Patent attributes
Systems and methods for performing a visual field test of a patient are described. One example method for performing the visual field test of the patient using a visual field testing device having a refractive correction element, a patient support, and a motor operably attached to one of the refractive correction element or the patient support includes positioning the patient's head relative to the device using the patient support. An image showing the position of the eye relative to the refractive correction element is collected. The relative displacement of the eye with respect to the refractive correction element is determined based on the collected image. The motor is actuated in a manner to reduce the determined displacement. A series of test stimuli is displayed to the patient's eye and responses to the test stimuli are received from the patient. The responses are analyzed to make an assessment of the patient's visual field.
