Less Expansion of Short-Pulse Laser Scars in Panretinal Photocoagulation for Diabetic Retinopathy

Figure 1

Representative images of fundus autofluorescence (FAF) in the conventional laser group. The images were taken 1 month after laser treatment (a, b) and 12 months after treatment (c, d). Twenty laser scars near the vascular arcade were measured using the digital image analysis software ImageJ on each visit. Higher magnification of the area surrounded by white-dashed line was shown in (b) and (d). White line indicated the outline of FAF laser scars for measurement (b, d). High magnification images show the changes of laser scars from hyperautofluorescent at 1 months (b) to hypoautofluorescent at 12 months after laser treatment (d).
