Macular hole surgery with internal limiting membrane peeling facilitated by membrane-blue® versus membrane-blue-dual®: A retrospective comparative study

Background. This study aims to compare the outcome of macular hole (MH) surgery with internal limiting membrane (ILM) peeling facilitated by two different vital dyes. Methods. This was a retrospective chart review. The group designated "group-MB" underwent pars plana vitrectomy with ILM peeling facilitated by Membrane-Blue (MB), whereas in "group-MBD," the vital dye used was Membrane-Blue-Dual (MBD). Results. Seventy-four eyes comprised the study population: 53 in group-MB and 21 in group-MBD. There was no difference in the rate of macular hole closure in group-MB or group-MBD: 71.2% closed MHs compared to 66.7%, respectively (p=0.7). Postoperative visual improvement was of a higher magnitude in the MBD group compared to the MB group: -0.34±0.81 logMAR versus 0.01±0.06 logMAR, respectively (p=0.003). Conclusions. In this study, MBD led to better visual results that may be related to better staining characteristics or lesser toxicity compared to MB.
