Abstract

Systems and methods for tracking eye movement during a diagnostic procedure include a retina imaging system configured to capture a first plurality of images of an eye and detect a presence of a fovea, an eye tracker configured to capture a second plurality of images of the eye and track a position and orientation of the eye; and a control processor configured to synchronize the first and second plurality of images, determine a time at which the fovea is detected in the first plurality of images, and determine one or more images from the second plurality of images to be classified as representative of fixation. The classified images are analyzed to determine eye fixation status during the diagnostic procedure based on eye tracking data.
