1. A method to detect oxidative metabolism of ocular tissue comprising the steps of:

  • bleaching photopigments in said ocular tissue with a bright flash;

    generating a first beam of optical energy of a predetermined reference wavelength;

    generating a second beam of optical energy of a predetermined sample wavelength;

    alternately illuminating said ocular tissue with said first beam and said second beam;

    detecting optical energy reflected by said ocular tissue;

    converting said optical energy to a first electronic signal;

    subtracting a second electronic signal from said first electronic signal to obtain a third electronic signal; and

    processing said third electronic signal to determine said oxidative metabolism.
