Real-World Outcomes of Different Types of Treatment for Diabetic Macular Edema Before and After Approval of Anti-Vascular Endothelium Growth Factor Agents.

: The object of this study was to determine the outcomes of treatments other than anti-vascular endothelial growth factor (VEGF) therapy for diabetic macular edema (DME) before and after the approval of anti-VEGF therapy in Japan. : This was a retrospective study registered in the database of the Survey of Treatment for DME (STREAT-DME). A total of 1683 patients treated from 2010 to 2017 were included. The patients were divided into two groups: (1) a pre-group, treated before the approval of anti-VEGF agents (2010-2013, = 771), and (2) a post-group (2014-2017, = 912). Each group was further categorized based on best-corrected visual acuity (BCVA): (i) improved from poor (>0.3 logMAR units) to good (≤0.3 logMAR units) or (ii) decreased from good to poor. : In the pre-group, 18.5% of patients improved from poor to good BCVA out of the total patient population ( < 0.0001), along with 17.3% out of those administered anti-VEGF therapy ( = 0.139), 20.5% of those administered a sub-tenon injection of triamcinolone acetonide (STTA, = 0.02), 17.7% ( = 0.20) of those administered photocoagulation, and 14.2% of those who underwent pars plana vitrectomy (PPV, = 0.0001). In the post-group, 21.8% had improved BCVA out of the total patient population ( < 0.0001), along with 27.2% of those undergoing anti-VEGF therapy ( < 0.0001), 16.7% of those administered STTA ( < 0.0001), and 27.2% of those who underwent PPV ( < 0.0001). : STTA and PPV are effective to a certain extent, even after the approval of anti-VEGF agents.
