Change of mean blur rate (MBR), skew, blowout time (BOT) after half-dose photodynamic therapy (PDT). (a) The MBR of the PDT irradiation area was significantly decreased from baseline after half-dose PDT. (b) The MBR in the pachyvessel area (PV area), the area without pachyvessels or filling delay (NPV area), and the filling delay area (FD area) significantly decreased from baseline. (c) The changes in the MBR from baseline were not significantly different among the PV, NPV, and FD areas at 1, 3, and 6 months. (d) The skew in the whole area. (e) The skew in the PV, NPV, and FD areas. (f) The BOT in the whole area. (g) The BOT in the PV, NPV, and FD areas. AU: arbitrary units. ***P < 0.001.
