Abstract

A method and apparatus of early-stage detection of glaucoma and other optic nerve or retinal diseases employs dynamic images that are processed differently by Y-like cells and X-like cells to provide a sensitive detection of early Y-like cell impairment which provides early indications of glaucoma isolated from non-specific information from X-like cells.
