SYSTEM AND METHOD FOR SUBJECTIVE FLOATER ASSESSMENT

Abstract: an automated system for assessing a subjective severity of a patient-perceived floater in an eye of a patient includes a display screen, a patient-operated feedback device, and a floater assessment system (fas). the fas is configured to present a visual target on the display screen at a primary fixation point, and possibly at multiple secondary fixation points arranged radially around the primary fixation point. the fas also receives feedback signals from the patient-operated feedback device in response to an activation thereof by the patient. the feedback signals are indicative of a location and possible size of the patient-perceived floater in the patient's field of vision. additionally, the fas calculates a numeric floater severity score using the feedback signals that quantifies the subjective severity of the floater(s).
