Assessment of cutaneous blood flow during healing and scar maturation. (a) Pictures from dynamic OCT in both arms. (b) OCT results at 0.15 mm depth. (c) FLPI-2 pictures from both arms. (d) FLPI-2 results. The treatment and control arms displayed a similar pattern with both devices. A sharp increase in blood flow from baseline is evident in both OCT and FLPI, which does decrease slowly, but returns to baseline by week 16. (e) Pigmentation results using SIAscopy continue to rise by week 16 in both arms, with a decrease at weeks 4 and 12. (f) Colorimetry values rise at week 2 and then plateau, but do not return to baseline values by week 16. There were 40 subjects in the group for the shortest time period (4 weeks), 10 subjects exited at this (and every subsequent) time point, leaving 30 subjects in the week 8 group, 20 subjects in the week 12 group, and finally, 10 subjects in the week 16 group. FLPI, full-field laser perfusion imager; SIAscopy, spectrophotometric intracutaneous analysis.
