Abstract
INTRODUCTION Inner retinal dimples (IRDs) are frequently detected after internal limiting membrane (ILM) peeling. However, the distribution of IRDs and its effect on postoperative visual function remain unclear. We aim to quantify the distribution of IRDs after ILM peeling in different macular diseases and analyze its influence on postoperative visual function. METHODS We retrospectively reviewed patients undergoing vitrectomy with ILM peeling and followed up until 12 months in our center. The distribution of IRDs were quantitatively determined using optical coherence tomography (OCT) and OCT angiography in a different sector of Early Treatment Diabetic Retinopathy Study grid. Visual function was evaluated by retinal sensitivity (RS) using microperimetry. Spearman correlation was performed between RS and IRDs within the same sectors. Multivariate linear regression analysis was performed to analyze the association between baseline characteristics and IRDs. RESULTS A total of 43 idiopathic macular hole (iMH) cases, 56 idiopathic epiretinal membrane (iERM) cases and 42 myopic foveoschisis (mFS) cases were included. IRDs increased gradually at ILM-peeled area, interrupting ganglion cell layer. Most IRDs were observed in temporal sector. A negative correlation was depicted between the increase of IRDs and the progress of RS at both perifovea and parafovea in iERM, but only at perifovea in iMH. No significant correlation between the change of IRDs and RS was found in mFS. Multivariable linear regression model showed that preoperative axial length was significantly associated with postoperative IRDs in all patients. CONCLUSIONS IRDs distributed mostly at temporal sector after ILM peeling, interrupting ganglion cell layer. IRD progression may influence postoperative RS only in iMH and iERM. Ophthalmologists may avoid temporal sector especially in eyes with normal axial length or strong ILM-ERM adherence.

Abstract
INTRODUCTION The aim of the study was to evaluate perifoveal microvasculature changes following pars plana vitrectomy with internal limiting membrane peeling for the epiretinal membrane (ERM) and macular hole (MH). METHODS This retrospective study included 59 eyes from 59 patients. Subjects were divided into two groups: an ERM group (n = 43) and an MH group (n = 16) based on the initial diagnosis. Swept-source optical coherence tomography angiography (SS-OCTA) was performed in the macular area, pre- and postoperatively. Perifoveal microvascular changes were calculated using MATLAB from the 6 × 6 mm SS-OCTA images, excluding the foveal avascular zone. Pre- and postoperative perifoveal vessel densities (pfVDs) were separately analyzed in six sectors (superior, superotemporal, inferotemporal, inferior, inferonasal, and superonasal) in the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The baseline characteristics and other clinical factors were compared between the ERM and MH groups. RESULTS The postoperative best-corrected visual acuity significantly improved in both groups (p < 0.05). One year after surgery, the pfVD in the SCP of the ERM group significantly decreased in the inferotemporal sector (p = 0.049). The postoperative pfVD in the DCP of the MH group significantly decreased in temporal sectors (p < 0.05). The postoperative mean pfVD in the SCP in the MH group was significantly lower than that in the ERM group (p = 0.003). The presence of a dissociated optic nerve fiber layer (DONFL) was 75% in the MH group and 22% in the ERM group (p = 0.018). The correlation between the pfVD and DONFL was not statistically significant. CONCLUSION Postoperative pfVD reduction in the temporal sector, a corresponding area in which DONFL is present after MH surgery, was significantly observed. After vitreoretinal surgery in MH patients, OCTA may serve as a useful tool for monitoring perifoveal microvascular changes, especially in temporal sectors.

Abstract
PURPOSE To describe presence and distribution of pores of the inner limiting membrane (ILM) in eyes with vitreomaculopathies. METHODS Inner limiting membrane specimens were harvested from 117 eyes of 117 patients during vitrectomy with membrane peeling from eyes with vitreomacular traction syndrome, idiopathic and secondary epiretinal gliosis, and idiopathic full-thickness macular hole. All specimens were processed as flat-mounts for immunocytochemistry and examined by phase-contrast, interference, and fluorescence microscopy. Demographic and clinical data were correlated. RESULTS Inner limiting membrane pores were found in all vitreomaculopathies. They were identified in 47 (40.2%) of 117 eyes being most evident with antilaminin. In eyes with full-thickness macular hole >400 µ m, pores were seen in more than half of all eyes. They occur as numerous and uniformly distributed defects of the flat-mounted ILM with a mean diameter of 9.5 ± 2.4 µ m. Edges of ILM pores are round with an irregular contour and no specific cellular pattern. Pores were distinguished from retinal vessel thinning and iatrogenic artefacts. CONCLUSION Contrary to previous reports, ILM pores are a common finding in vitreomaculopathies easily visible with antilaminin staining. Further studies are needed to clarify whether their presence correlates with differences in disease progression or imaging before and after vitrectomy with ILM peeling.

Abstract
OBJECTIVES To quantitatively evaluate concentric macular dark spots (CMDS) on spectral-domain optical coherence tomography (SD-OCT) to determine the morphological characteristics of dissociated optic nerve fibre layer (DONFL) following the performance of internal limiting membrane (ILM) peeling in patients with full-thickness idiopathic macular hole (IMH) closure. METHODS Retrospective study on patients who underwent a vitrectomy with ILM peeling procedure. BCVA, cross-sectional OCT scans, and three-dimensional reconstructions of en face OCT scans were analysed preoperatively, at 2, 6, 12 months post-operatively. A novel image analysis technique was used to automatically measure DONFL logical properties through the radius, area, the nerve fibre layer dissociation index (NFLDI), and depth of the CMDS. RESULTS 53 eyes of 51 patients were included, and the mean follow-up was 11.53 ± 6.26 months. CMDS was found in 46 (86.79%) eyes within 2 months after ILM peeling and 50 (94.34%) eyes within 6 months after ILM peeling. CMDS concentrated on the temporal side of the macula in all 50 eyes (100%) at first detection. The area, NFLDI, and depth of CMDS in four quadrants developed significantly during the postoperative 6 months (p < 0.05), and then these changes slowed down and remained unchanged 12 months post-operatively. The morphological changes in the temporal quadrant were significantly greater than those in other quadrants at 2, 6, 12 months (all p < 0.05) post-operatively. CONCLUSIONS CMDS mostly appeared and concentrated on the temporal side of the macula in IMHs within two months after ILM peeling and progressed within 6 months and remained unchanged after 12 months.

Abstract
OBJECTIVE To evaluate the long-term structural and microvascular retinal effects of internal limiting membrane peeling for full-thickness macular hole (FTMH) using en face adaptive optics optical coherence tomography (AO-OCT), conventional OCT, and OCT angiography (OCTA). DESIGN Interventional case series. PARTICIPANTS Patients with FTMH treated with vitrectomy, internal limiting membrane peeling, and gas tamponade. METHODS Eleven eyes with FTMH that had at least 12 months of postoperative follow-up were enrolled in the study. En face AO-OCT was used to image the superficial retina in the peeled and nonpeeled areas. En face structural OCT was performed to image the inner retinal dimples (IRDs), macular thickness, and retinal nerve fibre layer (RNFL). En face OCTA was used to examine the integrity of the peripapillary nerve fibre layer (NFL) plexus. RESULTS AO-OCT showed RFNL wrapping around the IRDs, and no obvious peripapillary NFL plexus dropout was seen with OCTA. Scattered hyper-reflective dots were observed on the surface of the peeled retina in all patients imaged with AO-OCT. No significant differences were found in IRD number (91.5 ± 24.4 versus 77.2 ± 14.7; P = 2.07), IRD proportionate area (8.36 ± 3.34 versus 7.53 ± 2.60; P = 0.159), or macular thickness between the 6- and 12-month (or greater) postoperative visits. CONCLUSION IRDs do not to progress beyond 6 months postoperatively, and no obvious damage to RFNL and peripapillary NFL plexus was detected. Hyper-reflective dots on the surface of the retina suggestive of possible Müller cell reactive gliosis were identified with AO-OCT.

Abstract
PURPOSE To evaluate the effect of the temporal inverted internal limiting membrane (ILM) flap technique compared with that of conventional ILM peeling on the extent of the dissociated optic nerve fiber layer (DONFL) and retinal sensitivity in patients undergoing macular hole (MH) surgery. DESIGN Single-center, prospective, open-label, randomized controlled clinical trial. PARTICIPANTS Patients requiring vitrectomy for MHs sized > 250 μm. METHODS Patients were randomly assigned (1:1) to 1 of the following 2 groups: (1) the control group undergoing standard ILM peeling and (2) the experimental group (flap group) undergoing the temporal inverted ILM flap technique. MAIN OUTCOME MEASURES The primary outcome measure was the total DONFL score at 3 months after surgery. Important secondary outcomes were microperimetry results, primary MH closure rate, external limiting membrane (ELM) and ellipsoid zone (EZ) recovery rates, and best-corrected visual acuity (BCVA). RESULTS Sixty-five patients were recruited between February 2018 and July 2020; primary outcome data were available for 60 patients. The median DONFL score was 7.0 (3.0-12.5) in the control group and 5.0 (1.5-8.5) in the flap group at 3 months after surgery (P = 0.145). The focal depressions characteristic of the DONFL were limited to the temporal side of the fovea in the flap group, whereas they were found all around the fovea in the control group on spectral-domain OCT images. The MH closure rate (P = 1), EZ and ELM recovery rates (P = 0.252), and BCVA (P = 0.450) were similar between the 2 groups. The 3-month overall median retinal sensitivity (MRS) (P = 0.142) and MRS improvement (P = 0.916) in the control group were comparable with those observed in the flap group. In addition, there was no significant difference between the 2 techniques when considering the temporal area (P = 0.105) or the nasal area (P = 0.468). CONCLUSIONS The temporal inverted ILM flap technique reduced the extent of the DONFL by preserving the nasal part of the fovea. However, the overall DONFL score was similar between the 2 techniques. In addition, the MRS and BCVA did not differ from those obtained after complete ILM peeling.

Abstract
PURPOSE To evaluate the peripapillary microvasculature changes in patients with epiretinal membrane (ERM) following pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling using swept-source optical coherence tomography angiography (SS-OCTA). METHOD Medical records and multimodal imaging data of 33 eyes after PPV for ERM were retrospectively reviewed. Peripapillary SS-OCTA images of 6×6 mm2 were recorded at at pre- and post-operatively every 6 months for 1 year. A semi-automated method was used to analyzed SS-OCTA images, excluding the optic disc area, using the MATLAB software. The peripapillary vessel density (pVD) of superficial capillary plexus (SCP) and deep capillary plexus (DCP) was quantified in four quadrants (superior, inferior, nasal and temporal). RESULT The mean pVD in SCP and DCP decreased at 6- and 12-months follow-up. In sectoral analysis, superior, inferior, and temporal quadrants pVD in SCP and DCP were significantly reduced at 1 year after vitrectomy (all p < 0.05). Meanwhile, inferior quadrants pVD in SCP and DCP showed the earliest significant reduction at 6-months (p = 0.022 and 0.048, respectively). A reduction of post-operative mean pVD in DCP was significantly greater in patients with diabetic retinopathy (p = 0.043). CONCLUSION Peripapillary capillary density significantly decreased after surgical removal of ERM. Vitrectomy with ILM peeling can cause peripapillary microvascular damage starting in inferior sector.

Abstract
Since the era when macular hole was considered untreatable, macular hole surgery has come a long way to being one of the most successful surgeries. Internal limiting membrane (ILM) peeling has been an essential step of macular hole surgery since the establishment of the role of ILM in the aetiopathogenesis and progression of macular hole. However, the novel technique was not all virtuous. It had some vices which were not evident immediately. With the advent of spectral domain optical coherence tomography, short- and long-term effects of ILM peeling on macular structures were known; and with microperimetry, its effect on the function of macula could be evaluated. The technique has evolved with time from total peeling to inverted flap to just temporal peeling and temporal flap in an attempt to mitigate its adverse effects and to improve its surgical outcome. ILM abrasion technique and Ocriplasmin may eliminate the need of ILM peeling in selected cases, but they have their own limitations. We here discuss the role of ILM in the pathogenesis of macular hole, the benefits and adverse effects of ILM peeling, and the various modifications of the procedure, to then explore the alternatives.

Abstract
Purpose: To compare conventional 360° internal limiting membrane (ILM) peeling and temporal inverted ILM flap technique with regard to postoperative foveal displacement.Methods: Patients who underwent 23 G vitrectomy with either 360° ILM peeling (Group 1) or temporal inverted ILM technique (Group 2) for idiopathic macular hole with a minimum follow up of 12 months were included. The metamorphopsia rates and distances between fovea and 3 retinal landmarks: the first retinal vascular bifurcation or crossover located superonasal and inferonasal to the fovea and ciliary vessel at the temporal margin of the disc, were compared on MultiColor SLO and near-infrared reflectance images. In addition, papillofoveal distance was measured on B-scan optical coherence tomography (OCT).Results: A total of 57 eyes were recruited (Group 1, n = 25; Group 2, n = 32). The visual acuity at month-1 was significantly higher in Group 2 than Group 1 (p = .007). A significant postoperative foveal displacement towards the disc was observed in Group 1 and Group 2 (p < .001 and p = .002 respectively). Shortening of the papillofoveal distance was greater in Group 1 than Group 2 at all postoperative visits (p < .05 for all). Furthermore, significant changes in papillofoveal distance continued until 6 months in Group 1 (p < .05 for all), whereas no significant changes occurred in Group 2 after month-1 (p > .05 for all). The complaints of metamorphopsia was significantly higher in Group 1 (n = 18/25) compared with Group 2 (n = 10/32) (p = .002).Conclusion: Temporal inverted ILM flap appear to be superior to 360° ILM peeling with regard to faster visual rehabilitation, lower rates of subjective metamorphopsia and less foveal displacement.

Abstract
PURPOSE To investigate the vascular remodeling of optical coherence tomography angiography in full-thickness macular hole surgery. METHODS This retrospective, observational case series included 33 eyes of 33 patients with a full-thickness macular hole who underwent epiretinal membrane removal. Data were collected on best-corrected visual acuity, structural B-scan optical coherence tomography, and optical coherence tomography angiography preoperatively and at 1, 3, and 6 months postoperatively. Optical coherence tomography angiography was used to assess the retinal vascular density (VD) of the superficial vascular plexus and deep vascular plexus (DVP). Vascular density was assessed using the Early Treatment Diabetic Retinopathy Study grid for the whole, inner, and outer grids. RESULTS A statistically significant correlation was found between the VD (whole, inner, and outer grids) of the superficial vascular plexus alone from baseline to 1-month postoperatively (P < 0.001). Similarly, VD was correlated from baseline to 1, 3, and 6 months postoperatively to the whole (P < 0.0005, F = 23.22), inner (P < 0.0005, F = 28.23), and outer Early Treatment Diabetic Retinopathy Study grids of DVP (P = 0.033, F = 3.49). The best-corrected visual acuity and VD were significantly correlated with the superficial vascular plexus and DVP at baseline and 6 months (P < 0.05, all correlations). The most significant correlation was observed at 6 months between best-corrected visual acuity and DVP in the whole, inner, and outer Early Treatment Diabetic Retinopathy Study grids (P < 0.001). CONCLUSION Superficial vascular plexus and DVP are affected by full-thickness macular holes, with the most significant effects being on the DVP. Full-thickness macular hole surgery leads to an improvement in the best-corrected visual acuity in many eyes and the restoration of the VD, especially of the DVP.

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
PURPOSE To evaluate sequential changes in the inner retinal surface using en face spectral domain optical coherence tomography (SD-OCT) following internal limiting membrane (ILM) peeling for idiopathic full thickness macular holes. METHODS Retrospective, interventional study on 45 eyes of 42 patients with type 1 macular hole closure after a single procedure and a minimum post-operative follow up of 6 months. Best corrected visual acuity (BCVA), fundus photographs, B scan and en face SD-OCT scans were analysed pre-operatively, at 2, 6, 12 months post-operatively and then yearly. The presence or absence of concentric macular dark spots (CMDS) on the ILM slab of en face SD-OCT, their distribution pattern and course in terms of number and size of the dark spots was qualitatively assessed at each follow up. RESULTS CMDS was identified in a total of 26 eyes (57.78%). Of these, it was detected in 21 eyes at 2 months and the remaining by 6 months. At the time of first detection, the distribution was classified as type 1 in 9 eyes (35%), type 2 in 7 eyes (27%) and type 3 in 10 eyes (38%). There was apparent increase in the number and size of the CMDS in 16 eyes (62%) no later than 12 months follow up, while 10 eyes (38%) remained stable. There was no decrease or resolution noted in any patient. The mean post-operative follow up was 19.4 months (range 6-69 months). CONCLUSION Inner retinal defects in the form of CMDS can be picked up on en face SD-OCT between 2-6 months post-operatively. They remain stable or become more prominent upto 12 months follow up, but do not regress once present. En face SD-OCT is recommended in all cases where ILM is peeled to assess CMDS.

Abstract
PURPOSE To quantitatively evaluate structural changes associated with inner retinal dimples (IRDs) and qualitatively classify the internal limiting membrane (ILM) flap configuration after temporal inverted ILM flap technique using spectral domain optical coherence tomography (SD-OCT). METHODS Twenty-three eyes of 23 patients with successfully closed idiopathic, large (>400 μm) macular hole were enrolled. Patients were treated with pars plana vitrectomy followed by temporal inverted ILM flap technique. A complete ophthalmologic examination including cross sectional and en face OCT in addition to multicolor blue reflectance imaging of confocal scanning laser ophthalmoscopy (cSLO) was performed preoperatively and at postoperative month-12. The location, number, depth, and width of the IRDs were analyzed using blue reflectance images of multicolor cSLO and en face OCT. The ILM flap is also classified as smooth, wrinkled, and folded with en face OCT. RESULTS The mean number of IRDs visualized on en face OCT (n = 23.08 ± 22.05) was statistically significantly higher compared with multicolor cSLO blue reflectance module (5.91 ± 10.58; p < 0.001). The mean depth of IRDs measured on en face OCT was 8.08 ± 3.1 μm (3-14 μm) which referred to the nerve fiber layer. The final visual acuity was associated with neither ILM flap configuration (p = 0.408), nor number of the IRDs on en face OCT (p = 0.112). CONCLUSION En face OCT is a novel imaging modality that offers improved visualization and accuracy in identifying the features of the IRDs and the ILM flap. Additionally, it provides clear visualization of the vitreoretinal interface to distinguish whether ILM was peeled or not in the initial surgery.

Abstract
Background Internal limiting membrane (ILM) peeling increases the idiopathic macular hole (IMH) closure rate but causes the inner retina dimplings. This study is to introduce a method to minimally peel the ILM, and with the ILM flap to ensure the IMH closure. Methods Twelve consecutive IMH eyes were treated with the minimal ILM peeling with ILM flap technique. The ILM around the MH is peeled off in an annular shape with a width of approximately 200 to 300 μm. A tongue-shape ILM flap is created in the superior retina and the inferior margin of ILM is not peeled off. The ILM flap is then inverted to cover the MH, followed by fluid-air exchange and air or silicon tamponade. Spectral domain-optical coherence tomography (SD-OCT) and en face OCT for morphological assessment, best corrected visual acuity (BCVA) and multifocal electroretinogram (ERG) for functional evaluation were performed at baseline and at each postoperative follow-up. Results All the 12 eyes achieved macular hole closure on SD-OCT after surgery (100%). At baseline, the mean preoperative BCVA was 0.83 ± 0.33 and it improved to 0.39 ± 0.28 postoperatively (p < 0.001). En face OCT showed the inner retinal dimplings were localized only in superior ILM-free retinas (7 eyes). The mERG response density in the central (R1), para-central (R2), R1/R2 ring ratios were remarkably improved at the last follow-up (p = 0.001, p = 0.033, p = 0.018, respectively). Conclusions The minimal ILM peeling with ILM flap technique can achieve favorable MH closure with less inner retinal dimplings and has promising visual recovery for IMH eyes.

J Ophthalmol 2019; 2019:3821479.

Abstract
AIM To summarize the spectrum of optical coherence tomography (OCT) and OCT angiography (OCTA) features after full-thickness macular hole (MH) repair surgery. METHODS A PubMed engine search was carried out using the terms "Macular Hole," "Optical Coherence Tomography," and "Optical Coherence Tomography Angiography." All reports published in English up to October 2018, irrespective of their publication status, were included. Tomographic signs analyzed were divided according to the involved portion of the retina in "inner retinal layers" and "external retinal layers." Despite predominantly involving the inner retinal layers, cystoid macular edema (CME) has been treated as a separate entity. Finally, report on vessel density (VD) changes and the foveal avascular zone (FAZ) area modifications have been included. RESULTS Different clinical findings can be observed on OCT of patients who underwent MH repair surgery. There is general consent that retinal thinning involving primarily the retinal nerve fiber layer and the ganglion cell layer takes place after surgery. In the postoperative period, the outermost retinal layers get progressively restored. Persistent defects in the ellipsoid zone or in the external limiting membrane correlate with worse postoperative visual outcome. OCTA has globally demonstrated that eyes after MH closure show a reduction in macular and paramacular VD and smaller FAZ areas, compared with control or fellow eyes. CONCLUSION Clinicians should be aware of the most common tomographic findings to properly manage each condition. In addition, significant advantages for the postoperative application of OCT and OCTA include noninvasiveness, rapid and simple execution, repeatability, and precise measurements.
