FIGURE 3.
(A) Anatomical MRI and (B) choroidal blood flow image of the human retina from one subject. Blood flow was high around the macula and dropped off peripherally. Four ROIs were evaluated: (1) Peripheral temporal region (PTR), (2) Foveal region (FTR), (3) Optic nerve head region (ONHR), and (4) Peripheral nasal region (PNR) (C) Mean BF profile across the retina from c to d, averaged along point a to b (4 mm). The choroidal blood flow was calculated using the peak value. (D) Mean choroidal blood flow from point a (temporal) to b (nasal).
