Abstract: Purpose: To compare the efficacy of therapy with panretinal photocoagulation (PRP) and intravitreal bevacizumab (IVB) injections versus PRP alone in patients with high-risk proliferative diabetic retinopathy (HR-PDR) with a 6-month follow-up. Methods: Forty-two patients with HR-PDR were prospectively studied in a randomised, masked, controlled trial. Both eyes of each patient were randomised either to the study group (SG) receiving PRP plus IVB injections or the control group (CG) receiving PRP alone. Mean change in visual acuity (VA), optical coherence tomography-measured fovea! thickness (FT) and macular volume (MV) were compared. Results: Intergroup comparisons showed no significant difference in VA while FT exhibited a significant (p < 0.05) difference at 1 month of follow-up and MV was significantly reduced at the 1- and 3-month follow-up. Compared to baseline, VA was significantly worse at all follow-ups in the CG and was stable in the SG. FT increased significantly in the CG from baseline to the 1- and 6-month follow-ups and in the SG, no significant difference was observed. MV was significantly increased in the CG during all follow-up periods. Conclusion: In HR-PDR, using IVB injections as adjuvant treatment to PRP reduces the VA deterioration and results in decreased FT and MV measurements compared to PRP alone.
