1. A method for measuring retinal temperature, the method comprising:

  • generating secondary emitted light emanating from retinal tissue;

    detecting the secondary emitted light emanating from the retinal tissue;

    statistically analyzing temporal fluctuation of the detected secondary emitted light using a control unit including electronics configured for determining a statistical scattering characteristic of the secondary emitted light, the statistical scattering characteristic modeling substantially Brownian motion of illuminated particles of the retinal tissue, and to derive a temperature of the retinal tissue from the statistical scattering characteristic modeling substantially Brownian motion of illuminated particles of the retinal tissue.
