Video game to monitor retinal diseases

A computer-implemented method for testing macular visual acuity, comprising:

• displaying a fixation location indicator on a display of a computing device configured for fixation thereon by a user;
• simultaneously and briefly displaying on the display a fixation pattern at the location of the fixation location indicator and at least two pericentral patterns spaced apart from the fixation pattern, wherein one of the pericentral patterns is a correct choice pericentral pattern that is different from the other of the pericentral patterns;
• receiving input from the user via a user input device indicating a selection of one of the pericentral patterns;
• determining whether the user selected the correct choice pericentral pattern;
• and
• recording whether the user selected the correct choice pericentral pattern in a data storage.

A system for testing macular visual acuity, comprising:

• a display;
• a user input device;
• and
• a computer coupled to the display and the user input device, and configured to:
• simultaneously and briefly display on the display a fixation pattern and at least two pericentral patterns, wherein one of the pericentral patterns is a correct choice pericentral pattern that is different from the other of the pericentral patterns;
• receive input from the user via the user input device indicating a selection of one of the pericentral patterns;
• and determine whether the user selected the correct choice pericentral pattern.

A non-transitory computer-readable medium encoded with computer executable instructions, which when executed, performs a method comprising:

• displaying a first set of objects on a display of a computing device, the first set of objects including at least three objects, exactly one object in the first set objects being different from the other of the objects in the first set, wherein recognition of the difference between the one different object and the other of the objects is indicative of a user's visual acuity;
• receiving input from the user via a user input device of the computing device indicating a selection of one of the objects in the first set of objects;
• determining whether the user correctly selected the one different object from the first set of objects;
• and
• assessing the user's visual acuity based on the selections of the user.

A computer-implemented method for providing a video game for testing macular visual acuity, the method comprising:

• testing central visual acuity by executing a plurality of central visual acuity rounds of the video game, each central visual acuity round comprising:
• displaying at least three central acuity targets on a display of a computing device, one of the at least three central acuity targets being different from the other of the central acuity targets, wherein recognition of the difference between the one different central acuity target and the other central acuity targets is indicative of a user's central visual acuity;
• receiving a selection of one of the central acuity targets from the user via a user input device of the computing device;
• determining whether the user correctly selected the one different central acuity target from the central acuity targets;
• and
• assessing the user's central visual acuity based on the selection of the user;
• testing pericentral visual acuity by executing a plurality of pericentral visual acuity rounds of the video game, each pericentral visual acuity round comprising:
• displaying a fixation location indicator on the display of the computing device configured for fixation thereon by a user;
• simultaneously and briefly displaying on the display a fixation target at the location of the fixation location indicator and at least two pericentral acuity targets spaced apart from the fixation target, wherein one of the pericentral acuity targets is a correct choice pericentral acuity target that is different from the other of the pericentral acuity targets, the correct choice pericentral acuity target being positioned relative to the fixation target such that perception of the correct choice pericentral acuity target is indicative of the user's visual acuity at a location on an acuity map;
• receiving a selection of one of the pericentral acuity targets from the user via the user input device;
• determining whether the user selected the correct choice pericentral acuity target;
• and
• recording whether the user selected the correct choice pericentral acuity target in a data storage;
• and
• generating a visual acuity map based on the user's selections during the plurality of central acuity and pericentral acuity rounds, wherein in the visual acuity map is divided into a plurality of locations, and each of the plurality of locations is tested by at least one of the central acuity or pericentral acuity rounds of the video game.
