Abstract
PURPOSE: The aim of this study was to describe the anatomical outcomes of Brilliant Blue G (BBG)-assisted extensive internal limiting membrane peeling for proliferative vitreoretinopathy (PVR) under three-dimensional (3D) visualization. METHODS: This study constitutes a retrospective case series conducted in a private retina practice, of 14 consecutive patients (14 eyes) with rhegmatogenous retinal detachment complicated by PVR who underwent pars plana vitrectomy between January 2019 and January 2020. The internal limiting membrane (ILM) was selectively stained with BBG, and perspectives were enhanced with a 3D visualization system. We peeled off the ILM beyond the vascular arcades up to the periphery. The main outcome was anatomical success, defined as persistent retinal reattachment after removal of the silicone oil tamponade. RESULTS: Anatomic success was achieved with a single surgery in 11 of 14 (78.6%) eyes, and eventual success was achieved in all eyes. The mean patient follow-up time was 12.3 months (range, 7-16 months). The mean preoperative best-corrected visual acuity (BCVA) was 2.93 ± 0.79 logMAR which improved to 1.75 + 0.91 at the last follow-up. CONCLUSION: Extensive ILM peeling allowed the creation of a cleavage plane underlying the PVR membranes that facilitated its complete removal, thereby achieving anatomically reattached retina and reducing the risk of recurrence of retinal detachment. The long-term effects of this technique need further research.
