What did a meta-analysis of studies assessing the safety and efficacy of vitrectomy for diabetic tractional retinal detachment (TRD) find when it comes to the rate of retinal reattachment and final visual acuity? Moderator Katherine Talcott, MD, and panelists Kyle Kovacs, MD, and Rebecca Soares, MD, MPH, outline the top-line findings of this meta-analysis, explore why the study's conclusions brush against conventional understandings of diabetic TRD outcomes following surgery, and ask whether the success bias of published studies undercut the real-world value of meta-analyses.
