Clinical observation of vitrectomy combined with endolaser photocoagulation at the edge of posterior scleral staphyloma for macular hole retinal detachment in high myopia

AIM: To observe the clinical effect of pars plana vitrectomy(PPV) and silicone oil filling surgery combined with intraoperative posterior scleral staphyloma(PS) marginal retinal photocoagulation in the treatment of high myopic macular hole retinal detachment(MHRD) with PS.METHODS: This was a retrospective clinical study. From May 2017 to March 2020, 62 MHRD patients with PS(62 eyes) were enrolled in the study. Patients were divided into 23 G PPV combined with PS marginal retina intraoperative photocoagulation group(combined group) and conventional surgery group(conventional group), with 31 eyes in each. Triamcinolone acetonide and indocyanine green were used to remove the epiretinal membrane and the posterior macular inner limiting membrane(ILM). In the combined group, 2 to 3 rows of retinal photocoagulation were performed on the edge of the PS. The patients were followed up for an average of 8.34±3.21 mo. The first retinal reattachment rate, macular hole closure rate, Duration of silicone oil tamponade, best corrected visual acuity(BCVA) and average number of operations were observed and compared between the two groups.RESULTS: The first retinal reattachment rates of the eyes in the combined group and the conventional group were 96.7%(29/31) and 67.7%(21/31), respectively(χ~2=6.613, P=0.010). The macular hole closure rates in the combined group and the conventional group were 74.2%(23/31) and 67.7%(21/31), respectively(χ~2=0.128, P=0.721). The Duration of silicone oil tamponade of the patients in the combined group was lower than that of the routine group(t=-41.962, P≤0.001). Postoperative log MAR BCVA values of patients in the combined group and the conventional group were 1.27±0.12 and 1.26±0.11, compared with the log MAR BCVA before surgery, each group was improved(t=19.947, t=-19.517, P≤0.001, P≤0.001). There was no significant difference in the log MAR BCVA between the eyes of the two groups(t=-0.394, P=0.695). The average numbers of operations on the eyes in the conventional group and the combined group were 2.39±0.62 and 2.06±0.25 times, the combined group had fewer operations on average(t=-2.705, P=0.009). CONCLUSION: Intraoperative PPV treatment of MHRD with PS combined with PS marginal endolaser photocoagulation can effectively increase the rate of retinal reattachment after the first operation, reduce the number of repeated operations, and reduce the postoperative duration of silicone oil tamponade.

Surgical Management of Retinal Detachment Resulting from Macular Hole in a Setting of High Myopia

Purpose:To evaluate the anatomical and visual outcomes of pars plana vitrectomy (PPV) with internal limiting membrane (ILM).peeling and use of retinal tamponade for retinal detachments resulting from macular hole (MHRD) in highly myopic eyes. Methods:.Twenty-nine highly myopic patients.(29 eyes) underwent PPV with ILM peeling and retinal tamponade for MHRD were enrolled. Demographics and best-corrected visual acuity.(BCVA).were measured preoperatively and at final follow-up. Anatomical success and macular hole closure were analyzed. Results:.Patients' mean age of patients was 58.7±10.6 years, mean follow-up was 11.7±7.4 months. Twenty three eyes (23/26,88.5%)undergoing primary PPV combined with ILM peeling had successful initial retinal reattachment, including 19 eyes (19/19, 100%) with silicone oil tamponade and in 4 eyes (4/7,57.1%).with sulfur hexafluoride.(C3F8).tamponade. Overall anatomical success was achieved in 27 eyes (27/29, 93.1%)..The macular hole closure was observed in 17 eyes (17/26, 65.4%) with final anatomical success. Compared to preoperative BCVA,.the mean postoperative BCVA in the eyes with anatomical success was significantly improved (P = 0.007, Wilcoxon signed rank test). Conclusion:.As a primary or secondary procedure,.PPV combined with ILM peeling and usage of retinal tamponade serves as an effective method for MHRD in highly myopic eyes.

Amniotic membrane for covering high myopic macular hole associated with retinal detachment following failed primary surgery

AIM:To evaluate the therapeutic effect of amniotic membrane(AM)for covering high myopic macular hole associated with retinal detachment following failed primary surgery.METHODS:Seventeen eyes of 17 patients whose axial length was more than 29 mm suffered from macular hole(MH)or MH associated with retinal detachment(RD),and had previously surgery of pars plana vitrectomy(PPV)with internal limiting membrane(ILM)peeling and silicone oil(SO)tamponade.Half a year after the surgery,optical coherence tomography(OCT)showed that MH did not heal in all 17 eyes and RD was still maintained in 13 eyes of these 17 eyes.We performed SO removal combined with AM covering on macular area and C3 F8 tamponade,and phacoemulsification combined with intraocular lens implantation simultaneously cataract eyes.We followed up these patients for one year.RESULTS:In all 17 eyes,SO was removed successfully,MHs were healed and RDs were reattached.One eye(5.89%,1/17)had AM shifted half a month after surgery and underwent a second surgery to adjust the position of the AM and supplement C3 F8.After surgery,the visual acuity(VA)improved in 15 eyes(88.24%,15/17),no change in two eyes(11.76%,2/17).No serious complications occurred in all eyes.CONCLUSION:AM covering is helpful to rescue the previous failure surgery of high myopic MH.

Vitrectomy with internal limiting membrane peeling versus its flap insertion for macular hole in high myopia: a Meta-analysis

AIM: To compare the anatomic and functional outcomes between vitrectomy with internal limiting membrane(ILM) peeling and internal ILM flap insertion technique for high myopia macular hole(MH).METHODS: Pub Med, Cochrane Library, EMBASE, and CNKI were systematically searched, and all studies involved MH were included. The closure rate of MH and the postoperative best-corrected visual acuity(BCVA) at 6 mo after the initial surgery were the primary measures. All statistical tests were performed in Review Manager 5.3.RESULTS: Five studies that included 151 eyes of 151 patients were finally included, all of which were retrospectively comparative studies. Between the pars plana vitrectomy(PPV) with ILM peeling surgery and the ILM insertion technique, the latter had significantly better efficacy with respect to the closure rate of MH(OR=21.32, 95%CI=7.25-62.67, P<0.001);However, regarding BCVA at 6 mo after the initial surgery in MH, there was no statistical significance between the groups(OR=-0.04, 95%CI=-0.22-0.14, P=0.66). In addition, regarding the rate of retinal reattachment after the initial surgery, the two different methods were not significantly different(OR=2.22, 95%CI=0.34-14.32, P=0.4).CONCLUSION: Both ILM peeling and ILM insertion technique could significantly improve anatomic outcomes of MH in high myopia with or without retinal detachment(RD), and anatomic outcomes are more effective. However, there is no statistical significance in BCVA at 6 mo after the initial surgery in MH, or in the rate of retinal reattachment after the first surgery, between the two methods.

Episcleral macular buckling for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole

A silicone sponge sutured directly across the macular region was performed on the silicone oil filled eyes. Silicone oil was removed no sooner than 1 month post- EMB. The duration of follow -up time after removal of silicone oil was more than 3 months.RESULTS: Retinas of five eyes were all reattached at the last follow-up. The postoperative vision ranged from counting fingers to 0.08.CONCLUSION: Anatomical results improved after EBM for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole, which was not evident for visual outcome.

CHARACTERISTICS OF MULTIFOCAL ELECTRORETINOGRAM IN THE FELLOW EYES OF PATIENTS WITH HIGH MYOPIA WITH RETINAL DETACHMENT

Objective To observe the changes on multifocal electroretinography （MfERG） in the fellow eyes of patients with high myopia without fundus lesions and rhegmatogenous retinal detachment （RRD）. Methods MfERG was performed in 66 patients （ 66 eyes） which were grouped into ： emmetropes （ n = 22 ） as the control eye ; high myopes without fundus lesions （ corrected visual acuity ≥ 1. 0, n = 15 ） ; and fellow eyes of high myopics with RRD （n = 29 ）. The first-order kernels N1, P1, N2 response density and latency were analyzed. Results When compared with the emmetropes group, the high myopes group had significantly reduced N1 , PI , and N2 wave response densities in rings 1 to 6 （ P 〈 0. 05 ）, delayed N1 wave latency in rings 3 to 6, and P1 wave latency in rings 3 to 5 （ P 〈 0. 05 ）. The fellow eyes group had significantly reduced N1, P1, and N2 wave response densities in rings 1 to 6 and significantly delayed N1 and P1 wave latencies in rings 3 to 6 （ P 〈0. 05） compared with the emmetropes group. Compared with the high myopes group, P1 wave response densities in rings 1 to 6, N1 wave response densities in rings 1,3, 4, and 6, and N2 wave response density in ring 1 were significantly decreased in the fellow eyes group （ P 〈 0. 05 ） ; whereas there were no significant differences in latencies between the two groups （P 〉0.05）. Conclusion MfERG can sensitively assess the early changes in visual function in fellow eyes in patients with RRD.

Surgical Treatment for the Proliferative Retinal Detachment Associated with Macular Hole in the Morning Glory Syndrome

Purpose: To evaluate the efficacy of vitrectomy with peripapillary photocoagulation and silicone oil tamponade for the proliferative retinal detachment associated with macular hole in children with morning glory syndrome. Methods: Eight children with morning glory syndrome (mean age 8.0±2.8 years; range 5～13 years) were included; all patients had unilateral eye disease and were initially misdiagnosed as having bilateral squint or amblyopia, with best corrected visual acuity <6/60. Five patients could not cooperate with the fundus examination and one patient had lens opacities.B-ultrasound confirmed that all eight patients had retinal detachment and optic disc dysplasia.All patients underwent standard 3-port pars plana vitrectomy surgery . (20G for three cases and 23G for five cases).At surgery,all patients were confirmed to have morning glory syndrome,macular hole, and proliferative retinal detachment;.two cases had a funnel shaped bulge. All the retinal detachments involved the macular area, and macular hole was detected in the abnormal expansion excavation of the optic disk. The epiretinal membrane and subretinal membrane were completely removed during surgery. Combined photocoagulation in the abnormal expansion excavation of the optic disk, and silicone oil tamponade were also performed. Results:All eyes achieved anatomical resolution of retinal detachment.After follow-ups ranging from eight months to four years,the visual function for all patients was improved by postoperative refractive correction associated with vision training. Best corrected visual acuity was 6/600 to 6/30 at the final follow-up, no retinal detachment recurred, and no silicone oil fluid entered the subretinal space. The silicone oil was successfully removed postoperatively after a mean of 1.5 years. Conclusion:Vitrectomy with peripapillary photocoagulation and silicone oil tamponade is effective in treating the proliferative retinal detachment associated with macular hole in children with morning glory syndrome.

AIM:To investigate the clinical characteristics,treatment methods and outcomes of rhegmatogenous retinal detachment(RRD)in highly myopic eyes with implantable collamer lens(ICL).METHODS:High myopia patients who received treatment for nontraumatic RRD after ICL implantation surgery at the Retinal Department of Zhongshan Ophthalmic Center from Jan 2018 to Dec 2022 were reviewed.Comprehensive ophthalmologic examinations including visual acuity measurement and digital fundus photography were performed in each patient.RESULTS:A total of nine RRD eyes from nine patients who received V4c-ICL implantation were included.The mean time from ICL implantation surgery to the diagnosis of RRD was 32.44±22.56mo(range,1-60mo).At the initial visit for RRD,giant retinal tear(GRT),horseshoe tear,simple round hole,and horseshoe tear combined with round hole were detected in 3,3,2,and 1 eye(s),respectively,with maculaoff in eyes.Eight patients received surgical treatment,and one patient was treated by retinal laser photocoagulation alone.The ICL was preserved in 7 eyes.At the last followup,the mean best corrected visual acuity(BCVA)improved significantly from 1.76±1.06 logMAR at presentation to 0.81±1.01 logMAR(P=0.035),and no case of recurrent retinal detachment was found.CONCLUSION:The morphological presentation of retinal breaks is diverse in this study.The ICL can be preserved in most cases during the course of retinal detachment repair surgery in our data,companied with acceptable visual and anatomical outcomes.

Posterior vitreous cortex contributes to macular hole in highly myopic eyes with retinal detachment

Background It was well known that tangential vitreoretinal traction and epiretinal membrane play important roles during the formation of macular hole （MH） associated with retinal detachment （RD） in highly myopic eyes. But it was not clear about the correlations between anteroposterior traction, posterior vitreous cortex （PVC） and MH-RD. The vitreous status in highly myopic eyes were analyzed to explore the effect of PVC in the role of MH-RD formation. Methods Sixteen consecutive highly myopic eyes with RD due to MH were retrospectively analyzed from January 2009 to April 2009. The preoperative examinations for detecting posterior vitreous detachment （PVD） and vitreoretinal traction included B-mode ultrasonography and optical coherence tomography （OCT）. The residual PVC and PVD were confirmed intraoperatively during triamcinolone acetonide （TA） assisted vitrectomy. Results Under ultrasonography, the preoperative PVD patterns were stratified as： complete PVD in three （19%） eyes, partial PVD in eight （50%） eyes, and no PVD in five （31%） eyes. OCT confirmed vitreoretinal traction and no complete PVD in 10 （63%） eyes, including anteroposterior traction in four eyes and tangential traction in six eyes. During TA-assisted vitrectomy, it was confirmed that no complete PVD existed in 16 eyes, including six eyes （38%） finally diagnosed of partial PVD, and five （31%） eyes with vitreoschisis. Anteroposterior vitreoretinal traction around MH is always in conjunction with partial PVD （67%）, and high proportion （80%） of vitreoschisis is associated with tangential vitreoretinal traction. Comparing with the precision of TA staining of PVD diagnosis, the coincidence rate of ultrasonography was 69% （P=0.02）, and that of OCT was 63% （P 〈0.01）. Conclusions The residual PVC due to partial PVD or vitreoschisis may cause the anteroposterior or tangential traction of macular area, which contributes to the formation of MH and subsequent RD in highly myopic eyes. And it is necessary to realize the vitreoretinal relationship and assess the status of PVC synthetically for surgery by combined ultrasonography and OCT preoperatively and TA staining intraoperatively.

背景高度近视黄斑裂孔视网膜脱离（MHRD）可造成严重的视力下降，经睫状体平坦部的玻璃体切割术联合眼内填充术已应用于该病的临床治疗，目前常用的眼内填充物包括硅油及可膨胀性气体C3F8，两种填充物的效果比较仍缺少相关研究证据。目的评价玻璃体切割联合硅油填充与C3F8填充治疗高度近视黄斑裂孔视网膜脱离的手术效果。方法采用回顾性病例对照设计。对采用玻璃体切割联合眼内填充术治疗的51例高度近视MHRD患者，根据术中眼内填充物的不同将患者分为硅油填充组和C3F8填充组，两组患者基线资料一致。对两组术眼术后的最佳矫正视力（BCVA）、视网膜复位率、黄斑裂孔闭合情况及视网膜脱离复发率进行分析和比较。结果两组患者术前视力差异无统计学意义（U=266．000，P=0．286），基线视力一致，术中不同眼内填充物治疗后视力差异亦无统计学意义（U=205．000，P=0．029）；应用硅油填充及C3F8填充患者BCVA术后与术前相比均有显著提高，差异均有统计学意义（Z=-2．729，P=0．006；Z=-3．273，P=0．001），两组患者术后视网膜脱离发生率及黄斑裂孔解剖闭合率差异均无统计学意义（P=0．894、1．000）。患者除自内障外无其他并发症发生。结论应用C3F8填充治疗高度近视MHRD与硅油填充治疗效果相同，且均安全、有效。

玻璃体切割联合黄斑加固术治疗高度近视合并黄斑裂孔性视网膜脱离

目的观察玻璃体切割联合黄斑加固术治疗高度近视合并黄斑裂孔性视网膜脱离患者术后视网膜的解剖复位率和黄斑裂孔的闭合率。方法收集自2012年1月至2014年12月在我院手术的高度近视合并黄斑裂孔性视网膜脱离的患者64例(64眼),根据手术方式不同分成2组:一组行单纯玻璃体切割术为单纯玻切组,另一组行玻璃体切割联合黄斑加固术为联合手术组,观察两组视力及视网膜解剖复位率和黄斑裂孔闭合率。结果 64例64眼中,单纯玻切组36例,术前视力平均为0.90 log MAR,术后平均为0.41 log MAR;联合手术组28例,术前视力平均为0.89 log MAR,术后平均为0.62 log MAR;两组术前视力差异无统计学意义,术后差异有统计学意义(P=0.04)。两组患者术后视网膜复位均率为100%;联合手术组的黄斑裂孔闭合率较高,为92.9%,单纯玻切组为41.7%,两组比较差异有统计学意义(P=0.02)。结论在高度近视合并黄斑裂孔性视网膜脱离的患者中,联合行黄斑加固术较单纯玻璃体切割术患者的黄斑裂孔闭合率要高。
