Abstract
A method and apparatus for fixation measurement includes projecting, by a projection apparatus, a target image onto one or more eyes of a patient and capturing, by one or more image sensing devices disposed conjugate to the one or more eyes, a reflected image reflected from the one or more eyes in response to the target image, wherein the reflected image includes information indicating the fixation of the one or more eyes.
