目的:对特发性黄斑裂孔患者进行玻璃体切割手术(pars plana vitrectomy,PPV)及内界膜(inner limiting membrane,ILM)剥除、气体眼内填充后,应用频域光学相干断层扫描仪(spectral domain optical coherence tomography,SD-OCT)观察黄斑裂孔术后的闭合黄斑孔的黄斑区视网膜厚度(retinal thickness,RT)变化。方法:非随机、回顾性临床病例研究。筛选我院2011-03-01/2013-06-30入院诊断为“特发性黄斑裂孔”的患者17例17眼,均为同一术者行25G-PPV和ILM剥除、短效气体填充、黄斑孔闭合良好、随访观察超过6mo以上者。所有患者术后均使用Topcon公司SD-OCT进行术眼及对侧正常眼的黄斑区线性扫描检测黄斑区视网膜厚度变化。黄斑区视网膜厚度根据ETDRS分成9个区域。术后观察随访时间分别为术后3~5wk(A期)、术后2~3mo(B期)、术后>6mo(C期)。结果:在A期中,OCT检查的黄斑区视网膜厚度:术眼C,IS,II,IN,OS,OI和ON较对侧眼相应区域的厚度增加(P<0.01),而IT和OT(291.58±18.97μm,250.83±21.21μm)较对侧眼(280.33±20.82μm,242.08±24.02μm)的差异无统计学意义(P>0.01)。在B期中,术眼II,IN,OS和ON区域较对侧眼相应区域视网膜厚度增加(P<0.01),而术眼C,IS,IT,OI和OT区域较对侧正常眼相应区域的视网膜厚度值差异无统计学意义(P>0.01)。C期中,除术眼IN区较对侧眼厚度增加外(P<0.01),余C,IS,II,IT,OS,OI,ON和OT较对侧眼相应区域厚度均无明显变化(P>0.01)。另外,C期的术眼ON和IT视网膜厚度较A期有明显下降(P<0.01)。结论:特发性黄斑裂孔术后出现黄斑区视网膜厚度的持续变化,可能与ILM的剥除导致黄斑区显微组织结构的变化有关。SD-OCT为黄斑裂孔术后随访观察提供了客观便捷的观察工具,为进一步研究ILM剥除对黄斑区视网膜的远期结构及对视功能的影响提供了依据。  相似文献

PURPOSE: To prevent triamcinolone acetonide (TA) deposition in the macular hole by use of whole blood during TA-assisted internal limiting membrane (ILM) peeling. METHODS: The prospective, interventional case series study included 18 consecutive idiopathic macular holes (18 patients) that underwent TA-assisted internal limiting membrane (ILM) peeling for macular hole treatment. After core vitrectomy, autologous whole blood was applied to cover the macular hole. Pre-prepared TA solution was gently injected onto the macular area. Residual TA particles were removed after ILM peeling. Closure rate of macular hole, preoperative and postoperative median visual acuity, and retinal changes were evaluated. RESULTS: Autologous whole blood prevented the deposition of TA particles in the macular hole. The ILM could be recognized after TA-assisted visualization for removal. Average follow-up time was 8.6 months. The hole was closed with one surgery in 17 eyes (94%); visual acuity improved in 15 eyes (83%). Preoperative median best-corrected visual acuity was 20/100 (range = 20/400-20/50). Postoperative median best-corrected visual acuity was 20/40 (range = counting fingers-20/20). CONCLUSIONS: Whole blood can prevent TA particle deposition in the macular hole. Potential toxicity of TA on retinal pigment epithelium and retina also may be reduced.  相似文献

PURPOSE: To reduce the retention of indocyanine green (ICG) on the retina by selectively staining the internal limiting membrane (ILM) with whole blood during ICG-assisted ILM peeling. DESIGN: Interventional, non-comparative, prospective case series. METHODS: Autologous whole blood was applied to cover the macular area and selectively removed to expose the area needed to be stained. ICG solution (1 mg/ml) diluted in glucose 5% was used to selectively stain the macular area. The stained ILM was removed completely. RESULTS: We studied 22 patients with macular holes, eight with macular pucker and four with diabetic macular edemas. The ILM was selectively stained successfully by ICG with whole blood. One month after surgery, we found no autofluorescence in the posterior pole by infrared-sensitive camera. CONCLUSIONS: Autologous whole blood can help to achieve the goal of selectively staining ILM, further reducing the retention of ICG. It may further reduce ICG toxic effects.  相似文献

AIMS: To evaluate the effect of pars plana vitrectomy (PPV) with or without internal limiting membrane (ILM) peeling on the closure and configuration of idiopathic macular holes (IMH). METHODS: PPV was performed for IMH on 44 eyes with ILM peeling (ILM peeled group) and on 42 eyes without ILM removal (ILM preserved group). Optical coherence tomography (OCT) was performed on 34 ILM peeled eyes and 14 ILM preserved eyes after successful surgery. The repaired macular holes were classified by the OCT images as being of "good shape" (nearly normal foveal contour) or "poor shape" (abnormal foveal contour with flat fovea and steep edge, or with a thick retina without a foveal pit). RESULTS: The anatomical closure rate was significantly higher in the ILM peeled group (93.2%) than in the ILM preserved group (76.2%) (p = 0.028). In the ILM peeled group, 31 eyes had a fovea of good shape and three eyes had a fovea with a poor shape, while in the ILM preserved group, six eyes had a fovea of good shape and eight eyes had a fovea of poor shape. The percentage of eyes with good macular configuration in the ILM peeled group was significantly higher than in the ILM preserved group (p = 0.0003). No significant difference was found in the postoperative visual acuity and the increase of visual acuity between the ILM peeled group and the ILM preserved group (p = 0.26, and p = 0.91 respectively). There was also no significant difference in the postoperative visual acuity and improvement in visual acuity between eyes with a fovea of good shape and those with fovea of poor shape fovea (p = 0.99 and p = 0.66, respectively). CONCLUSIONS: ILM peeling may provide better anatomical success and recovery of the macular shape, but the postoperative visual acuity and improvement of visual acuity were not related to the morphological results.  相似文献

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.  相似文献

Ultrastructure of internal limiting membrane in myopic foveoschisis   总被引:2,自引:0,他引:2  
PURPOSE: To reveal the pathogenesis of myopic foveoschisis (MF). DESIGN: Clinicopathological report. METHODS: Internal limiting membranes (ILMs) were collected from ten patients with MF and five patients with idiopathic macular hole (IMH) as a control. Samples were subjected to transmission electron microscopic study. Characteristics of the ILM were compared between the two groups. RESULTS: Collagen fiber and cell debris were identified on the inner surface of ILM in seven eyes (70%) with MF, significantly more (P < .05) than found in IMH subjects (0%). More fibrous glial cells were likely to be found on the inner surface of ILM. No significant difference in fibroblast-like cell adhesion was observed. CONCLUSIONS: Collagen fiber and cellular component are suggested to play an important role in developing MF. ILM peeling may be essential for vitrectomy for MF.  相似文献

Background We investigated the feasibility and safety of a 25-gauge, transconjunctival sutureless vitrectomy system for macular hole repair. Methods Eighty-four eyes of 77 consecutive patients with idiopathic macular hole were operated on using a transconjunctival sutureless 25-gauge vitrectomy system. A complete vitrectomy was performed using triamcinolone acetonide to visualize the vitreous gel and to remove the posterior vitreous cortex. The macular hole was covered with autologous whole blood, and the internal limiting membrane (ILM) was stained with indocyanine green. The ILM was peeled and a fluid-air exchange performed. The globe was filled with gas, and the patient was kept in a prone position for 1 week. Surgery-related complications, macular hole closure on optical coherence tomography (OCT) and visual outcome were evaluated. Results No intra- or postoperative complications were recorded. It was noted in particular that sclerotomies did not require sutures. No postoperative hypotony or endophthalmitis was observed. OCT showed macular hole closure in 93% of the cases. The median preoperative best-corrected visual acuity was 20/200 and improved significantly (p<0.05) to a median best-corrected visual acuity of 20/67 (median follow-up 6.5 months). Conclusion A 25-gauge transconjunctival sutureless vitrectomy, visualization of the vitreous with triamcinolone acetonide, protection of the macular hole with autologous whole blood and staining of the ILM using indocyanine green are safe and efficient techniques for macular hole repair.
