Abstract
PURPOSE To evaluate the efficacy of vitrectomy with epiretinal proliferation (EP) sparing for full-thickness macular hole accompanied by EP. METHODS A multicenter, retrospective study. Eyes were divided into two groups: the sparing group (Group S) included eyes in which the EP around the hole was peeled and preserved, whereas the removal group (Group R) included eyes in which the EP was partially or completely removed. The internal limiting membrane was peeling in all eyes. RESULTS Forty-six eyes were included. Twenty-five eyes were in Group S, and 21 eyes were in Group R, with no difference in preoperative best-corrected visual acuity (BCVA) ( P = 0.96). After primary surgery, macular holes were closed in all eyes, and there were no complications in either group. Postoperative 12-month BCVA significantly improved in both groups (both P < 0.01), while Group S had better 12-month BCVA than Group R ( P = 0.016). In the multivariable analysis, EP sparing was associated with better BCVA at 12 months ( P = 0.006) after accounting for the minimal macular hole size and preoperative BCVA. CONCLUSION Epiretinal proliferation sparing and removal were both safe and effective techniques, while EP sparing may provide a favorable outcome for eyes with full-thickness macular hole and EP.

Quiroz-Reyes MA, Quiroz-Gonzalez EA, Quiroz-Gonzalez MA, Lima-Gomez V. Novel surgical approaches for treating myopic traction maculopathy: a meta-analysis. BMC Ophthalmol 2024; 24:105. [PMID: 38443856 PMCID: PMC10913604 DOI: 10.1186/s12886-024-03374-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 02/26/2024] [Indexed: 03/07/2024] Open
Abstract
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.

Fovea-sparing internal limiting membrane peeling with inverted flap technique versus standard internal limiting membrane peeling for symptomatic myopic foveoschisis. Sci Rep 2024; 14:2460. [PMID: 38291124 PMCID: PMC10828410 DOI: 10.1038/s41598-024-53097-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 01/27/2024] [Indexed: 02/01/2024] Open
Abstract
To study the long-term outcomes of standard ILM peeling and fovea sparing with inverted flap (FSIF) peeling for symptomatic myopic foveoschisis (MF). This retrospective observational study included 36 eyes of 34 consecutive patients who underwent vitrectomy with standard ILM peeling and FSIF peeling for MF between April 2012 and march 2020. The primary outcome measures included best-corrected visual acuity (BCVA) and central foveal thickness (CFT) at 1 month and final visit and postoperative development of macular hole. There were 14 eyes in the standard ILM peeling group and 22 eyes and in the FSIF peeling groups with a mean FU of 34.2 months (SD 23.3; min. 12-max. 96) and 27.7 months (SD 14.9; min. 12-max. 63), respectively. In both groups BCVA was not significantly improved at 1 month but improved at last visit from 0.55 ± 0.21 to 0.37 ± 0.29 in the standard ILM peeling group (P = 0.0154) and from 0.57 ± 0.27 to 0.28 ± 0.23 in the FSIF peeling group (P < 0.0001). At 1 month and final visit CMT decreased from 572 ± 183.5 µm to 277.5 ± 95.2 µm and to 250.4 ± 96.1 µm, respectively, in the standard ILM peeling group and from 589.9 ± 189.8 µm to 383 ± 110.1 µm and 162.3 ± 74.8 µm in the FSIF peeling group (P < 0.001 for both groups at both time-points). The preoperative and postoperative BCVA and CMT showed no significant differences between groups. Three of the eyes in the standard ILM peeling group developed postoperative macular hole at 1, 10, 24 months, respectively, and none of the eyes in the FSIF peeling group. Multivariate analysis revealed that a better BCVA was the only independent factor correlated with the final BCVA. In this study, standard ILM peeling and FSIF peeling were both beneficial in improving the anatomy and function of eyes with MF. Postoperative MH may occur up to 2 years after standard peeling and seem effectively prevented by FSIF peeling.

Efficacy of Vitrectomy With Tamponade Versus No Tamponade for Myopic Traction Maculopathy: A Multicenter Study (SCHISIS Report No.1). Am J Ophthalmol 2023; 254:182-192. [PMID: 37343740 DOI: 10.1016/j.ajo.2023.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 06/05/2023] [Accepted: 06/08/2023] [Indexed: 06/23/2023]
Abstract
PURPOSE To evaluate the influence of tamponade on the visual and anatomic outcomes of pars plana vitrectomy for myopic traction maculopathy (MTM). DESIGN Multicenter, retrospective clinical cohort study. METHODS Consecutive eyes that underwent vitrectomy for advanced MTM with tamponade of air, sulfur hexafluoride (SF6), or perfluoropropane (C3F8) or without tamponade with a minimum follow-up of 12 months were included. Main outcome measures included postoperative visual acuity (VA) at 12 months in eyes with vs without tamponade. RESULTS We included a total of 193 eyes (193 patients) in this study; 136 eyes (70%) treated with tamponade were compared with 57 eyes (30%) treated without tamponade. Baseline characteristics did not differ significantly between the groups. Both groups showed significant visual improvement at 12 months (both P < .001). However, postoperative visual acuity and visual improvement at 12 months were significantly better (P = .003 and P = .028, respectively) in eyes without tamponade, although the MTM in these eyes without tamponade took longer to resolve (P = .039). Retinal thickness and the ellipsoid zone were more preserved in eyes without tamponade (P < .001 and P = .001, respectively). Complications such as macular holes did not differ between the groups. A novel imaging finding of "schisis bending (accordioning)" was identified during MTM resolution. CONCLUSIONS Vitrectomy either with or without tamponade for MTM was effective in improving vision in this study. However, eyes without tamponade experienced even better visual improvement and preserved retinal anatomy, despite a longer schisis resolution time. Surgery without tamponade may achieve better visual outcomes.

Abstract
PURPOSE To evaluate the incidence, pathogenesis, risk factors, and treatment outcomes of postoperative macular hole (MH) after pars plana vitrectomy (PPV) for myopic traction maculopathy (MTM). DESIGN Multicenter, interventional, retrospective case series. SUBJECTS Consecutive eyes that underwent PPV for MTM with a minimum 6-month follow-up. METHODS We investigated the characteristics and treatment outcomes of postoperative MH after MTM surgery. MAIN OUTCOME MEASURES Incidence, risk factors, and anatomic and visual outcomes of postoperative MH. RESULTS We included 207 eyes (207 patients) with a mean follow-up of 25.9 months. During follow-up, 24 (11.6%) eyes developed MH (10 with concurrent MH retinal detachment); 15 eyes within 30 days (early), 4 eyes between 31 and 180 days (intermediate), and 5 eyes after 180 days (late). Logistic regression analysis revealed male gender (odds ratio [OR], 2.917; 95% confidence interval [CI], 1.198-7.100; P = 0.018), thinner preoperative choroidal thickness (OR, 0.988; 95% CI, 0.976-1.000; P = 0.048), and use of indocyanine green for internal limiting membrane peeling (OR, 2.960; 95% CI, 1.172-7.476; P = 0.022) as significant risk factors for postoperative MH. Internal limiting membrane peeling with a fovea-sparing technique tended to protect against postoperative MH, but it was not statistically significant (P = 0.096), because 1 eye still developed MH. Postoperative MHs were treated by observation (6 eyes), in-office octafluoropropane (C3F8) gas injection (7 eyes), or PPV (11 eyes). Macular hole closure was achieved in 20 eyes (83%). The hole closure rate was 67% (4/6 eyes) after observation, 71% (5/7 eyes) after C3F8 gas injection, and 91% (10/11 eyes) after PPV. However, visual outcomes were significantly worse for eyes with postoperative MH than those without (0.38 ± 0.43 vs. 0.68 ± 0.46; P = 0.002). CONCLUSIONS Postoperative MH may occur in 11.6% of patients with MTM at any time after surgery. Retreatment resulted in relatively favorable anatomic closure but unfavorable visual outcomes.

Abstract
PURPOSE To discuss a case of a macular hole formation after vitrectomy for myopic retinoschisis with foveal detachment and spontaneous closure, during long-term follow-up. METHODS Case report. RESULTS A 71-year-old man with myopic retinoschisis with foveal detachment had a vitrectomy with internal limiting membrane peeling combined with cataract surgery in the left eye. The preoperative best-corrected visual acuity was 8/20, and the axial length was 27.11 mm. A macular hole with foveal detachment was observed 1 month after surgery. However, the macular hole closed spontaneously with foveal detachment at 4 months of follow-up. Foveal detachment resolved, and the best-corrected visual acuity improved to 20/20 at nine months of follow-up. CONCLUSION This case suggests that the macular hole formed after vitrectomy for myopic retinoschisis with foveal detachment with internal limiting membrane peeling can close spontaneously.

Displacement of the retina and changes in the foveal avascular zone area after internal limiting membrane peeling for epiretinal membrane. Jpn J Ophthalmol 2023; 67:74-83. [PMID: 36370235 DOI: 10.1007/s10384-022-00964-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 09/15/2022] [Indexed: 11/13/2022]
Abstract
PURPOSE We investigated the differences in displacement of the outer and inner macular retina toward the optic disc after vitrectomy with internal limiting membrane (ILM) peeling for epiretinal membrane (ERM). Foveal avascular zone (FAZ) area changes were also investigated. STUDY DESIGN Retrospective observational study METHODS: This retrospective observational case series included 45 eyes of 43 patients that underwent vitrectomy with ERM and ILM peeling for ERM and 38 normal eyes. The locations of the centroid of the FAZ (C-FAZ, center of the foveal inner retina) and foveal bulge (center of the foveal outer retina) were determined using 3×3mm superficial optical coherence tomography angiography. C-FAZ and foveal bulge displacements, and the pre- and postoperative FAZ areas and their associated factors, were investigated. RESULTS Postoperative C-FAZ dislocated significantly more toward the optic disc than in pre-operative or normal eyes (P<0.001). C-FAZ and foveal bulge displaced toward the optic disc after surgery; C-FAZ showed significantly greater displacement than foveal bulge (P<0.001). The pre- and postoperative FAZ areas were correlated (P=0.01). Preoperative FAZ areas ≧0.10mm2 were reduced after surgery, and FAZ areas < 0.10mm2 were increased, independent of foveal displacement. CONCLUSION ILM peeling during vitrectomy for ERM caused larger displacement of the inner and smaller displacement of the outer retinas, towards the optic disc. Postoperative changes in the FAZ area were dependent on the baseline FAZ area, but not on the foveal displacement. ILM may physiologically exert centrifugal tractional forces on the fovea.

Abstract
PURPOSE To assess the sequence of anatomical resolution of myopic foveoschisis (MFS) after vitrectomy. DESIGN Monocentric retrospective observational case series. SUBJECTS The files of consecutive patients with MFS who underwent vitreoretinal surgery and were followed postoperatively for at least 6 months were reviewed. METHODS Patients underwent pars plana vitrectomy for MFS. The central foveal thickness (CFT) was measured. The presence of a foveal involvement, and/or outer retinoschisis (ORS), with or without inner retinoschisis (IRS), and foveal detachment (FD) were analyzed. Anatomical success was defined as the resolution of foveal ORS and FD. MAIN OUTCOME MEASURES The main outcome was the time to resolution of the different morphologic features of MFS after surgery. RESULTS Thirty-nine eyes of 36 patients were included in the analysis. The mean follow-up was 14.8 ± 12.9 months (range, 6-84 months). Anatomical success was achieved in 82% of cases at the end of the follow-up and in > 80% of cases during the first year. The CFT was significantly decreased in 79% of cases at 3 months. Inner retinoschisis, present in 18 eyes (46%), resolved in all cases after a median time of 1 month. Foveal ORS, present in all cases, resolved in 82% of cases after a median time of 3 months. The FD, present in 23 eyes (59%), resolved in 91% of cases after a median time of 6 months. Extrafoveal ORS resolved in 59% of cases after a median time of 12 months. The mean best-corrected visual acuity significantly improved from 0.80 ± 0.64 logarithm of the minimum angle of resolution (logMAR) (Snellen Eq 20/148) to 0.48 ± 0.52 logMAR (Snellen Eq 20/70). CONCLUSIONS Most MFS (80%) are completely resolved during the first year. The decrease in CFT and early resolution of IRS could be used as early biomarkers of surgical success.

Fovea sparing versus complete internal limiting membrane peeling for myopic traction maculopathy: a meta-analysis. Int Ophthalmol 2021; 42:765-773. [PMID: 34623570 DOI: 10.1007/s10792-021-02042-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 09/22/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE Myopic traction maculopathy (MTM) is the leading cause of visual loss in high myopia. The purpose of this study was to compare the outcomes of pars plana vitrectomy (PPV) with fovea-sparing internal limiting membrane (ILM) peeling and complete ILM peeling for MTM. METHODS A comprehensive literature search was performed to find relevant studies. A meta-analysis was conducted by comparing the weighted mean differences (WMD) in the change of best-corrected visual acuity (BCVA) and central foveal thickness (CFT) from baseline and calculating the odd ratios (OR) for rates of complete reattachment (CR) and postoperative macular hole (MH) formation. RESULTS Ten studies were selected, including 417 eyes (172 eyes in the fovea-sparing ILM peeling group (FSIP) and 245 eyes in complete ILM peeling group (CIP)). There was no significant difference in terms of mean change in CFT from baseline and the rate of CR(WMD = 3.53, 95% CI, -25.56 to 32.63, P = 0.81, and OR = 1.41, 95% CI, 0.81 to 2.44, P = 0.22). FSIP was superior to CIP in terms of mean change of logMAR BCVA post operation (WMD = -0.09, 95% CI, -0.15 to -0.03, P = 0.003), and associated with a significantly lower frequency of postoperative MH formation (OR = 0.19, 95% CI, 0.07 to 0.50, P = 0.0008). CONCLUSION FSIP resulted in similar anatomic outcomes compared to CIP, but resulted in better visual acuity and lower rates of postoperative MH development.

Abstract
INTRODUCTION Myopic traction maculopathy (MTM) is a major cause of impaired vision in eyes with high myopia, which is characterized by retinal thickening, retinoschisis, lamellar macular hole (MH), and foveal retinal detachment. Pars plana vitrectomy (PPV) with fovea-sparing internal limiting membrane peeling (ILMP) has been developed to theoretically prevent postoperative MH formation and improve best-corrected visual acuity (BCVA) gain for MTM compared with the complete ILMP. However, in previous studies, the anatomic and visual outcomes still remain uncertain and controversial. OBJECTIVES The aim of this study was to evaluate the anatomic and visual outcomes of vitrectomy with fovea-sparing ILMP for the treatment of MTM compared with complete ILMP. METHODS Articles from PubMed, EMBASE, Web of Science, and Cochrane Library were systematically retrieved. The main outcomes were the rate of a postoperative MH and visual improvement of BCVA (converted to logarithm of the minimum angle of resolution [logMAR]). The secondary outcomes were the proportion of patients with visual improvement, the proportion of anatomic success, preoperative and postoperative BCVA, preoperative and postoperative central fovea thickness, and time to anatomic resolution. RESULTS There was a higher rate of postoperative MH formation (odds ratio [OR] 5.64; 95% confidence interval [CI]: 1.72-18.44; p = 0.004) and less improvement of BCVA in logMAR (mean difference [MD] -0.09; 95% CI: -0.18 to 0.00; p = 0.04) in the complete ILMP group. However, postoperative BCVA (MD 0.14; 95% CI: 0.00-0.27; p = 0.05), the proportion of patients with visual improvement (OR 0.39; 95% CI: 0.15-1.02; p = 0.05), postoperative central foveal thickness (MD -10.02; 95% CI: -24.4 to 4.36; p = 0.17), the rate of anatomic success (MD 0.39; 95% CI: 0.15-1.03; p = 0.06), and time to resolution (MD -1.65; 95% CI: -3.66 to 0.36; p = 0.11) showed no significant differences. CONCLUSION PPV combined with the fovea-sparing ILMP could contribute to a lower MH formation rate and more improvement of BCVA in logMAR than PPV combined with complete ILMP.

Efficiency comparison with fovea-sparing internal limiting membrane peeling and complete internal limiting membrane peeling for treating myopic traction maculopathy. Graefes Arch Clin Exp Ophthalmol 2021; 260:73-81. [PMID: 34309768 DOI: 10.1007/s00417-021-05320-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/17/2021] [Accepted: 07/07/2021] [Indexed: 11/28/2022] Open
Abstract
PURPOSE To explore whether the efficacy of fovea-sparing internal limiting membrane peeling (FS-ILMP) is better than that of complete internal limiting membrane peeling (ILMP). METHODS This retrospective clinical study included 34 cases (34 eyes) with myopic traction maculopathy collected from June 2017 to February 2019. Twenty-three-gauge (23-G) pars plana vitrectomy (23G PPV) was performed on all patients. In the FS-ILMP group, 18 eyes retained the internal limiting membrane (ILM) of about 1 to 1.5 papillary diameter centered on fovea centralis, while in the standard ILMP group, the ILM was completely removed from 16 eyes. The best corrected visual acuity (BCVA), central foveal thickness (CFT), and other indexes were collected before and 6 months after surgery. RESULTS There was no significant difference in baseline clinical characteristics between the two groups. CFT and BCVA were significantly improved in both FS-ILMP and standard ILMP group, but the postoperative BCVA of the FS-ILMP group was significantly better than that of the standard ILMP group (P < 0.001). Two cases of subretinal effusion in macula were recorded in the FS-ILMP group, and three eyes in the standard ILMP group developed macular holes after surgery. Although both treatments relieved the mechanical traction of macular fovea, the patients in the FS-ILMP group showed better clinical outcomes in various aspects. CONCLUSION These results improved our understanding of the clinical application of vitrectomy combined with preservation of ILM upon the fovea centralis, which might lay a foundation for in-depth study on the treatment of myopic traction maculopathy.

Vitrectomy With Silicone Oil Tamponade and Without Internal Limiting Membrane Peeling for the Treatment of Myopic Foveoschisis With High Risk of Macular Hole Development. Front Med (Lausanne) 2021; 8:648540. [PMID: 34124090 PMCID: PMC8193352 DOI: 10.3389/fmed.2021.648540] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 04/06/2021] [Indexed: 11/19/2022] Open
Abstract
Purpose: To explore the efficiency and safety of the surgical procedure of pars plana vitrectomy (PPV) with silicone oil (SO) tamponade and without internal limiting membrane (ILM) peeling for myopic foveoschisis (MF) eyes with high risk of macular hole formation. Methods: Three eyes (three patients) with MF and foveal detachment were enrolled into the study. Comprehensive preoperative ophthalmological assessments, including best corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT) were performed on the eyes. Central foveal thickness (CFT) and thickness of continuous neurosensory retina at foveola were measured. All patients underwent PPV followed by SO tamponade and without ILM peeling. SO was removed when MF and retinal detachment were resolved. Patients were followed up postoperative at month 1, 3, 6, and 12. Results: All the three eyes achieved complete resolution of MF and foveal reattachment with an average SO tamponade period of 11.67 ± 0.58 months. The average CFT at 6 months was 91 ± 27.5 μm, hence reduced significantly from baseline at 365.3 ± 137.85 μm (P = 0.037). There was no postoperative macular hole formation despite the average preoperative sensory retina thickness of 58 ± 20.07 μm. Mean BCVA was improved from logMAR 1.43 ± 0.75 to logMAR 0.8 ± 0.75 on the last follow-up. Manageable SO-related complications were reported, including SO emulsification, ocular hypertension, and cataract. Conclusion: Vitrectomy with SO tamponade and without ILM peeling as an optional surgical protocol to treat MF is effective and safe, especially for MF eyes vulnerable to macular hole formation.

Abstract
PURPOSE To propose the Myopic Traction Maculopathy (MTM) management Table, based on the MTM Staging System (MSS). METHODS A retrospective review of 157 eyes affected by MTM, operated with pars plana vitrectomy (PPV), or macular buckle (MB) or combined surgery (MB + PPV). Each case was classified according to the MSS. Anatomical results were evaluated with OCT at an intermediate follow-up (3-6 months) and at a final follow-up (2-8 years), considering changes both in the foveal and in the retinal pattern. The number and type of operations needed were noted. The surgical complications were reported. RESULTS Primary surgery was MB for 83 eyes (52%), PPV for 36 (23%) and MB + PPV for 38 (24%). At intermediate follow-up, the retinal pattern was restored in 55.41% and foveal in 42.68%.Further surgery was indicated as PPV in 25.48%, MB in 14.65%. At the final follow-up, the retinal pattern was restored in 96.16% and the foveal pattern in 87.90%.BCVA improved at the final follow-up (p < 0.05). The complications of MB were not sight-threatening. The complications of PPV were FTMH in 67% cases in stages 2, 3, and 4. Cataract developed in 60% of phakic eyes. The complications of combined MB+PPV were cataract (56%) and PVR (5%). CONCLUSIONS Both PPV and MB may be used to treat MTM. PPV addresses the changes in the foveal pattern while MB addresses the changes in the retinal pattern. The MTM management table offers a proposal for the choice of type and timing of treatment customized per each stage of MTM.

Fovea-Sparing as Opposed to Total Peeling of Internal Limiting Membrane for Myopic Foveoschisis: A Systematic Review and Meta-analysis. Ophthalmol Retina 2020; 5:670-679. [PMID: 33307217 DOI: 10.1016/j.oret.2020.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 10/14/2020] [Accepted: 10/19/2020] [Indexed: 12/12/2022]
Abstract
TOPIC The effectiveness of fovea-sparing (FS) peeling of internal limiting membrane (ILM) to treat myopic foveoschisis (MF) has not been understood fully. The present meta-analysis aimed to compare postoperative visual and anatomic outcomes between FS peeling and total peeling (TP) of ILM in pars plana vitrectomy for the treatment of MF. CLINICAL RELEVANCE Postoperative macular hole (MH) development is not uncommon and is a serious complication after surgery for MF, with poor visual prognosis. Fovea-sparing peeling of ILM is expected to reduce the risk of postoperative MH; however, no statistically significant evidence exists to prove this hypothesis. In addition, its effect on postoperative visual acuity has not been clear. METHODS MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE were reviewed systematically, and studies that compared FS with total ILM peeling in MF surgery were retrieved. The protocol was registered in International Prospective Register of Systematic Reviews (identifier, CRD42020201675). Primary outcome measures were the postoperative best-corrected visual acuity (BCVA) and frequency of postoperative MH development. Certainty of evidence was evaluated by the Grading of Recommendations Assessment, Development and Evaluation system. RESULTS Eight studies with 300 eyes from 289 patients were included. All studies were nonrandomized and observational. The postoperative BCVA was significantly better in eyes treated with FS (mean difference [MD], -0.15 logarithm of the minimum angle of resolution [logMAR]; 95% confidence interval [CI], -0.24 to -0.05 logMAR; P = 0.002). The risk of postoperative MH was significantly lower in the FS group (odds ratio, 0.19; 95% CI, 0.06-0.56; P = 0.003). No significant difference was found in postoperative central foveal thickness (MD, 12.59 μm; 95% CI, -2.8 to 28.0 μm; P = 0.11). The certainty of evidence regarding lower frequency of postoperative MH after FS peeling was considered moderate, whereas the certainty regarding better postoperative BCVA after FS peeling was judged to be low. DISCUSSION Fovea-sparing peeling may contribute to better visual acuity outcome and lower risk of postoperative MH development in eyes with MF.
