Claim 0:
1. A method to determine a binocular alignment, the method comprising:
measuring a disassociated phoria of a first eye and a second eye of a patient by presenting non-fusible images with a first apparent distance vergence by presenting a target for a first eye and presenting a disassociated targetless image for the second eye with a first apparent distance vergence, and
measuring the disassociated phoria of at least one of the first eye and the second eye in response to the presenting of non-fusible images, using an eye tracker;
determining an accommodative convergence of the first eye and the second eye by presenting fusible images for the first eye and the second eye with the first apparent distance vergence, corrected with the measured disassociated phoria and tracking an adjustment of the first eye and the second eye in response, using the eye tracker;
repeating the measuring the disassociated phoria with a second apparent distance vergence;
repeating the determining the accommodative convergence with the second apparent distance vergence; and
constructing a ratio of a difference of the determined accommodative convergence at the first distance minus at the second distance, divided by a difference of an accommodative response at the first distance minus at the second distance.
