Detecting Blood Flow Response to Stimulation of the Human Eye

Figure 3

Typical fluorescence-intensity curves recorded from superior temporal segment of retina in a healthy subject with no ocular abnormalities. Both curves begin at approximately the same time. is the time at which recirculation begins and and are mean times of fluorescein from site of injection to site of measurements along artery and vein, respectively. Smooth curves are log-normal distribution functions that optimally fit arterial and venous first passages (reprinted from [36]).
