Subthreshold Micropulse Photocoagulation for Persistent Macular Edema Secondary to Branch Retinal Vein Occlusion including Best-Corrected Visual Acuity Greater Than 20/40
Figure 1
Changes in postoperative parameters: 12-month follow-up of all patients after subthreshold micropulse diode laser photocoagulation (SMDLP). (a) Changes in visual acuity (logarithm of the minimum angle of resolution) over time after SMDLP. Visual acuity showed significant improvements at 1 month and 12 months ( and 0.046 resp.). (b) Changes in macular thickness over time after SMDLP. Central macular thickness (CMT) showed a significant decrease at 3 months, and remained stable thereafter (). (c) Changes in macular volume over time after SMDLP. Macular volume showed significant reductions at 1, 6, and 12 months (, 0.002, and 0.049 resp.).
