内界膜剥除与不剥除术治疗特发性黄斑前膜的疗效对比观察

目的 比较单纯黄斑前膜剥除术、黄斑前膜剥除联合黄斑区内界膜剥除术两种手术方法治疗特发性黄斑前膜的疗效,探讨剥除视网膜内界膜对特发性黄斑前膜患者术后影响.方法 回顾分析特发性黄斑前膜患者38只患眼的手术疗效.其中A组：黄斑前膜剥除联合内界膜剥除术18眼,B组：单纯黄斑前膜剥除术20眼.手术后随诊3个月以上,于手术前和手术后3个月时对患者行视力、MERG及OCT检查,分别对每组手术前后临床资料、两组之间临床资料进行分析.结果 手术前两组患者的年龄、视力、黄斑中心凹厚度、MERG的1环和2环P波振幅及潜时均无明显差异.手术后3个月时两组视力较手术前均明显提高,黄斑中心凹厚度较手术前明显降低,A组术后MERG的1环和2环P波振幅明显降低,但术后3个月时两组之间视力、黄斑中心凹厚度、MERG潜时差异无显著性,A组MERG的振幅比B组有明显的降低.结论 黄斑前膜剥除术是治疗特发性黄斑前膜的有效方法,内界膜剥除术在手术后短期内未显示其有效性,需进一步随访观察.     

吲哚菁绿染色与无染色视网膜内界膜剥除治疗黄斑裂孔的疗效观察

目的 观察玻璃体切割术中使用吲哚菁绿染色与无染色内界膜剥除术治疗特发性黄斑裂孔的疗效及并发症.方法 回顾性分析2006年1月至2009年3月于我院眼科行玻璃体切割联合视网膜内界膜剥除术治疗的特发性黄斑裂孔患者共计88例94眼,其中染色组55例59眼,术中使用吲哚菁绿辅助剥除内界膜;无染色组33例35眼,术中不使用染色剂.比较两组术后黄斑区视网膜最大厚度、黄斑裂孔闭合及视网膜复位情况,最佳矫正视力提高情况,剥除视网膜内界膜手术时间,mfERG变化情况.结果 随访至术后12个月时,两组患者黄斑裂孔均完全闭合、视网膜均复位.视网膜最大厚度检测结果显示,染色组与无染色组手术前后厚度的差值相比差异无统计学意义(P＞0.05).染色组术后最佳矫正视力提高2行及以上者40眼(67.8％),无染色组28眼(80.0％);染色组内界膜剥除手术时间为(235.0±9.1)s,无染色组为(168.0±7.4)s,上述两项指标两组比较差异均有统计学意义(均为P＜0.05).两组mfERG一阶函数的1环和2环P1波反应密度均较术前明显增加,与术前相比差异均有统计学意义(均为P＜0.05),但染色组增加幅度小于无染色组,两组之间比较差异有统计学意义(P＜0.05).结论 与既往应用吲哚菁绿染色行视网膜内界膜剥除术相比较,不染色行视网膜内界膜剥除术也能达到使黄斑裂孔闭合、视网膜脱离复位的目的,且视功能恢复程度更好,手术用时更少,同时避免了染色剂所致的视网膜毒性,适宜广泛应用.     

采用或不用内界膜剥除的黄斑裂孔手术

目的:在用或不用吲哚氰绿内界膜染色剥膜的情况下,比较特发性黄斑裂孔术后的解剖及视力结果。方法:对连续采用单纯注气术进行眼内填充的40眼特发性黄斑裂孔进行回顾性分析,所有手术均由一位医生完成。所有的患眼术后至少经过了6月的随访。40眼中的前22眼采用保留内界膜手术(非内界膜剥除组),后18眼采用吲哚氰绿对内界膜染色并进行内界膜剥除手术(内界膜剥除组)。结果:内界膜剥除组和非内界膜剥除组特发性黄斑裂孔解剖复位率分别为88.9%和59.1%,统计结果有显著性差异(Fisher’检验,P =0.038)。内界膜剥除组视力提高较非内界膜剥除组更为明显,平均分别提高了3.46和1.3行(t检验,P =0.0356)。多数病例术后视力提高2行或更多,在内界膜剥除组为66.7%,非内界膜剥除组为31.8%(χ2检验,P = 0.028)。然而在2组之间最终的术后logMAR BC-VA没有明显的差异(t检验,P =0.0073)。结论:根据以上研究,通过吲哚氰绿内界膜染色剥除内界膜可促进特发性黄斑裂孔解剖复位及视力的提高。在此方面进一步的研究是必要的。

Long-term outcomes of internal limiting membrane peeling with and without indocyanine green in macular hole surgery

PURPOSE: To compare the long-term anatomic closure rate and visual outcome in patients who underwent internal limiting membrane (ILM) peeling with and without indocyanine green (ICG) dye staining for idiopathic macular hole repair. DESIGN: Retrospective, nonrandomized, comparative study of consecutive case series. METHODS: A total of 190 eyes of 182 patients with idiopathic macular holes underwent macular hole repair between March 1998 and June 2003. Surgery consisted of pars plana vitrectomy, lensectomy if phakic, ILM peeling, intravitreal gas tamponade, and 1 week's face-down positioning. In the initial 94 consecutive eyes, ILM peeling was performed without adjuvants (non-ICG group). The subsequent 96 eyes underwent surgery with ICG-stained ILM peeling (ICG group), in which the ILM was stained with intravitreal application of 0.1 to 0.2 mL of 0.1% ICG solution. RESULTS: Two groups of patients had comparable clinical backgrounds preoperatively. Mean follow-up time was 30.7 months in non-ICG group and 26.2 months in ICG group. Anatomic closure of the macular hole was achieved in 99% of the cases in both groups, with both groups showing statistically significant visual improvement. There was no statistically significant difference in visual acuity between the two groups at each follow-up visit. There were also no intraoperative or postoperative complications attributed to the use of ICG. CONCLUSIONS: Long-term follow-up of patients undergoing ILM peeling for idiopathic macular hole repair shows equivalent anatomic and visual outcomes with and without the use of ICG.     

Clinical findings in macular hole surgery with indocyanine green-assisted peeling of the internal limiting membrane

PURPOSE: Indocyanine green (ICG) staining of the internal limiting membrane has facilitated ILM peeling in macular hole surgery. However, it has been reported that ICG-assisted peeling of the ILM may result in retinal damage and unfavorable functional outcome. Therefore, we analyzed our visual and anatomical results of ICG assisted macular hole surgery. METHODS: In a retrospective study the records of a consecutive series of 37 patients with full-thickness idiopathic macular holes operated with ICG-assisted ILM peeling by a single surgeon were analyzed. All patients underwent a standard three-port vitrectomy with surgically induced posterior vitreous detachment, staining of the ILM with ICG, peeling of the ILM in a circular manner around the fovea, and SF6 20% endotamponade. RESULTS: A total of 37 patients (37 eyes) were included in the study. The mean age was 69+/-7 years (range 52-81 years), and there were 26 women and 11 men. The follow-up ranged from 6 to 30 months (mean 18+/-6 months). At baseline visual acuity ranged from 20/400 to 20/40. Anatomically, 13 eyes had stage 2 holes, 21 eyes (57%) stage 3 holes, and three eyes stage 4 holes. At the postoperative visit (8-12 weeks after surgery) anatomical closure of the macular hole was achieved in 36 eyes. Visual acuity ranged between 20/400 and 20/20. At the last follow-up after initial surgery the macular hole was closed in all eyes. Visual acuity ranged from 20/200 to 20/20. CONCLUSION: In our retrospective series anatomical and functional results of macular hole surgery with ICG-assisted peeling of the ILM are satisfactory. Primary hole closure was achieved in 97% of eyes and visual acuity increased in 62% of eyes in our series.     

Does intravitreal triamcinolone acetonide-assisted peeling of the internal limiting membrane effect the outcome of macular hole surgery?

Purpose To evaluate functional and anatomical outcome of triamcinolone acetonide assisted internal limiting membrane (ILM) peeling in patients with macular hole.Methods Fifteen eyes of 15 consecutive patients were identified with stage 3 and 4 idiopathic macular holes, these undergoing triamcinolone acetonide assisted ILM peeling for macular holes. These were matched retrospectively with 15 eyes of 15 patients with stage 3 and 4 idiopathic macular holes of less than six months duration, who underwent macular hole surgery with ILM peel augmented with indocyanine green (ICG). Functional and anatomical outcomes were compared between two groups.Results There were no significant differences between the two groups with reference to demographic features of age, sex, staging of the macular holes and the proportion subsequently undergoing cataract surgery. The mean follow-up period was 6.4 months in the triamcinolone acetonide group and 7.2 months in the ICG group. The hole closure rate was 100% in both group at primary operation. The mean Snellen line change was +1.24 in the intravitreal triamcinolone group and +1.1 in the ICG group. There was a significant improvement in Snellen and Logmar visual acuity in both groups. These differences in visual outcome between the groups were not statistically significant.Conclusions Our data showed similar outcomes for patients with macular hole where ICG has been used when compared to patients where triamcinolone acetonide has been used for ILM peeling. Further study with longer follow-up and large series is warranted to assess the safety of the triamcinolone acetonide assisted ILM peeling in macular hole surgery.The authors have no commercial interest in the material used in this work.     

A comparison of outcomes after indocyanine green and trypan blue assisted internal limiting membrane peeling during macular hole surgery

AIMS: To compare the anatomical and visual outcomes of macular hole repair surgery using indocyanine green (ICG) or trypan blue (TB) staining of the internal limiting membrane (ILM). METHOD: Retrospective analysis of 37 eyes from 37 consecutive patients with stage 2, 3, and 4 idiopathic macular holes who underwent macular hole repair by one surgeon using the same technique but utilising different dyes for ILM peeling. In 19 patients ICG was used while 18 patients had TB. The anatomical and visual results in these two groups were compared. RESULTS: There were no significant differences in the demographic and macular hole characteristics of the ICG and TB groups. Macular hole closure was achieved in 91.9% of all patients of which the ICG group had an 89.5% hole closure rate and the TB group had a 94.4% hole closure rate. After excluding cases with failed hole closure and other vision affecting complications, there was no significant difference between the preoperative visual acuities in the TB and ICG groups but the postoperative visual acuities were better in the TB than the ICG group (p = 0.036). The TB group also had more Snellen lines of improvement than the ICG group (2.94 v 1.79 lines; p = 0.046). CONCLUSION: TB appears to be less toxic than ICG when used in dye assisted peeling of ILM during macular hole repair as reflected by the better visual results in the TB group of patients.

Internal limiting membrane removal in macular hole surgery for severely myopic eyes: a case-control study

AIMS: To determine the surgical outcome of indocyanine green (ICG) assisted retinal internal limiting membrane (ILM) peeling in macular hole surgery for severely myopic eyes and compare the visual and anatomical outcomes with an emmetropic control group. METHODS: 10 severely myopic eyes (-6.0 D or greater) of 10 patients with macular holes without retinal detachment were recruited prospectively. All eyes received ICG assisted ILM removal of 3-4 disc diameters around the macular holes. Cases were matched with a prospective control group of 10 emmetropic macular hole patients who underwent identical ICG assisted ILM peeling surgery in the same period. RESULTS: The mean refractive error in the myopic and control group was -11.8 D and +0.3 D, respectively (two tailed t test, p < 0.001). The mean follow up duration for the myopic and control group was 12.1 and 13.3 months, respectively (two tailed t test, p = 0.63). The primary anatomical closure rate in both groups was 90% (Fisher's exact test, p = 1.0). For both the myopic and control groups, there were significant improvement in the mean log MAR visual acuity after the surgery with improvements from 0.86 to 0.57 for the myopic group (two tailed t test, p = 0.015) and 0.89 to 0.44 for the control group (two tailed t test, p = 0.002). The mean preoperative and postoperative visual acuity, rates of final visual acuity of 20/50 or better, and improvement of two or more lines were not statistically different between the two groups. CONCLUSION: ICG assisted ILM peeling in macular hole surgery for severely myopic eyes without retinal detachment gives promising anatomical and visual outcomes, which are comparable to that of non-severely myopic eyes.     

Anatomical and visual outcomes of idiopathic macular hole surgery with internal limiting membrane removal using low-concentration indocyanine green

PURPOSE: To report the anatomical, visual, and optical coherence tomography (OCT) results of using a brief application of a low concentration of indocyanine green (ICG) to assist the removal of internal limiting membrane (ILM) during idiopathic macular hole repair. METHODS: Retrospective, interventional, noncomparative case series of 59 eyes of 57 patients with stage 2, 3, or 4 idiopathic macular holes who underwent pars plana vitrectomy with removal of ILM assisted by a brief (<30 seconds) intravitreal application of 0.125% (1.25 mg/mL) ICG. RESULTS: The median follow-up period was 13 months (range, 2-40 months). Anatomical closure of the macular hole was achieved in 58 eyes (98%) with a single surgery. Visual acuity improved from a preoperative mean of 20/100 to 20/60 postoperatively (P < 0.0001). Twenty-nine eyes (49%) had postoperative visual acuity of 20/50 or better. Visual acuity improved by > or =2 lines in 43 eyes (73%) and between 0 and 2 lines in 13 eyes (22%) and decreased in 3 eyes (5%). Postoperative OCT showed closure of macular hole with normal foveal depression in 49 (89%) of 55 eyes. CONCLUSION: A brief application of ICG at a low concentration appears to provide a safe and effective way of assisting ILM peeling during idiopathic macular hole surgery.

Abstract：

Objective To investigate the efficiency, security and convenience of applying ICG by hypertonic glucose diluting staining to inner limiting membrane to treat idiopathic macular hole. Methods Choose 16 cases (16 eyes) of complex vitreoretinal surgery as group 1 and 18 cases (18eyes) as group 2. Group 1 underwent a subtotal pars plana vitrectomy and gas-liquid exchange, then removal of inner limiting membrane by applying ICG staining to inner limiting membrane. Group 2 underwent a subtotal pars plana vitrectomy and removal of inner limiting membrane directly applying ICG by hypertonic glucose diluting staining to inner limiting membrane. Follow up for 3-8 months. Results Both two groups had the removal of inner limiting membrane successfully. The rate of macular hole closure obtained 100% in two groups. The visual acuity and best corrected visual acuity in two groups raised significantly. There were no statistically significant differences in the best corrected visual acuity postoperative between the two groups. The times of removal of inner limiting membrane in group 2 was slower than in the group 1 (P ＜0.05). The postoperative peak amplitude of MERG's second-order response of peripheral retina was significantly lower than that of pre-operative in group 1, but there was not significantly different in group 2. Conclusions Applying ICG by hypertonic glucose diluting staining to inner limiting membrane to treat macular hole is efficient, secure and convenient. Offering a new selection for staining to inner limiting membrane, but the long-term effectiveness, safety and the operation technique need further observation and summary.     

Macular hole surgery with or without indocyanine green stained internal limiting membrane peeling

Background: To compare the anatomical and visual outcome in primary idiopathic macular hole surgery with or without indocyanine green (ICG) stained internal limiting membrane (ILM) peeling. Methods: The medical records of the last 40 consecutive eyes receiving primary idiopathic macular hole surgery with gas as internal tamponade performed by a single surgeon were retrospectively reviewed and analysed. All eyes had a follow‐up period of at least 6 months. In the initial 22 consecutive eyes, no ILM peeling was performed (non‐ILM peeling group). The subsequent 18 eyes underwent surgery with ICG‐stained ILM peeling (ILM peeling group). Results: The primary anatomical closure rates were 88.9% and 59.1% in the ILM peeling group and non‐ILM peeling group, respectively. The difference was statistically significant (Fisher's exact test, P = 0.038). Improvement in visual acuity was more marked in the ILM peeling group than in the non‐ILM peeling group, with a mean improvement of 3.6 and 1.3 lines, respectively (two‐tailed t‐test, P = 0.036). There were significantly more cases with improvement of two or more lines of visual acuity after surgery, with 66.7% in the ILM peeling group and 31.8% non‐ILM peeling group (Chi‐square test P = 0.028). However, there was no significant difference in the final postoperative logMAR best‐corrected visual acuity between the two groups (two‐tailed t‐test, P = 0.073). Conclusions: Based on this study, ICG‐stained ILM peeling seems to improve the anatomical and visual outcome in primary idiopathic macular hole surgery. Further studies in this aspect are warranted.
