Multispectral and hyperspectral ocular surface evaluator

Abstract

A multispectral or hyperspectral ocular surface evaluating device is disclosed, comprising an illumination projector, which comprises a broadband illumination source panel and a polarizing structure to illuminate an ocular surface and adjacent structures of an eye and project a pattern on the ocular surface; an imaging system to form images; a detection system to record the images with a plurality of spectral channels in visible and near infrared spectra; and a computer to display and analyze the images. Also disclosed is a method of evaluating ocular surface health using a multispectral or hyperspectral ocular surface evaluating device, which comprises illuminating an ocular surface and adjacent structures of an eye with polarized light from an illumination projector; forming images with the imaging system; recording images formed on the detection system; digitally processing the recorded images; and analyzing the recorded images to evaluate ocular surface health with the computer.
