  • Ocular testing method and apparatus
    Patent number: 3963019
    Abstract: A method and apparatus for detecting changes in body chemistry, for example, glycemia, is disclosed in which a beam of light is projected into and through the aqueous humor of the patient's eye. An analyzer positioned to detect the beam on its exit from the patient's eye compares the effect the aqueous humor has on said beam against a norm. An excess or deficiency of glucose present in the aqueous humor produces a corresponding positive or negative variation in the exiting beam and thereby indicates a hyper or hypo glycemia condition in the body chemistry of the patient being tested.
