A system for assessment of a visual field of a user, the system comprising: computing hardware configured for communication with a head-mountable device, the computing hardware configured to perform operations comprising: causing display, on the head-mountable device, of a first fixation target, the first fixation target being one of a plurality of fixation targets; determining whether a fixation task associated with the first fixation target has been completed by the user; based at least on determining that the fixation task associated with the first fixation target is completed, identifying a position of at least a portion of at least one eye of the user, based at least on the identifying the first position, causing display, on the head-mountable device, of a first test target, the first test target being one of a plurality of test targets, the first test target displayed at a first location, the first location corresponding to one of a plurality of locations in the visual field of the user, others of the plurality of test targets each corresponding to at least one other of the plurality of locations; determining whether the user has detected the first test target at the first location; and collecting data related to the determining of whether the user has detected the first test target at the first location; automatically iteratively performing the causing display of the first fixation target, determining whether the fixation task associated with the first fixation target has been completed by the user, identifying the position, causing display of the first test target, and determining whether the user has detected the first test target at the first location, for each of at least a portion of the plurality of fixation targets and corresponding ones of the plurality of test targets until a certain termination condition is met; and providing information related to a result of the visual field assessment of the user based at least on the collected data from the iterative performance of the operations. causing display, on the head-mountable device, of a first fixation target, the first fixation target being one of a plurality of fixation targets; determining whether a fixation task associated with the first fixation target has been completed by the user; based at least on determining that the fixation task associated with the first fixation target is completed, identifying a position of at least a portion of at least one eye of the user, based at least on the identifying the first position, causing display, on the head-mountable device, of a first test target, the first test target being one of a plurality of test targets, the first test target displayed at a first location, the first location corresponding to one of a plurality of locations in the visual field of the user, others of the plurality of test targets each corresponding to at least one other of the plurality of locations; determining whether the user has detected the first test target at the first location; and collecting data related to the determining of whether the user has detected the first test target at the first location; automatically iteratively performing the causing display of the first fixation target, determining whether the fixation task associated with the first fixation target has been completed by the user, identifying the position, causing display of the first test target, and determining whether the user has detected the first test target at the first location, for each of at least a portion of the plurality of fixation targets and corresponding ones of the plurality of test targets until a certain termination condition is met; and providing information related to a result of the visual field assessment of the user based at least on the collected data from the iterative performance of the operations. <EOS>
