Abstract
A device (20) and methods for concurrently taking multiple partially overlapping still or video images (60) of the iridocorneal angle (12) of an eye (1). Device (20) typically comprises a single chassis (100) with an outer surface (101) that approximately matches the curvature of the ocular surface (4). Multiple discrete optical imaging systems (200) are aimed through the cornea (3) and the anterior chamber (17), producing non-coplanar optical paths (21) directed towards corresponding partially overlapping zones (11) of the iridocorneal angle (12). Each system (200) may comprise one or more optical lenses (210, 211), with either fixed or variable position, and a corresponding digital sensor (220) or portion of a larger common shared digital sensor (221).
