Abstract:
1. A method of analyzing a retina comprising: applying visible and near-infrared light to the retina; measuring an intensity of light reflected at a plurality of depths for each of a plurality of pixels of the retina within a first band of visible light; measuring an intensity of light reflected at a plurality of depths for each of the plurality of pixels of the retina within a second band of near-infrared light; comparing the intensity of light reflected within the first band and the intensity of light reflected within the second band: defining a retinal nerve fiber layer; segmenting the retina based on the defined retinal nerve fiber layer; summing the intensities of the reflected light of the first band at each depth within the retinal nerve fiber layer for each of the plurality of pixels to calculate a reflectance, R summing the intensities of the reflected light of the second band at each depth within the retinal nerve fiber layer for each of the plurality of pixels to calculate a reflectance, R dividing R
