Effects of vitrectomy combined with internal limiting membrane peeling in patients with diabetic macular edema

BACKGROUND Diabetic macular edema(DME),a chronic microvascular complication of diabetes,is a leading cause of visual impairment and blindness.Pars plana vitrectomy(PPV)can restore the normal macular structure and reduce macular edema,whereas internal limiting membrane(ILM)peeling is used to treat tractional macular diseases.Despite the advantages,there is limited research on the combined effects of PPV with ILM peeling.AIM To observe the effects of PPV combined with ILM peeling on postoperative central macular thickness(CMT),best-corrected visual acuity(BCVA),cystoid macular edema(CME)volume,and complications in patients with DME.METHODS Eighty-one patients(92 eyes)diagnosed with DME at the Beijing Shanqu Liangxiang Hospital between January and December 2022 were randomly divided to undergo PPV alone(control group:41 patients,47 eyes)or PPV+ILM peeling(stripping group:40 patients,45 eyes);a single surgeon performed all surgeries.The two groups were compared preoperatively and 1 and 3 months postoperatively.RESULTS Preoperatively,both groups had comparable values of CMT,BCVA,and CME volume(P>0.05).After surgery(both 1 and 3 months),both groups showed significant reductions in CMT,BCVA,and CME volume compared to preoperative levels,with the stripping group showing more significant reductions compared to the control group(P<0.05).Further repeated-measures ANOVA analysis for within-group differences revealed significant effects of group and time,and interaction effects for CMT,BCVA,and CME volume(P<0.05).There were no significant differences in the incidence of complications between the groups(retinal detachment:control=2,stripping=1;endophthalmitis:Control=4,stripping=1;no cases of secondary glaucoma or macular holes;χ^(2)=0.296,P=0.587).CONCLUSION PPV with ILM peeling can significantly improve the visual acuity of patients with DME,reduce CMT,and improve CME with fewer complications.

Efficacy and safety of vitrectomy with internal limiting membrane peeling for diabetic macular edema: a Meta-analysis

AIM： To evaluate the efficacy and safety of vitrectomy with internal limiting membrane（ILM） peeling for diabetic macular edema（DME）. METHODS： The PubMed, Embase, Web of Science, Cochrane, SionMed, ClinicalTrials.gov, CNKI databases and Wanfang databases, published until Oct. 2017, were searched to identify studies comparing the clinical outcomes following vitrectomy with and without ILM peeling, for treating DME. Pooled results were expressed as odds ratios（ORs） with corresponding 95% confidence intervals（CI） for vitrectomy with and without ILM peeling with regard to best corrected visual acuity（BCVA）, central macular thickness（CMT）, and complication incidents. RESULTS： A total of 14 studies involving 857 eyes were included of which three studies were Chinese and the rests were English literatures. Meta-analysis indicated that compared with vitrectomy alone, vitrectomy with ILM peeling could improve BCVA more obviously（OR=1.66, 95%CI： 1.12-2.46, P=0.01） and had higher rate of CMT reduction（OR=3.89, 95%CI： 1.37-11.11, P=0.01）. There were significant statistical differences between the two surgical methods for both BCVA and CMT（P〈0.05）. For the incidence of intraoperative and postoperative complications, the incidence of epiretinal membrane（ERM） was slightly lower in the ILM peeling group than the group without ILM peeling（OR=0.38, 95%CI： 0.07-2.00, P=0.25）, although insignificant statistically. Other incidences of overall complications, iatrogenic peripheral retinal break and increased intraocular pressure indicated no significant difference between two groups（OR=1.19, 95%CI： 0.82-1.73, P=0.36; OR=1.21, 95%CI： 0.66-2.21, P=0.53; OR=1.34, 95%CI： 0.75-2.40, P=0.32）. CONCLUSION： Vitrectomy is effective for DME and the effect can be improved by additional ILM peeling, especially for anatomical efficacy, without increasing the incidence of intraoperative and postoperative complications. However, it is imperative to gain more evaluation in the future due to the paucity of prospective randomized study.

Efficacy of internal limiting membrane peeling for diabetic macular edema after preoperative anti-vascular endothelial growth factor injection

AIM:To explore the efficacy of minimally invasive vitrectomy(MIV)with or without internal limiting membrane(ILM)peeling on the treatment of diabetic macular edema(DME)in proliferative diabetic retinopathy(PDR)combining with preoperative anti-vascular endothelial growth factor(anti-VEGF)injection.METHODS:Totally 132 eyes(132 patients)diagnosed PDR with DME were included between June 2015 and June 2018 in Tianjin Eye Hospital.The single MIV treatment group included 68 eyes and the MIV combined with ILM peeling group included 64 eyes.Anti-VEGF drugs were injected intravitreally 1wk before the operation and the period of follow-up was 1 to 3y.Best-corrected visual acuity(BCVA),central retinal thickness(CRT),total macular volume(TMV),macular edema(ME)severity,intraocular pressure(IOP),and complications were recorded.Prognostic factors of visual acuity following ILM peeling were analyzed.RESULTS:The BCVA was higher than preoperative values at 1,3,6,and 12mo after surgery in both groups(all P<0.05).At 6 and 12mo,the BCVA of the combined group was significantly higher than that of the MIV only group(0.52±0.23 v/s 0.64±0.29 IogMAR,P=0.011 in 6mo;0.41±0.25\/s 0.52±0.25 IogMAR,P=0.008 in 12mo).Mean CRT values postoperative were significantly lower than preoperative values in both groups from the 1^(st) month(lmo 397.65±106.18 vs 451.94±118.88 μm in MIV only group;388.88±108.68 v/s 464.36±111.53 μm in combined group;both P<0.05)and decreased gradually.The differences between the two groups were statistically significant at 3,6,and 12mo(P=0.004,0.003,0.00 respectively).The TMV was decreased from the 3^(rd) month in the single treatment group(3mo 11.14±1.66 vs 12.20±2.09 mm^(3),P<0.05).At 12mo,the proportion of eyes with edema that had CRT more than 350μm was significantly lower than before surgery(13.24%vs 77.94%in MIV only group;1.56%vs 81.25%in combined group;both P<0.05).There was no significant difference in the recurrence incidence of macular epiretinal membrane,ME,transient IOP increase,vitreous rebleeding,or traction retinal detachment between the two groups.BCVA after ILM excision was positively correlated with the CRT and ME degree before and after surgery(r=0.430,0.485,respectively;P<0.05).CONCLUSION:MIV combined with ILM peeling accelerates the absorption of ME,improves vision,reduces the postoperative CRT and TMV,and reduces the recurrence rate of postoperative ME.

Vitrectomy with residual internal limiting membrane covering and autologous blood for a secondary macular hole:A case report

BACKGROUND Myopic foveoschisis(MF)is a common complication of pathological myopia.A macular hole(MH)usually results from the natural progression of MF and is a common complication of vitrectomy.Vitrectomy combined with residual internal limiting membrane(ILM)covering and autologous blood was effective for closing a secondary MH.CASE SUMMARY A 52-year-old woman presented to our clinic with a complaint of blurred vision in the right eye for 7 years.Her best corrected visual acuity(BCVA)was 20/100,axial length was 25.79 mm and standard equivalent refractive error was-10.5 dioptres.Preoperative optical coherence tomography revealed foveoschisis in the right eye.Vitrectomy with fovea-sparing ILM peeling was performed.An MH developed and gradually expanded 5 mo after the initial vitrectomy.Vitrectomy with residual ILM covering and autologous blood was performed.The MH closed 3 wk after the second vitrectomy.CONCLUSION Fovea-sparing ILM peeling can provide residual ILM for the treatment of MH secondary to vitrectomy for MF.Vitrectomy combined with residual ILM covering and autologous blood is effective for closing secondary MH and improving BCVA.

Efficacy of Phacovitrectomy Combined with Internal Limiting Membrane Peeling for Macular Diseases

Purpose:To observe the efficacy of vitrectomy with internal limiting membrane.(ILM) peeling combined with phacoemulsification with intraocular lens.(IOL) implantation in the treatment of cataract with co-existing macular diseases.Methods:A total of 28 cataract patients (28 eyes) with coexisting macular diseases were admitted to Aier Eye Hospital between May 2008 and May 2011.The clinical characteristics were analyzed in this study.Subjects included 6 men and 22 women,aged from 56 to 77 years (mean 64 years),with duration of disease ranging from 2 to 36 months (mean 9.3 months).All patients underwent phacoemulsification with implantation of a hydrophobic acrylic IOL into the capsular bag and pars plana vitrectomy with ILM peeling.Results:Postoperatively,patients underwent 3-to 18-months of follow-up.(mean 7.2 months).Only one eye had macular hole failing to close.Normal macular structure was restored in the other 27 eyes.The presenting visual acuity and best corrected visual acuity.(BCVA) did not differ significantly (t =-1.724,P =0.096),with the BCVA in 27 eyes.(96.4%).improving by 2 lines or more.The improvement in minimum angle of resolution.(MAR).was > 0.3 in 21 eyes,≥0.1 in 6 eyes and<0.1 in 1 eye.The mean spherical equivalent.(SE) was-4.67±5.98D preoperatively and-0.38±0.69D postoperatively (t=4.157,P<0.005).Conclusion:Combined phacovitrectomy surgery is a reliable and safe procedure in the treatment of cataract complicated by macular disease.

Foveal regeneration after resolution of cystoid macular edema without and with internal limiting membrane detachment:presumed role of glial cells for foveal structure stabilization

AIM: To document with spectral-domain optical coherence tomography the morphological regeneration of the fovea after resolution of cystoid macular edema(CME) without and with internal limiting membrane(ILM) detachment and to discuss the presumed role of the glial scaffold for foveal structure stabilization. METHODS: A retrospective case series of 38 eyes of 35 patients is described. Of these, 17 eyes of 16 patients displayed foveal regeneration after resolution of CME, and 6 eyes of 6 patients displayed CME with ILM detachment. Eleven eyes of 9 patients displayed other kinds of foveal and retinal disorders associated with ILM detachment. RESULTS: The pattern of edematous cyst distribution, with or without a large cyst in the foveola and preferred location of cysts in the inner nuclear layer or Henle fiber layer(HFL), may vary between different eyes with CME or in one eye during different CME episodes. Large cysts in the foveola may be associated with a tractional elevation of the inner foveal layers and the formation of a foveoschisis in the HFL. Edematous cysts are usually not formed in the ganglion cell layer. Eyes with CME and ILM detachment display a schisis between the detached ILM and nerve fiber layer(NFL) which is traversed by Müller cell trunks. ILM detachment was also found in single eyes with myopic traction maculopathy, macular pucker, full-thickness macular holes, outer lamellar holes, and glaucomatous parapapillary retinoschisis, and in 3 eyes with Müller cell sheen dystrophy(MCSD). As observed in eyes with MCSD, cellophane maculopathy, and macular pucker, respectively, fundus light reflections can be caused by different highly reflective membranes or layers: the thickened and tightened ILM which may or may not be detached from the NFL, the NFL, or idiopathic epiretinal membranes. In eyes with short single or multiple CME episodes, the central fovea regenerated either completely, which included the disappearance of irregularities of the photoreceptor layer lines and the reformation of a fovea externa, or with remaining irregularities of the photoreceptor layer lines. CONCLUSION: The examples of a complete regeneration of the foveal morphology after transient CME show that the fovea may withstand even large tractional deformations and has a conspicuous capacity of structural regeneration as long as no cell degeneration occurs. It is suggested that the regenerative capacity depends on the integrity of the threedimensional glial scaffold for foveal structure stabilization composed of Müller cell and astrocyte processes. The glial scaffold may also maintain the retinal structure after loss of most retinal neurons as in late-stage MCSD.

Inverted internal limiting membrane flap technique for very large macular hole

AIMTo assess the anatomical and visual outcome of idiopathic macular holes greater than 1000 &#x000b5;m using the inverted internal limiting membrane flap technique.METHODSThis retrospective case series included 5 eyes of 5 patients with idiopathic macular hole with base diameter greater than 1000 &#x000b5;m who underwent inverted internal limiting membrane flap technique along with standard 23G pars plans vitrectomy with posterior hyaloid detachment and fluid gas exchange with 12%-14% perfluoropropane (C3F8). Preoperative and postoperative visual acuity and spectral domain optical coherence tomography images were evaluated. The main outcome measures were visual outcome and macular hole closure.RESULTSMean age was 63.2&#x000b1;8.4y with all 5 subjects being females. Mean duration of symptoms was 11&#x000b1;14mo with a mean postoperative follow up of 13.2&#x000b1;13mo. The mean base diameter of the macular holes was 1420&#x000b1;84.8 &#x000b5;m (1280-1480 &#x000b5;m). Type 1 closure was achieved in four out of five patients, while one patient had type 2 closure using the inverted internal limiting membrane (ILM) flap technique. Median baseline BCVA was 0.79 logMAR (Snellen’s equivalent 20/120) and median final BCVA 0.6 logMAR (Snellen’s equivalent 20/80) with mean visual improvement of approximately three lines improvement. No complications related to surgical procedure were noted.CONCLUSIONThe inverted internal limiting membrane flap technique may be promising for very large macular holes with high rate of macular closure and good visual outcome.

Free autologous internal limiting membrane transplantation in the treatment of large macular hole

We evaluated the clinical efficacy of free internal limiting membrane(ILM) flap transplantation for the treatment of large macular hole over 500 μm in 42 consecutive patients. Quantified evaluation of the post-operative macular anatomy restoration was performed by spectral-domain optical coherence tomography in the 12 mo follow-up. The results showed 41 eyes achieved successful closure(97.6%). Postoperative best corrected visual acuity, ellipsoid layer, and external limiting membrane disruption were significantly improved at all follow-up time points. The central foveal thickness was significantly higher at 1 mo. We concluded that free ILM flap transplantation proves to be effective to achieve anatomical and functional improvement for the treatment of large macular hole.

Internal limiting membrane dragging and peeling:a modified technique for macular holes closure surgery

AIM:To introduce a modified technique of internal limiting membrane(ILM)centripetal dragging and peeling to treat idiopathic macular hole(IMH)and to observe the ILM-retina adhesive forces.METHODS:Twenty-six consecutive patients with stage 3 to 4 IMH and followed up at least six months were enrolled.All patients underwent complete par plana vitrectomy,ILM dragging and peeling,fluid and gas exchange,15%C3 F8 tamponade and 2-week prone position.The best corrected visual acuity,macular hole evaluation by optical coherence tomography,and complications were evaluated.RESULTS:The mean diameter of IMH was 524±148μm(range:201-683μm),with 21 cases(80.8%)greater than 400μm.ILM dragging and peeling were successfully performed in all cases.Most of the ILM-retina adhesive forces are severe(42.3%,11/26),followed by mild(38.5%,10/26),and moderate(19.2%,5/26).The mean follow-up duration was 21.2±6.1 mo.The IMH was closed in 25(96.3%)eyes.Visual acuity(logMAR)improved significantly from 1.2±0.6 preoperatively to 0.7±0.5 postoperatively(P<0.001).CONCLUSION:Preexisting ILM-retina adhesive force is found in IMH patients.With assistance of this force,this modified technique may help to release the IMH edges and improve the closure rate of large IMH.

Displacement of the retina after idiopathic macular hole surgery with different internal limiting membrane peeling patterns

AIM:To explore retinal displacement after surgical treatment for idiopathic macular hole(IMH)with different internal limiting membrane(ILM)peeling patterns.METHODS:Totally 22 eyes from 20 patients with IMH were randomly allocated into two groups,N-T group(11 eyes)and T-N group(11 eyes).For patients in N-T group,ILM was peeled off from nasal to temporal retina.For patients in T-N group,ILM was peeled off from temporal to nasal retina.Preoperative,postoperative 1,3,and 6 mo,autofluorescence fundus images were collected for manual measurement of distances of fixed nasal(N),temporal(T),superior(S),and inferior(I)retinal points(bifurcation or crossing of retinal vessels)around the macula to the optic disc(OD).These were respectively defined as N-OD,T-OD,S-OD,and I-OD.The retinal displacement,macular holeclosure rate,and best corrected visual acuity(BCVA)were compared between the two groups after surgery.RESULTS:At postoperative 1,3,and 6 mo,the macula slipped toward the OD,manifested by the decreased T-OD,N-OD,S-OD,and I-OD(P<0.05).No significant difference was found in the T-OD,N-OD,S-OD,and I-OD between N-T group and T-N group.IMH closure rate was 100%both in N-T group and T-N group.There was no significant difference in BCVA between two groups(P<0.05).CONCLUSION:The macula slips toward the OD after successful macular hole surgery.The two different ILM peeling pattern show similar visual outcome and retinal displacement,which means ILM peeling directions are not the influencing factor of postoperative retinal displacement.

Malfunction of outer retinal barrier and choroid in the occurrence and progression of diabetic macular edema

Diabetic macular edema(DME) is the most common cause of vision loss in diabetic retinopathy,affecting 1 in 15 patients with diabetes mellitus(DM).The disruption of the inner blood-retina barrier(BRB) has been largely investigated and attributed the primary role in the pathogenesis and progression in DME, but there is increasing evidence regarding the role of outer BRB, separating the RPE from the underlying choriocapillaris,in the occurrence and evolution of DME.The development of novel imaging technologies has led to major improvement in the field of in vivo structural analysis of the macula allowing us to delve deeper into the pathogenesis of DME and expanding our vision regarding this condition.In this review we gathered the results of studies that investigated specific outer BRB optical coherence tomography parameters in patients with DM with the aim to outline the current status of its role in the pathogenesis and progression of DME and identify new research pathways contributing to the advancement of knowledge in the understanding of this condition.

玻璃体切除联合内界膜剥离术治疗高度近视黄斑裂孔的疗效

目的：比较经睫状体平坦部玻璃体切除术（pars plana vitrectomy,PPV）与PPV联合内界膜剥离术（internal limiting membrane peeling,ILMP）治疗高度近视黄斑裂孔的临床效果。方法：回顾性分析高度近视黄斑裂孔患者（伴或不伴黄斑裂孔性视网膜脱离）33例36眼的病例资料。根据手术方式不同,分为Ⅰ组和Ⅱ组。Ⅰ组15眼行玻璃体切除术（不剥离内界膜）;Ⅱ组21眼行玻璃体切除联合内界膜剥离术,术中根据患者病情不同,给予不同的辅助方式,如行硅油填充、C3F8填充、光凝、冷凝等。术后随访3-12mo,以术后最佳矫正视力（best corrected visual acuity,BCVA）、裂孔闭合及视网膜复位情况作为疗效观察指标,并将两组数据进行统计学分析。结果：Ⅰ组15眼术后最佳矫正视力（Log MAR）较术前平均提高0.167,差异有统计学意义（t=2.46,P=0.027）;Ⅱ组术后最佳矫正视力（Log MAR）较术前平均提高0.456,差异有统计学意义（t=6.753,P=0.000）;两组间术后视力提高程度比较,差异有统计学意义（t=-2.943,P=0.006）。Ⅰ组患者黄斑裂孔闭合率46.67%;Ⅱ组患者黄斑裂孔闭合率85.71%;比较两组术后裂孔闭合率,差异有统计学意义（χ^2=6.287,P=0.025）。Ⅰ组视网膜最终复位率91.67%。Ⅱ组视网膜最终复位率94.73%,比较两组患者视网膜复位情况,差异无统计学意义（χ^2=0.856,P=0.418）。结论：玻璃体切除联合内界膜剥离术可以显著提高高度近视黄斑裂孔的闭合率和术后视力,但对于视网膜的复位率较不剥膜者无明显区别。

病理性近视并发黄斑裂孔玻璃体切除联合内界膜剥除术后疗效分析

目的:探讨玻璃体切除联合内界膜剥除术治疗病理性近视黄斑裂孔的临床效果。方法:回顾性研究。选取2017-01/2019-01于我院确诊的高度近视黄斑裂孔患者18例19眼,将其分为病理性近视组(9例10眼)和非病理性近视组(9例9眼),均接受玻璃体切除联合内界膜剥除术。术后随访3~23mo,观察两组患者末次随访时最佳矫正视力(BCVA)、视物变形症状及黄斑裂孔闭合情况。结果:末次随访时,病理性近视组术后BCVA提高6眼,不变2眼,下降2眼,黄斑裂孔完全闭合7眼(70%),裸露型闭合2眼(20%),未闭合1眼(10%);非病理性近视组术后BCVA提高6眼,不变2眼,下降1眼,黄斑裂孔完全闭合8眼(88%),裸露型闭合1眼(11%)。术前两组患者眼轴长度有明显差异,眼轴长度与末次随访时黄斑裂孔闭合率呈负相关(rs=-0.477,P=0.039)。结论:玻璃体切除联合内界膜剥除术治疗高度近视黄斑裂孔可有效改善最佳矫正视力,但病理性近视患者裂孔闭合率低于非病理性近视患者。
