Purpose: To analyze anatomical and functional outcomes of cryopreserved human amniotic membrane (hAM) transplant in refractory macular hole (MH) surgery, present retinal layers structure after MH closure, identify visual acuity improvement determinants and complication rate., Methods: Prospective and interventional case series including seventeen patients: 13 refractory and 4 chronic (8, 15, 18 and 30-years) MH. All patients underwent vitrectomy, hAM subretinal transplant, tamponade and positioning. Complete ophthalmological examination, axial length, best-corrected visual acuity, retinography, optical coherence tomography (OCT) and autofluorescence were recorded., Results: Mean follow-up was 31 months (range 6-53). Mean LogMAR visual acuity (1.71 ± 0.42) improved significantly (1.13 ± 0.41) (P < 0.001). Patients with better baseline BCVA ended up with better final BCVA (P = 0.018). Mean MH minimum linear diameter was 831 ± 252 μm and base diameter was 1409 ± 358 μm. MH closed in all patients. Transitory ocular hypertension in one patient and transient vitreous cavity haemorrhage in another were the only postoperative complications. OCT matched scans showed plug integration and inner retinal layers rearrangement. MH size did not correlate with final BCVA. Autofluorescence showed no developing atrophy signs during long-term follow-up., Conclusion: Cryopreserved human amniotic membrane transplant may be a valuable approach to achieve macular hole closure and visual acuity improvement in refractory MH., Key Messages: What is known Human amniotic membrane transplantation is a recent surgical technique for refractory, chronic or extra-large macular holes. This surgical procedure has a shallow learning curve, high macular hole closure rate, does not require silicone oil tamponade and has very low complication rate. What is new Subretinal amniotic membrane transplant technique was successful at closing all patients' macular holes and improving visual acuity. Concerning final visual acuity predictors neither preoperative characteristics, namely the macular hole size or duration, etiology, lens status or axial length, nor surgical procedure modifications such as flap shape or tamponade lead to different outcomes. Our series included patients with refractory macular holes due to failed extended ILM peeling, failed inverted flap technique, failed autologous retinal transplant and failed epiretinal amniotic membrane transplant suggesting the technique's effectiveness in challenging refractory cases., Competing Interests: Declarations.

Purpose: To report the efficacy of Descemet's Membrane (DM) transplantation over the macular hole in patients with recurrent high myopic macular hole (HMMH) associated with retinal detachment (RD)., Methods: Six eyes of six patients with wide posterior staphyloma including MH and recurrent HMMH associated with RD were included to this retrospective study. All patients underwent pars plana vitrectomy and DM obtained from eye bank was placed over the macular hole during the surgery. Silicone oil endotamponade was used as endotamponade and removed within 6 months following surgery. Pre-operative and post-operative ophthalmologic examination and optical coherence tomography findings were recorded., Results: The mean follow-up time was 18.53 ± 7.36 months. Macular hole closure was achieved in all patients (100%). Best-corrected visual acuity was improved from 1.51 ± 0.55 logMAR to 1.08 ± 0.50 logMAR (p = 0.043). No complications due to surgery or DM during follow-up. No DM dislocation or hole re-opening occurred after surgery., Conclusion: DM transplantation during vitrectomy may be an effective treatment for the recurrent HMMH associated with RD., Key Messages: What is known Various surgical techniques have been tried for recurrent high myopic macular hole associated with retinal detachment, but satisfactory anatomical and functional success rates have still not been achieved., What Is New: The study demonstrates that Descemet's membrane transplantation is a safe and effective option for treating recurrent high myopic macular hole associated with retinal detachment. This is a novel technique that may overcome the limitations of existing approaches. The findings suggest that Descemet's membrane transplantation could become a promising addition to the surgical options for recurrent high myopic macular hole associated with retinal detachment., Competing Interests: Declarations.

Background: The aim of this study is to evaluate long-term anatomical and functional outcomes of autologous internal limiting membrane (ILM) transplantation in refractory highly myopic macular holes (HMMHs)., Methods: Retrospective interventional analysis of 13 eyes with refractory HMMH undergoing autologous ILM transplantation with gas tamponade. Best-corrected visual acuity (BCVA, Snellen), optical coherence tomography and fundus photography were scheduled at baseline and every follow-up visit (1, 3, 6, 12, 18, 24 months and the most recent). Preoperatively, we collected minimum linear diameter (MLD) and basal diameter (BD). Post-operatively, rates of external limiting membrane (ELM)/ellipsoid zone (EZ) restoration, excessive gliosis and subfoveal retinal pigmented epithelium (RPE) atrophy were evaluated., Results: Average AXL was 31.45 ± 2.07 mm and mean follow-up was 47.2 ± 31.4 months. Anatomical success was reached in 7/13 eyes (54%), while 2 cases showed persisting HMMH, 2 cases had early recurrence and 2 cases late recurrence. BCVA went from 0.19 ± 0.18 to 0.22 ± 0.20 at final follow-up (p = 0.64), improving in 5/13 eyes (38%). One eye showed continuous ELM and EZ lines, while another eye showed an irregular ELM but no EZ. Post-operatively, 5 eyes (71%) developed progressive atrophy of the subfoveal RPE, while excessive gliosis was reported in 3 eyes (43%). Furthermore, one patient developed post-operative chronic macular edema-like changes in the perifoveal area., Conclusion: Autologous ILM transplantation showed controversial anatomical outcomes and and poor visual results in refractory HMMH. Moreover, progressive subfoveal patchy atrophy and excessive gliosis are possible post-operative complications., Competing Interests: Declarations.

Purpose: To propose an ultrathin biological amniotic membrane (btAM) thinner than 10 μm as the graft to treat highly myopic macular holes (MH)., Methods: This pilot study included 14 patients affected by refractory macular holes associated with high myopia. btAM was used as a bandage covering the holes. The best-corrected visual acuity (BCVA), fundus photography, and optical coherence tomography (OCT) before and after surgery were compared., Results: The mean MH size was 865.93 ± 371.72 μm and all the MHs achieved anatomical closure. The btAM located centrally and fully on MHs from fundus photography yet no obvious visual masking was complained. The average BCVA 1 month, 3, and 6 months after surgery were 0.95 ± 0.24, 0.92 ± 0.23, 0.92 ± 0.23 logMAR, respectively, improved significantly compared to pre-operative BCVA (1.24 ± 0.42 logMAR, all P < 0.05). Ten out of 14 (71.4%) exhibited 2C closure patterns (formally closed and no bare RPE) on OCT., Conclusion: The btAM thinner showed a favorable anatomical success with less risk of parafoveal atrophy or iatrogenic injuries and shortened the dissolving time., Competing Interests: Declarations.

Purpose: To identify optical coherence tomography (OCT) parameters that predict postoperative best corrected visual acuity (BCVA) and are based on recent understanding of the pathomechanism of idiopathic full thickness macular hole (iFTMH) formation and closure., Methods: A retrospective consecutive case series of patients who had macular hole (MH) surgery at our institution between 2016 and 2022 was performed. 32 eyes of 30 patients were selected with at least 12 months of follow-up, closed MH and good quality OCT at each visit. Univariate correlation analysis, multiple logistic regression with forward stepwise selection, and Akaike's Information Criterion (AIC) were used to identify the best predictors for postoperative BCVA at 6 and 12 months (M), and final (≥ 12 M) visits, and a new OCT index was created. Abilities of best models/indices to predict < 0.30 logMAR (> 20/40) BCVA were compared to macular hole index (MHI) using the area under the receiver operating curve (AU-ROC) analysis., Results: Statistical analysis revealed base diameter (B) (6 M), preoperative BCVA and B (12 M) and smaller ELM-GCL distance (A), and B (final visit) as predictors for postoperative BCVA. AU-ROC analysis indicated greatest AUC at 6 M for MHI and B (0.797, p = 0.004 and 0.836 p = 0.001, respectively) and for the new A/B index at 12 M and final visit (0.844, p = 0.002 and 0.913, p = 0.003, respectively)., Conclusion: Our study suggests that MHI and B can be useful predictors of short term BCVA while the new A/B index that incorporates OCT parameters indicating potential preoperative photoreceptor damage may be a good predictor for long term postoperative BCVA. Our findings support the theory that initial hole formation mechanisms and photoreceptor damage define visual prognosis., (© 2024. The Author(s).)

Purpose: Spontaneous closure of idiopathic full-thickness macular holes (iFTMH) has been reported regularly. However, little is known about its probability and timeline., Methods: In this retrospective study all consecutive patients who presented between August 2008 and August 2019 were screened for the presence of a macular hole and only iFTMHs were included. The primary outcome measure was the spontaneous closure of the iFTMH., Results: Of 1256 eyes with macular holes, 338 fulfilled the inclusion criteria. Spontaneous closure of the iFTMH was detected in 31 eyes (9.2%) with a median time of 44 days after diagnosis. Eyes exhibiting spontaneous closure demonstrated a higher baseline best-corrected visual-acuity (BCVA) and smaller iFTMH diameter (p < 0.0001 and p < 0.0001, respectively). The mean BCVA improved from 0.4 logMAR (SD ± 0.21) to 0.29 logMAR (SD ± 0.20) after spontaneous closure (p = 0.031). The iFTMH diameter was positively correlated with the time to spontaneous closure (Pearson-r = 0.37, p = 0.0377). Spontaneously closed iFTMHs reopened in 16% (n = 5) of cases, with a median of 136 days after closure. A logistic regression model showed the hole diameter was associated with spontaneous closure (odds-Ratio 0.97, 95%CI [0.96, 0.98]). The Kaplan-Meier-Curve revealed that approximately 25% of small-iFTMH (n = 124) and 55% of iFTMH with a diameter < 150µm (n = 48) closed spontaneously within two months., Conclusion: The established gold-standard for the treatment of iFTMHs is macular surgery. However, the potential for spontaneous closure of small iFTMHs must be acknowledged. Therefore, if surgical treatment is delayed in individual cases, close observation is recommended., (© 2024.

The surgical management of macular holes is undergoing continuous evolution, with recent focus on the utilization of platelet concentrates as a promising adjunctive intervention. Currently, they present a valid surgical approach for achieving anatomical and functional success with a non-inferiority comparably to the alternative surgical techniques. Nonetheless, the utilization of varied platelet concentrates terminologies, coupled with the lack of standardization in their preparation methodologies, engenders both lexical confusion and challenges in comparing scientific studies published up until now. In this review, we summarized the published evidence concerning the application of platelet concentrates in macular holes surgery, aiming to clarify the terminology and methodologies employed and to establish a common consensus facilitating further development and diffusion of this promising technique., (© 2024.

Purpose: This study is to investigate the relationship between long-term changes in the foveal avascular zone (FAZ) and visual function of eyes with macular hole (MH) and compare the relationship between the FAZ of MH eyes and fellow eyes., Methods: This study included 31 patients with unilateral MH who underwent vitrectomy and their fellow eyes. Best-corrected visual acuity (BCVA) and metamorphopsia were measured preoperatively and at 1, 3, 6, and 12 months postoperatively. We evaluated retinal parameters using optical coherence tomography (OCT) and the superficial FAZ using OCT angiography. The FAZ ratio was defined as follows: (preoperative FAZ area of the MH eye)/(FAZ area of the fellow eye)., Results: The preoperative FAZ area of MH eyes was 0.42 ± 0.08 mm 2 , which decreased to 0.24 ± 0.07 mm 2 1 month postoperatively (p < 0.001) and slightly increased to 0.25 ± 0.06 mm 2 12 months postoperatively (p = 1.000). The FAZ area did not differ significantly from that of fellow eyes (0.39 ± 0.06 mm 2 , p = 0.281). The FAZ area of MH eyes was not associated with visual function at any time point. The FAZ ratio showed a correlation with the preoperative, 6-month, and 12-month BCVA (r = 0.604, p < 0.001; r = 0.510, p = 0.003; and r = 0.475, p = 0.007, respectively)., Conclusions: A larger FAZ in the MH eye than that in the fellow eye is associated with poorer long-term visual acuity. The preoperative comparison of the FAZ of the MH eye with that of the fellow eye may be a biomarker for predicting long-term visual acuity., (© 2024.

Lamellar macular holes (LMHs) are a manifestation of myopic tractional maculopathy (MTM). Owing to the complex and multidirectional traction force in the elongated eyeball, the clinical features, development, evolution, and treatment algorithms of LMH in highly myopic eyes may differ from those of idiopathic LMH or MTM in general. This review aimed to specifically explore the LMHs in highly myopic eyes. Several developmental processes of LMH and their association with macular retinoschisis have been demonstrated, with the tractional component identified in all processes. Epiretinal proliferation was more prevalent and more extensive in LMHs in highly myopic eyes than in idiopathic LMHs. LMHs in highly myopic eyes may remain stable or progress to foveal detachment and full-thickness macular hole with or without retinal detachment. The predictive factors associated with disease progression were summarized to facilitate monitoring and guide surgical intervention. The treatment of LMHs in highly myopic eyes was based on an algorithm for treating myopic tractional maculopathy, including gas tamponade, pars plana vitrectomy, macular buckling, and a combination of vitrectomy and macular buckling. New internal limiting membrane (ILM) manipulation techniques such as fovea-sparing ILM peeling or fovea-sparing ILM peeling combined with ILM flap insertion could reduce the risk of developing iatrogenic full-thickness macular holes postoperatively. Further research should focus on the treatment of LMH in highly myopic eyes., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Purpose: To elucidate the clinical features and surgical outcomes of full-thickness macular hole (FTMH) with epiretinal proliferation (EP) diagnosed by both en-face and B-mode optical coherence tomography (OCT)., Method: This retrospective cohort study classified idiopathic FTMHs into two groups, based on B-scan and en-face OCT imaging: FTMH with EP (EP group) and without EP (non-EP group). The preoperative features, as well as postoperative outcomes up to 12 months, were compared between the two groups., Result: Among 318 eyes of idiopathic FTMH that met the inclusion criteria, 59 eyes (18.6%) were in the EP group, and others were in the non-EP group. In 9 eyes (15.3%) out of the EP group, EP was not detected in the preoperative B-mode OCT but was identified through the en-face OCT. Baseline features showed a higher male proportion (47.5% vs. 27.8%, P = 0.005) and a lower incidence of vitreofoveal traction (P < 0.001) in the EP group than in the non-EP group. The EP group showed worse visual recovery than the non-EP group (- 0.23 vs. - 0.41 logarithm of the minimum angle of the resolution at 12 months, P = 0.001)., Conclusion: The en-face OCT enhances diagnostic accuracy of EP in FTMH eyes, especially in the case with smaller extent of EP. Eyes with FTMH with EP showed a worse visual recovery than FTMH without EP., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Purpose: To test the hypothesis that optical coherence tomography (OCT) choroidal hypertransmission width (CHW) is a prognostic biomarker in idiopathic macular hole (MH) surgery METHODS: Retrospective cohort study of consecutive patients undergoing successful pars plana vitrectomy for idiopathic MH. We collected demographic, clinical, and OCT variables at the preoperative and last available visits. Two investigators assessed the following OCT parameters: MH minimum diameter, base diameter, CHW, ellipsoid zone, and external limiting membrane status (absent vs. present). Delta CHW was calculated as the difference between CHW and MH minimum diameter. Linear models were used to investigate factors associated with postoperative best-corrected visual acuity (BCVA) and BCVA change., Results: Thirty-six eyes (36 patients) with a median (interquartile range (IQR)) follow-up of 9 (8-11) months were included. The median BCVA (IQR) improved from 0.75 (1-0.6) logMAR preoperatively to 0.2 (0.6-0.1) logMAR at the last visit (p < 0.001). Preoperative MH minimum diameter (for a 10-μm increase, estimate (standard error (SE)): 0.009 (0.003) logMAR, p = 0.003), base diameter (for a 10-μm increase, 0.003 (0.001) logMAR, p = 0.032), CHW (for a 10-μm increase, 0.008 (0.002) logMAR, p < 0.001), and delta CHW (for a 10-μm increase, 0.013 (0.005) logMAR, p = 0.009) were significantly associated with postoperative BCVA. The proportion of variance explained was the highest for MH CHW (R 2 0.35), followed by minimum MH diameter (R 2 0.24), delta CHW (R 2 0.19), and MH base diameter (R 2 0.14). None of the study variables was associated with delta BCVA., Conclusion: Preoperative CHW is associated with postoperative visual acuity in patients undergoing successful idiopathic MH surgery and may be a useful OCT prognostic biomarker., (© 2024.

Purpose: To report the characteristics and the visual and anatomical outcomes of secondary macular holes (SMHs) diagnosed after rhegmatogenous retinal detachment (RRD) repair and their associated factors., Methods: Retrospective, interventional case series. All consecutive patients who were diagnosed with SMH after RRD repair at Beijing Tongren eye center from January 2016 to April 2021 were included. Patients who had their primary RRD repair in other hospitals and were referred to our center after diagnosis of SMH were also included. The minimum follow-up time after RRD repair was 6 months., Results: 37 SMHs were diagnosed within a series of 5696 RRDs. Including 24 eyes referred from other hospitals after the diagnosis of SMH, 61 eyes were included. The type of primary RRD repair surgery included 22/61 (36%) eyes with scleral buckling procedure (SBP) and 39/61 (64%) eyes with pars plana vitrectomy (PPV). 21/61 (34%) eyes had recurrent RD. The median time to SMH diagnosis was 150 days (range, 7 ~ 4380 days). Macular hole (MH) closure was achieved in 77% eyes. Visual acuity (VA) improvement of at least 2 lines of Snellen's visual acuity was observed in 51% eyes. Final MH closure status was associated with preoperative MH diameter (for every 50 μm increment) (P = 0.046, OR = 0.875, 95%CI: 0.767 ~ 0.998). VA improvement was associated with final MH closure status (P = 0.009, OR = 8.742, 95%CI: 1.711 ~ 44.672). Final VA (logMAR) was associated with recurrent RD (P < 0.001, B = 0.663, 95%CI: 0.390 ~ 0.935), preoperative MH diameter (P = 0.001, B = 0.038, 95%CI: 0.017 ~ 0.058), VA at the time of SMH diagnosis (P < 0.001, B = 0.783, 95%CI: 0.557 ~ 1.009) and final MH closure status (P = 0.024, B = -0.345, 95%CI: -0.644 ~ -0.046). For patients without recurrent RD, VA improvement and final VA was associated with final MH closure status (P = 0.016 and P < 0.001, respectively), while for patients with recurrent RD, VA improvement or final VA did not associate with final MH closure status (P > 0.05)., Conclusion: For SMH diagnosed after RRD repair, final MH closure status was associated with preoperative MH diameter. Recurrent RD, larger preoperative MH diameter, worse VA at the time of SMH diagnosis and failed MH closure are predictive factors for worse final VA. Visual outcome is associated with final MH closure status in patients without recurrent RD, but not as so in patients with recurrent RD., (© 2023.

Purpose: To report outcomes of re-vitrectomy using light silicone oil (SO) tamponade for persistent macular holes (MHs)., Methods: We reviewed cases of patients with full-thickness MHs that underwent pars plana vitrectomy (PPV) with air/gas and were re-vitrectomized using light SO tamponade after primary non-closure (persistent MHs). Outcome measures included anatomic closure rates and patterns confirmed by optical coherence tomography (OCT) and changes in best-corrected visual acuity (BCVA)., Results: A total of 42 eyes of 41 patients with unsuccessful primary PPV with air/gas were included. After re-vitrectomy with light SO (1000-centistoke), 29 (69%) eyes demonstrated type 1 closure without neurosensory defects in OCT scans, whereas 9 eyes (21%) showed type 2 closure with persisting neurosensory defects. Available data (n = 21) showed a significant mean improvement of BCVA from 0.99 logMAR (SD 0.25, range 0.7-1.3) preoperatively to 0.74 logMAR (SD 0.42, range 0.2-1.5) postoperatively (p = 0.035)., Conclusion: The treatment of persistent MHs with PPV and light SO tamponade resulted in high closure rates., (© 2023.

Purpose: To propose a novel technique of an internal limiting membrane (ILM) flap using ophthalmic viscoelastic device (OVD) with no requirement for postoperative head posture for the treatment of lamellar macular hole (LMH) repair., Methods: A retrospective analysis of 16 consecutive eyes of LMH patients who underwent vitrectomy with ILM flap with OVD. Best-corrected visual acuity (BCVA), central macular thickness (CMT), simultaneous cataract extraction, and ellipsoid zone disruption preoperatively and at the final follow-up were compared., Results: The mean age was 73.19 ± 7.26 years, and ten patients (62%) were females. The mean follow-up was 5.06±1.43 months (range 3-6). For all patients, BCVA was significantly improved at the final visit, from 0.65±0.36 logMAR units to 0.42±0.29 (p < 0.001). None of the patients had visual loss. Six patients had epiretinal membrane (ERM) foveoschisis, and the rest had LMH with epiretinal proliferation. Both subgroups presented a significant improvement in their BCVA with a trend for better improvement in the latter (p=0.09). Ellipsoid zone disruption was seen in 7 patients including one patient with a macular scar. There was no significant effect of ellipsoid zone disruption on the final BCVA (p=0.33). Twelve eyes (75%) underwent simultaneous cataract extraction. Mean BCVA at the final postoperative visit improved regardless of whether the eyes underwent simultaneous cataract surgery (p=0.39). CMT was also significantly improved at the final visit, from 200.06±46.8 μm preoperatively to 305.00±85.5 μm (p<0.001). No full-thickness macular holes were developed postoperatively. No intraoperative or postoperative complications were observed., Conclusions: Treatment of LMH with ILM flap with OVD showed promising anatomical and functional results with no postoperative head position requirements., (© 2023.

Purpose: The aim of this study was to assess the efficacy and safety of a novel releasing-closing-tapping approach in the treatment of persistent macular holes (PMHs) after initial surgery with internal limiting membrane (ILM) peeling., Methods: We retrospectively analyzed patients with PMHs after initial surgery with ILM peeling who were treated with a novel releasing-closing-tapping approach. After repeated pars plana vitrectomy (PPV), the surgeon effectively released the adhesion between the edges and retinal pigment epithelium (RPE) by gently scraping the retinal neuroepithelium. Then, the hole was converted into a transverse slit, and the edges were gently tapped flat so that they attached to the RPE, and no space was left under the edges. Finally, air tamponade was carried out. The primary outcome measures included MH closure and the change in best-corrected visual acuity (BCVA) from preoperatively to postoperatively., Results: The study included 11 PMH patients with a mean age of 63.82 ± 3.31 years. The mean minimum linear diameter of PMHs was 666.3 ± 208.1 μm, and the mean basal diameter was 1547.2 ± 351.8 μm. MH closure was achieved in 90.9% (10/11) of eyes, with significant improvement of visual acuity from 1.19 ± 0.30 logMAR to 0.65 ± 0.29 logMAR postoperatively., Conclusion: The releasing-closing-tapping approach with repeated PPV is a simple, effective, and safe surgical procedure for refractory PMHs after initial surgery with ILM peeling that can significantly improve the visual outcome and achieve a high surgical success rate., (© 2023.

Purpose: The aim of this study was to analyze the anatomical choroidal vascular layers and the changes in idiopathic macular hole (IMH) eyes over time after vitrectomy., Methods: This is a retrospective observational case-control study. Fifteen eyes from 15 patients who received vitrectomy for IMH and age-matched 15 eyes from 15 healthy controls were enrolled in this study. Retinal and choroidal structures were quantitatively analyzed before vitrectomy and 1 and 2 months after surgery using spectral domain-optical coherence tomography. Each choroidal vascular layer was divided into the choriocapillaris, Sattler's layer, and Haller's layer, and then, the choroidal area (CA), luminal area (LA), stromal area (SA), and central choroidal thickness (CCT) were calculated using binarization techniques. The ratio of LA to CA was defined as the L/C ratio., Results: The CA, LA, and L/C ratios were 36.9 ± 6.2, 23.4 ± 5.0, and 63.1 ± 7.2 in the choriocapillaris of IMH and were 47.3 ± 6.6, 38.3 ± 5.6, and 80.9 ± 4.1 in that of control eyes, respectively. Those values were significantly lower in IMH eyes than in control eyes (each P < 0.01), whereas there was no significant difference in total choroid, Sattler's layer, and Haller's layer or CCT. The ellipsoid zone defect length showed a significant negative correlation with the L/C ratio in total choroid and with CA and LA in the choriocapillaris of IMH (R =  - 0.61, P < 0.05, R =  - 0.77, P < 0.01, and R =  - 0.71, P < 0.01, respectively). In the choriocapillaris, the LA were 23.4 ± 5.0, 27.7 ± 3.8, and 30.9 ± 4.4, and the L/C ratios were 63.1 ± 7.2, 74.3 ± 6.4, and 76.6 ± 5.4 at baseline, 1 month, and 2 months after vitrectomy, respectively. Those values showed a significant increase over time after surgery (each P < 0.05), whereas the other choroidal layers did not alter consistently with respect to changes in choroidal structure., Conclusions: The current OCT-based study demonstrated that the choriocapillaris was exclusively disrupted between choroidal vascular structures in IMH, which may correlate with the ellipsoid zone defect. Furthermore, the L/C ratio of choriocapillaris recovered after IMH repair, suggesting an improved balance between supply and demand of oxygen that has collapsed due to temporary loss of central retinal function by IMH., (© 2023.

Background: Stickler syndrome (STL) is an inherited progressive connective tissue collagen disorder. STL is the most common hereditary cause of retinal complications, retinal tears, and the development of retinal detachment (RD) in childhood. The aim of the study was to evaluate the long-term anatomical and functional results of surgical treatment of retinal complications in children and adolescents affected by STL., Methods: A retrospective, single-center study was performed a cohort of children with STL who underwent retinal surgery between 2004 and 2021., Results: The study group consisted of nine children; the mean age at the time of the retinal tear with/without retinal detachment was 7.2 (2-10) years, and the mean follow-up period was 9.6 (5-16) years. Pathogenic variants COL2A1 (5 children) and COL11A1 (3 children) were confirmed in our cohort. In total, we operated on 13 eyes, 11 eyes with complicated RD and two eyes with multiple retinal defects, but without RD. At the end of the follow-up period, an attached retina was achieved 77% (10 eyes) with or without silicone oil tamponade: cryopexy alone was successful in one eye (10%), scleral buckling (EB) in five eyes (50%), and vitrectomy with silicone oil tamponade combined with EB in four eyes (40%). The mean number of surgeries was 2.3 per eye. The resulting best corrected visual acuity ranged from 0.03 to 0.1 in one eye, from 0.16 to 0.4 in two eyes, and from 0.5 to 1.0 in 7 eyes., Conclusion: Repair of retinal tears with/without retinal detachment in patients with Stickler syndrome often requires multiple surgeries with combinations of cryopexy, scleral buckling, and/or vitrectomy with silicone oil tamponade. Treatment of the ocular complications arising from STL requires long-term comprehensive care., (© 2023.

Purpose: To assess study design and a range of anatomical and functional changes after internal limiting membrane (ILM) peeling using forceps developed for atraumatic ILM pick-up compared to standard forceps., Methods: We conducted a masked proof-of concept randomised controlled trial (RCT) on 65 patients who underwent ILM peeling for idiopathic full-thickness macular hole (FTMH) using etched-tip forceps (etched-tip group, 33 eyes) compared to standard ILM forceps (smooth-tip group, 32 eyes). Patients were assessed preoperatively, 3 weeks, 3 and 6 months postoperatively., Results: The primary closure rate was 95.4%. There was no statistically significant difference between the groups in terms of final visual acuity (66.9 vs 70.9 ETDRS letters, p = 0.13), difference of visual field mean deviation (1.32 vs 1.14 decibels), and number of eyes with pick-up-related retinal haemorrhages (16% vs 16%, p = 0.96), swelling of arcuate nerve fibre layer lesions (63% vs 55%, p = 0.54), number of dissociated optic nerve fibre layer lesions (31.4 vs 41.0, p = 0.16), nor inner retina defects (37% vs 22%, p = 0.17). Similar changes in inner retinal volumes were detected in all 9 sectors of an ETDRS grid except for a trend (p = 0.06) towards a lower reduction in the inferior inner sector in the etched-tip group., Conclusions: The study was successfully completed with masking maintained and a low risk of bias. Multiple endpoints relating to ILM peeling were assessed, and estimates were provided that can be used for future studies. Although the study was not powered to assess any specific endpoint, the anatomical and functional outcomes assessed did not significantly differ., (© 2022. The Author(s).)

Purpose: The purpose is to assess the effect of ethnicity on surgical macular hole closure., Methods: A retrospective cohort study was undertaken in five UK National Health Service Hospitals. We included all patients with known ethnicity undergoing vitrectomy, internal limiting membrane peel, and gas/oil tamponade for all stages of primary full-thickness macular hole (FTMH). The primary outcome was anatomic success, defined as FTMH closure with one operation. The secondary outcome was mean change in best-corrected visual acuity (BCVA) comparing baseline with final review., Results: Of 334 operations, the ethnicity profile comprised 78.7% White patients, 11.7% Black patients, 8.1% Asian patients, and 1.5% in mixed/other ethnicities. Mean age was 69.7 years with 68.5% females. Overall, 280 (83.8%) had anatomic success. Anatomic failure occurred in 38.5% of Black patients versus 12.6% of White patients (relative risk: 1.788; 95% CI: 1.012 to 3.159; P = 0.045). Overall, baseline logarithm of the minimum angle of resolution BCVA improved by 0.34, from 0.95 (95% CI: 0.894 to 1.008) to 0.62 (95% CI: 0.556 to 0.676). Mean BCVA improved by 0.35 in White patients, 0.37 in Black patients, 0.23 in Asian patients, and 0.38 in mixed/other ethnicity (P = 0.689). Greater FTMH minimum linear diameter was associated with an increased risk of anatomic failure (relative risk: 1.004; 95% CI: 1.002 to 1.005; P < 0.0001), whereas better pre-operative BCVA (F [1,19] = 162.90; P < 0.0001) and anatomic success (F [1,19] = 97.69; P < 0.0001) were associated with greater BCVA improvement. Socio-economic status did not significantly influence anatomic success or BCVA change., Conclusions: Black ethnicity is associated with an approximately twofold greater risk of failed FTMH surgery. The reasons for this difference warrant further study., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Purpose: To compare the three-dimensional (3D) heads-up surgery with the traditional microscopic (TM) surgery for various vitreoretinal diseases., Methods: A medical record review of patients that underwent 3D heads-up or TM vitreoretinal surgeries was performed from May 2020 to October 2021 in this retrospective case-control study. Main outcome measures included surgery-related characteristics, efficacy, safety, and satisfaction feedback from the surgical team., Results: A total of 220 (47.6%) and 242 (52.4%) eyes were included in the 3D and TM groups, respectively. The 3D heads-up system significantly benefits delicate surgical steps, like the epiretinal membrane (ERM) peeling for ERM and internal limiting membrane peeling for idiopathic macular holes (P < 0.05). The 3D heads-up system could facilitate a significantly better visual outcome for pathologic myopic foveoschisis (P = 0.049), while no difference by TM surgery (P = 0.45). For the satisfaction feedback, the 3D heads-up system was rated significantly higher in most subscales and the overall score (P < 0.05). The surgeons' ratings on operating accuracy and the first assistants' rating on operating accuracy and operation cooperation were significantly higher in the TM group than in the 3D group (P < 0.05). Besides that, the 3D heads-up surgery was comparable with TM surgery in the surgery-related characteristics, choice of tamponades, postoperative VA, primary anatomic success, and perioperative complications (P > 0.05)., Conclusion: The efficacy and safety of the 3D heads-up surgery were generally comparable to the TM surgery. The 3D heads-up system could significantly benefit delicate surgical steps and achieve better surgical team satisfaction., (© 2022. The Author(s).)

Purpose: To evaluate the surgical management, outcomes and prognostic factors of full thickness macular holes without residual internal limiting membrane (NO-ILM FTMHs)., Methods: We performed a multicenter, retrospective study of 116 NO-ILM FTMHs. Human amniotic membrane (hAM) plug, autologous ILM free flap transplantation (AILMT), and autologous retinal graft transplantation (ART) were performed in 58, 48, and 10 patients, respectively. Data were collected before and up to 12 months after surgery. The primary outcomes were hole closure and final best-corrected visual acuity (BCVA)., Results: The final BCVA (0.78 ± 0.51 logMAR) was significantly better than and correlated with the initial BCVA (p < 0.0001 and p = 0.004, respectively). Hole closure was achieved in 92% of eyes. The minimum FTMH diameter was wider and final BCVA was lower in the ART group than in the other groups (p < 0.003 and p < 0.001, respectively). FTMHs with diameter > 680 μm had a higher closure rate with hAM than with AILMT (p = 0.02)., Conclusions: AILMT and hAM were the most frequently performed surgeries with both high closure rate and significant functional improvement. Preoperative BCVA was correlated with final BCVA. The minimum FTMH diameter may guide the treatment choice., (© 2022. The Author(s).)

Purpose: This study aims to compare the improvement of best-corrected visual acuity (BCVA) and the reduction in defect length of external limiting membrane (ELM) and ellipsoid zone (EZ) in small ([Formula: see text] 250 μm), medium ([Formula: see text] 250 μm), and large ([Formula: see text] 400 μm) full-thickness macular holes (FTMH) treated with inverted internal limiting membrane (I-ILM) flap technique over a follow-up period of 12 months., Methods: Ninety-one eyes of 87 patients were enrolled in this retrospective study. BCVA and spectral-domain optical coherence tomography (SD-OCT) were conducted preoperatively as well as after 1, 3, 6, 9, and 12 months postoperatively. The defect length of the ELM and the EZ was measured using the caliper tool at each follow-up time point., Results: BCVA improved significantly in the group of small, medium, and large FTMH over the time of 12 months, whereby the improvement did not depend on FTMH size over 9 months. Only after 12 months, large FTMH showed significantly higher BCVA improvement compared to small and medium FTMH. The closure rate was 100% (91/91). The defect length of ELM and EZ reduced continuously over the period of 12 months. There was a significant correlation between defect length of ELM and EZ with postoperative BCVA., Conclusion: The I-ILM flap technique has very good morphological and functional outcomes in small, medium, and large FTMH over a long-time period, indicating that it can be considered as a treatment option in small and medium FTMH. The defect length of ELM and EZ is directly connected to postoperative BCVA., (© 2022. The Author(s).)

Purpose: To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH)., Methods: By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS)., Results: The healing (mean±standard deviation in months) most involved fusion at the level of the outer nuclear layer (ONL) (6.3±10.5) followed by restoration of ELM (9.1±13.8), and lastly, by IS/OS regeneration (13.1±19.5). In severe blunt ocular trauma, healing was fast and involved subretinal zipper glue-like reapposition with resulting outer retinal atrophy. Best spectacle-corrected visual acuity correlated with normalization of the clivus (p=0.012), faster ELM (p=0.006), and IS/OS reconstitution (p=0.024). Recurrence of FTMH occurred when the healing was halted (3 eyes) or was aberrant by lamellar hole epiretinal proliferation (LHEP) (3 eyes) or by the persistence of VMT (1 eye)., Conclusion: Recovery sequences proceeded from the ONL to the deeper layers with BCVA correlating absolutely and temporally with the restoration of outer retinal layer integrity., (© 2022.

Purpose: To assess the closure rate of large full-thickness macular holes (FTMH) associated with epiretinal membrane (ERM) with a combined epiretinal and internal limiting membrane retracting door flap., Methods: Retrospective chart review of patients treated at a single tertiary retina practice between January 2017 and November 2019. Individuals with FTMH larger than 400 μm and co-diagnosis of ERM who underwent surgical repair with an ERM flap were included. Patients underwent pars plana vitrectomy with peeling of ERM that was positioned as a retracting door flap to cover the FTMH. Primary outcome was closure rate at 6 months following surgery. Final surgical success rate and visual acuity were secondary outcomes., Results: Among 7 eyes of 7 patients, 6 eyes achieved primary surgical success and final surgical success rate was achieved in all 7 eyes with a large FTMH repaired with ERM flap. The mean minimum linear diameter of the FTMH was 681 μm ± 295. All patients had follow-up greater than 6 months, with a mean duration of 17 months (range 14-23 months). Visual acuity improved from a mean of 0.9 ± 0.3 logMar (20/160) before surgery to 0.3 ± 0.5 logMar (Snellen 20/40), postoperatively., Conclusion: Large FTMH with concurrent ERM that are managed with an ERM flap have high single-surgery success rate., (© 2022.

Purpose: To compare the surgical outcomes of epiretinal membranes (ERMs) associated with retinal break and idiopathic ERMs., Methods: This retrospective study included patients with an idiopathic ERM or an ERM associated with retinal break, who were followed up for ≥ 6 months after ERM removal. The postoperative functional and anatomical outcomes were compared between the groups., Results: A total of 160 and 38 eyes (198 patients) were in the idiopathic and retinal break groups, respectively. There was no significant difference in the baseline anatomical and functional parameters between the groups. At 6 months after surgery and at the final follow-up, best-corrected visual acuity, central foveal thickness, and ectopic inner foveal layer improved significantly in both groups, but there was no significant difference between the groups. In latter 49.0% of patients, tests for metamorphopsia and aniseikonia were performed. There was a significant improvement in the scores of metamorphopsia (0.40 ± 0.38 to 0.27 ± 0.28; p < 0.001) and aniseikonia (6.07 ± 4.46 to 4.11 ± 3.52; p < 0.001) in the idiopathic group at 6 months after surgery, but not in the retinal break group. The idiopathic group had significantly greater circularity of ERM extent compared to the retinal break group (p = 0.025)., Conclusion: Visual and anatomical improvements after removal of ERMs associated with retinal break and idiopathic ERMs were comparable. However, metamorphopsia and aniseikonia improved only after removal of idiopathic ERMs., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Purpose: To evaluate the outcome of pneumatic vitreolysis (PVL) for vitreomacular traction (VMT) with or without full thickness macular hole (MH) < 400 µm., Methods: Forty-seven eyes of 47 patients were included who had undergone PVL for VMT with or without MH. Main outcome measures were release of VMT, MH closure, best-corrected visual acuity (BCVA) and adverse events., Results: Thirty-three patients had isolated VMT and 14 patients VMT with a MH. Four weeks after PVL, the overall VMT release rate was 35/47 (74.5%): 25/37 (67.6%) in phakic and 10/10 (100%) in pseudophakic eyes (p = 0.03). Four of 14 MH (28.6%) were closed. Twenty-two of 47 (46.8%) eyes required a subsequent PPV: 12/33 (36.4%) in the VMT only group and 10/14 (71.4%) in the VMT with MH group. Mean BCVA improved from 0.48 (± 0.24) to 0.34 (± 0.23) logMAR at 6 months in patients with VMT alone (p < 0.001), and from 0.57 (± 0.27) to 0.41 (± 0.28) logMAR in patients with VMT and MH (p = 0.008). Adverse events included new formation of a large MH in 4/33 (12.1%) eyes, failure of MH closure in 10/14 (71.4%) eyes, progression of mean minimum linear diameter (MLD) MH size from baseline 139 (± 67) to 396 (± 130) µm (p < 0.001) and development of a retinal detachment in 4/47 (8.5%) eyes., Conclusion: While PVL leads to a high VMT release rate particularly in pseudophakic eyes, it is associated with a relatively high incidence of MH formation, MH size progression and retinal detachment., (© 2022.

Objective: We conducted a systematic review to evaluate the outcome of macular hole (MH) treatment in eyes with uveitis., Data Source: We searched PubMed and Embase databases from inception through August 15, 2021., Study Selection: We included eyes with MHs secondary to uveitis that were managed medically or underwent pars plana vitrectomy (PPV). We excluded eyes with idiopathic MH and those secondary to causes other than uveitis., Results: Of 27 articles, we identified 86 eyes with MH secondary to uveitis that received either conservative medical treatment alone or PPV with adequate follow-up. The mean (± SD) age of patients included in this review was 46.6 (± 16.8) years; 60.5% were males. The most common etiology of uveitis was Behçet's disease (34.6%) and toxoplasmosis (19.7%). The most common anatomical location of uveitis was posterior (59.3%) followed by panuveitis (35.2%). The mean (± SD) baseline LogMAR vision was 1.1 (± 0.5). Conservative medical treatment was employed in 34.9%, while PPV was performed in 65.1% of eyes. Overall, the mean (SD) LogMAR vision improved from 1.1 (± 0.5) at baseline to 0.7 (± 0.5) after treatment. Inflammation-related MHs were closed in 40% of eyes after conservative therapy and in 87.5% of eyes after PPV. Visual improvement occurred in most eyes (83.9%) that had successful closure of their MH., Conclusions: Visual improvement occurs in most eyes that had successful closure of their inflammation-related MH. Conservative medical control of uveitis may lead to closure of inflammation-related MHs and is an important step prior to surgery, if required. Surgical intervention for inflammation-related MHs is associated with good functional and anatomical results., (© 2022.

Purpose: To study the functional and morphological results of the inverted internal limiting membrane (ILM) flap technique for the treatment of idiopathic macular holes (MHs) sized ≤ 250 µm, > 250 and ≤ 400 µm, and > 400 µm., Methods: Retrospective, nonrandomized interventional study of 65 eyes with primary idiopathic MHs who underwent pars plana vitrectomy (PPV) with the inverted ILM flap technique. Closure rate, best-corrected visual acuity (BCVA), and integrity of external limiting membrane (ELM) and ellipsoid zone (EZ) were analyzed by optical coherence tomography (OCT)., Results: Total closure rate was 96.9% with 100% in the ≤ 250 µm group, 100% in the > 250 and ≤ 400 µm group, and 91.7% in the > 400 µm group. Mean BCVA significantly improved after treatment: from 0.7 to 0.3 LogMAR in the ≤ 250 µm group (n = 15, p < 0.001), from 0.9 to 0.4 LogMAR in the > 250 and ≤ 400 µm group (n = 26, p < 0.001), and from 1.0 to 0.5 LogMAR in the > 400 µm group (n = 24, p < 0.001). A total of 16 patients had follow-up over 14 months: BCVA increased from 0.9 LogMAR preoperatively to 0.4 after 1 month (p < 0.00001) and to 0.3 LogMAR after 14 months (p = 0.03). A recovered ELM could be observed in 56.3% after 1 month and in 87.5% after 14 months. A recovered EZ could be observed in 18.8% after 1 month and in 68.8% after 14 months., Conclusion: The study demonstrates a high closure rate with corresponding restitution of outer retinal layers. In addition to its importance for the treatment of MHs > 400 µm, the inverted ILM flap technique also appears to be effective and safe for the treatment of MHs < 400 µm., Trial Registration: WHO: DRKS00021241., (© 2022.

Background: Due to intraoperative optical coherence tomography (iOCT), observation of retinal morphological changes during surgery has become possible., Objective: To analyze the intraoperative morphology of full thickness macular holes (FTMH) and the correlation with the postoperative function, a retrospective, observational clinical study was performed analyzing 32 eyes of patients treated at the hospital of the technical university of Munich., Material and Methods: Using iOCT in 32 eyes of 32 consecutive patients, the operative morphology was analyzed during surgery. These findings were then correlated with the postoperative visual outcome., Results: After posterior vitreous detachment (PVD) the macular hole index (MHI) decreased by -0.05 (p = 0.01) and the base diameter (BD) increased by +99.4 μm (SD = 197.8 μm; p = 0.04). Closure rate was 100% at the first visit after a mean time of 73 days and the postoperative best corrected visual acuity (BCVA) significantly improved (p < 0.05). There were significant correlations between intraoperative morphology and postoperative results indicating a relation between low MHI and better postoperative BCVA (SCC = 0.50; p = 0.02), large BD and better postoperative BCVA (SCC = 0.43; p = 0.05) and large aperture after PVD and higher improvement of BCVA (SCC = 0.44; p = 0.03)., Conclusion: Flattening and broadening of the FTMH occurred as a result of reduction of vitreoretinal traction. The significant correlation between a large operative BD and improved BCVA reveals the importance of intraoperative retinal relaxation., (© 2021. The Author(s).)

Purpose: To evaluate the use of highly concentrated autologous platelet-rich plasma (PRP) in lamellar macular hole (LMH) surgery with regard to function and morphology., Methods: We included 12 eyes of 12 patients with progressive LMH in this interventional case series. After 23/25-gauge pars plana vitrectomy, 0.1ml highly concentrated autologous platelet-rich plasma was applied under air tamponade. Induction of posterior vitreous detachment and peeling of tractive epiretinal membranes were performed whenever present. Phacovitrectomy was undertaken in cases of phakic lens status. Postoperatively, all patients were instructed to rest in a supine position for the first two postoperative hours. Best-corrected visual acuity (BCVA) testing, microperimetry, spectral-domain optical coherence tomography (SD-OCT), and fundus photography were carried out preoperatively and 6 months postoperatively., Results: Foveal configuration was restored in 10 of 12 patients (83.3%) at 6 months postoperatively. Two patients who had not undergone ILM peeling showed a recurring defect at 6-month follow-up. Best-corrected visual acuity improved significantly from 0.29 ± 0.08 to 0.14 ± 0.13 logMAR (Wilcoxon: p=0.028). Microperimetry remained unchanged (23.38 ± 2.53 preoperatively; 23.0 ± 2.49 dB postoperatively; p=0.67). No patient experienced vision loss after surgery, and no significant intra- or postoperative complications occurred., Conclusion: The application of PRP in the surgical therapy of LMH results in good morphological and functional outcomes. Additional peeling of the ILM seems to be mandatory when using PRP to prevent the recurrence of LMH. Strict postoperative supine positioning for 2 h avoids PRP dislocation. Larger sample sizes are needed to confirm the results., (© 2021. The Author(s).)

Purpose: To create a model for prediction of postoperative visual acuity (VA) after vitrectomy for macular hole (MH) treatment using preoperative optical coherence tomography (OCT) images, using deep learning (DL)-based artificial intelligence., Methods: This was a retrospective single-center study. We evaluated 259 eyes that underwent vitrectomy for MHs. We divided the eyes into four groups, based on their 6-month postoperative Snellen VA values: (A) ≥ 20/20; (B) 20/25-20/32; (C) 20/32-20/63; and (D) ≤ 20/100. Training data were randomly selected, comprising 20 eyes in each group. Test data were also randomly selected, comprising 52 total eyes in the same proportions as those of each group in the total database. Preoperative OCT images with corresponding postoperative VA values were used to train the original DL network. The final prediction of postoperative VA was subjected to regression analysis based on inferences made with DL network output. We created a model for predicting postoperative VA from preoperative VA, MH size, and age using multivariate linear regression. Precision values were determined, and correlation coefficients between predicted and actual postoperative VA values were calculated in two models., Results: The DL and multivariate models had precision values of 46% and 40%, respectively. The predicted postoperative VA values on the basis of DL and on preoperative VA and MH size were correlated with actual postoperative VA at 6 months postoperatively (P < .0001 and P < .0001, r = .62 and r = .55, respectively)., Conclusion: Postoperative VA after MH treatment could be predicted via DL using preoperative OCT images with greater accuracy than multivariate linear regression using preoperative VA, MH size, and age., (© 2021.

Pneumatic retinopexy (PR) is a minimally invasive, non-incisional procedure for repairing uncomplicated rhegmatogenous retinal detachment. It consists of an intravitreal gas injection followed by the maintenance of a postoperative head position and the use of laser or cryopexy to seal the retinal breaks. It was initially indicated for a single or a group of retinal breaks no larger than 1 clock hour involving the superior 8 clock hours in phakic eyes with no proliferative vitreoretinopathy. We aim to perform a narrative review on pneumatic retinopexy since the last major review of 2008, based on a Medline search up to June 20 2021 using multiple search words including pneumatic retinopexy, pneumoretinopexy, retinal detachment, and pars plana vitrectomy. Indications for PR have been expanded and include pseudophakic eyes, eyes with mild PVR, and even breaks in the inferior fundus. Depending on the case selection, PR has a single-operation success rate ranging from 45 to 80%. Despite the lower single operation success rate, the functional outcomes of those eyes repaired successfully by primary PR exceed those of scleral buckling (SB) and pars plana vitrectomy (PPV). Best corrected visual acuity, metamorphopsia scores, mental health scores, and vision-related functioning scores were all better in PR-treated eyes compared to PPV-treated eyes. PR should be strongly considered for eligible patients with a primary uncomplicated rhegmatogenous retinal detachments., (© 2021.

Purpose: To describe characteristics of the vitreomacular interface (VMI) in traumatic macular holes (TMH) compared to idiopathic macular holes (IMH) using immunofluorescence and electron microscopy, and to correlate with clinical data., Methods: For immunocytochemical and ultrastructural analyses, premacular tissue with internal limiting membrane (ILM) and epiretinal membrane (ERM) was harvested during vitrectomy from 5 eyes with TMH and 5 eyes with IMH. All specimens were processed as flat mounts for phase-contrast microscopy, interference and fluorescence microscopy, and transmission electron microscopy (TEM). Primary antibodies were used against microglial and macroglial cells. Clinical data was retrospectively evaluated., Results: Surgically excised premacular tissue of eyes with TMH showed a less pronounced positive immunoreactivity for anti-glutamine synthetase, anti-vimentin and anti-IBA1 compared to eyes with IMH. Cell nuclei staining of the flat-mounted specimens as well as TEM presented a lower cell count in eyes with TMH compared to IMH. All detected cells were found on the vitreal side of the ILM. No collagen fibrils were seen in specimens of TMH. According to patients' age, intraoperative data as well as spectral-domain optical coherence tomography (SD-OCT) analysis revealed an attached posterior vitreous in the majority of TMH cases (60%), whereas all eyes with IMH presented posterior vitreous detachment., Conclusion: The vitreomacular interface in TMH and IMH shows significant differences. In TMH, glial cells are a rare finding on the vitreal side of the ILM., (© 2021. The Author(s).)

Background: To present the anatomical and functional outcomes of combined fovea-sparing internal limiting membrane peeling (FSIP) with internal limiting membrane flap (ILMF) for myopic traction maculopathy (MTM)., Methods: This is a retrospective, observational study. Included were 66 eyes of 62 patients who underwent vitrectomy with combined FSIP and ILMF (or modified ILMF) for MTM with a minimal follow-up of 6 months. Thirty-one eyes were treated with FSIP, and 35 with modified ILMF., Results: The post-operative best-corrected visual acuity (BCVA) improved from 20/148 to 20/87 in the FSIP group (p < 0.001), and from 20/121 to 20/66 in the modified ILMF group (p < 0.001). The post-operative macular thickness (MT) reduced after FSIP (from 739.58 to 223.81 μm, p < 0.001) and modified ILMF (from 706.43 to 236.59 μm, p < .001). The degree of the improvement of BCVA and MT in both groups was insignificant. The incidence of a post-operative macular hole (MH) was 9.7% (3/31 eyes) with FSIP and 0% (0/35 eyes) with modified ILMF. All patients with a MH had foveoschisis in association with a lamellar hole (LMH) pre-operatively. After controlling the surgical technique, pre- and post-operative MT, follow-up duration, myopic atrophy maculopathy, and FD, the surgical technique showed significant effects on post-operative MH in all cases (p = 0.022) and in those with pre-operative LMH (p = 0.029)., Conclusion: Our pilot study showed both methods result in significant anatomical and functional improvement. The combined FSIP with ILMF method may prevent post-operative macular hole development in cases with MTM and LMH., (© 2021.

Purpose: To describe the characteristics and management of full-thickness macular holes (MHs) that develop after pars plana vitrectomy for rhegmatogenous retinal detachment (RD)., Methods: Retrospective, interventional, consecutive case series. Patients who developed secondary full-thickness MHs after prior pars plana vitrectomy for RD over a 6-year period were included. The main outcome measures included optical coherence tomography (OCT) findings and the clinical course of full-thickness MHs., Results: A total of 11 eyes of 11 consecutive patients were included in the study. The mean age of the patients was 58.8 years (range, 47-70 years). The median time between RD repair and MH diagnosis was 36 months (range, 1 month-11 years). The fovea was attached to 10 eyes (91%) at the time of RD repair. OCT demonstrated epiretinal proliferation (EP) at the hole margin in 10 eyes (91%). MH spontaneously closed in 7 eyes (63%) but reopened in 5 eyes. A total of 7 eyes (63%) required a vitrectomy to repair the MHs. All MHs were closed at the last follow-up visit., Conclusion: Full-thickness MHs after pars plana vitrectomy for RD have features that are distinct from that of typical idiopathic MH. The presence of EPs is common, and MHs are prone to spontaneous closure and reopening. These findings suggest that EP may be associated with spontaneous hole closure and that long-term follow-up is necessary even if the MHs close spontaneously., (© 2021.

Background: Intraoperative optical coherence tomography (iOCT) has recently been introduced for the visualization of retinal structures within the operating microscope., Objective: The aim of this study was to analyze the behavior of the retina and morphological features during surgery for retinal detachment with macular involvement., Methods: A retrospective analysis of 41 consecutive eyes with macula-off retinal detachment, which were treated with pars plana vitrectomy (PPV) using iOCT. A qualitative analysis of morphological features of the retina at defined moments during surgery was carried out., Results: The visualization of macular detachment with iOCT was successful in 63% of cases and in the other cases the height of retinal detachment surpassed the maximum depth of the scan by iOCT. With perfluorodecalin 53.7% of eyes showed subretinal fluid and 22% of eyes showed a wave-like configuration of the outer retinal layers. In 61% of the eyes persisting subretinal fluid could be detected under the final tamponade. The amount of subretinal fluid could not be detected intraoperatively with the naked eye. In one case a macular hole could be newly identified intraoperatively and in three cases macular detachment could not be found at the start of surgery, although a detachment had been expected., Conclusion: The use of iOCT rarely leads to changes or extension of the intervention; however, it provides real-time information on intraretinal and subretinal fluid, which is sometimes in contrast to the clinical assessment. The relevance of persistent subretinal fluid and folds of the outer retinal layers after surgery remains unclear. It can be speculated whether this could serve as a prognostic factor for the postoperative outcome., (© 2020. The Author(s).)

Purpose: This study aims to analyze the success rate and functional outcome after revision surgery of persistent idiopathic full-thickness macular holes in a large patient cohort and to identify the optimal tamponade strategy and the value of new adjunctive manipulation techniques for persistent macular hole (pMH) closure., Methods: Retrospective, comparative, non-consecutive case series of all revisional surgeries for idiopathic pMH between 2011 and 2019 at the Eye Clinic Sulzbach were identified. Of 1163 idiopathic MH surgeries, 74 eyes of 74 patients had pMH. Of those, group 1 (n = 38) had vitrectomy with tamponade alone (20% sulfur hexafluoride gas, 15% hexafluoroethane gas, silicone oil 5000, Densiron®), while group 2 (n = 36) included tamponade with adjuvant manipulation (internal limiting membrane (ILM) translocation, subretinal fluid injection, epiretinal amniotic membrane, free retina graft, or autologous blood). Main statistical outcomes were anatomic closure rate, visual acuity (VA), minimum linear diameter (MLD), and base diameter (BD)., Results: Overall total anatomical success rate was 81.1% and mean VA improved 3.5 lines from LogMAR 1.03 ± 0.30 to 0.68 ± 0.38 (p < .001). Preoperative MLD or BD had no effect on total anatomic success (p = 0.074, p = 0.134, respectively). When comparing the two groups, slightly better anatomic success rates were achieved in group 1 (84.2%) compared to that in group 2 (77.8%) (p = 0.68). Final VA in group 1 (LogMAR 0.67 ± 0.39) outperformed group 2 (LogMAR 0.86 ± 0.38) (p = 0.03)., Conclusions: Revisional surgery for persistent idiopathic MH with tamponade alone had comparable anatomical closure but better VA outcomes, compared to tamponade with adjuvant manipulation., (© 2021.

Purpose: To investigate morphological and functional outcomes of the inverted internal limiting membrane (I-ILM) flap technique in large (≥ 400 μm) idiopathic full-thickness macular holes (FTMH) over a follow-up period of 12 months., Methods: In this retrospective study, 55 eyes of 54 consecutive patients were enrolled. Best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT, Heidelberg, Spectralis) were performed preoperatively as well as 1, 3, 6, 9, and 12 months postoperatively. Special focus was put on the reintegration of outer retinal layers and the different ILM flap appearances., Results: FTMH closure rate was 100% (55/55). BCVA significantly improved over the follow-up period of 12 months from 0.98 ± 0.38 LogMAR preoperatively to 0.42 ± 0.33 LogMAR at 12 months postoperatively (p < 0.001). There was no significant correlation between the three different ILM flap appearances and BCVA. Better preoperative BCVA, complete restoration of the external limiting membrane (ELM), higher macular hole index (MHI), and smaller MH base diameter were associated with higher improvement of BCVA., Conclusion: Our study highlights the favorable morphological and functional outcomes of the I-ILM flap technique in the short as well as in the long term. While complete ELM restoration revealed to be an important factor for improvement in BCVA, the different postoperative ILM flap appearances seem not to be related to BCVA., (© 2021. The Author(s).)

Purpose: To report the safety, anatomical and functional outcomes of autologous neurosensory retinal transplant in patients with a refractory large unclosed macular hole., Patients and Methods: This is a prospective case series of four patients with large chronic macular hole that underwent vitrectomy and free-flap neurosensory retinal transplantation surgery with silicone oil tamponade. The hole was closed with an autologous retinal transplant of an approximate diameter of 1.5-1.8 mm, harvested outside the vascular arcades. Anatomical and functional outcomes were assessed using best-corrected visual acuity (BCVA-Snellen), optical coherence tomography (OCT), OCT angiography, microperimetry (MP), and multifocal electroretinography (mfERG)., Results: There were 2 male and 2 female patients with median age of 73 (60-81) years. The median follow-up period was 17 (13-23) months. The median preoperative size of the macular hole was 1872.5 (868-2591) μm at the widest basal diameter and 828 (556-1099) μm at the minimum diameter. Surgery resulted in the anatomical closure of the macular hole in all cases. The OCT showed structural integration of the transplant and reappearance of the inner segment ellipsoid to different extents. The BCVA improved from preoperative 0.1 (6/60; + 1.0 logMAR), 0.1 (6/60; + 1.0 logMAR), 0.05 (6/120; + 1.3 logMAR), and 0.005 (6/1200; + 2.3 logMAR) to 0.2 (6/30; + 0.7 logMAR) postoperatively in cases 1, 2, and 4, and to 0.1 (6/60; + 1.0 logMAR) in case 3. MP showed retinal function in the region corresponding to the area of the transplant (circle of 1.8 mm in diameter) in all patients after the surgery (median sensitivity in that region was 4.0 dB, range 1.8-12.4 dB). Improvement was noted in the patient that had MP performed before the surgery (mean sensitivity improved from 0 to 1.8 dB). Detectable function was mostly located in the peripheral regions of the transplant. Multifocal ERG showed abnormal function of the central ring and normal function of the second ring in 3 of 4 cases. The OCT angiography showed normal perfusion, without signs of neovascularization. There were no intra- or postoperative complications., Conclusion: Autologous retinal transplantation surgery is a successful technique for closing of large refractory macular holes. The procedure is safe and provides good anatomical results. Visual acuity, microperimetry, and mfERG suggest some gradual functional integration of outer regions of the transplants, but no central functional restitution has been detected as yet.

Purpose: To develop an equation for estimating the vitreous chamber volume in pseudophakic patients based on the axial length of the eye., Methods: A consecutive series of patients who underwent vitrectomy surgery for a macular hole or an epiretinal membrane were enrolled. The inclusion criteria were as follows: having pseudophakia, being older than 50 years, and having eyes with axial length ranging from 21 to 26 mm. Before the surgery, the axial length was measured using optical biometry. Pars plan vitrectomy was performed, and, after the fluid-air exchange, the vitreous chamber was filled with Brilliant Blue G (0.005%). The infused volume of each eye was recorded. Then, epiretinal membrane peeling or internal limiting membrane peeling and a new fluid-air exchange were performed. Main outcomes and measures were the vitreous chamber volume and axial length., Results: The sample consisted of 112 patients. The mean [standard deviation (SD), range] age was 71 years (7, 53-90). Sixty-five individuals (58%) were women. In 58 (51.8%) patients, surgery was performed on the right eye. The mean (SD; range) axial length was 23.78 mm (0.93; 21.55-25.26), and the mean (SD; range) vitreous chamber volume was 4.96 mL (0.69; 3.60-6.40). Pearson's correlation coefficient (r = 0.950; p < 0.01) was positive, and the coefficient of determination (R 2 ) was 0.902. The estimated regression equation was Y = 0.71X - 11.84, where Y was the vitreous chamber volume, X was the axial length of the eye, the linear coefficient for the straight line was - 11.83, and the angular coefficient was 0.71 (p < 0.01)., Conclusion: These data suggest that the vitreous chamber volume is significantly correlated with the axial length and the former could probably be calculated using biometry. New studies with larger samples will be required to confirm these observations and will allow the development of an algorithm (perhaps non-linear) that includes extreme axial length values and that takes into account other factors such as the status of the lens and sex.

Aim: To compare the sensitivity of Optomap Panoramic 200 and Clarus 500 in detecting peripheral retinal breaks that required treatment., Methods: This prospective study enrolled consecutive patients undergoing laser for treatment-requiring peripheral retinal breaks from May 2019 to July 2019. The patients first underwent indirect ophthalmoscopy examination with scleral indentation by a retinal consultant and then ultra-widefield imaging by a single trained technician on Optomap 200 and Clarus 500 in all nine ocular gazes. The images were analysed by two independent investigators to look for the number and location of the breaks. The sensitivity of each platform was calculated as the number of treatment-requiring breaks identified by the system divided by the number of breaks identified on clinical examination., Results: Clinical examination of 49 eyes (41 patients) showed 116 treatment-requiring breaks. Overall sensitivity for identifying such breaks for Optomap and Clarus was 80.2% (n = 93) and 74.1% (n = 86) respectively (p = 0.274). The sensitivities in superior (p = 0.665), temporal (p = 0.146) and inferior (p = 0.889) quadrants were statistically similar for both the platforms. The sensitivity of Optomap was slightly higher than Clarus in emmetropic (p = 0.046) and phakic (p = 0.061) eyes, but similar in myopic (p = 0.448) and pseudophakic (p = 0.191) eyes., Conclusion: The ability to detect treatment-requiring retinal breaks is similar for both Optomap and Clarus systems.

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.

Background: Age, preoperative visual acuity and macular hole size have been reported to be prognostic markers for the postoperative outcome in patients with full thickness macular holes (FTMH)., Objective: A retrospective observational clinical study was performed in order to compare the postoperative course after conventional internal limiting membrane peeling (c-ILM) and inverted flap ILM peeling (i-ILM). Patients with i‑ILM peeling had preoperatively a significantly larger macular hole MATERIAL AND METHODS: In this study 45 consecutive patients with a full thickness macular hole (FTMH) were divided into two groups (c-ILM vs. i ILM) and evaluated with respect to the postoperative best corrected visual acuity (BCVA) and retinal morphology. Using spectral domain optical coherence tomography (SD-OCT) the integrity of the outer retinal layers, external limiting membrane (ELM), ellipsoid zone (EZ) and outer photoreceptor outer segments (OS) were analyzed postoperatively for at least 6 months., Results: The preoperative aperture in the i‑ILM group was significantly larger (i-ILM = 408.4 µm, SD = 157.5 µm; c‑ILM = 287.4 µm, SD = 104.9 µm; p = 0.01). The preoperative BCVA and postoperative BCVA after 1 month were significantly better in the group with c‑ILM peeling (p = 0.03 and p = 0.001). The postoperative BCVA after at least 6 months showed no significant difference between the two groups (p = 0.24). The ELM was the first of the outer retinal layers to show postoperative recovery in both groups., Conclusion: Using the i‑ILM peeling technique in this consecutive series it seemed to be possible to achieve a similar postoperative visual outcome in patients with a large FTMH as for patients with a smaller FTMH operated on with the c‑ILM peeling technique.

Large, persistent or chronic macular holes still represent a surgical challenge, which can be addressed using the presented surgical technique. A subretinal injection of balanced salt solution (BSS) at the posterior pole of the macular region is performed during transconjunctival pars plana vitrectomy in order to induce an elevation of the neurosensory retina in the macular region. The hole is then attenuated during fluid-air exchange, followed by a gas or silicone oil tamponade. The presented technique appears to be useful for large and persistent macular holes, which are not suitable for conventional macular hole surgery. The exact patient information on the potential outcome of surgery in this specific group of patients seems particularly important.

Purpose: To compare functional and anatomic outcomes of combined pars plana vitrectomy (PPV) and phacoemulsification (phaco) versus PPV and deferred phaco in patients with full-thickness macular hole (FTMH) and no significant cataract., Methods: Thirty-four patients were randomized to group 1 (combined PPV/phaco) and 34 to group 2 (PPV/deferred phaco). Group 2 patients could undergo phaco any time after FTMH surgery if significant cataract developed., Results: Sixty-five patients (33 group 1 and 32 group 2) completed the 12-month visit. Mean ± SEM logMAR best-corrected visual acuity (BCVA) was 0.92 ± 0.04 and 0.90 ± 0.04 at baseline and improved significantly to 0.60 ± 0.05 and 0.58 ± 0.05 at month 12 (p < 0.0001) in groups 1 and 2, respectively. There was no significant difference between the groups in mean BCVA at baseline or at month 12. Mean macular sensitivity (dB) was 18.22 ± 0.93 and 16.72 ± 0.93 at baseline and increased to 21.13 ± 0.86 and 21.07 ± 0.85 in groups 1 and 2, respectively (p < 0.05) with no significant difference between the groups (p = 0.449) at month 12. FTMH closure rate was 73% and 75% in groups 1 and 2, respectively (p = 0.834)., Conclusion: Among patients with FTMH and no significant cataract at baseline, combined PPV/phaco was associated with similar BCVA, microperimetry, and FTMH closure outcomes at 1-year compared with PPV/deferred phaco., Trial Registration: ( clinicaltrials.gov.br ): Ensaios clínicos brasileiros: RBR-3wmd9s; UTN number: U1111-1190-5013; Plataforma Brasil CAAE number: 50455415.3.0000.5440; IRB number: 1.433.000.
