APPARATUS FOR PROVIDING RETINAL THERAPY, METHOD FOR TRACKING A CHANGE IN RETINAL CELLS' FUNCTIONAL MODIFICATION

The invention concerns an apparatus for providing retinal therapy of an eye comprising:- a first light source configured to emit a treatment beam with a first wavelength to a selected area of the retina, whereby the retina is external to the apparatus;- a retinal functional tracking means comprising a second light source and a detector, wherein the second light source is arranged to emit light within a spectrum to the selected area of the retina, and wherein the detector is configured to analyse reflected light by the retina at the selected area, wherein the detector is adapted to determine a change in the spectrum of the reflected light; and wherein- the apparatus is configured to adapt a therapeutic dose emitted by the first light source in response to the determination of a change in the spectrum of the reflected light.The invention concerns also a method for detecting a change in retinal cells of an eye stimulated by a treatment beam of a first light.
