ABSTRACT

Purpose: To evaluate the impact of the inverted internal limiting membrane (ILM)?flap technique on the visual outcome and anatomical recovery for small (<250 ?), medium (<400 ?), and large (>400 ?) macular holes (MHs). Methods: Retrospective study included consecutive idiopathic MH cases operated on using the inverted ILM?flap technique. Clinical data were retrieved from electronic medical records (EMRs), surgical videos, and optical coherence tomography (OCT) machines. Eyes with axial length >25 mm, coexisting macular diseases, and follow?up <6 weeks were excluded. Data included the presence or absence of ILM flap and restoration of External Limiting Membrane (ELM), Ellipsoid Zone (EZ) lines. Mean visual improvement and structural recovery were compared between eyes showing ILM flap and those showing no flap in three MH size groups. Results: Forty eyes of 38 patients with a mean age of 62.7 ± 10.1 years and a mean MH diameter of 348 ± 152 ?m were included. The mean follow?up was 527 ± 478 days with anatomical closure observed in all eyes. Mean best?corrected visual acuity (BCVA) improved significantly from 0.87 ± 0.38 to 0.35 ± 0.26. ILM flap was visible in 29 (72.5%) all MHs, 7 (53.8%) small MHs (n = 13), 8 (61.5%) medium MHs (n = 13), and 14 (100%) large MHs (n = 14). The mean BCVA change was 0.47 ± 0.34, 0.53 ± 0.48, and 0.56 ± 0.20 in large, medium, and small MHs, respectively, and the difference between eyes showing ILM flap versus no flap in each MH size group was not statistically significant (P > 0.05). However, for medium MHs, it was higher in the ILM flap (0.66 ± 0.52) group compared to the no flap (0.32 ± 0.37) group. One eye with small MH developed significant gliosis resulting in reduced BCVA. ELM was restored in all eyes with small and medium MHs. Conclusion: We observed that the ILM flap did not adversely affect anatomical and visual outcomes for MHs <400 ?m. Restoration of ELM suggests minimal interference in structural recovery by an ILM flap.

ABSTRACT

Purpose: We report clinical characteristics, risk factors, treatment outcomes, and prognostic predictors of post?vitrectomy secondary macular holes (MHs). Methods: This was a retrospective observational case series from November 2014 to December 2020. Eyes that developed secondary MH, two weeks and beyond after primary vitrectomy for non?MH indications, were enrolled. Pre? and intraoperative records were screened to exclude pre?existence of MH. Eyes with multiple vitreoretinal surgeries prior to MH detection and tractional myopic maculopathy were excluded. Results: A total of 29 eyes of 29 patients with a mean age of 52 years developed secondary MH post?vitrectomy. The most common indications for primary vitrectomy were rhegmatogenous retinal detachment (RRD, 48.2%) and tractional retinal detachment (TRD, 24.1%). Time to MH detection after primary vitrectomy was 91.5 ± 117.6 days. The mean minimum hole diameter was 530 ± 298 microns. Epi?retinal membrane and cystoid degeneration was noted in 6 (20.7%) and 12 (41.3%) eyes, respectively (p = 0.088). The mean time from MH detection to MH repair was 34 ± 42 days. The surgical intervention included internal limiting membrane peeling with tamponade in 25 eyes. Overall, 80% showed anatomic hole closure, 90.9% versus 57.1% in the RRD and TRD (p = 0.092), respectively. The mean best?corrected visual acuity (BCVA) at the final visit was 0.71 logarithm of the minimum angle of resolution. Thirteen eyes (52%) had a BCVA of 20/100 or better. Minimal hole diameter (p = 0.029) only predicted final visual acuity. The interval between MH diagnosis and repair did not affect hole closure significantly (p = 0.064). Conclusion: Secondary MH post?vitrectomy closed successfully with limited visual improvement and trails behind idiopathic MH.

ABSTRACT

Purpose: To analyze and describe the proteome of the vitreous humour in eyes with idiopathic macular holes. Methods: We performed mass spectrometry (MS)?based label?free quantitative analysis of the vitreous proteome of idiopathic macular hole (IMH) and control donor vitreous. Comparative quantification was performed using SCAFFOLD software which calculated fold changes of differential expression. Bioinformatics analysis was performed using DAVID and STRING software. Results: A total of 448 proteins were identified by LC?MS/MS in IMH and cadaveric eye vitreous samples, of which 199 proteins were common. IMH samples had 189 proteins that were unique and 60 proteins were present only in the control cadaveric vitreous. We found upregulation of several extracellular matrix (ECM) and cytoskeletal proteins, namely collagen alpha?1 (XVIII) chain, N?cadherin, EFEMP1/fibulin?3, basement membrane?specific heparan sulfate proteoglycan core protein, and target of Nesh?3. Several cytoskeleton proteins, namely tubulin, actin, and fibronectin levels, were significantly lower in IMH vitreous, probably reflecting increased ECM degradation. IMH vitreous also had a downregulation of unfolded protein response?mediated?mediated apoptosis proteins, possibly related to a state of increased cell survival and proliferation, along with a remodelling and aberrant production of ECM contents. Conclusion: The pathogenesis of macular holes may involve ECM remodelling, epithelial–mesenchymal transformation, downregulation of apoptosis, protein folding defects, and complement pathway. The vitreo?retinal milieu in macular holes contain molecules related to both ECM degradation and inhibition of the same, thereby maintaining a homeostasis.

ABSTRACT

Purpose: To compare the outcomes of papillomacular bundle (PMB) sparing internal limiting membrane (ILM) peeling (group LP) and conventional ILM peeling (group CP) for treatment of idiopathic macular hole (MH) of ?400 ?m. Methods: Fifteen eyes were included in each group. In group CP, conventional 360° peeling was done, while in group LP, ILM was spared over PMB. The changes in peripapillary retinal nerve fiber layer (pRNFL) thickness and ganglion cell?inner plexiform layer (GC?IPL) thickness were analyzed at 3 months. Results: MH was closed in all with comparable visual improvement. Postoperatively, retinal nerve fiber layer (RNFL) was significantly thinner in the temporal quadrant in group CP. GC?IPL was significantly thinner in the temporal quadrants in group LP, whereas it was comparable in group CP. Conclusion: PMB sparing ILM peeling is comparable to conventional ILM peeling in terms of closure rate and visual gain, with the advantage of less retinal damage at 3 months.

ABSTRACT

Purpose: To compare the anatomical, morphological, and functional outcomes of the conventional internal limiting membrane (ILM) peeling versus temporal inverted ILM flap technique for large full?thickness macular holes (FTMHs). Methods: Sixty eyes of 60 patients with a minimum base diameter >600 ?m were included in this retrospective interventional study. Patients were divided into conventional ILM peeling (Group 1) and temporal inverted ILM flap (Group 2) groups. 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 24/32 (75.0%) cases of Group 1 and 27/28 (96.4%) cases of Group 2 (P = 0.029). The mean BCVA (logMAR) changed from 1.23 ± 0.47 to 0.70 ± 0.29 logMAR in Group 1 and from 1.03 ± 0.36 to 0.49 ± 0.24 logMAR in Group 2 at 6 months (P < 0.001 in both cases). U?shaped closure was observed in 5 (15.6%) eyes in Group 1 and 19 (67.9%) 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 = 0.002, P = 0.001, respectively). Conclusion: The study results suggested that the FTMH closure rate, recovery of the outer retinal layers, and, consequently, the post?operative BCVA were better with the temporal inverted ILM flap technique than with the conventional ILM peeling for larger than 600 ?m macular holes.

ABSTRACT

AIM: To investigate the clinical efficacy of pars plana vitrectomy(PPV)combined with inverted internal limiting membrane flap technique in the treatment of macular hole retinal detachment(MHRD)in high myopia.METHODS: A retrospective clinical study was conducted. A total of 63 patients(64 eyes)with high myopia and MHRD who treated at our hospital from October 2017 to October 2021 were selected as research subjects. They were divided into two groups according to different surgery, with 34 cases(35 eyes)who received PPV combined with inverted internal limiting membrane flap technique in group A, and 29 cases(29 eyes)received PPV combined with internal limiting membrane peeling in group B. The patients were followed up for 6mo. The two groups were compared in terms of the hole closure rate, the reduction rate of retinal detachment and best corrected visual acuity(BCVA)before operation and at 1wk, 1, 3 and 6mo after operation, and the postoperative complications were recorded.RESULTS: The hole closure rate within 6mo after operation was significantly higher in group A than in group B(P&#x0026;#x003C;0.05), but there was no statistically significant difference in the reduction rate of retinal detachment(P&#x0026;#x003E;0.05). The BCVA of the two groups was significantly improved over time after operation(P&#x0026;#x003C;0.05). There was no statistically significant difference in BCVA between the two groups before operation and at 1wk, 1, 3 and 6mo after operation(P&#x0026;#x003E;0.05). Complications were observed in the two groups, but there was no statistically significant difference in the incidence of complications between the two groups(P&#x0026;#x003C;0.05).CONCLUSION: PPV combined with inverted internal limiting membrane flap technique is safe and effective in the treatment of MHRD in high myopia, which can effectively improve the patients' BCVA and the hole closure rate without influence on intraocular pressure.

ABSTRACT

Purpose: To report a case of Alport syndrome presenting with bilateral giant full-thickness macular holes, hypertensive chorioretinopathy, and exudative retinal detachment. Case Report: A 20 year-old man, a known case of Alport syndrome on hemodialysis, was referred to our clinic with bilateral vision loss initiated about 10 years prior to presentation, which exacerbated in the month prior to our visit. Bilateral large full-thickness macular holes, hypertensive chorioretinopathy, and exudative retinal detachment were detected in fundus examination. The patient had previous genetic counseling confirming the diagnosis of Alport syndrome. During follow-up, macular holes were covered with a thick epiretinal membrane and visual acuity decreased progressively in two weeks. Pars plana vitrectomy was performed in the right eye. Two weeks following surgery, the macular hole was closed and visual acuity improved significantly. Conclusion: Bilateral giant full-thickness macular holes are uncommon presentations of Alport syndrome. The retinal findings may be caused by an inefficient type IV collagen presenting in the Bruch's membrane and in the internal limiting membrane. Pars plana vitrectomy can be considered to repair macular holes in these patients.

ABSTRACT

AIM: To observe the visual improvement and anatomical closure of patients with full-thickness macular hole(FTMH)accompanied by lamellar hole-associated epiretinal proliferation(LHEP)after vitrectomy.METHODS: A retrospective study of clinical cases. A total of 28 cases(28 eyes)of patients diagnosed with FTMH in our hospital between January 2018 and January 2022 were included, and they were divided into 12 cases(12 eyes)in the LHEP group and 16 cases(16 eyes)in the non-LHEP group according to the presence or absence of LHEP. All subjects had undergone vitrectomy. The best corrected visual acuity(BCVA)before and 1a after operation, hole closure, continuity of ellipsoid zone and external limiting membrane(ELM), intraocular pressure(IOP), and postoperative complications were compared between the two groups.RESULTS: Preoperative BCVA(LogMAR)was 0.80±0.17 in the LHEP group and 0.92±0.27 in the non-LHEP group(t=1.406, P=0.172); BCVA at 1a after operation was 0.54±0.14 in the LHEP group and 0.39±0.10 in the non-LHEP group(t=3.399, P=0.002). BCVA at 1a after operation was significantly improved in both groups compared with that before operation(tLHEP group=4.029; PLHEP group=0.001; tnon-LHEP group=7.445, Pnon-LHEP group=0.001); the difference in BCVA(LogMAR)before and after the operation was 0.27±0.16 in the LHEP group and 0.52±0.26 in the non-LHEP group(t=3.153, P=0.002). The hole closed in both groups 1a after the operation, and the closure rate was 100%. The ellipsoid zone closed in 20%(2/12)of patients in the LHEP group and 56%(9/16)in the non-LHEP group(Pellipsoid zone=0.04); the ELM closed in 25%(3/12)of patients in the LHEP group and 69%(11/16)in the non-LHEP group(PELM=0.027). A postoperative transient IOP elevation occurred in 2 eyes of the LHEP group and 3 eyes of the non-LHEP group, respectively. There were no significant cataract or serious complications after the vitrectomy in either group.CONCLUSIONS: Compared with FTMH patients without LHEP, the BCVA improvement after vitrectomy was less in FTMH patients with LHEP. Although their macular hole was closed, the closure rates of ellipsoid zone and ELM were lower, and the duration of continuity interruption was longer, so the prognosis requires further clarification.

ABSTRACT

AIM: To analyze the application value of spectral domain-optical coherence tomography(SD-OCT)parameters on evaluating visual acuity improvement after internal limiting membrane peeling of macular hole.METHODS: The retrospective analysis was performed on the clinical data of 82 patients(82 eyes)with idiopathic macular hole(IMH)who underwent vitrectomy + internal limiting membrane peeling + long-acting gas tamponade in the hospital between May 2019 and February 2021. The correlation between IMH closure and SD-OCT parameters at 3mo after surgery was analyzed, and the risk factors for poor postoperative visual acuity improvement were evaluated.RESULTS: Spearman rank correlation coefficient analysis showed that IMH closure at 3mo after operation was positively correlated with preoperative external limiting membrane(ELM)defect diameter(rs=0.308, P&#x003C;0.05), and it was negatively correlated with preoperative macular hole index(MHI; rs=-0.266, P&#x003C;0.05). Logistic regression analysis revealed that preoperative MHI≥0.5 was a protective factor affecting poor postoperative visual acuity improvement(OR=0.691, P&#x003C;0.05).CONCLUSION: SD-OCT can predict the surgical efficacy by detecting the preoperative MHI and ELM defect diameter, and it is beneficial to judging the improvement of visual function.

ABSTRACT

Objective:To observe the clinical effects of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling and C 3F 8 tamponade for patients with highly myopic macular hole (HM-MH) with and without foveoschisis. Methods:A retrospective case controlled study. From January 2017 to February 2022, 23 eyes of 23 patients with highly myopic macular hole with and without foveoschisis diagnosed in the Shandong Eye Hospital were included in the study. Among them, 5 males had 5 eyes, and 18 females had 18 eyes, the age was (54.43±12.96) years old. The patients with or without foveoschisis were 12 eyes in 12 cases and 11 eyes in 11 cases. Studies were divided into two groups, depending on the presence of a concomitant myopic foveoschisis or not. The groups are high myopia macular hole with foveoschisis (group A) and high myopia macular hole without foveoschisis (group B). Best-corrected visual acuity (BCVA), B-scan ultrasonography, optical coherence tomography and axial length (AL) measurement were performed in all eyes. Snellen chart was used for BCVA examination, and the visual acuity was converted into logarithm of minimum angle of resolution (logMAR) during statistics. The age of the two groups, sex, macular hole (MH) diameter, logMAR BCVA, AL, posterior scleral staphyloma, there was no significant difference ( P>0.05). PPV combined with ILM peeling and C 3F 8 filling were performed in all eyes. Follow-up was at least 3 months after the last operation. BCVA changes and MH closure were compared between the two groups after surgery. Wilcoxon test was used to compare BCVA before and after operation. Mann-whiteny U test was used to compare preoperative and postoperative BCVA between groups. Results:After initial surgery, MH was closed in 17 of 23 eyes (74%, 17/23). MH was closed in 8 eyes in group A (66.7%, 8/12). Four eyes were not closed (33.3%, 4/12); MH closed in 9 eyes in group B (81.8%, 9/11). There was no significant difference between the two groups after initial operation ( P>0.05). At 1 and 3 months after surgery, the logMAR BCVA of patients in group A and group B were 1.00±0.46, 1.03±0.83 and 0.53±0.63, 0.55±0.41, respectively. Compared with before operation, there was no significant difference at 1 month ( P=0.783, 0.358), but the difference was statistically significant at 3 months ( P=0.012, 0.007). There was no significant difference in logMAR BCVA between group A and group B at 1 and 3 months after operation ( P=0.687, 0.950). Conclusion:PPV combined with ILM peeling and C 3F 8 tamponade can promote MH closure and improve visual acuity in most affected eyes with HM-MH with and without foveoschisis.

ABSTRACT

Purpose: To evaluate the absence of external limiting membrane (ELM) and ellipsoid zone (indistinct retinal outer layers, I?ROL) in the walls of idiopathic full?thickness macular holes (FTMHs) circumferentially on optical coherence tomography (OCT) and its correlation with surgical outcome. Methods: In this retrospective observational study, OCT images of patients undergoing vitrectomy for FTMHs with at least 3?months of postoperative follow?up were analyzed for preoperative circumferential extent of I?ROL. Derived macular hole indices such as hole form factor (HFF), macular hole index (MHI), tractional hole index (THI), and hole diameter ratio (HDR) were also calculated. The circumferential extent of I?ROL was correlated with derived hole indices as well as anatomical closure, foveal architecture, and restoration of ELM following surgery. Results: All nine eyes (eight patients) with FTMH (mean size: 610.11 ± 122.95 microns) in the study showed I?ROL in ?1 quadrant. The mean HFF, MHI, THI, and HDR values were 0.72 ± 0.09, 0.35 ± 0.05, 0.71 ± 0.24, and 0.53 ± 0.14, respectively. All eyes achieved type?1 hole closure with improvement in best?corrected visual acuity to 0.58 ± 0.32 LogMAR from 0.81 ± 0.26 LogMAR. Regular foveal architecture was achieved in six eyes. Out of these, five eyes had I?ROL in ?2 quadrants, and one eye had I?ROL in <2 quadrants (P = 0.0476). Restoration of ELM was seen in aforementioned six eyes (complete = 5, partial = 1). Out of the five eyes with complete ELM restoration, four had a circumferential extent of I?ROL in ?2 quadrants (P = 0.0476). Complete restoration of ELM was associated with the complete restoration of the ellipsoid zone in three eyes. Conclusion: Preoperative circumferential extent of I?ROL in FTMH walls can be a potential predictive OCT marker for the type of closure, postoperative foveal architecture, and ELM restoration.

ABSTRACT

Purpose: To evaluate the success rate of autologous retinal graft (ARG) for the closure of full?thickness macular holes (MHs) and compare the outcomes of three different techniques of harvesting the graft. Methods: Clinic files of all patients who had undergone ARG for MH using intraocular scissors, membrane loop, or retinal punch to harvest retinal tissue were retrospectively reviewed. All patients were evaluated for MH closure, retinal reattachment, and visual improvement. Results: Twenty?two eyes of 22 patients were included. ARG was done for 16 eyes (72.7%) with failed, large persistent MH, and six eyes (27.3%) also underwent simultaneous repair of retinal detachment. The basal diameter of MH was 1103.67 ± 310.09 (range 650–1529) ?m. Intraocular scissors were used in 10 eyes (45.5%), a membrane loop in five eyes (22.7%), and a retinal punch in seven eyes (31.8%). Silicone oil tamponade was used in seven (31.8%) eyes and gas in 15 (68.1%) eyes. The follow?up ranged from 6 to 18 months. The hole closure rate was 72.7% (16/22). Visual improvement was noted in 18 eyes (81.8%). Retinal reattachment was seen in all eyes. Good graft integration with the surrounding area was seen in 17 eyes (77.3%). Graft retraction was seen in four eyes (18.18%) and graft loss in one eye (4.55%). No significant differences were noted among the three groups. Conclusion: ARG is successful in closing large, failed MH with and without retinal detachment. A membrane loop and retinal punch are equally useful in harvesting the graft, but scissors are preferable in case the retina is detached. With all three techniques, integration of the graft with the surrounding tissue can be achieved

ABSTRACT

Purpose: To evaluate the functional and anatomical outcomes for autologous retinal autograft with Finesse™ Flex Loop for failed macular holes. Methods: This is a retrospective study analyzing medical records of consecutive patients with refractory macular hole (at least 1 prior surgery) and eyes with retinal detachment with coexisting macular holes (MH). Optical coherence tomography (OCT) of the macula was performed before and after surgery. The primary study outcome evaluated were the functional and anatomic macular hole closure, and secondary outcomes were improvement in visual acuity and restoration of the outer retinal bands, external limiting membrane, and ellipsoid zone in eyes with acquisition of autologous retinal transplant using Finesse Loop. Results: The study included eight eyes of eight patients; retinal autograft was performed in six (75.0%) and autologous retinal transplantation (ART) with rhegmatogenous retinal detachment (RRD) was performed in two (25.0%) eyes. The average MH basal diameter in the study was 1310.88 ± 138.63 ?m. The successful hole closure rate was observed to be 75% (6 eyes) and 100% retinal reattachment was observed in ART with RRD. Statistically significant (P = 0.001) improvement was noted for preop and postop visual acuity gain for ART acquisition and postop macular hole closure. The restoration of the external limiting membrane (ELM) and ellipsoid zone (EZ) was observed in 37.5% (3 eyes) of patients. Conclusion: Finesse™ Flex Loop can be used to harvest retinal tissue and it provides good anatomical and functional outcomes for failed macular hole.

ABSTRACT

Purpose: Vitreomacular interface disorders have long been argued to change choroidal structure. The aim of this study was to determine the choroidal vascularity index (CVI) changes following internal limiting membrane peeling for epiretinal membrane (ERM) and full thickness macular hole (FTMH). Methods: Fifty-nine patients with unilateral ERM and 56 with unilateral FTMH were included in the study. Axial length, pre- and post-surgery intraocular pressure, baseline and post-phacovitrectomy CVI were calculated and compared with the normal fellow eyes. To compare the baseline and the final measurements, Wilcoxon test was used. Mann–Whitney U test was used for independent data comparisons. Median and standard deviations were compared. Results: Axial length, pre- and post-surgery intraocular pressure differences were insignificant between study and fellow eyes within all groups. CVI were significantly lower in post-vitrectomy study eyes of all groups compared with pre-surgery (P < 0.001). There were no significant changes before and after the surgeries in fellow eyes. Baseline CVI of ERM study eyes (median 65.90%) and FTHM study eyes (median 65.59%) did not differ significantly between groups (U = 1336, P = 0.07, r = 0.16). Conclusion: There are conflicting results of vitreoretinal interface disorders CVI in the literature. In this study, both FTMH and ERM eyes showed reduced CVI postoperatively compared with the baseline. Preoperatively, there were no difference between study eyes and the fellow eyes.

ABSTRACT

Purpose: To analyze the effect of various macular hole indices and postoperative microstructural changes of all retinal layers on postoperative functional outcomes in patients with idiopathic full?thickness macular hole (FTMH). Methods: In this prospective study, pre and post?operative optical coherence tomography (OCT) scans of 36 eyes with idiopathic FTMH were analyzed. Hole indices and microstructural changes of all retinal layers such as ellipsoid zone (EZ), external limiting membrane (ELM) integrity, outer and inner retinal defects, and cystoid resolution were studied on follow?up visits. Results: Out of 36 eyes, type?1 closure was achieved in 23 eyes (65.7%) and type?2 closure in 11 eyes (31.42%), one eye showed persistent hole, and one eye was lost to follow?up. The mean minimum diameter of hole (P = 0.026), mean MHI (P = 0.001), DHI (P = 0.158), THI (P = 0.001), and HFF (P < 0.001) showed statistical significance with the type of hole closure. Postoperatively, eyes with intact ELM and EZ had better BCVA at the final visit. The BCVA was better by logMAR 0.73 ± 0.38 (P < 0.001) in patients with absent outer retinal defects. There was a significant difference in BCVA of 0.52 ± 0.35 at 1 month and 0.64 ± 0.34 at 6 months in eyes without inner retinal defects (P < 0.001). At 6 months, cystoid resolution was observed in 28 (80%) eyes. BCVA was significantly better at 1 month (P < 0.001) and at 6 months (P = 0.001) in eyes with no DONFL. Conclusion: Macular hole indices determine the closure type. Postoperative regeneration of outer retinal layers and resolution of retinal defects significantly influence the final visual outcomes. ELM recovery is seen as a prerequisite for EZ regeneration with no new IRD after a period of 3 months

ABSTRACT

Background: Blunt trauma to the eye can present with varied manifestations involving both the anterior and posterior segments of the eye. Giant retinal tear (GRT) following trauma occurs most commonly at the equatorial region or anterior to the equator. GRT posterior to the equator is rare. Purpose: To demonstrate the successful management of a post?traumatic posterior GRT and full?thickness macular hole (MH) associated retinal detachment (RD). Synposis: A 21?year?old?male presented with sudden diminution of vision in the right eye (RE) following blunt?trauma with cricket ball. RE vision at presentation was hand movement close to face. Anterior segment of RE revealed pupillary sphincter tear, posterior synechiae and posterior subcapsular cataract (PSC). RE fundus revealed a posterior?GRT, full thickness MH, mild vitreous haemorrhage and rhegmatogenous RD. He was managed with pars plana vitrectomy, encircling scleral band, perfluorocarbon liquid?assisted flattening of GRT, internal limiting membrane peeling, and endotamponade. Post?operatively the retina was attached, MH was closed and the patient achieved an ambulatory vision of 1/60. Highlights: This video demonstrates the successful management of a posterior?GRT and MH associated RD. Removal of adherent hyaloid from the long anterior flap of posterior GRT, peeling of ILM from temporal narrow mobile strip of retina (which has a risk of radial extension of GRT edges) and manoeuvring in suboptimally dilated pupil are illustrated in this video.

ABSTRACT

Purpose: To evaluate the outcome of vitrectomy with multilayered inverted internal limiting membrane flap technique (ML?IILM) versus vitrectomy with standard ILM peeling for large macular holes in terms of visual acuity and anatomical closure. Methods: A hospital?based, prospective, randomized, interventional study was conducted during three calendar years with a total 150 eyes (75 in each group) in two groups—vitrectomy with ILM peeling (Group A) and vitrectomy with ML?IILM flap technique (Group B) after informed consent of study participants who met the inclusion criteria. Results: The mean minimum and maximum diameter of macular hole did not differ statistically in both the groups. Macular hole index had no significant difference between both groups Pre?operative visual acuity was not statistically significantly different between the two groups. During follow?up, best corrected visual acuity (BCVA) at 1 month, 3 months, 6 months, and 12 months was significantly better in Group B (0.12 ± 0.07 at 1 month, 0.14 ± 0.10 at 3 months, 0.18 ± 0.11 at 6 months, and 0.19 ± 0.12 at 12 months) compared to Group A (0.20 ± 0.11 at 1 month, 0.22 ± 0.13 at 3 months, 0.30 ± 0.12 at 6 months, and 0.31 ± 0.14 at 12 months) (P = 0.001 for each). Type 1 anatomical closure (flattening of cuff and opposition of edges of hole) was achieved in 78.66% (59/75) cases in Group A and 93.33% (70/75) cases in Group B (P 0.0016). Conclusion: Vitrectomy with multilayered inverted ILM flap technique had significantly higher anatomical closure and better visual outcome than vitrectomy with standard ILM peeling

ABSTRACT

We demonstrate a modified internal limiting membrane (ILM) inverted flap technique for closure of macular holes (MHs) concurrent with rhegmatogenous retinal detachment in myopic eyes. Multiple ILM flaps were created in a flower?petal configuration around the MH over the detached retina after shallowing the retina as much as possible. Traction was always in a direction that allowed the optic disc to act as an anchor to limit iatrogenic breaks and to bridge the hole with multiple, more secure flaps should one of the flaps revert or break away. The technique proved safe and efficient in MH closure in our series of eight cases. The modification described provides an effective approach for challenging myopic cases in which ILM flap creation is needed over a detached retina.

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 ?m) 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 ?m (range: 600–1020 ?m) and 602 ?m (490–844 ?m), 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
