ABSTRACT:
A non-invasive eye oximeter which monitors the arteriovenous oxygen difference. The optic disc region of the ocular fundus is illuminated with three or more wavelengths of light focused in approximately the same area. One of the light sources serves as a tracking beam which, through reflectance spectrophotometry, is used to determine when the tracking light beam is focused upon the optic disc. The scanning light beams are primarily focused within the boundary of the tracking beam. The intensity of light reflected from retinal venules and arterioles is detected, and the arteriovenous oxygen difference is determined.
