ABSTRACT:
A method of measuring the oxidative metabolism of ocular tissue. The ocular tissue is alternately illuminated, with light of a sample wavelength corresponding to the absorption peak of cytochrome a,a.sub.3 and light of a reference slightly above or below the sample wavelength. Light reflected by the ocular tissue is detected and an electronic signal corresponding to said light produced. The signal corresponding to the reference wavelength is subtracted from the produced signal. In a preferred embodiment an optical probe with a first probe to deliver light to the ocular tissue and a second probe to deliver reflected light to a detector is provided. The optical probe is placed on the ocular tissue under study.
