Abstract
A method and apparatus for determining the presence of substances in human fluids, utilizing variable wavelength beam of light, which is analyzed by spectrographic methods after passage through the vitreous humor of the eye.
Claims16
An apparatus for determining the presence of substances in the vitreous humor of the eye of a subject wherein the absorption of light passing through the vitreous humor of the eye is analyzed comprising in combination:
- (a) means for generating incident light;
- (b) optical means for focusing said incident light through the pupil and the vitreous humor of the eye of a subject and onto the retina of the eye;
- and
- (c) means for measuring the intensity of the incident light that is reflected from the retina back through the vitreous humor and pupil of the eye, and for comparing the intensity of the reflected light with the intensity of the incident light in order to determine the amount of absorption of the incident light passing through the vitreous humor of the eye.
