Abstract
Embodiments of the present invention provide a computer-implemented method of determining a scattering spectrum of an eye. The method comprises receiving data from a detector indicative of a reflected wave of radiation reflected from the retina, wherein the reflected wave of radiation is formed by an incident wave of masked radiation directed towards a retina of the eye, such that at least one region masked from the incident wave is present on the retina, determining a first back scattering spectrum indicative of light scattered from an optical media of the eye in dependence on a portion of the reflected wave of radiation corresponding to the at least one masked region, determining a second back scattering spectrum indicative of light scattered from a neural retina of the eye in dependence on retinal structure information representative of neural retinal structure, and determining the scattering spectrum of the eye in dependence on the first back scattering spectrum and the second back scattering spectrum.
