In Brief Purpose: The purpose of this study was to investigate changes in macular thickness after panretinal photocoagulation (PRP) patients with severe diabetic retinopathy (DR) without edema and compare the visual acuity outcomes. Methods: This prospective cohort included 30 nonproliferative DR or non–high-risk proliferative whose ≥0.8 before PRP. Sixty eyes received biweekly PRP treatment 4 sessions. Macular were measured at 1, 3, 6, 12 months Results: acuities 0.02 ± 0.11 0.04 0.11, 0.07, 0.08 PRP, respectively (P > 0.05 for each). Central increased 1 (223.3 40.6 μm), 3 (216.8 23.5 6 (219.4 33.1 (220.4 17.3 μm) compared that (199.0 20.9 μm; P < Conclusion: Biweekly (1,200–1,600 spots) had no effect on edema, which determined by clinical optical coherence tomography examination, although mild thickening frequently persists.
