Figure 1

Representative composite colour maps of the mean blur rate (MBR) as determined by laser speckle flowgraphy (LSFG) in eyes with S-NPDR before, and 1, 4, 8, and 12 weeks after panretinal photocoagulation (PRP) performed by conventional laser and pattern scan laser (PASCAL) treatment at the macula (A). The red colour indicates a high MBR, and the blue colour indicates a low MBR. To measure the choroidal MBR, the center of a square (250 × 250 pixels; 6.31° × 6.31°) was set at the fovea. There was a significant reduction in the choroidal MBR in both the conventional laser and the PASCAL PRP treatment groups (B) after the PRP. The ratio of the choroidal MBR to the baseline was not significantly different between the conventional laser and the PASCAL treatment groups throughout the post-PRP period (C).
