玻璃体切割联合内界膜剥除术治疗顽固性糖尿病黄斑水肿

目的：观察玻璃体切割术(PPV)联合内界膜(ILM)剥除术治疗顽固性糖尿病黄斑水肿的临床疗效。

方法：回顾性分析顽固性糖尿病黄斑水肿并行PPV联合ILM剥除术患者56例56眼,根据有无后极部玻璃体后脱离分为A组(无玻璃体后脱离,35例35眼)和B组(有玻璃体后脱离,21例21眼)。对比分析手术前及手术后1、3、6mo时患眼最佳矫正视力(BCVA)、黄斑中心视网膜厚度(CMT)变化情况。

结果：A组手术后1、3、6mo平均CMT和BCVA与手术前比较均有差异(P<0.05)。B组手术后1、3、6mo平均BCVA与手术前比较均无差异(P>0.05); 手术后1mo平均CMT与手术前比较有差异(P<0.05),术后3、6mo平均CMT与手术前比较均无差异(P>0.05)。术后1、3、6mo,两组CMT、BCVA比较均有差异(P<0.05)。

结论：PPV联合ILM剥除术能有效治疗无玻璃体后脱离的顽固性糖尿病黄斑水肿,提高患者视力; 但当患者玻璃体已经后脱离且没有牵拉时,PPV联合ILM剥除术治疗效果不佳。     

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 insigni?cant 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.

Multilayered inverted internal limiting membrane flap technique versus standard internal limiting membrane peeling for large macular holes: A comparative study

Purpose:To evaluate the outcome of vitrectomy with multilayered inverted internal limiting membrane flap technique (ML-IILM) versus vitrectomy with standard ILM peeling for large macular holes in terms of visual acuity and anatomical closure.Methods:A hospital-based, prospective, randomized, interventional study was conducted during three calendar years with a total 150 eyes (75 in each group) in two groups—vitrectomy with ILM peeling (Group A) and vitrectomy with ML-IILM flap technique (Group B) after informed consent of study participants who met the inclusion criteria.Results:The mean minimum and maximum diameter of macular hole did not differ statistically in both the groups. Macular hole index had no significant difference between both groups Pre-operative visual acuity was not statistically significantly different between the two groups. During follow-up, best corrected visual acuity (BCVA) at 1 month, 3 months, 6 months, and 12 months was significantly better in Group B (0.12 ± 0.07 at 1 month, 0.14 ± 0.10 at 3 months, 0.18 ± 0.11 at 6 months, and 0.19 ± 0.12 at 12 months) compared to Group A (0.20 ± 0.11 at 1 month, 0.22 ± 0.13 at 3 months, 0.30 ± 0.12 at 6 months, and 0.31 ± 0.14 at 12 months) (P = 0.001 for each). Type 1 anatomical closure (flattening of cuff and opposition of edges of hole) was achieved in 78.66% (59/75) cases in Group A and 93.33% (70/75) cases in Group B (P 0.0016).Conclusion:Vitrectomy with multilayered inverted ILM flap technique had significantly higher anatomical closure and better visual outcome than vitrectomy with standard ILM peeling.     

Comparative evaluation of vitrectomy and dye-enhanced ILM peel with grid laser in diffuse diabetic macular edema

Background The purpose of this study is to compare the effectiveness of pars plana vitrectomy (PPV) and dye-enhanced peeling of the internal limiting membrane (ILM) with modified grid laser photocoagulation in patients with diffuse diabetic macular edema and to determine if any correlation exists between improvement in visual acuity (functional improvement) and reduction in foveal thickness and macular volume (anatomical improvement). Design This is a randomized, prospective, comparative, interventional study. Method In this study 24 eyes of 24 patients with metabolically stable diabetes and with diffuse diabetic macular edema were evaluated. The patients were randomized to either pars plana vitrectomy with removal of ILM which was done in 12 eyes (ILM group) and modified grid laser photocoagulation carried out in the remaining 12 eyes (laser group). Main outcome measures were (1) the postoperative visual acuity in the form of ETDRS log MAR values, (2) foveal thickness and (3) macular volume as measured by optical coherence tomography. The correlation between improvement in visual acuity and the reduction of foveal thickness and macular volume in both the groups were also evaluated. The results were all subjected to statistical analysis. Results The ETDRS log MAR visual acuity difference between the two groups at the end of 6 months was not clinically significant (P = 0.525). However, foveal thickness and macular volume decreased significantly more in the ILM group compared to the laser group (P = 0.001, P < 0.001, Mann Whitney U test). There was no correlation between the improvement in visual acuity and the reduction of foveal thickness (r = −0.158, P = 0.6) (ILM group), r = −0.155, P = 0.7) (laser group) in both groups. Conclusions PPV with ILM peeling was shown to be beneficial by inducing a statistically significant reduction of macular thickness and macular volume. Visual acuity also demonstrated a trend towards improvement in both the ILM peel group and the grid laser group; however, the comparative VA outcome analysis between the two groups was not significantly different. Besides, there was also no correlation between the reductions of foveal thickness and macular volume with the improvement in visual acuity in either of the groups.     

玻璃体切割联合内界膜剥离术治疗特发性黄斑裂孔

目的评价玻璃体切割联合内界膜剥离术治疗特发性黄斑裂孔的临床疗效。方法采用玻璃体切割联合内界膜剥离术治疗特发性黄斑裂孔17例17眼,对患者术前术后视功能、术后黄斑裂孔闭合及手术主要并发症等进行检查和随访。结果本组17眼均成功剥离内界膜。随访5～24个月,其中13眼黄斑裂孔完全闭合,4眼裂孔直径缩小,裂孔封闭成功率为76.47%;17眼中14眼视力提高,视力提高率为82.35%;视物变形等症状也有明显改善。并发症主要有术中毛细血管性出血、术后一过性高眼压及晶状体后囊下混浊。结论玻璃体切割联合内界膜剥离术可有效封闭特发性黄斑裂孔,提高视功能。     

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 (both P<0.05). Mean CRT values were significantly lower than preoperative values in both groups (all P<0.05). The TMV was lower, except for at 1mo, in the single treatment group (P<0.05). At 12mo, the proportion of eyes with edema that had CRT more than 350 μm was significantly lower than before surgery (χ²=10.757, 7.226, respectively; 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 (P>0.05). 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 accelerated the absorption of ME, improved vision, reduced the postoperative CRT and TMV, and reduced the recurrence rate of postoperative ME.

结论：MHRD患者应用PPV联合ILMP术后恢复情况好,并发症发生率低,能更好地提高患者视网膜复位效果。     

Triamcinolone versus inner-limiting membrane peeling in persistent diabetic macular edema (TIME study): design issues and implications

Aim Treatment options for persistent diabetic macular edema remain disappointing. ILM peeling and intravitreal triamcinolone have been successfully used in several case series; however, there is no evidence that one of these options is superior for specific groups of patients. The triamcinolone versus ILM peeling in diabetic macular edema study (TIME-study) is designed to investigate the efficacy of these two treatments in patients with persistent diabetic macular edema. Methods Patients with persistent diabetic macular edema are randomised to either the control group (no treatment), ppV + ILM peeling, or triamcinolone (4 mg) injection. One hundred thirty-five patients are to be recruited per group and followed-up for one year. The main endpoints are defined as change in visual acuity (VA) at 12 months compared to baseline and the change in retinal thickness after 3 months follow-up. Secondary endpoints include differences in the functional success and anatomical success and the effect of the treatment on the patient’s quality of life. Twelve institutions (28 surgeons) in 3 European countries agreed to contribute to the study. Results The design issues and implications of the study are described. Conclusions The TIME study is the first randomised prospective clinical trial to investigate the effectiveness of the two treatment methods. The results of this study should enable physicians to improve therapy and to select cases according to the most promising treatment option.

Assessment of macular function by multifocal electroretinogram in diabetic macular edema before and after vitrectomy

The purpose of this study was to assess the effects of vitrectomy on retinal function in macular and paramacualr areas in patients with diabetic macular edema (DME). Ten eyes of 9 patients with successful vitrectomy for DME were evaluated by multifocal electroretinogram (mfERG), optical coherence tomography (OCT), and visual acuity preoperatively and 1, 2, 3, 4, 5 and 6 months postoperatively. Compared with pretreatment values, the response of the positive wave (P1) in macular and paramacular areas tended to decrease in latency from the second postoperative month, and increase in amplitude at the third postoperative month. There was no significant change in response of the negative wave (N1). The tendency in the change of macular function is coincident with that of macular morphology. Therefore, The multifocal ERG may provide objective criteria for the functional evaluation of DME before and after vitrectomy.

玻璃体切除黄斑前膜剥除联合内界膜剥除对特发性黄斑前膜患者疗效的影响

目的：分析玻璃体切除黄斑前膜剥除术联合与不联合内界膜(ILM)剥除对特发性黄斑前膜(IMEM)患者脉络膜厚度、视力和视物变形的影响。

方法：前瞻性研究。收集2016-01/2020-01在本院诊治的IMEM患者88例88眼,按随机数字表法分两组：观察组44眼接受玻璃体切除黄斑前膜剥除术联合内界膜剥除治疗,对照组44眼仅接受玻璃体切除黄斑前膜剥除术治疗。比较两组患者手术前后脉络膜厚度、视力和视物变形、黄斑中心凹厚度(CMT)、椭圆体区连续性(EZ)及并发症。

结果：与术前比较,两组患者术后3、6mo时的黄斑中心凹脉络膜厚度(SFCT)、距黄斑中心凹鼻侧1 000μm处脉络膜厚度(NFCT)及距黄斑中心凹颞侧1 000μm处脉络膜厚度(TFCT)均明显下降(P<0.05),但两组间比较无差异(P>0.05); 与术前比较,两组患者最佳矫正视力(BCVA)改善,光敏感度(MS)上升,观察组患者黄斑暗点数(SP)上升,对照组患者SP下降,观察组术后1、3、6mo时的MS明显低于对照组,SP高于对照组(均P<0.05); 与术前比较,两组患者术后3、6mo时的水平和平均M评分较术前均明显下降(均P<0.05),但组间无差异(P>0.05); 两组术后1、3、6mo时的CMT较术前均明显下降,观察组术后3、6mo时的CMT均高于对照组(均P<0.05),EZ连续比例及并发症发生率组间比较均无差异(P>0.05)。

结论：玻璃体切除黄斑前膜剥除治疗IMEM时,无论是否联合ILM剥除均可取得良好的视力并改善视物变形,且对脉络膜厚度的影响及安全性相当; 但联合ILM剥除具更低的光敏感度和更高的暗点数,术后CMT更厚,并未体现出显著优越性。

Purpose: To report the surgical outcome of pars plana vitrectomy (PPV) without internal limiting membrane (ILM) peeling in three highly myopic patients with macular retinoschisis and associated posterior staphyloma. Methods: We report three highly myopic patients with macular retinoschisis and foveal detachment who underwent simple PPV without ILM peeling, with long‐acting gas tamponade. Main outcome evaluations included best corrected visual acuity, biomicroscopic appearance and optical coherence tomography findings. Results: Pars plana vitrectomy without ILM peeling resulted in anatomic and functional improvement in all three operated eyes for follow‐up periods of ≥ 12 months. Conclusions: Pars plana vitrectomy without ILM peeling is effective for treating macular retinoschisis and foveal detachment in highly myopic eyes with posterior staphyloma. Visual and anatomic outcomes are comparable with those in previous studies in which ILM removal was performed.
