to claim 12, further including means for reducing visual crowding and visual noise from the visual stimuli, means for monitoring changes of the retinal performance, and means for achieving a rehabilitation function. ### Claim 14 (depends on 12) The device for treating patients with a retinal disease according to claim 12, further including means for moving the image displayed according to the PRL location.
