Abstract
INTRODUCTION We compared postoperative metamorphopsia and optical coherence tomography (OCT) findings between eyes that underwent internal limiting membrane (ILM) peeling and the inverted flap (IF) technique for macular hole (MH). METHODS This retrospective analysis included 64 eyes of 64 patients with idiopathic MH whose MH was closed after initial surgery. Thirty-nine patients were treated with pars plana vitrectomy (PPV) with ILM peeling, and 25 patients were treated with PPV with the IF technique. Best corrected visual acuity (BCVA), severity of metamorphopsia, and OCT images were collected before and 3, 6, and 12 months postoperatively. Based on the OCT images, the status of the external limiting membrane (ELM) and ellipsoid zone and the presence of hyperreflective plugs were assessed. RESULTS At baseline and 3, 6, and 12 months postoperatively, BCVA and severity of metamorphopsia were not significantly different between groups. The status of the ELM was significantly worse in the IF group than in the ILM peeling group at 3 and 6 months postoperatively. Significantly more hyperreflective plugs were observed in the IF group than in the ILM peeling group at 3 and 6 months postoperatively. Stepwise multiregression analysis revealed that hyperreflective plugs were significantly associated with the severity of metamorphopsia at 12 months postoperatively. DISCUSSION/CONCLUSION The alterations on the OCT were fewer in the ILM peeling group than in the IF group, while no significant differences were observed in postoperative severity of metamorphopsia between groups. Metamorphopsia was worse in eyes with hyperreflective plugs.

[PMID: 37083504 DOI: 10.1080/08820538.2023.2204925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 04/11/2023] [Accepted: 04/17/2023] [Indexed: 04/22/2023]
Abstract
PURPOSE We aimed to describe single layered free ILM graft technique (FIGT) and present results of this technique in the primary surgery of large macular holes (MHs). METHODS In this retrospective study, we identified MHs with a minimum hole diameter >400 μm that underwent FIGT by a single surgeon. Nineteen eyes were found to have an associated epiretinal membrane (ERM) and four eyes demonstrated a patchy ILM staining intraoperatively. A single layered FIGT was performed first by peeling the ILM around the hole and then creating a free ILM flap and transplanting it to cover the hole. All cases were evaluated for anatomical closure and visual improvement. RESULTS Twenty-three eyes of 22 patients (mean age 68.7 ± 7.4 years) were included in the study. The mean follow-up was 9.6 ± 4.9 months. Flap closure was observed in two eyes (8.6%) at week 1, while all eyes (100%) showed a complete closure at month 1. Mean preoperative visual acuity of 1.42 ± 0.66 LogMAR increased to 1.11 ± 0.51, 0.99 ± 0.34, 0.92 ± 0.38, 0.74 ± 0.37, 0.52 ± 0.28, 0.64 ± 0.39 respectively at week 1, month 1, month 3, month 6, year 1 and final follow-up postoperatively (p < .05 for all). In none of the eyes ERM recurred, nor flap contraction developed. CONCLUSION The study showed encouraging results using free ILM graft in the primary surgery of large MHs. This technique might be considered in large MHs that are associated with ERM or demonstrate patchy ILM staining. Further studies are needed to prove the effectiveness also in the long-term.

Abstract
PURPOSES This meta-analysis aimed to compare and evaluate the morphological and functional outcomes between the inverted internal limiting membrane (ILM) flap and ILM insertion techniques in the treatment of large macular holes (MHs). METHODS The PubMed, Embase, and Cochrane Library databases were searched for relevant studies comparing the two techniques for the treatment of large MHs. The primary outcome measures included the MH closure rate, preoperative and postoperative best-corrected visual acuity (BCVA), MH closure patterns, and external limiting membrane (ELM) and ellipsoid zone (EZ) recovery. Statistical analyses were performed using RevMan 5.3 software. RESULTS Two randomized controlled trials and four retrospective studies were included in this meta-analysis. The MH closure rate did not significantly differ between the two groups (P = .93). Postoperative BCVA was not significantly different between the two groups at 3 months (P = .20) or 6 months (P = .51). ELM and EZ recovery were also similar between the two groups. However, the results for postoperative BCVA and outer retinal structure recovery tended to favor the ILM flap group based on the forest plot. There was no significant difference between the two groups for the U-shape (P = .26), V-shape (P = .65), and W-shape closure types (P = .38). CONCLUSIONS Our meta-analysis provides evidence that the MH closure rate and visual function outcomes are similar between the ILM flap and ILM insertion techniques in large MHs. However, based on the forest plot, postoperative BCVA and outer retinal layer reconstruction tended to favor the ILM flap technique. Further studies with larger sample sizes are required to confirm the superiority of the ILM flap to the ILM insertion technique.

BMC Ophthalmol 2023; 23:274. [PMID: 37316769 DOI: 10.1186/s12886-023-03006-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2021] [Accepted: 05/30/2023] [Indexed: 06/16/2023] Open
Abstract
BACKGROUND The internal limiting membrane (ILM) insertion technique was widely used to treat large macular hole (MH) for the high closure rate. However, the prognosis of closed MH after ILM insertion compared to ILM peeling remains controversial. This study aimed to compare foveal microstructure and microperimeter in large idiopathic MH surgically closed by ILM peeling and ILM insertion. METHODS This retrospective, non-randomized, comparative study included patients with idiopathic MH (minimum diameter ≥ 650 μm) who underwent primary pars plana vitrectomy (PPV) with ILM peeling or ILM insertion. The initial closure rate was recorded. Patients with initially closed MHs were divided into two groups according to the surgery methods. The best-corrected visual acuity (BCVA), optical coherence tomography (OCT) and microperimeter-3 (MP-3) outcomes of two groups were compared at baseline, 1 and 4 months postoperatively. RESULTS For idiopathic MH (minimum diameter ≥ 650 μm), ILM insertion had a significantly higher initial closure rate than ILM peeling (71.19% vs. 97.62%, P = 0.001). Among 39 patients with initially closed MHs who were on regular follow-up, twenty-one were assigned to the ILM peeling group and 18 to the ILM insertion group. Postoperative BCVA improved significantly in both groups. The final BCVA (logMAR) (0.40 vs. 0.88, P < 0.001), macular hole sensitivity (19.66 dB vs. 14.14 dB, P < 0.001), peripheral sensitivity of macular hole (24.63 dB vs. 21.95 dB, P = 0.005), and fixation stability (FS) within 2 degrees (82.42% vs. 70.57%, P = 0.031) were significantly better and external limiting membrane (ELM) defect (330.14 μm vs. 788.28 μm, P < 0.001) and ellipsoid zone (EZ) defect (746.95 μm vs. 1105.11 μm, P = 0.010) were significantly smaller in the ILM peeling group than in the ILM insertion group. CONCLUSION For initially closed MHs (minimum diameter ≥ 650 μm), both ILM peeling and ILM insertion significantly improved the microstructure and microperimeter in the fovea. However, ILM insertion was less efficient at microstructural and functional recovery after surgery.

Abstract
PURPOSE To compare the anatomical and visual outcomes of extra-large idiopathic macular holes treated with internal limiting membrane peeling and two inverted internal limiting membrane flap techniques, namely insertion and cover technique. METHODS Patients with idiopathic macular holes (minimum linear diameter ≥ 650 µm) were divided into peeling group, insertion group, and cover group. The initial closure rate, final length of external limiting membrane and ellipsoid zone recovery, and best-corrected visual acuity were evaluated. RESULTS A total of 124 eyes were included, and the average follow-up was 7.2 months. All the baseline characteristics were comparable among the three groups. Initial closure rate of the peeling group, the insertion group, and the cover group was 65.0% (26/40), 97.6% (41/42), and 90.5% (38/42), respectively (P < 0.001). In closed idiopathic macular holes, the peeling group and the cover group exhibited significantly longer length of external limiting membrane recovery than the insertion group (P < 0.001), and the peeling group exhibited significantly longer length of ellipsoid zone recovery than the other two groups (P = 0.021). The peeling group and the cover group exhibited significantly better best-corrected visual acuity improvement than the insertion group (P = 0.009). CONCLUSION For extra-large idiopathic macular holes, cover technique surpasses internal limiting membrane peeling technique in closure rate and outperforms insertion technique in anatomical and functional recovery, whereas insertion technique may adversely affect the recovery of foveal microstructure and best-corrected visual acuity.

Comparative Study of Conventional Inverted ILM Flap Covering and ILM Flap Filling Technique in Idiopathic Macular Hole Treatment: A Meta-Analysis and Systematic Review. J Ophthalmol 2022; 2022:4922616. [PMID: 36237559 PMCID: PMC9553370 DOI: 10.1155/2022/4922616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 08/25/2022] [Indexed: 11/17/2022] Open
Abstract
Objective This meta-analysis was performed to evaluate the anatomical efficacy and functional improvement of the conventional inverted internal limiting membrane (ILM), flap covering technique, and ILM flap filling technique for patients with idiopathic macular hole (MH). Methods Literature from Pubmed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science were comprehensively retrieved. The primary outcomes included the MH closure rate and postoperative best-corrected visual acuity (BCVA). The secondary outcomes were the proportion of external limiting membrane (ELM) and ellipsoid zone (EZ) defect recovery. Pooled odds ratios (ORs), weighted mean differences (WMDs), and 95% confidence intervals (CIs) were calculated using STATA 17.0 software. Results 7 studies that contained 139 eyes in the inverted ILM flap covering group and 121 eyes in the ILM flap filling group were selected. Pooled data suggested that the surgical treatment resulted in an overall MH closure rate of up to 97.12% (135/139 eyes) in the inverted ILM flap covering group and 99.17% (120/121 eyes) in the filling group, with no significant difference between the 2 groups (OR = 1.98, 95% CI: 0.55 to 7.09, and P=0.29). Similarly, the 2 techniques demonstrated equal effectiveness on the anatomical closure in MH with the average diameter smaller than 650 μm (OR = 2.17, 95% CI: 0.48 to 9.77, and P=0.31) and larger than 650 μm (OR = 1.58, 95% CI: 0.14 to 17.37, and P=0.71). However, compared with the filling technique, the inverted ILM flap covering technique was superior in postoperative BCVA (WMD = 0.11, 95% CI: 0.04 to 0.18, and P=0.0017) and presented a significantly higher proportion of reconstitution of ELM (OR = 0.02, 95% CI: 0.00 to 0.08, and P < 0.0001) and EZ (OR = 0.11, 95% CI: 0.04 to 0.32, and P=0.0001). Conclusion The inverted ILM flap covering technique was associated with the superior reconstitution of outer layers of the retina, including ELM and EZ, and more improvement in postoperative BCVA than the ILM flap filling technique.

Abstract
To investigate the surgical outcomes of pars plana vitrectomy (PPV) combined with inverted multi-layer internal limiting membrane (ILM) flap for the treatment of macular hole retinal detachment in high myopia. We retrospectively analysed the medical records of macular hole retinal detachment (MHRD) patients with high myopia. The patients were divided into two groups with different surgical procedure: inverted multi-layer ILM flap group (group 1, 27 eyes) and the ILM peeling group (group 2, 29 eyes). Retinal reattachment rate, macular hole closure rate at last follow-up and BCVA at 6 months post-operation were compared between the two groups. After primary PPV and silicone oil removal, the retinal reattachment rate was 96.3% in group 1 and 93.1% in group 2 respectively at last follow-up, showing no statistically significant difference (odds ratio = 0.525, P = 1.000). All eyes in group 1 had type I macular closure (100%, 27/27), while only 7 eyes (24.1%, 7/29) in group 2 have type I macular hole closure. The difference was statistically significant (odds ratio = 0, P < 0.05). The mean logMAR BCVA both improved significantly at 6 months post-operation compared with pre-operation (t = 4.181, P < 0.001; t = 3.217, P < 0.001), however the difference of post-operation BCVA between the two groups was not statistically significant (t = 0.906, P > 0.05). PPV combined with inverted multi-layer ILM flap could achieve better anatomical outcomes than ILM peeling technique with no significant advantage in functional outcomes.

Abstract
Inverted internal limiting membrane (ILM) flap technique was developed to achieve macular hole (MH) closure in large MH and refractory cases. In this study, we evaluate the effect of the technique for small-medium size MH. We recruited patients who underwent vitrectomy for small-medium size (< 400 μm) MH with either inverted ILM flap technique (flap group) or with conventional ILM peeling (peeling group). Using propensity score, 21 eyes of 21 patients in the peeling group were matched against 21 eyes of 21 patients in the flap group. We compared MH closure rate, postoperative visual acuity, and recovery of the external limiting membrane (ELM) and ellipsoid zone (EZ). The MH closure rate was not different between the two groups (flap vs peeling: 90% vs 100%, P = 0.49). Whereas there was no significant difference in visual acuity improvement between the two groups, the flap group showed more disruption of the ELM 3 months after surgery and of the EZ at 3 and 6 months after surgery (P = 0.02, P = 0.03, and P = 0.04, respectively). The result suggested that inverted ILM flap technique does not have additional benefits for small-medium size MHs and may delay recovery of retinal integrity.

Abstract
BACKGROUND AND OBJECTIVE This meta-analysis reviews available surgical techniques for the repair of macular holes (MHs) >650 μm. MATERIAL AND METHODS PubMed search criteria were used to identify 17 studies outlining surgical techniques for the repair of MHs >650 μm. Thirteen of the studies identified individual cases and were further analyzed based on MH classification. Success was defined as functional improvement and anatomic closure of the hole. RESULTS Two hundred and six MHs were included in this study. There were clinically significant differences between the repair of primary and refractory MHs. Autologous retinal transplant resulted in a visual acuity improvement of -0.48 ± 0.36 log-MAR, whereas an inverted internal limiting membrane (ILM) flap and pedicle ILM flap resulted in visual acuity improvements of -0.15 ± 0.17 and -0.14 ± 0.91 logMAR, respectively. CONCLUSION An inverted or pedicle ILM flap appears more effective for primary MHs, whereas refractory MHs benefit from a free flap. [Ophthalmic Surg Lasers Imaging Retina. 2022;53:52-61.].

Abstract
Purpose: To report a simple modification of internal limiting membrane (ILM) peeling tailored to the shape of the macular hole to improve the closure rates. Methods: This is a single-center interventional case series. conducted between 2016 and 2020. The minimum follow-up was 4 months. All surgeries were performed by one surgeon. Twenty consecutive patients (21 eyes) with large idiopathic macular holes (horizontal diameter: ≥600 μm) were enrolled; vertical hole diameters were also measured using spectral-domain optical coherence tomography (OCT). Following vitrectomy, ILM peeling was performed over a horizontally oval area (additional 1 disc-diameter temporally); perfluoropropane gas (C3F8, 15%) tamponade was used. Hole closure and change in best-corrected visual acuity (BCVA) were monitored after absorption of the gas. Preoperative and postoperative visual acuities were compared using paired t-test. IBM SPSS (ver. 26) was used for analysis. Results: The macular holes were horizontally oval rather than circular without exception: mean horizontal and vertical diameters were 714 μm (range: 600–1020 μm) and 602 μm (490–844 μm), respectively. Following vitrectomy, macular hole closure was obtained in 20/21 eyes by the last follow-up (mean: 28 months, median: 34 months; range 4–48 months). Mean Snellen BCVA improved from 20/200 to 20/63 (P < 0.0001). Conclusion: All the macular holes in the study were observed to be horizontally oval. A corresponding horizontal enlargement of the ILM rhexis yielded excellent anatomical and satisfactory visual outcomes.

Abstract
Surgical treatment is generally necessary to repair full-thickness macular holes (FTMH). Although vitrectomy with or without internal limiting membrane (ILM) peeling remains the standard surgical technique, the inverted ILM flap procedure has increasingly assumed a role in the primary surgical repair of FTMHs. Some vitreoretinal surgeons reserve this technique to treat large or myopic holes, whereas others use it routinely in all cases. This paper is a comprehensive review of the current scientific evidence on the anatomical and functional outcomes of the inverted ILM flap technique in the repair of macular holes, following the International Vitreomacular Traction Study (IVTS) group classification.

Nasal or Temporal Internal Limiting Membrane Flap Assisted by Sub-Perfluorocarbon Viscoelastic Injection for Macular Hole Repair. Am J Ophthalmol 2021; 223:296-305. [PMID: 32950511 DOI: 10.1016/j.ajo.2020.09.023] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 09/07/2020] [Accepted: 09/10/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To compare the outcomes between using a nasal and a temporal inverted internal limiting membrane (ILM) flap both assisted by a novel technique in repairing a full-thickness macular hole (FTMH). DESIGN Retrospective interventional case series. METHODS Thirty-nine eyes from 39 patients with a FTMH <600 μm were included from a single institution. All patients underwent vitrectomy using a semicircular single-layered ILM inverted flap assisted by a sub-perfluorocarbon liquid injection of ophthalmic viscoelastic device (OVD) technique. Best-corrected visual acuity (BCVA) and spectral domain optical coherence tomography were used to compare outcomes between nasal (n = 19) and temporal (n = 20) groups. RESULTS At 6 months postoperatively, all FTMHs closed and BCVA were significantly improved. Overall, 36 eyes (92%) achieved U-shaped closure, and ellipsoid zone restoration was noted in 24 eyes (62%). An ILM flap was present in 29 eyes (74%) and 86% remained single-layered. There were significantly more deep inner retinal dimples in the temporal group (35%) compared with 5% in the nasal group (P = .04), but these were unrelated to BCVA. Significant retinal thinning in the temporal outer sub-field was noted in the temporal group and was negatively correlated with BCVA (rho [ρ]: - .53; P = .03). No significant postoperative retinal displacement was noted in either group. CONCLUSIONS The technique of using sub-perfluorocarbon liquid injection of OVD secured single-layered flaps intraoperatively and postoperatively. Both the nasal and temporal inverted ILM flaps repaired FTMH and improved visual acuity. However, both temporal macular thinning and deep inner retinal dimples were significantly greater in the temporal group.

Abstract
BACKGROUND Biomarkers are characteristic biological measurable signs and objective parameters to detect the state of health. Besides functional and temporal factors, imaging biomarkers play an increasingly important role. In full-thickness and lamellar defects of the macula numerous imaging parameters have been described. This knowledge resulted in new classifications for both clinical pictures, which are based on important biomarkers of these clinical pictures and characteristic features of described subtypes. METHODS Imaging biomarkers for full-thickness and lamellar macular defects are described with respect to the classification and their functional prognostic importance. The importance of these biomarkers is presented. RESULTS The current classification of full-thickness and lamellar macular defects is based on structural biomarkers. Biomarkers are important for prognostic and therapeutic evaluation and they have an impact on the surgical strategy. There are various surgical strategies for treatment of full-thickness macular holes depending on the size of the foramen and other biomarkers. The inverted ILM flap technique improves the closure rate of large macular holes. In lamellar macular holes showing signs of progression an early surgical intervention results in a good anatomical and functional prognosis. CONCLUSION Multimodal diagnostics provide important preoperative, intraoperative, and postoperative features for macular holes and lamellar macular holes, which are essential biomarkers for the exact classification, the therapeutic strategy and for assessment of the prognosis.
