Sum of the retinal blood flows (SRBF) before and after panretinal photocoagulation (PRP).

<p>SRBF decreased significantly after PRP (<i>P = 0</i>.<i>002</i>, Wilcoxon test). In FA after PRP, though two subjects with NVE and/or NVD (Subjects 1 and 2: yellow lines) had regression of NV, one subject (Subject 3: red line) with NVE did not have regression of NVE. No subject had the formation of new NV. Before PRP, SRBF before starting PRP; After PRP, SRBF four weeks after completing PRP.</p>
