Enhanced optical coherence tomography for anatomical mapping

A method for generating a partial fundus image from a 3-D intensity data set corresponding to the distribution of reflection sites within the eye acquired by scanning the eye with an optical coherence tomographic (OCT) device, said method comprising the steps of:

• obtaining a 3-D intensity data set corresponding to the distribution of reflection sites within the eye by scanning the eye with an optical coherence tomographic (OCT) device;
• identifying a reference surface within the eye from the 3-D data set;
• processing the intensity data along a Z-axis extending between the reference surface and a selected range from that surface in order to assign a single representative intensity value at each of a plurality of X and Y positions;
• and
• displaying a 2-D image of the assigned intensity values.
