Claim One:
1. A method of determining the location of the fovea within an image of an eye, said image being obtained with an optical coherence tomography (OCT) system, said OCT system including a light source generating a beam of light, a sample arm a reference arm and a detector for measuring light combined from the sample and reference arms, said method comprising the steps of: scanning the beam of light over a region of the eye; combining the light from the sample and reference arms; measuring the combined light to generate three dimensional image information; analyzing the image information to determine the location of the fovea within the image, said analyzing step being performed by evaluating a location dependent image quantity that reaches an extremum as the likelihood of that location being at or near the center of the fovea increases; and storing or displaying the determined foveal location.
