In some embodiments, a fixation point may be adjusted for a visual test presentation after a first stimulus is displayed at a first interface location on a user interface for a user. While the fixation point remains at the first interface location, one or more stimuli may be displayed on the user interface. While the fixation point remains at the first interface location, and after the display of the one or more stimuli on the user interface, a second stimulus may be displayed at a second interface location on the user interface. Vision defect information associated with the user may be generated based on feedback information indicating feedback related to the first stimulus, feedback related to the one or more stimuli, or feedback related to the second stimulus.
