Surgical results regarding the correction of macular hole with and without face-down posturing using 25% SF6 gas: a retrospective case series

360-degree pedicled inverted internal limiting membrane flap technique without face-down posturing for large idiopathic macular holes: a retrospective case series

“…In the case series by Bastos et al, no statistical difference was observed in the hole closure rates of the non-FDP and FDP groups, showing comparable anatomical and visual outcomes. In their study, the duration of MH symptoms was an anatomical and visual predictor of visual improvement (MH with duration of <12 months had 100% closure success, whereas those with <24 months had 60% closure, p=0.0012) (1) .…”

“…The beginning and progression of MHs appear to be related to tangential and anteroposterior tractions at the level of the vitreoretinal interface (1,2) . Since Kelly and Wendel's introduction in 1991, pars plana vitrectomy (PPV) and posterior hyaloid removal with or without peeling of the internal limiting membrane (ILM) became the gold standard treatment for full-thickness MHs (FTMHs), with 85%-90% closure (1,3,4) . Globally, studies have emphasized a high and constant rate of anatomical and visual improvements in MHs with a diameter <400 μm; by contrast, only a few studies have reported MHs with a diameter >400 μm and lower closure rates or visual improvement, with closure ranging from 40% to 80% (5)(6)(7)(8)(9)(10) .…”

“…Most macular holes (MHs) are idiopathic and affect patients in their sixth and seventh decades of life (1) . The beginning and progression of MHs appear to be related to tangential and anteroposterior tractions at the level of the vitreoretinal interface (1,2) .…”

“…In 2020, Bastos et al conducted a study in which the nonface-down group who underwent MH surgery with SF6 tamponade had a closure rate not significantly different from that of the FDP group, i.e., 90.4% and 90.3%, respectively, suggesting that postoperative FDP was not strictly required (1) .…”
