Problems solved by technology

[0006] Current perimetry techniques are costly and often inconvenient for patients
Therefore, it is difficult to administer a series of perimetry tests to patients in a short period of time, which limits the ability to characterize the patient's vision at the time
Additionally, patients often need to be instructed to keep their head still, which can cause discomfort due to postural maintenance and reduce fixation accuracy
Additionally, individual test results may not be as reliable as desired, compromising the validity of the tests administered

Abstract

Methods and systems for assessing a visual field of a person are provided. Information can be presented to a person undergoing a visual field testing in a manner that utilizes the person's natural tendency to look at an object that is displayed so that it attracts the person's attention. A fixation target can be displayed on a display viewed by a user. Once it is determined that the user has viewed the fixation target and the person's eye(s) location is determined, a test target is displayed on the display in a location corresponding to a location on the user's visual field. The test target isdetermined to be either detected or missed based on user input acquired as the user is viewing the display.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 62 / 586,151, filed November 14, 2017, entitled "SYSTEMSAND METHODS FOR VISION ASSESSMENT," the entire disclosure of which is incorporated by reference here. technical field [0003] Systems and methods for visual field analysis for diagnosing and monitoring visual disorders including glaucoma are provided. Background technique [0004] Many disorders of the visual system manifest first as selective geographic loss of vision at one or more locations. Screening for disease, monitoring progress during treatment, and developing new treatments depend on the quality assessment of visual field deficits in patients. Visual field analysis (also called "perimetry") involves measuring how well a patient sees at different locations on their retina. [0005] Glaucoma is a progressive disease in which peripheral vision is lost due to damage to retinal ganglion ...
