Direct Photocoagulation Guided by Merged Retinal Images for the Treatment of Focal Diabetic Macular Edema

Figure 2

Steps for marking the location of microaneurysms (MAs) in the merged image-guided photocoagulation (MIG-PC) method. (a) Ocular fundus photograph shows focal diabetic macular edema accompanied by a hard exudate ring. (b) OCT map is overlaid on the fundus photograph. (c) Image of fluorescein angiography (FA) is merged with the fundus photograph and OCT map. (d) High-magnification image corresponding to the rectangular area is indicated with white-dashed line in Figures 2(a) and 2(c). (e) MAs are marked on the ocular fundus as yellow circles.
