Abstract
One aspect of the disclosure includes a method to assess vision function. In one embodiment, the method comprises providing a sequence of test images on a display (106) to a test subject (102) during a stimulus interval and providing a response pattern image for each of the sequence of test images during a response interval after the stimulus interval. Each of the sequence of test images includes multiple stimulus patterns (304, 306) arranged around a fixation target (302). The response pattern image includes multiple response targets (320), each of which corresponds to a location of each of the multiple stimulus patterns (304, 306). One (304) of the multiple stimulus patterns (304, 306) differs. An assessment of a vision function of the test subject (102) is based on a selection by the test subject of one of the multiple response targets (320) that the test subject indicates corresponds to a location of the multiple stimulus pattern that differs (304). A corresponding vision testing system (100) is disclosed as well.
