Abstract Purpose: To evaluate the efficacy of the modified superior inverted internal limiting (ILM) membrane flap technique in retinal reattachment, macular hole closure and external retinal layers restoration in macular hole associated retinal detachment compared to ILM peeling. Methods: Retrospective case series of 10 patients that required pars plana vitrectomy for retinal detachment with macular hole followed for more than 12 months. Data from medical records were retrospectively collected and patients were divided into the superior inverted flap (5 patients) and ILM peeling group (5 patients). We compared best corrected visual acuity (BCVA) before and after surgery, retinal attachment, macular hole closure rate and external retinal layer restoration between groups. Results: There were significant improvements in BCVA in both groups before and after surgery, with no differences between the two groups at 12 months after surgery (p = 0.9). The macular hole closed in 100% of cases in the inverted flap group and 80% of the ILM peeling group with no significant differences between groups. The retina was reattached in 100% of cases in both groups. Only 2 patients in the inverted flap group (40%) had external retinal layer restoration and none in ILM peeling group (p=0,62). Conclusions: ILM peeling and superior inverted flap techniques are useful for treating retinal detachment with macular hole in myopic eyes.

PurposeThe aim of this study was to determine the effect of the inverted internal limiting membrane (ILM) flap technique on the macular hole (MH) closure and foveal microstructure recovery of patients with highly myopic MH.MethodsPars plana vitrectomy and gas tamponade with the inverted ILM flap technique (19 eyes) or with the ILM peeling technique (21 eyes) were performed in patients with highly myopic MH with or without retinal detachment. The rate of MH closure and retinal reattachment, the reconstructive anatomical change of the foveal microstructure and the best-corrected visual acuities (BCVA) of the two groups were compared.ResultsThe anatomic closure rate was statistically significantly higher in the inverted group (100%) than in the peeling group (66.7%; p=0.009). All eyes with MH retinal detachment had successful retinal reattachment in these two groups. However, the rate of the external limiting membrane (ELM) and ellipsoid zone (EZ) (p=0.020), as well as gliosis (p=0.049) in macular area, detected by OCT, was significantly greater in the inverted group than in the peeling group. The postoperative BCVA was significantly better in the eyes with ELM, EZ (p=0.031) and gliosis (p=0.008), but without hyperreflective foci (p=0.001).ConclusionsThese findings demonstrate that the inverted ILM flap technique has better efficacy than the ILM peeling technique for patients with myopic MH in closure rate, foveal microstructure and postoperative BCVA.

Background. The aim of this meta-analysis was to compare morphological and functional outcomes between vitrectomy with the inverted internal limiting membrane (ILM) flap technique and vitrectomy with internal limiting membrane peeling in highly myopic eyes with macular hole- (MH-) induced retinal detachment (MHRD). Methods. The PubMed, Web of Science, Embase, and Cochrane Library databases were comprehensively searched from inception to November 10, 2019, for published studies comparing the two techniques for the treatment of MHRD. The outcomes in the collected articles included the postoperative MH closure rate, retinal reattachment rate, and best-corrected visual acuity (BCVA). Review Manager (version 5.3) was used for analyses. Results. In total, seven retrospective studies comparing the inverted ILM flap technique with ILM peeling for the treatment of MHRD were included. The MH closure rate was significantly higher in the inverted ILM flap group than in the ILM peeling group at 6 and 12 months after initial surgery (OR = 15.39; 95% CI: 6.68 to 35.43;P<0.00001 and OR = 12.58, 95% CI: 3.51 to 45.08; P=0.0001), while the retinal reattachment rate was similar in both groups at 6 months after initial surgery (OR = 2.40; 95% CI: 0.89 to 6.50; P=0.08). Besides, the postoperative BCVA was significantly better in the inverted ILM flap group than in the ILM peeling group at 12 months after initial surgery (MD = −0.35; 95% CI: −0.52 to −0.18; P<0.0001). Conclusions. Thus, the MH closure rate and postoperative BCVA may be better with the inverted ILM flap technique than with ILM peeling for myopic MHRD, while the postoperative retinal reattachment rate appears to be similar with both techniques. Therefore, in the future, vitrectomy with the inverted ILM flap technique should be preferred over standard ILM peeling technique for the treatment of MHRD in highly myopic eyes.

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, degrees2) 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.

Purpose: Classical or temporal internal limiting membrane (ILM) flap transposition with air or gas tamponade are current trends with the potential to improve surgical results, especially in cases with large macular holes. Methods: A prospective case series included patients with idiopathic macular holes or persistent macular holes after 23-G pars plana vitrectomy (PPV) and ILM peeling with gas tamponade. In all patients, 23-G PPV and ILM peeling with ILM flap transposition with gas tamponade and postoperative face-down position was performed. Results: In 7 of 9 eyes, temporal ILM flap transposition combined with pedicle ILM flap could be successfully performed and macular holes were closed in all eyes after surgery. The remaining 2 eyes were converted to pedicle ILM flap transposition with macular hole closure after surgery. Three eyes were scheduled as pedicle ILM flap transposition due to previous ILM peeling. In 2 of these eyes, the macular hole could be closed with pedicle ILM flap transposition. In 3 eyes, free ILM flap transposition was performed and in 2 of these eyes macular hole could be closed after surgery, whereas in 1 eye a second surgery, performed as pedicle ILM flap transposition, was performed and led to successful macular hole closure. Conclusions: Use of ILM flaps in surgical repair of macular hole surgery is a new option of treatment with excellent results independent of the diameter of macular holes. For patients with persistent macular holes, pedicle ILM flap transposition or free ILM flap transposition are surgical options.

Introduction. The few published studies that exist on the surgical outcomes of full-thickness macular hole (FTMH) repair in Macular Telangiectasia (MacTel) Type 2 report poor rates of hole closure of around 30%. This study is the largest case series of patients with FTMH in MacTel Type 2 and describes an 80% hole closure rate. Purpose/Aim. To describe the outcomes of four patients who underwent surgery for FTMH associated with MacTel Type 2. Methods. A retrospective review of clinical, surgical, and imaging data of five eyes in four patients with MacTel Type 2 FTMH who underwent pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and 30% SF6 or 15% C3F8 gas tamponade within 3-9 months of initial vision decline. Results. Visual acuity (VA) at the time of surgery ranged from 20/50 to 20/200. Successful hole closure was achieved in four out of five eyes, and final VA ranged from 20/20 to 20/40 at follow-up visits greater than 20 months postoperatively. The single eye that did not achieve hole closure had a final VA of 20/60. Conclusion. Our case series describes higher hole closure rates and better final VA than previously published reports for macular hole surgery in patients with MacTel Type 2 FTMH.

Purpose: To investigate the surgical outcomes of the inverted internal limiting membrane (ILM) flap technique for macular hole retinal detachment (MHRD) in high myopia.Methods: This was a retrospective interventional study on 45 highly myopic eyes with MHRD after ILM peeling (n = 24, peeling group) or the inverted ILM flap technique (n = 21, inverted group). The inverted group was consisted of autologous blood (AB) subgroup (n = 10) and perfluorocarbon liquid (PFCL) subgroup (n = 11). MH closure, best-corrected visual acuity (BCVA), foveal microstructures, and excessive gliosis were analyzed during a follow-up of over 12 months.Results: The inverted group achieved a higher MH closure rate (95.24%) than the peeling group (41.67%; p &lt; 0.001). No significant difference was found in postoperative BCVA between the two groups (p = 0.98) or between the closed MH with or without excessive gliosis (p = 0.60). Excessive gliosis was identified in 9 eyes in the inverted group, and there was no difference in the incidence of excessive gliosis between the AB subgroup (4 in 10 eyes, 40%) and the PFCL subgroup (5 in 11 eyes, 45.45%) (p &gt; 0.999).Conclusion: The inverted ILM flap technique was effective in MH closure but had no advantage in postoperative BCVA and microstructural restoration. Excessive gliosis was only detected in the inverted group but did not affect the postoperative BCVA. Additionally, the incidence of excessive gliosis was not affected by adjuvants.

Background Macular holes are vitreoretinal interface disorders due to anatomical defects in the fovea causing poor central vision. The aim of this study was to compare the results of four different variants of inverted flap (IF) technique, for the closure of macular holes larger than 400µm. Methods This is a prospective comparative case series. Thirty-six eyes with large macular hole were enrolled: group 1: inserted internal limiting membrane (ILM); group 2: classic IF ILM; group 3: IF without manipulation (Free Flap technique), group 4: temporal IF technique. Best-corrected visual acuity (BCVA), anatomical closure rate, and ellipsoid zone (EZ) and external limiting membrane (ELM) defects were evaluated preoperatively, at 1 month and 3 months after surgery. Odds ratio (OR) and its 95% confidence interval (CI) were used to compare the anatomical and functional results of classic inverted flap ILM peeling (group 2) and modified inverted flap ILM peeling (Group 1,3 and 4). Results Mean BCVA improved in all four groups 3 months after surgery. The improvement was significant in group 2,3, and 4 (P=0.001). The rate of successful hole closure ranged from 87.5% to 100% in different groups (P=0.661). The integrity of EZ was achieved in 65.6% and the restoration of the inner layers of the retina in 71.5%. Conclusion Inverted flap ILM technique is efficient for the treatment of large full thickness macular hole (FTMH). Different modified inverted flap techniques have been described on the last decade. Through our study, we demonstrated that the inserted flap, may alter outer retinal layer and compromise final functional results despite final closure of the macular hole. The classic IF technique, the temporal and the free flap techniques have finally comparable good functional and anatomical results. Key words inverted flap technique, macular hole, surgery, outcomes

Abstract Purpose: To compare the anatomical, morphological, and functional outcomes of the conventional internal limiting membrane (ILM) peeling versus temporal inverted internal limiting membrane flap technique for large full-thickness macular holes (FTMHs). Subjects and Methods: Forty-six eyes of 44 patients with a minimum base diameter > 600 µm were included in this retrospective interventional study. The patients were divided into Group 1 (conventional ILM peeling) and Group 2 (temporal inverted ILM flap). The hole closure rate, best-corrected visual acuity (BCVA), ellipsoid zone (EZ), and external limiting membrane (ELM) defects were analyzed at baseline and 6 months after surgery.Results: Hole closure was achieved in 17/25 (68%) cases of Group 1 and 20/21 (95.2%) cases of Group 2. The hole closure rate was significantly higher in the temporal inverted ILM flap group (p = 0.022). The mean BCVA (logMAR) changed from 1.12 ± 0.43 to 0.72 ± 0.31 in Group 1 and from 1.07 ± 0.34 to 0.51 ± 0.26 in Group 2 at six months (p < 0.001 in both cases). U-shaped closure was observed in 3 (12%) eyes in Group 1 and 15 (71.4%) eyes in Group 2 (p < 0.001). The total restoration rates of ELM and EZ were significantly higher in the temporal inverted ILM flap group (p = 0.009, p = 0.001, respectively).Conclusion: The temporal inverted ILM flap technique is more effective than conventional ILM peeling for larger than 600 µm macular holes and improves anatomical, morphological, and functional outcomes.

Background: Vitrectomy with internal limiting membrane (ILM) peeling is an effective surgical procedure for the treatment of macular holes (MHs). However, there is a possibility of poor postoperative anatomical closure with conventional ILM peeling for MHs larger than 400 μm. Therefore, a novel inverted ILM flap technique was developed for such cases. Objectives: This meta-analysis study was performed to evaluate and compare the anatomical and visual outcomes of the inverted ILM flap technique and ILM peeling in large MHs. Methods: The Cochrane Library, PubMed, and Embase databases were searched to identify randomized controlled trials (RCTs). The trial eligibility and risk of bias were assessed according to Cochrane review methods. The primary outcome measures included MH closure rate and postoperative visual acuity (VA). Subgroup analysis of postoperative VA based on follow-up time was also conducted. Pooled odds ratios (ORs), weighted mean difference (WMD), and 95% confidence intervals (CIs) were calculated. Statistical analysis was performed using RevMan 5.3 software. Results: Five RCTs with a total of 155 eyes in the inverted ILM flap group and 161 eyes in the ILM peeling group were included in this meta-analysis. Statistical meta-analysis revealed that the overall MH closure rate in the inverted ILM flap group was significantly higher than that in the ILM peeling group (OR, 3.10; 95% CI, 1.25 to 7.66; P = 0.01). The postoperative VA was significantly better in the inverted ILM flap group than ILM peeling group (WMD, -0.14; 95% CI, -0.21 to -0.07; P = 0.0002). The subgroup meta-analysis indicated that the postoperative VA was significantly better in the inverted ILM flap group than ILM peeling group (WMD, -0.17; 95% CI, -0.26 to -0.08; P = 0.0004) at the 3-month follow-up. However, no significant difference was observed between the two groups at the 6-month follow-up (WMD, -0.09; 95% CI, -0.20 to 0.02; P = 0.10). Conclusions: Vitrectomy with inverted ILM flap technique showed a higher anatomical closure rate as well as visual gain—although only in the short-term as no difference in visual recovery was found at the 6-month follow-up—than did ILM peeling in large MHs. The inverted ILM flap technique should be considered as a preferred and routine procedure for the treatment of patients with MHs larger than 400 µm.
