Systems and Methods for Mapping and Evaluating Visual Distortions

A method for mapping visual distortions perceived by a subject, the method performed by a processor in communication with a display, the method comprising:

• displaying, at the display, a fixation target to the subject;
• receiving, at the processor, an indication corresponding to an identification of a distortion region by the subject, the distortion region having a location determined relative to the fixation target;
• displaying, at the display, an adjustable reference pattern to the subject, the adjustable reference pattern at least partially within the distortion region, the adjustable reference pattern adjustable within the distortion region and fixed outside the distortion region;
• receiving, at the processor, an indication corresponding to an adjustment by the subject of the adjustable reference pattern within the distortion region, the adjustment at least partially complementary to visual distortion perceived by the subject in the distortion region;
• determining, at the processor, a fixed reference pattern based on the adjustment of the adjustable reference pattern;
• displaying, at the display, one or more adjustable patterns to the subject, each of the one or more adjustable patterns at least partially within the distortion region, each of the one or more adjustable patterns adjustable within the distortion region and fixed outside the distortion region;
• receiving, at the processor, one or more indications corresponding to one or more adjustments by the subject of the one or more adjustable patterns within the distortion region, the one or more adjustments at least partially complementary to visual distortion perceived by the subject in the distortion region;
• and
• determining, at the processor, a distortion map based on the one or more adjustments of the one or more adjustable patterns.
