Abstract Background To compare the functional and anatomic outcomes at 24 months of eyes with a primary macular hole that failed to close after a prior surgery and were treated with either an autologous transplantation of internal limiting membrane (AT-ILM) or the retina expansion (RE) technique. Methods Retrospective, single center, comparative study of 28 eyes with a macular hole that failed to close after a prior vitrectomy. All eyes had a size of ≥ 500 μm. Participants were divided into two groups according to the type of intervention performed: AT-ILM group (n = 14) and RE group (n = 14). Main outcomes measured were the MH closure rate assessed by spectral-domain optical coherence tomography (SD-OCT) and the best-corrected visual acuity (BCVA) at 24 months after surgery. Results Patients in the AT-ILM group experienced a statistically significantly improved post-operative BCVA (median 49.50 letters, range 20–66 letters) over the pre-operative BCVA (median 39 letters, range 18–52 letters) (p-value = 0.006 Wilcoxon paired sample test). In contrast, patients in the RE group did not achieve a statistically significant improvement (p-value = 0.328, Wilcoxon paired sample test). The median pre-operative BCVA was 35 letters (range 18–52 letters), whereas the median post-operative BCVA was 39 letters (range 16–66 letters). At 24 months of follow-up, 85.7% of patients in the AT-ILM group achieved closure compared to 57.1% in the RE group (p-value = 0.209, Fisher’s exact test). Multivariate analysis showed that MH size and baseline BCVA were important determinants of post-operative BCVA. The baseline MH size was the only significant pre-operative factor that influenced MH closure. Conclusions This study demonstrates similar closure rates for both groups however better visual outcomes were obtained with the AT-ILM.

Abstract Background Inverted Internal Limiting Membrane (ILM)-flap technique would seem to lead to higher closure rate and better visual acuity than traditional procedure with ILM peeling for the treatment of large macular hole (LMH). Visual acuity recovery does not reveal many other functional changes related to surgical approach. Our purpose was to evaluate macular function and morphology over a 1-year follow-up after inverted ILM-flap technique for LMH by using microperimetry in order to predict visual prognosis. Methods This study was a prospective unrandomized single-center study. 23 eyes of 22 patients with idiopathic LMH, with a minimum diameter ranging from 400 to 1000 μm, were included. All patients underwent vitrectomy with inverted ILM-flap technique and gas tamponade. We analyzed macular hole closure rate and functional outcomes including best-corrected visual acuity (BCVA), macular sensitivity (MS) at central 12° and central macular sensitivity (CMS) at central 4°, and fixation behavior as bivariate contour ellipse area (BCEA, degrees2) at 68%, 95%, and 99% of fixation points measured by microperimeter, over a follow-up of 12 months. Results The macular hole closure rate was 98%. The BCVA improved from 20/230 (Logmar, 1.06 ± 0.34) to 20/59 (logMar, 0.47 ± 0.45) at last follow-up (p < 0.001). Retinal sensitivity and BCEA significantly improved (MS, p = 0.001; CMS, p < 0.0001; BCEA: 68%, p < 0.01; 95%, p < 0.01; 99%, p = 0.001). Multiple stepwise regression analysis showed the final BCVA was significantly associated with macular hole size (β = 0.002, p = 0.03), preoperative MS (β = − 0.06, p = 0.001) and BCEA at 95% and 99% of fixation points (β = − 0.12, p = 0.01; β = 0.06, p = 0.01). Conclusions Inverted ILM-flap technique for LMH results in good morphologic and functional outcomes. Macular hole size and microperimetric parameters as preoperative MS and BCEA have a predictive role on post-surgical visual acuity.

Abstract Purpose To investigate morphological and functional outcomes of the inverted internal limiting membrane (I-ILM) flap technique in large (≥ 400 μm) idiopathic full-thickness macular holes (FTMH) over a follow-up period of 12 months. Methods In this retrospective study, 55 eyes of 54 consecutive patients were enrolled. Best-corrected visual acuity (BCVA) and spectral-domain optical coherence tomography (SD-OCT, Heidelberg, Spectralis) were performed preoperatively as well as 1, 3, 6, 9, and 12 months postoperatively. Special focus was put on the reintegration of outer retinal layers and the different ILM flap appearances. Results FTMH closure rate was 100% (55/55). BCVA significantly improved over the follow-up period of 12 months from 0.98 ± 0.38 LogMAR preoperatively to 0.42 ± 0.33 LogMAR at 12 months postoperatively (p < 0.001). There was no significant correlation between the three different ILM flap appearances and BCVA. Better preoperative BCVA, complete restoration of the external limiting membrane (ELM), higher macular hole index (MHI), and smaller MH base diameter were associated with higher improvement of BCVA. Conclusion Our study highlights the favorable morphological and functional outcomes of the I-ILM flap technique in the short as well as in the long term. While complete ELM restoration revealed to be an important factor for improvement in BCVA, the different postoperative ILM flap appearances seem not to be related to BCVA.

Background: Vitrectomy with internal limiting membrane (ILM) peeling is an effective surgical procedure for the treatment of macular holes (MHs). However, there is a possibility of poor postoperative anatomical closure with conventional ILM peeling for MHs larger than 400 μm. Therefore, a novel inverted ILM flap technique was developed for such cases. Objectives: This meta-analysis study was performed to evaluate and compare the anatomical and visual outcomes of the inverted ILM flap technique and ILM peeling in large MHs. Methods: The Cochrane Library, PubMed, and Embase databases were searched to identify randomized controlled trials (RCTs). The trial eligibility and risk of bias were assessed according to Cochrane review methods. The primary outcome measures included MH closure rate and postoperative visual acuity (VA). Subgroup analysis of postoperative VA based on follow-up time was also conducted. Pooled odds ratios (ORs), weighted mean difference (WMD), and 95% confidence intervals (CIs) were calculated. Statistical analysis was performed using RevMan 5.3 software. Results: Five RCTs with a total of 155 eyes in the inverted ILM flap group and 161 eyes in the ILM peeling group were included in this meta-analysis. Statistical meta-analysis revealed that the overall MH closure rate in the inverted ILM flap group was significantly higher than that in the ILM peeling group (OR, 3.10; 95% CI, 1.25 to 7.66; P = 0.01). The postoperative VA was significantly better in the inverted ILM flap group than ILM peeling group (WMD, -0.14; 95% CI, -0.21 to -0.07; P = 0.0002). The subgroup meta-analysis indicated that the postoperative VA was significantly better in the inverted ILM flap group than ILM peeling group (WMD, -0.17; 95% CI, -0.26 to -0.08; P = 0.0004) at the 3-month follow-up. However, no significant difference was observed between the two groups at the 6-month follow-up (WMD, -0.09; 95% CI, -0.20 to 0.02; P = 0.10). Conclusions: Vitrectomy with inverted ILM flap technique showed a higher anatomical closure rate as well as visual gain—although only in the short-term as no difference in visual recovery was found at the 6-month follow-up—than did ILM peeling in large MHs. The inverted ILM flap technique should be considered as a preferred and routine procedure for the treatment of patients with MHs larger than 400 µm.

PurposeThe aim of this study was to determine the effect of the inverted internal limiting membrane (ILM) flap technique on the macular hole (MH) closure and foveal microstructure recovery of patients with highly myopic MH.MethodsPars plana vitrectomy and gas tamponade with the inverted ILM flap technique (19 eyes) or with the ILM peeling technique (21 eyes) were performed in patients with highly myopic MH with or without retinal detachment. The rate of MH closure and retinal reattachment, the reconstructive anatomical change of the foveal microstructure and the best-corrected visual acuities (BCVA) of the two groups were compared.ResultsThe anatomic closure rate was statistically significantly higher in the inverted group (100%) than in the peeling group (66.7%; p=0.009). All eyes with MH retinal detachment had successful retinal reattachment in these two groups. However, the rate of the external limiting membrane (ELM) and ellipsoid zone (EZ) (p=0.020), as well as gliosis (p=0.049) in macular area, detected by OCT, was significantly greater in the inverted group than in the peeling group. The postoperative BCVA was significantly better in the eyes with ELM, EZ (p=0.031) and gliosis (p=0.008), but without hyperreflective foci (p=0.001).ConclusionsThese findings demonstrate that the inverted ILM flap technique has better efficacy than the ILM peeling technique for patients with myopic MH in closure rate, foveal microstructure and postoperative BCVA.

Purpose. To investigate the outcome of pars plana vitrectomy (PPV) with suitable internal limiting membrane peeling (ILM) and air tamponade for patients with highly myopic foveoschisis-associated lamellar macular hole (MH). Methods. This retrospective interventional case series included 11 patients with highly myopic foveoschisis-associated lamellar MH who underwent PPV and indocyanine green-aided ILM peeling up to the temporal vascular arcades. Following air tamponade after surgery, all patients were instructed to maintain a face-down position. The patients were followed up for over 1 year and evaluated for MH closure and the best-corrected visual acuity before and after surgery. Results. The mean ± standard deviation values of patient age, axial length, and follow-up duration were 67.82 ± 6.54 years, 29.21 ± 1.95 mm, and 24.27 ± 8.11 months, respectively. After surgery, the lamellar MH closed in all eyes, and 10 eyes showed vision improvement at the 1-month, 3-month, and final follow-up evaluations. One patient showed decreased vision at 2 years after surgery, with patchy chorioretinal atrophy in the macular region. Myopic foveoschisis showed resolution in three eyes and alleviation in eight. Ten patients underwent cataract surgery during PPV. Conclusion. Extension of ILM peeling up to the temporal vascular arcades and air tamponade after PPV may improve the visual function and rate of MH closure for patients with highly myopic foveoschisis-associated lamellar MH.

518 Background: Our goal was to describe the change of treatment paradigms for metastatic renal cell carcinoma (mRCC) since targeted therapy became available in 2006. Methods: In this cohort population study we retrospectively investigated all mRCC patients who were treated with targeted therapy between 06/2006 and 06/2012 in the Department of Urology of the University of Münster. To distinguish nominal variables Fisher's exact test was used, in other respects Pearson's χ² test. For metrical variables the Mann-Whitney-U-Test was used. The log-rank test was chosen to derive differences between two or more groups with regard to survival. A p value <0,05 was considered statistically significant. Results: 50/158 (31.6%) patients with a median follow-up of 362 days were initially treated with immunotherapy. The most often used second line treatment after immunotherapy was sorafenib (29 patients, 58.0%). As first line treatment sunitinib was chosen most frequently (68 patients, 63.0%). There was no statistically significant difference in survival between the patients who were treated with immunotherapy and those who were not (572 vs. 554 days, p=0,745). 134 (84.4%) patients received cytoreductive nephrectomy before systemic treatment start. Comparing the survival curves there was a significant survival benefit in favor of nephrectomized patients (632 vs. 169 days, p<0,0001). Conclusions: After introduction of the new agents treatment paradigms have changed substantially. Immunotherapy is used only rarely. Cytoreductve nephrectomy should continue to be regarded as standard treatment.

Background:  A macular hole is a full-thickness defect of retinal tissue involving the anatomic fovea, thereby affecting central visual acuity. Pars plana vitrectomy and gas tamponade is a recognised modality of treatment for macular hole.Larger holes are more likely to remain open after repair and late reopening after an initially closed macular hole is seen in macular holes larger than 400 μm.Aims and Objective: To evaluate the anatomical and functional outcome of pars plana vitrectomy with internal limiting membrane peeling for chronic stage 3 macular hole.Materials and Methods: Records of 15 patients with stage 3 chronic macular holes operated from 1st January 2013 to 30th June 2013 and completed 1 year of follow up were retrospectively evaluated and included in the study. Preoperative best distance corrected visual acuity (BCVA), preoperative macular hole size, final BCVA and macular hole status at 1 year follow up were recorded. Macular hole closure and visual improvement was calculated. Correlation of macular hole closure and visual improvement with various macular hole parameter was estimated.Results: Eleven (73.3%) macular holes closed at 1 year follow-up. Mean BCVA improved from 1.2 ± 0.27 to 0.89 ± 0.36 logarithm of minimum angle of resolution at 1 year (p<0.001). Visual improvement was seen in only eight (53.3%) eyes. Both macular hole closure and visual improvement showed no correlation with minimum linear diameter, base diameter and hole height.Conclusion: Chronic stage 3 macular hole can be closed successfully in majority of patients with fairly good visual improvement. Macular hole parameters of stage 3 holes may not have any correlation with the anatomical and visual outcome.Asian Journal of Medical Sciences Vol.7(6) 2016 43-46
