Abstract:
1. A method for representing the directionality of the retina of an eye at the foveal location of said eye, comprising the steps of: A. centering an optical coherence tomograph along an axis of said eye, said axis connecting the fixation location of said retina to the center of the pupil of said eye; B. obtaining a set of optical coherence tomography sections in said eye of said retina at said foveal location; said set of sections showing at least one reference layer selected from the group of retinal pigment epithelium layer, outer limiting membrane layer or junctional complex layer in the neighborhood of said foveal location; C. geometrically determining the slope of a tangent plane to said reference layer at said foveal location; D. geometrically constructing a normal line to said tangent plane at said foveal location; E. determining the intersection of said normal line with the plane containing said pupil of said eye; F. representing the location of said intersection numerically as a set of coordinates relative to the center of said pupil of said eye; thereby indicating the inclination of said retina at said foveal location in the pupillary plane.
