Detecting Blood Flow Response to Stimulation of the Human Eye

Figure 7

Optic disc en face maximum decorrelation projection angiograms from a participant with a large response to hyperoxia at baseline (a) and hyperoxia (b). The images represent a 3 × 3 mm area. The optic disc was delineated by the authors and is shown here with inner green ring. The outer green ring is defined as extending 700 µm outward from inner disc. The image after hyperoxia exposure (b) shows a reported 17% decrease in flow index and a 4% decrease in vessel density (reprinted from [134]).
