Abstract
A system for testing visual fields comprising a display for presenting a visual stimulus and an eye tracker for tracking movement of at least one of a patient's eyes to determine its position in three dimensions without requiring the patient to wear any tracking equipment. A computer controls the position of the stimulus on the display and causes it to move by an amount that is a function of the tracked three-dimensional position of the patient's eye and a visual field position that is to be tested. Changes to the position of the stimulus and any corresponding tracked eye movement are used to assess the patient's visual field.
