Abstract:
A method of detecting and classifying retinal pathologies, including glaucoma and diabetic macular edema, said method comprising:(a) illuminating a sequence of predetermined locations on a retina; (b) receiving light returning from said predetermined locations; (c) generating a series of primary graphs each representing the intensity of the returning light as a function of the retinal depth at one of said predetermined locations; (d) separating each of said primary graphs into a first component curve corresponding to the light returning substantially from the Nerve Fiber Layer of the retina and a second component curve corresponding to the light returning substantially from the Retinal Pigment Epithelium of the retina; (e) analyzing at least one of said component curves to obtain data including, but not limited to, data corresponding to the front slope and/or back slope and/or area of said at least one of said component curves; and (f) comparing the data to analogous pre-specified data.
