不同方法剥除内界膜治疗特发性黄斑裂孔的比较研究

目的比较采用吲哚氰绿(ICG)、苔盼兰(TB)及不染色剥除内界膜治疗特发性黄斑裂孔的疗效。方法前瞻性随机连续病例研究。2001年1月-2005年9月在我院被确诊为IMH并行玻璃体切除联合内界膜剥除的92例92眼被纳入本研究。所有病例按内界膜剥除时采用不同的染色方法随机分为3组:1)A组(34例34眼):不使用染色剂;2)B组(28例28眼);0.5%吲哚氰绿(ICG);3)C组(30例30眼);0.1%苔盼兰(TB)。比较三者间裂孔内界膜剥除的情况、裂孔愈合情况,术后最佳矫正视力以及视力提高情况的差异。统计学方法采用x2检验和单因素方差分析。结果三组间在患者的年龄,性别、患病时间、术前视力、裂孔分期及大小上差异无显著性意义(p>0.05)。ICG和TB均能有效地使内界膜着色。未染色组与TB染色组各有1眼未完全剥除裂孔旁内界膜,其余眼均完全剥除了内界膜。内界膜剥除的所需时间未染色组(6.3±1.2)min,ICG染色组(4.1±0.83)min,TB染色组(4.2±0.6)min,统计学分析表明未梁色组与染色组间差异有显著性意义,但ICG染色组与TB染色组间差异无显著性意义(p>0.05)。三组间在术后裂孔闭合率、最佳矫正视力和视力提高的程度上均无显著性差异(p>0.05)。三组病例均未发生严重并发症。结论内界膜染色可显著提高内界膜的能见度,提高内界膜剥除的效率。尽管与未染色相比,采用内界膜染色的裂孔的闭合率、视功能的恢复情况并无差异,但考虑到染带来的潜在毒副作用,建议尽可能在不染色的条件下剥除内界膜。     

Observation of persistent fundus fluorescence after internal limiting membrane peeling assisted by indocyanine green solution of different concentrations

 Purpose: To investigate how long indocyanine green (ICG) remains in the fundus after vitreoretinal surgery assisted with ICG, and to identify factors that influence the persistence duration. Methods: Fifty five eyes diagnosed as idiopathic macular hole (Stage 2 and 3) were randomly divided into five groups. ICG solution at concentrations of 5, 2.5, 2.5, 1.25, and 0.5 mg/ml, employed in cases of Group I to V respectively, was applied to stain the internal limiting membrane (ILM) during the procedure of internal limiting membrane peeling. A prospective study was carried out after pars plana vitrectomy and ILM peeling were performed on 55 eyes with Stage 2, 3, or 4 idiopathic macular holes. Infrared fundus pictures were obtained in all patients before and after surgery. Results: High levels of fluorescence from residual ICG (ICG hyperfluorescence) were mainly localized at the posterior pole of the fundus after surgery. In Group Ⅰ, Ⅱ, III, IV and V, the duration of persistence of flurorescence from ICG was 8.33±0.87, 3.59±0.94, 3.75±0.79, 2.30±0.48, and 1.29±0.49 months, respectively. Although no significant difference was detected between Group Ⅱ and Group III, the general inter-group difference was significant among the five groups in which different ICG concentration was applied. In Group III, even though 90% of the macular holes acquired anatomical closure, ICG hyperfluorescence was detected in the macular area. Conclusion: ICG remains in the fundus for a period of months. The persistence duration of fluorescence from ICG is positively correlated with the concentration and the staining time of ICG. Hyaluronan is beneficial in reducing the amount of ICG residue in the macular area.     

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.     

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.     

Visual outcomes following ICG assisted ILM peel for Macular Hole

PURPOSE: To evaluate the anatomical and visual outcome of indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling for macular hole surgery. A literature search identified potential factors that may affect the functional success of the procedure. METHODS: Retrospective case note review of 14 consecutive patients undergoing phaco-vitrectomy, gas and ICG-assisted ILM peeling for macular hole from July 2001 to July 2002. A 0.5% ICG solution (osmolarity 270 mOsm) was left in contact with the retina for 1-3 min. The outcome measures were hole closure, change in visual acuity, and macular pigmentary changes. RESULTS: Anatomical hole closure was achieved in 13 of 14 eyes (92.8%). The mean logMAR Snellen acuities were 0.80 (range 0.60-1.30) preoperatively and 0.77 (0.48-1.30) postoperatively. Seven eyes (50%) developed retinal pigmentary changes in the macular area. CONCLUSIONS: ICG-assisted ILM peeling for macular hole surgery achieves high rates of anatomical hole closure, but functional results are less encouraging. Previous studies suggest toxicity of the ICG to the retina, at the level of the RPE or inner retina. The results may be optimized by using a lower concentration, iso-osmolar, viscous solution, and by minimizing contact time of the solution and intensity, and duration of illumination.     

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.     

Visual field defects after macular hole surgery with indocyanine green-assisted internal limiting membrane peeling

PURPOSE: To report visual field defects after macular hole surgery with indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling. DESIGN: Interventional consecutive case series. METHODS: A retrospective review of 140 eyes with macular hole after vitrectomy with ILM peeling. The group with 0.25% of ICG for ILM peeling consisted of 96 eyes. The group without ICG consisted of 44 eyes. RESULTS: Nasal visual field defects occurred in 11 eyes, temporal visual field defects in seven eyes, and concentric visual field defects in one eye. In the group with ICG, nasal visual field defects were far higher in the left eye than in the right eye. CONCLUSIONS: We speculate that the postoperative nasal visual field defects were caused by the enhanced toxicity of ICG resulting from the exposure to illumination.     

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 6mo, 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 hole closure rate, and best corrected visual acuity (BCVA) were compared between the two groups after surgery. RESULTS: At postoperative 1, 3, and 6mo, 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.
