US10209773

1. A method of assessing a vision performance of a patient using a computing device programmed to execute a plurality of programmatic instructions, comprising (12) (5)

presenting, via the computing device, a first set of visual and/or auditory stimuli, wherein presenting the first set of visual stimuli comprises presenting at least a digital image to the patient via a display screen;

monitoring a first plurality of reactions of the patient using at least one of the computing device or a separate hardware device;

presenting, via the computing device, a second set of visual and/or auditory stimuli, wherein presenting the second set of visual stimuli comprises presenting at least a digital image to the patient via the display screen;

monitoring a second plurality of reactions of the patient using at least one of the computing device or a separate hardware device; and

based upon said first plurality of reactions and second plurality of reactions, determining quantitative values representative of the patient's field of view, visual acuity, ability of the patient to track multiple stimuli, visual endurance and visual detection.

2. The method of claim 1 further comprising generating a single vision performance value representative of an aggregation of the field of view, the visual acuity, the ability of the patient to track multiple stimuli, the visual endurance and the visual detection. (0)

3. The method of claim 1 wherein the first plurality of reactions comprises at least one of rapid scanning data, saccadic movement data, blink rate data, fixation data, pupillary diameter data, and/or palpebral fissure distance data. (0)

4. The method of claim 1 wherein the second plurality of reactions comprises at least one of rapid scanning data, saccadic movement data, fixation data, blink rate data, pupillary diameter data, speed of head movement data, direction of head movement data, heart rate data, motor reaction time data, smooth pursuit data, palpebral fissure distance data, degree and rate of brain wave activity data, and/or degree of convergence data. (0)

5. The method of claim 1 wherein the hardware device comprises at least one of a camera configured to acquire eye movement data, a sensor configured to detect a rate and/or direction of head movement, a sensor configured to detect a heart rate, or an EEG sensor to detect brain waves. (0)

6. The method of claim 1 wherein the quantitative values representative of the patient's field of view comprises data representative of a quality of the patient's central vision and data representative of a quality of the patient's peripheral vision. (0)

7. The method of claim 1 wherein the quantitative values representative of the patient's visual acuity comprises data representative of a quality of the patient's reaction time to said first set of visual and/or auditory stimuli. (0)

8. The method of claim 1 wherein the quantitative values representative of the patient's visual acuity comprises data representative of a quality of the patient's precise targeting of said first set of visual stimuli and wherein said quality of the patient's precise targeting of said first set of visual stimuli is based on a position of the patient's physical response relative to a position of the first set of visual stimuli. (0)

9. The method of claim 1 wherein the quantitative values representative of the patient's ability of the patient to track multiple stimuli comprises data representative of a quality of the patient's ability to simultaneous track multiple elements in the second set of visual stimuli. (0)

10. The method of claim 1 wherein the quantitative values representative of the patient's visual endurance comprises data representative of a decrease in the patient's reaction time over a duration of presenting the first set of visual and/or auditory stimuli. (0)

11. The method of claim 1 wherein the quantitative values representative of the patient's visual endurance comprises data representative of an improvement in the patient's reaction time over a duration of presenting the second set of visual and/or auditory stimuli after a rest period. (0)

12. The method of claim 1 wherein the quantitative values representative of the patient's visual detection comprises data representative of to what extent the patient sees the first set of visual stimuli. (0)

13. The method of claim 1 wherein the quantitative values representative of the patient's visual detection comprises data representative of to what extent the patient can discriminate between similar colored, contrast, or shaped objects in the first set of visual stimuli. (0)

14. A method of assessing a vision performance of a patient using a computing device programmed to execute a plurality of programmatic instructions, comprising (5) (5)

presenting, via a display on the computing device, a first set of visual stimuli, wherein presenting the first set of visual stimuli comprises presenting at least a digital image to the patient on the display and wherein the first set of visual stimuli comprises a first plurality of visual elements that move from a peripheral vision of the patient to a central vision of the patient on the display;

monitoring a first plurality of reactions of the patient using at least one of the computing device or a separate hardware device;

presenting, via the display on the computing device, a second set of visual stimuli, wherein presenting the second set of visual stimuli comprises presenting at least a digital image to the patient via the display and wherein the second set of visual stimuli comprises a second plurality of visual elements that appear and disappear upon the patient physically touching said second plurality of visual elements on the display;

monitoring a second plurality of reactions of the patient using at least one of the computing device or said separate hardware device; and

15. The method of claim 14 wherein at least a portion of the first plurality of visual elements have sizes that decrease over time. (0)

16. The method of claim 14 wherein at least a portion of the first plurality of visual elements have a speed of movement that increases over time. (0)

17. The method of claim 14 wherein, over time, more of the first plurality of visual elements simultaneously appear on the display of said computing device. (0)

18. The method of claim 14 wherein a third plurality of visual elements appear concurrent with said second plurality of visual elements, wherein the third plurality of visual elements appear different than the second plurality of visual elements, and wherein, if the patient physically touches any of said third plurality of visual elements, the quantitative value representative of the patient's visual acuity is decreased. (0)

19. The method of claim 14 further comprising presenting, via the display on the computing device, a third set of visual stimuli, wherein the third set of visual stimuli comprises a fourth plurality of visual elements; monitoring a third plurality of reactions of the patient using at least one of the computing device or said separate hardware device; and based upon said first plurality of reactions, second plurality of reactions, and third plurality of reactions determining quantitative values representative of the patient's field of view, visual acuity, ability of the patient to track multiple stimuli, visual endurance and visual detection. (1) (0)
