          Abstract

          Background

          Inverted Internal Limiting Membrane (ILM)-flap technique would seem to lead to higher closure rate and better visual acuity than traditional procedure with ILM peeling for the treatment of large macular hole (LMH). Visual acuity recovery does not reveal many other functional changes related to surgical approach. Our purpose was to evaluate macular function and morphology over a 1-year follow-up after inverted ILM-flap technique for LMH by using microperimetry in order to predict visual prognosis.

          Methods

          This study was a prospective unrandomized single-center study. 23 eyes of 22 patients with idiopathic LMH, with a minimum diameter ranging from 400 to 1000 μm, were included. All patients underwent vitrectomy with inverted ILM-flap technique and gas tamponade. We analyzed macular hole closure rate and functional outcomes including best-corrected visual acuity (BCVA), macular sensitivity (MS) at central 12° and central macular sensitivity (CMS) at central 4°, and fixation behavior as bivariate contour ellipse area (BCEA, degrees 2) at 68%, 95%, and 99% of fixation points measured by microperimeter, over a follow-up of 12 months.

          Results

          The macular hole closure rate was 98%. The BCVA improved from 20/230 (Logmar, 1.06 ± 0.34) to 20/59 (logMar, 0.47 ± 0.45) at last follow-up (p < 0.001). Retinal sensitivity and BCEA significantly improved (MS, p = 0.001; CMS, p < 0.0001; BCEA: 68%, p < 0.01; 95%, p < 0.01; 99%, p = 0.001). Multiple stepwise regression analysis showed the final BCVA was significantly associated with macular hole size (β = 0.002, p = 0.03), preoperative MS (β = − 0.06, p = 0.001) and BCEA at 95% and 99% of fixation points (β = − 0.12, p = 0.01; β = 0.06, p = 0.01).

          Conclusions

          Inverted ILM-flap technique for LMH results in good morphologic and functional outcomes. Macular hole size and microperimetric parameters as preoperative MS and BCEA have a predictive role on post-surgical visual acuity.

          Inverted internal limiting membrane flap technique for large macular holes.

          Large macular holes usually have an increased risk of surgical failure. Up to 44% of large macular holes remain open after 1 surgery. Another 19% to 39% of macular holes are flat-open after surgery. Flat-open macular holes are associated with limited visual acuity. This article presents a modification of the standard macular hole surgery to improve functional and anatomic outcomes in patients with large macular holes. A prospective, randomized clinical trial. Patients with macular holes larger than 400 μm were included. In group 1, 51 eyes of 40 patients underwent standard 3-port pars plana vitrectomy with air. In group 2, 50 eyes of 46 patients underwent a modification of the standard technique, called the inverted internal limiting membrane (ILM) flap technique. In the inverted ILM flap technique, instead of completely removing the ILM after trypan blue staining, a remnant attached to the margins of the macular hole was left in place. This ILM remnant was then inverted upside-down to cover the macular hole. Fluid-air exchange was then performed. Spectral optical coherence tomography and clinical examination were performed before surgery and postoperatively at 1 week and 1, 3, 6, and 12 months. Visual acuity and postoperative macular hole closure. Preoperative mean visual acuity was 0.12 in group 1 and 0.078 in group 2. Macular hole closure was observed in 88% of patients in group 1 and in 98% of patients in group 2. A flat-hole roof with bare retinal pigment epithelium (flat-open) was observed in 19% of patients in group 1 and 2% of patients in group 2. Mean (or median) postoperative visual acuity 12 months after surgery was 0.17 (range, 0.1-0.6) in group 1 and 0.28 (range, 0.02-0.8) in group 2 (P = 0.001). The inverted ILM flap technique prevents the postoperative flat-open appearance of a macular hole and improves both the functional and anatomic outcomes of vitrectomy for macular holes with a diameter greater than 400 μm. Spectral optical coherence tomography after vitrectomy with the inverted ILM flap technique suggests improved foveal anatomy compared with the standard surgery.

              Internal limiting membrane peeling versus no peeling for idiopathic full-thickness macular hole: a pragmatic randomized controlled trial.

              To determine whether internal limiting membrane (ILM) peeling is effective and cost effective compared with no peeling in patients with idiopathic stage 2 or 3 full-thickness maculay hole (FTMH). This was a pragmatic multicenter randomized controlled trial. Eligible participants from nine centers were randomized to ILM peeling or no peeling (1:1 ratio) in addition to phacovitrectomy, including detachment and removal of the posterior hyaloid and gas tamponade. The primary outcome was distance visual acuity (VA) at 6 months after surgery. Secondary outcomes included hole closure, distance VA at other time points, near VA, contrast sensitivity, reading speed, reoperations, complications, resource use, and participant-reported health status, visual function, and costs. Of 141 participants randomized in nine centers, 127 (90%) completed the 6-month follow-up. Nonstatistically significant differences in distance visual acuity at 6 months were found between groups (mean difference, 4.8; 95% confidence interval [CI], -0.3 to 9.8; P = 0.063). There was a significantly higher rate of hole closure in the ILM-peel group (56 [84%] vs. 31 [48%]) at 1 month (odds ratio [OR], 6.23; 95% CI, 2.64-14.73; P < 0.001) with fewer reoperations (8 [12%] vs. 31 [48%]) performed by 6 months (OR, 0.14; 95% CI, 0.05-0.34; P < 0.001). Peeling the ILM is likely to be cost effective. There was no evidence of a difference in distance VA after the ILM peeling and no-ILM peeling techniques. An important benefit in favor of no ILM peeling was ruled out. Given the higher anatomic closure and lower reoperation rates in the ILM-peel group, ILM peeling seems to be the treatment of choice for idiopathic stage 2 to 3 FTMH.
