System and Method for Determining Volume-Related Parameters of Ocular and Other Biological Tissues

A system for determining a relative thickness at a location of an optic disc, comprising:

• a light source for projecting light towards the optic disc;
• a receiver for receiving light reflected from the optic disc at two spectral wavelengths;
• an image acquisition system in communication with the receiver for forming an image from the reflected light at each wavelength;
• and
• a processor for applying a mathematical model to the image which determines the difference between the absorption of light by the optic disc at a selected image point at each of the two spectral wavelengths to determine the relative thickness of the optic disc at that location.

A method for determining volume-related parameters of a biological tissue, comprising:

• illuminating the biological tissue with light;
• receiving light reflected from the biological tissue at two spectral wavelengths;
• forming an image from the reflected light at each wavelength;
• and
• applying a mathematical model to the image for comparing the absorption of light by the biological tissue at a selected image point at each of the two spectral wavelengths to determine the volume-related parameters of the biological tissue at that location.
