Fig. 1From: Repeatability of ocular surface vessel density measurements with optical coherence tomography angiographyRepresentative OCTA-based measurement of ocular surface vessel density on a 3 × 3 mm2 scan. The left upper panel shows the angiography images of the scanning area in normal eyes. The red dots on the lower panel mark the tomographic vessel signals. The middle two panels represent an eye with pinguecula, and the right two panels represent an eye with pterygiumBack to article page
