ABSTRACT
AIM: To evaluate the efficacy and safety of foveal-sparing internal limiting membrane peeling(FSIP)or complete internal limiting membrane peeling(CMIP)for the treatment of myopic traction maculopathy(MTM)during vitrectomy.METHODS: CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library, and Web of Science were searched from January 1th 2000 to July 1th 2022, and studies that compared FSIP and CMIP for MTM were collected. The change and recovery rate of best corrected visual acuity(BCVA), incidence of full-thickness macular hole(FTMH), change of central foveal thickness(CFT)and the rate of complete reattachment.RESULTS: A total of 484 eyes from 12 literatures were included, with 203 eyes in the FSIP group and 281 eyes in the CMIP group. The results of Meta-analysis showed that FSIP group were superior to the CMIP group in the mean change of BCVA(SMD=0.52, 95%CI: 0.20～0.85, P=0.002), the improvement rate of BCVA(RR=1.50, 95%CI: 1.22～1.85, P=0.0002)and the incidence of postoperative FTMH(RR=0.23, 95%CI: 0.10～0.54, P=0.0008). There was no statistical difference between the two surgical methods in terms of mean change in CFT(SMD=0.04, 95%CI: -0.19～0.26, P=0.75)and the rate of complete reattachment(RR=1.12, 95%CI: 0.94～1.32, P=0.20).CONCLUSION: FSIP have similar anatomical outcomes compared to CMIP, but FSIP resulted in better visual acuity and lower incidence of postoperative FTMH.
ABSTRACT
AIM: To explore the pathogenesis and surgical outcomes of different types of myopic traction maculopathy(MTM)using optical coherence tomography(OCT).METHODS: A total of 193 patients(210 eyes)with MTM were retrospectively included, of which 74 eyes(35.2%)underwent vitrectomy combined with internal limiting membrane(ILM)peeling. The patients were categorized into three groups: foveal detachment(FD), foveoschisis(FS)and lamellar macular hole(LMH). Based on the central foveal thickness(CFT)at baseline(M0), eyes with FD were classified into two subgroups: extensive FD and limited FD. Outcomes included best-corrected visual acuity(BCVA), CFT, posterior staphyloma height(PSH), the presence of epiretinal membrane(ERM)and ILM detachment. Risk factors for BCVA at 6mo after vitrectomy(M6)were analyzed using linear regression.RESULTS: At M0, ERM was highly present in eyes with LMH(rs=0.28, P<0.001). Eyes with FD and FS were characterized by higher incidence of ILM detachment(rs=-0.25, P<0.001). After vitrectomy, CFT and BCVA significantly improved in all eyes(P<0.001). Eyes with extensive FD were characterized by a thicker CFT(rs=0.56, P<0.001), a lower incidence of ILM detachment(rs=-0.25, P=0.034)and a thicker nasal PSH(rs=0.27, P=0.024)than eyes with limited FD. Eyes with extensive FD were associated with a worse BCVA at M0(P=0.013)and M6(P=0.030)than eyes with limited FD. Extensive FD(β=-0.295, P=0.042)and BCVA at M0(β=0.669, P<0.001)were risk factors for a worse BCVA at M6.CONCLUSION: There are several pathogenetic mechanisms in MTM. ILM detachment may exert a dominant role in the development of FD and FS, while ERM may have a role in LMH. Vitrectomy combined with ILM peeling improved functional and anatomical outcomes in MTM patients. Eyes with extensive FD may carry a poor prognosis.
ABSTRACT
Objective@#This small case series demonstrated pars plana vitrectomy and silicone tamponade without internal limiting membrane (ILM) peeling to be a simple, safe, and effective surgical technique for the treatment of myopic traction maculopathy (MTM).@*Methods@#This is a small case series consisting of 3 eyes with MTM. In all eyes, pars plana vitrectomy with silicone oil tamponade was performed by a single vitreoretinal surgeon. Functional and anatomic outcomes are reported.@*Results@#All 3 eyes had improved visual acuity with no noted short-term complications such as iatrogenic macular hole and retinal detachment. Although foveoschisis was only partly anatomically resolved in 2 out of the 3 cases, functional outcome, in terms of visual acuity at last visit, was satisfactory.@*Conclusion@#Vitrectomy with silicone oil tamponade without ILM peeling is a simple, effective, and safe optional surgical technique to treat MTM.
ABSTRACT
Myopic traction maculopathy (MTM) is a general term for multiple pathological changes such as myopic retinoschisis (MRS), macular hole (MH), and macular detachment (MD) in highly myopic eyes.The new MTM classification methods based on optical coherence tomography, the size and the location of the outer MRS, the relationship of MTM with posterior staphyloma, occurrence of MH and MD deepen the understanding of the disease and effectively assess the condition and prognosis of the disease.The pathogenesis of MTM may be related to the perpendicular and tangential traction produced by vitreoretinal adhesion, internal limiting membrane, and the posterior staphyloma.In the natural course of MTM, the morphology and visual function of most patients with MRS remain stable, and the progression of MRS is related to the severity of schisis and damage to the outer retinal microstructure.Surgical treatment is effective for advanced MTM with significantly impaired visual function.Vitrectomy is the main treatment method for MTM.Macular buckling or combined surgery can be chosen for MRS with MH and/or MD, and posterior scleral reinforcement is also an option for the treatment of MTM with long axial length, posterior staphyloma and poor results of vitrectomy to achieve the goal of relieving internal and external traction and repositioning the retina.The effectiveness of the surgery is also related to a variety of factors.Enzymatic vitreolysis and scleral cross-linking techniques have also provided new ideas for the treatment of MTM.This article summarized the clinical features and treatment strategies of MTM to guide its diagnosis and treatment.
ABSTRACT
High myopia is a disease with a high incidence rate and an increasing trend, which could lead to irreversible visual impairment worldwide. Myopia traction maculopathy (MTM), belonging to one of the pathological changes of high myopia, could cause vision damage and even blindness in patients. Recently, a new classification of MTM based on optical coherence tomography can effectively evaluate the condition of patients and is helpful for the diagnosis and treatment of MTM. Moreover, the improvement of internal limiting membrane peeling method and the innovation of macular buckle material provide new ideas for the treatment of MTM based on traditional surgery. New treatment such as vitreal traction release laser surgery, enzymatic vitreolysis and posterior scleral crosslinking have gained increasing attention. By combining these new treatments with artificial intelligence, 3D printing technology and advanced vitrectomy equipment, it is hoped that a safer and more effective treatment for MTM will be found in the future.

ABSTRACT
Pathological myopia, characterized by progressive elongation of the axial length and formation of posterior staphyloma, is accompanied by chorioretinal irreversible degeneration. It is also the focus and biggest challenge of myopia control and blindness prevention. For managing progressive early-onset pathologic myopia and myopic traction maculopathy, episcleral pressurization of macula is a practical option. It can be divided into posterior scleral reinforcement surgery and macular buckling surgery according to the presence or absence of operative top pressure ridge after surgery, both of which are different in terms of implanted materials, procedures and indications. The implanted materials, procedures and indications are different between the two. Under the background of soaring prevalence of myopia, it is necessary to modify and cautiously popularize the techniques of episcleral pressurization of macula to provide high level clinical evidence for management of pathological myopia.

Since its introduction by Charles L. Schepens, macular buckle (MB) surgery has evolved over the past 60 years. Optical coherence tomography (OCT) has given a paradigm shift to the understanding of myopic macula, thereby helping in objective evaluation of the various manifestation of traction maculopathy. Staphyloma evaluation by ultrasound, wide-field fundus photography, and MRI scans along with OCT has led to the resurgence of MB surgery in the treatment of myopic traction maculopathy (MTM). Various surgical techniques with different buckle materials are being performed with encouraging anatomical and functional success rates. This article reviews the literature to explain the current concept of MB surgery based on its evolution, different kinds of buckle materials, rationale for planning MB surgery, and different surgical techniques for the management of MTM.
