RESUMO
PURPOSE: To report on macular hole repair in macular telangiectasia type 2 (MacTel2). DESIGN: Global, multicenter, retrospective case series. PARTICIPANTS: Patients undergoing surgery for MacTel2-associated full-thickness macular hole (MTMH). METHODS: Standardized data collection sheet distributed to all surgeons. MAIN OUTCOME MEASURES: Anatomic closure and visual outcomes of MTMH. RESULTS: Sixty-three surgeries in 47 patients with MTMH were included from 30 surgeons. Mean age was 68.1 years, with 62% female, 72% White, 21% East or South Asian, 2% African American, and 2% Hispanic or Latino. Procedures included 34 internal limiting membrane (ILM) peeling alone, 22 ILM flaps, 5 autologous retinal transplantations (ARTs), 1 retinotomy, and 1 subretinal bleb. For ILM peeling, preoperative visual acuity (VA) was 0.667 ± 0.423 logarithm of the minimum angle of resolution (logMAR). Minimum hole diameter (MHD) was 305.5 ± 159.4 µm (range, 34-573 µm). Sixteen of 34 ILM peels (47%) resulted in MTMH closure. At postoperative month 6, VA was stable at 0.602 ± 0.516 logMAR (P = 0.65). VA improved by at least 2 lines in 43% and at least 4 lines in 24%. For ILM flaps, preoperative VA was 0.878 ± 0.552 logMAR. MHD was 440.8 ± 175.5 µm (range, 97-697 µm), which was significantly larger than for ILM peels (P < 0.01). Twenty of 22 ILM flaps (90%) resulted in MTMH closure, which was significantly higher than for ILM peels (P < 0.01). At postoperative month 6, VA improved to 0.555 ± 0.405 logMAR (P < 0.05). VA improved by at least 2 lines in 56% and at least 4 lines in 28%. For ARTs, preoperative VA was 1.460 ± 0.391 logMAR. MHD was 390.2 ± 203.7 µm (range, 132-687 µm). All 5 ARTs (100%) resulted in MTMH closure. At postoperative month 6, VA was stable at 1.000 ± 0.246 logMAR (P = 0.08). Visual acuity improved at least 2 lines in 25%. CONCLUSIONS: Surgical closure of macular holes improved VA in 57% of MTMHs. Internal limiting membrane flaps achieved better anatomic and functional outcomes than ILM peeling alone. Autologous retinal transplantation may be an option for refractory MTMHs.

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.

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.

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.

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.
RESUMO
PURPOSE: Outcomes of retinal detachment (RD) have been discussed in detail in many reports of patients with retinitis pigmentosa (RP). This study tries to understand the outcomes of vitreoretinal (VR) surgery for indications other than RD in the eyes with RP. METHODS: This is a retrospective study that includes clinical data from January 2013 to December 2021. Patients with RP who were treated with a VR surgical intervention were included in the study. The primary outcome of the study was to assess the changes in best-corrected visual acuity. RESULTS: Forty-four eyes of 40 patients with RP were included in the study. Nearly half of the eyes (43%, 19/44) presented from 1 month to 1 year after the onset of diminished vision, with or without floaters. The mean ± standard deviation (SD) best-corrected visual acuity (BCVA) at presentation was 1.30 ± 0.79 logMAR (20/400 ± 20/125). The major surgical indications were vitreous opacities (43.2%, 19/44) and subluxated/dislocated cataractous lenses (25%, 11/44). The median follow-up duration was 8 months (interquartile range (IQR): 1.5-27). Approximately 77% (34/44) of the eyes had improvement in vision. The mean postoperative BCVA at the last follow-up was 0.95 ± 0.73 logMAR (p-value: 0.03). CONCLUSIONS: Most eyes with RP recovered well after VR surgical interventions, with short-term improvements in visual acuity. It may be crucial to address the vitreous opacities and membranes as they hinder the residual central island of vision in RP. However, appropriate counselling is required regarding the progressive nature of retinal neuronal degeneration.

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.
RESUMO
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 (R2 0.35), followed by minimum MH diameter (R2 0.24), delta CHW (R2 0.19), and MH base diameter (R2 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.

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 mm2, which decreased to 0.24 ± 0.07 mm2 1 month postoperatively (p < 0.001) and slightly increased to 0.25 ± 0.06 mm2 12 months postoperatively (p = 1.000). The FAZ area did not differ significantly from that of fellow eyes (0.39 ± 0.06 mm2, 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.

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.

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.
RESUMO
BACKGROUND: An idiopathic macular hole (IMH) is a full-thickness anatomic defect extending from the internal limiting membrane to the photoreceptor layer of the macula without any known cause. Recently, clinical laboratory markers of systemic inflammatory status derived from complete blood counts have been evaluated in ocular diseases. This study aimed to explore whether they could predict the development and progression of IMHs. METHODS: A retrospective review of 36 patients with IMH and 36 sex-and-age-matched patients with cataracts was conducted. We collected complete blood counts of all participating individuals and calculated systemic immunoinflammatory indicators. The maximum base diameter of the IMH (BD), minimum diameter of the IMH (MIN), height of the IMH (H), area of the intraretinal cyst (IRC), and curve lengths of the detached photoreceptor arms were measured on optical coherence tomography (OCT) images. We used these values to calculate the macular hole index (MHI), tractional hole index (THI), diameter hole index (DHI), hole form factor (HFF), and macular hole closure index (MHCI). We performed a receiver operating characteristic (ROC) curve analysis of 30 patients with IMH who were followed up 1 month after surgery. RESULTS: Lymphocyte counts were significantly higher in the IMH group. No other significant differences were observed between the IMH and control groups. Lymphocyte counts in the IMH group were significantly negatively correlated with MIN and BD and were significantly positively correlated with MHI, THI, and MHCI. However, lymphocyte counts were not significantly correlated with H, IRC, DHI, and HFF. In the ROC analysis, BD, MIN, MHI, THI, and MHCI were significant predictors of anatomical outcomes. According to the cut-off points of the ROC analysis, lymphocyte counts were compared between the above-cut-off and below-cut-off groups. Lymphocyte counts were significantly higher in the MIN ≤ 499.61 µm, MHI ≥ 0.47, THI ≥ 1.2, and MHCI ≥ 0.81 groups. There were no significant differences between the above-cut-off and below-cut-off BD groups. CONCLUSIONS: Although inflammation may not be an initiating factor, it may be involved in IMH formation. Lymphocytes may play a relatively important role in tissue repair during the developmental and postoperative recovery phases of IMH.

BACKGROUND: Performing a surgical task subjects the surgeon to multitudinal stressors, especially with the newer 3D technology. The quantum of cognitive workload using this modern surgical system in comparison to the Conventional microscope system remains unexplored. We evaluate the surgeon's cognitive workload and the surgical outcomes of macular hole(MH) surgery performed on a 3D versus a Conventional microscope operating system. METHODS: 50 eyes of 50 patients with MH undergoing surgery using the 3D or Conventional microscope visualization system. Cognitive workload assessment was done by real-time tools(Surgeons' heart rate [HR] and oxygen saturation[SPO2]) and self-report tool(Surgery Task Load Index[SURG-TLX] questionnaire) of three Vitreoretinal surgeons. Based on the SURG-TLX questionnaire, an assessment of the workload was performed. RESULTS: Of the 50 eyes, 30 eyes and 20 eyes underwent surgery with the Conventional microscope and the 3D system, respectively. No difference was noted in the MH basal-diameter(p = 0.128), total surgical-duration(p = 0.299), internal-limiting membrane(ILM) peel time(p = 0.682), and the final visual acuity (VA; p = 0.515) between the two groups. Both groups showed significant improvement in VA(p < 0.001) with a 90% closure rate at one-month post-surgery. Cognitive workload comparison, the intraoperative HR(p = 0.024), total workload score(P = 0.005), and temporal-demand dimension(p = 0.004) were significantly more in Conventional microscope group as compared to 3D group. In both the groups, the HR increased significantly from the baseline while performing ILM peeling and at the end. CONCLUSION: The surgeon's cognitive workload is markedly reduced while performing macular hole surgery with a 3D viewing system. Moreover, duration of surgery including ILM peel time, MH closure rates, and visual outcomes remains unaffected irrespective of the operating microscope system.

BACKGROUND: Macular hole (MH) development following scleral buckling (SB) surgery for rhegmatogenous retinal detachment (RRD) repair is rare. This study presents both full-thickness MH (FTMH) and lamellar MH (LMH) cases following SB for the treatment of RRD. METHODS: Clinical records of patients undergoing SB surgery for treatment of RRD at the Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2016 to December 2021 were reviewed, and cases with postoperative MH were selected. Clinical features and follow-up data were summarised, and possible causes were analysed. RESULTS: Among 483 identified cases (483 eyes), four eyes (three male patients, one female patient) had postoperative MH, with prevalence, mean age, and mean axial length of 0.83%, 43.5 ± 10.66 years, and 29.13 ± 3.80 mm, respectively. All patients did not undergo subretinal fluid (SRF) drainage. The mean time for detecting MH was 26 ± 15.5 days postoperatively. Macula-off RRD with high myopia and FTMH combined with retinal re-detachment were diagnosed in three patients. One patient had macula-on RRD with outer LMH. The average follow-up duration was 7.25 ± 1.5 months. The FTMH closed successfully after reoperation, while the outer LMH closed without intervention. Visual acuity insignificantly improved or slightly decreased in all patients. CONCLUSIONS: Patients with high myopia combined with macula-off RRD might be more susceptible to FTMH, causing MH related retinal detachment. Additionally, LMH following SB was noted in patients with macula-on RRD. Therefore, we should raise awareness of MH following SB for RRD repair.

BACKGROUND: To compare the surgical outcomes of the inverted internal limiting membrane (ILM) flap technique and ILM insertion for macular hole (MH) without retinal detachment in eyes with extremely high myopia. METHODS: In this retrospective study, we analyzed 22 eyes with an axial length ≥ 30.0 mm that had underwent MH surgery between April 2015 and August 2021. The surgical procedures involved either an inverted ILM flap or ILM insertion. The outcomes were compared between the two techniques. Closure of the MH was confirmed by optical coherence tomography (OCT). The best-corrected visual acuity (BCVA) was measured before and after surgery. Associated complications were documented. RESULTS: The median of axial length was 30.64 mm (range, 30.0-34.42). The MH closed in 100% (22/22) eyes and did not recur with a median follow-up of 12.5 months. For the inverted ILM flap technique, the median BCVA improved significantly from 0.80 logarithm of the minimum angle of resolution (logMAR) (range, 0.40-2.00) before surgery to 0.70 logMAR (range, 0.09-1.52) after surgery (p = 0.002). In addition, the median of final BCVA was better for the inverted ILM flap than ILM insertion (0.7 logMAR V.S. 1.00 logMAR; p = 0.016). CONCLUSIONS: In eyes with extremely high myopia, despite comparable effects on MH closure for both ILM insertion and the inverted ILM flap, the later technique achieved significantly better visual outcomes.

BACKGROUND: Myopic traction maculopathy (MTM) is a complication of pathological myopia and encompasses various pathological conditions caused by tractional changes in the eye. These changes include retinoschisis, foveal retinal detachment, and lamellar or full-thickness macular holes (FTMHs). This meta-analysis evaluated the safety and efficacy of novel surgical for treating MTM. METHODS: To compare the outcomes of different surgical approaches for MTM, multiple databases, including Web of Science, PubMed, Scopus, ClinicalTrials.gov, the Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Embase, and the Meta-Register of Controlled Trials, were comprehensively searched. The meta-analysis was performed using RevMan 5.1. RESULTS: Nine comparative studies involving 350 eyes were included in this meta-analysis. There were significant differences between fovea-sparing internal limiting membrane peeling (FSIP) and standard internal limiting membrane peeling (ILMP). Preoperative best-corrected visual acuity BCVA (standard mean difference (SMD): -0.10, 95% CI: -0.32 to 0.12) and central foveal thickness CFT (SMD: 0.05, 95% CI: -0.22 to 0.33) were not significantly different (p = 0.39 and p = 0.71, respectively). However, the postoperative BCVA improved significantly (SMD = - 0.47, 95% CI: - 0.80, - 0.14, p = 0.006) in the FSIP group compared to the standard ILMP group. Postoperative CFT did not differ significantly between the two groups (p = 0.62). The FSIP group had a greater anatomical success rate than the other groups, although the difference was not statistically significant (p = 0.26). The incidence of postoperative macular hole formation was significantly lower (OR = 0.19, 95% CI = 0.07-0.54; p = 0.05) in the FSIP group than in the standard ILMP group. The unique characteristics of highly myopic eyes, such as increased axial length and structural changes, may have contributed to the greater incidence of FTMH in the ILMP group. CONCLUSION: Based on the findings of this meta-analysis, FSIP is the initial surgical approach for early-stage MTM and has shown promising outcomes. However, to establish the safest and most efficient surgical technique for treating different MTM stages, further comparative studies, specifically those focusing on ILMP and FSIP, are necessary. TRIAL REGISTRATION: Retrospectively registered.

INTRODUCTION: The aim of this study was to describe differences in the vitreomacular interface (VMI) in idiopathic epiretinal membrane (ERM) foveoschisis compared to macular pseudohole (MPH) and lamellar macular hole (LMH). METHODS: We analysed surgically excised epiretinal material and internal limiting membrane (ILM) specimens obtained from 16 eyes of 16 patients with ERM foveoschisis (6 eyes), MPH (5 eyes), and LMH (5 eyes) during standard pars plana vitrectomy (PPV) with membrane peeling. The three entities were classified according to the newly introduced optical coherence tomography (OCT) terminology. Transmission electron microscopy (TEM) was used to describe the ultrastructural features. RESULTS: We found fibrocellular epiretinal tissues in all samples analysed. However, the cell and collagen composition of the VMI differed between groups. Eyes with ERM foveoschisis were characterized by a higher number of cells, multilayered membranes, and thick strands of vitreous collagen embedding the major cell types of myofibroblasts compared to MPH. Eyes with MPH also showed a predominance of myofibroblasts, but these were located directly on the ILM with no collagen between the cells and the ILM. Eyes with LMH showed a thick, multilayered epiretinal proliferation consisting mainly of non-tractional glial cells, corresponding to hypodense epiretinal proliferation on OCT. Eyes with ERM foveoschisis and MPH were more likely to have incomplete PVD compared to LMH in terms of posterior hyaloid status. DISCUSSION/CONCLUSION: Tractional ERMs in eyes with ERM foveoschisis and MPH differ in their ultrastructure. The main difference is in the amount and topographical distribution of vitreous collagen. However, the epiretinal cell types are predominantly myofibroblasts in both entities. This highlights the importance of distinguishing ERM foveoschisis from both MPH and LMH in terms of pathogenesis and surgical peeling procedures.

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

INTRODUCTION: So far, there has been no closure grade system synthesizing morphological and microstructural features for large idiopathic macular holes (IMHs) treated by vitrectomy and internal limiting membrane (ILM) peeling. This study aimed to propose a concise one and explore its relevance with visual acuity and the related preoperative factors. METHODS: Consecutive patients with large IMHs (minimum diameter >400 µm), undergoing vitrectomy and ILM peeling, obtaining primary closure and regularly followed-up were enrolled. Preoperative clinical charts and spectral-domain optical coherence tomography (SD-OCT) parameters were reviewed. SD-OCT images and best corrected visual acuity (BCVA) were assessed at 1, 4, and 10 months postoperatively. SD-OCT features at last visit were categorized by BCVA significance, and preoperative risk factors were analyzed. RESULTS: Sixty-eight eyes from 64 patients were enrolled. The 10-month postoperative SD-OCT images were categorized into closure grade 1, 2, and 3 with successively decreased BCVA (p < 0.001). During early follow-up, part of grades 2 and 3 could evolve into the upper grade, respectively, but grade 3 could never evolve into grade 1 and exhibited the least satisfactory long-term BCVA. Binary logistic regression showed that large minimum linear diameter (MLD) was a risk factor for grade 3 occurrence (p < 0.001), with a cutoff value of 625.5 µm from the receiver operating characteristic curve for MLD predicting grade 3 occurrence (p = 0.001). CONCLUSION: Long-term closure status of large IMHs could be categorized into three grades with BCVA significance. Large horizontal MLD is a risk factor for occurrence of grade 3 closure with unsatisfactory visual recovery.

BACKGROUND: Presently, the global prevalence of myopia and high myopia reaches approximately 1.95 billion and 277 million individuals, respectively. Projections suggest that by 2050, the number of people with myopia may rise to 4.758 billion and those with high myopia to 938 million. In highly myopic eyes, the occurrence of MF is reported to be as high as 8-33%. SUMMARY: This review comprehensively addresses the classification, pathogenesis, natural progression, concomitant pathologies, and therapeutic strategies for macular foveoschisis in highly myopic patients. KEY MESSAGES: In recent years, macular foveoschisis has emerged as a prevalent complication in individuals with high myopia, primarily resulting from the combination of inward traction by vitreoretinal adhesions and outward traction exerted by posterior scleral staphyloma on the retina. While some maintain partial visual stability over an extended period, others may progress to macular holes or even retinal detachment. For highly myopic patients with macular foveoschisis, the mainstay procedures are vitrectomy, macular buckle, and posterior scleral reinforcement. However, there is controversy about whether to perform inner limiting membrane peeling and gas filling.
