Claims

1. A system for improving a patient's vision, comprising means for diagnosing and

monitoring a deterioration in macular vision or macular vision loss in the patient's eye, and means for augmenting the use of a preferred retinal location (PRL) and eccentric fixation in 5 case the deterioration in macular vision or macular vision loss was detected.

2. The system for improving a patient's vision according to claim 1, wherein the means for diagnosing and monitoring a deterioration in macular vision or macular vision loss

comprise means for testing and mapping a retina by scanning the retina using a focalized 10 stimulus applied to one location on the retina at a time, and means for preventing the rest of the retina from receiving any visual stimuli.

3. The system for improving a patient's vision according to claim 1 or 2, further including eye tracker means for measuring a gazing direction of the patient's eye and means for 15 changing the location of the focalized stimulus accordingly, so as to keep the stimulus on the same location on the retina.

4. The system for improving a patient's vision according to any of the claims 1 to 3, further including means for evaluating and registering performance results for each retinal 20 location.

5. 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 25 sensitivity, crowding, reaction time, saccades, fixation stability, size of healthy area, color test, temporal JND (just-noticeable difference), orientation discrimination and/or optical distortions.

6. The system for improving a patient's vision according to any of the claims 2 to 5, 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. 5

7. The system for improving a patient's vision according to any of the claims 1 to 6,

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.

8. The system for improving a patient's vision according to claim 7, 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.

9. The system for improving a patient's vision according to any of the claims 1 to 8,

wherein the system is implemented as a stationary or portable system, comprising a display or displays, eye tracker means, processor means and control inputs.

10. The system for improving a patient's vision according to claim 9, further including a 20 tri-dimensional (3D) system comprising 3D glasses and a 3D screen, to separate the PRL stimulus to each of the two eyes.

11. The system for improving a patient's vision according to any of the claims 1 to 10, wherein the display is part of a personal computer (PC), a laptop computer, a tablet, a 25 smart phone or a television (TV).

12. The system for improving a patient's vision according to any of the claims 1 to 8, 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 30 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.

13. A method for improving a patient's vision, comprising:

a. diagnosing and monitoring a deterioration in macular vision or macular vision loss in the patient's eye; and

b. augmenting the use of a preferred retinal location (P L) and eccentric fixation in case the deterioration in macular vision or macular vision loss was detected.

14. The method for improving a patient's vision according to claim 13, wherein the step of diagnosing and monitoring a deterioration in macular vision or macular vision loss comprises:

c. testing and mapping a retina by scanning the retina using a focalized stimulus applied to one location on the retina at a time; and

d. preventing the rest of the retina from receiving any visual stimuli.

15. The method for improving a patient's vision according to claim 13 or 14, further including:

e. measuring a gazing direction of the patient's eye; and

f . changing the location of the focalized stimulus accordingly, so as to keep the stimulus on the same location on the retina, and repeating the process so as to cover part of the retina or the whole retina.

16. The method for improving a patient's vision according to any of the claims 13 to 15, further including the step of evaluating and registering performance results for each retinal location.

17. The method for improving a patient's vision according to claim 16, 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, temporal JND (just-noticeable difference), orientation discrimination and/or optical distortions.

18. The method for improving a patient's vision according to any of the claims 14 to 17, further including:

g. 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, 5 and wherein the most suitable retinal locations for PRL is defined as the location in the peripheral retina having the least deterioration.

19. 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, 10 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.

20. The device for treating patients with a retinal disease according to claim 19, further 15 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.

21. The device for treating patients with a retinal disease according to claim 19 or 20, 20 further including means for moving the image displayed according to the PRL location.
