Subthreshold Micropulse Photocoagulation for Persistent Macular Edema Secondary to Branch Retinal Vein Occlusion including Best-Corrected Visual Acuity Greater Than 20/40
Figure 2
Persistent macular edema secondary to branch retinal vein occlusion with best-corrected visual acuity (BCVA) > 20/40 treated by SMDLP. (a) Fundus color photograph obtained before SMDLP, showing cystoid macular edema. (b) Fundus color photograph at 3 months after SMDLP. (c) Optical coherence tomography at baseline. (d) Optical coherence tomography at 3 months after treatment. The baseline horizontal scan shows a cystoid area at the fovea that has improved at 3 months. CMT was 525 μm at baseline and 346 μm at 3 months. BCVA (logarithm of the minimum angle of resolution) was 0.046 before SMDLP and 0 at 3 months. (e) Baseline fluorescein angiography revealing diffuse dye leakage in the macular area. SMDLP was applied to the area of diffuse dye leakage.
