Paper Abstract

Optical coherence tomography angiography (OCTA) provides in-vivo images of microvasculature. In skin it often represents a dynamic perfusion state without depicting the actual extent of the vascular network. Here, we present the capillary refill method for obtaining a more accurate anatomic representation of surface capillary networks in human skin using OCTA. OCTA images were captured at baseline displaying ambient capillary perfusion and after compression and release of the skin representing the network of existing capillaries at full capacity. This method provides mapping of cutaneous capillary networks independent of ambient perfusion comparable to histological analysis of biopsies on identical skin sites.
