<p>A method for determining a blood oxygenation associated with a brain of a subject, the method includes scanning a retina of the subject to identify at least one retinal blood vessel using at least a first optical energy source. In response to the identifying, identified retinal blood vessel is selectively flashed using at least a second optical energy source. At least one reflectance is detected from the flashed retinal blood vessel, and a ratio being indicative of the oxygenation using the detected at least one reflectance is determined.</p> |
