Method and system for measuring binocular alignment
First Claim
1. A system to determine a binocular alignment, comprising:
- a stereo display, to project visible images for a first eye and a second eye;
an accommodation optics, to modify the projected visible images according to an apparent distance;
an eye tracker, to track an orientation of the first eye and the second eye; and
a computer, coupled to the stereo display, the accommodation optics and the eye tracker, to manage a determination of the binocular alignment, wherein the eye tracker includesinfrared light emitting diodes, positioned close to a front of the system, to project infrared eye-tracking beams on the first eye and the second eye;
an infrared light source, to illuminate the first eye and the second eye with an infrared imaging light; and
infrared telescopes with infrared cameras, to detect the infrared eye-tracking beams and the infrared imaging light, reflected from the first eye and the second eye.

Abstract
Embodiments of the invention include 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 at an apparent distance; and determining an accommodative convergence of the first eye and the second eye at the apparent distance using the measured disassociated phoria. In other embodiments, a system to determine a binocular alignment comprises a stereo display, for a projection of images for a first eye and a second eye; an accommodation optics, to modify the projection of the images according to an apparent distance; an eye tracker, to track an orientation of the first eye and the second eye; and a computer, coupled to the stereo display, the accommodation optics and the eye tracker, to manage a determination of the binocular alignment.
