Abstract:
1. A method of analyzing optical coherence tomography (OCT) image data of an eye, said eye being examined by an OCT system, said OCT system including a light source for 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: a. scanning the beam of light over a region of the eye via the sample arm; b. combining the light from the sample and reference arms; c. measuring the combined light; d. generating three dimensional volume image data corresponding to structures within the eye from the combined light; e. identifying two anatomical surfaces within the image data, wherein each anatomical surface is described by a set of physical coordinates; f. determining a mathematically defined, non-anatomical additional surface located between the two identified anatomical surfaces, wherein the coordinates of the additional mathematically defined surface are represented as a mathematical combination of the coordinates of the two identified anatomical surfaces; and g. storing the coordinates of the additional mathematically defined surface for further analysis or displaying an image of the eye using the identified additional mathematically defined surface.
