    <p>The choriocapillaris can be visualized in all subjects. Some variation between individuals can be noticed. The angiogram in (A) is the same image as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0081499#pone-0081499-g003" target="_blank">Figure 3(A)</a> but in grayscale. Scale bars: 250 µm.</p

    Generating OCT angiography data from OCT intensity data.

    <p>(A) Multiple OCT intensity B-scans are acquired from the same location on the retina and compared with each other pixel-by-pixel to detect motion contrast. The resultant OCT cross-sectional angiogram is segmented with respect to the RPE using one of the corresponding intensity images. (B) By performing the steps in (A) volumetrically and displaying the OCT angiography data in an <i>en face</i> plane below the RPE, the choriocapillaris microvasculature can be visualized. Yellow arrows indicate shadowing artifact from thick retinal vessels.</p
