Abstract
PURPOSE To report the efficacy of Descemet's Membrane (DM) transplantation over the macular hole in patients with recurrent high myopic macular hole (HMMH) associated with retinal detachment (RD). METHODS Six eyes of six patients with wide posterior staphyloma including MH and recurrent HMMH associated with RD were included to this retrospective study. All patients underwent pars plana vitrectomy and DM obtained from eye bank was placed over the macular hole during the surgery. Silicone oil endotamponade was used as endotamponade and removed within 6 months following surgery. Pre-operative and post-operative ophthalmologic examination and optical coherence tomography findings were recorded. RESULTS The mean follow-up time was 18.53 ± 7.36 months. Macular hole closure was achieved in all patients (100%). Best-corrected visual acuity was improved from 1.51 ± 0.55 logMAR to 1.08 ± 0.50 logMAR (p = 0.043). No complications due to surgery or DM during follow-up. No DM dislocation or hole re-opening occurred after surgery. CONCLUSION DM transplantation during vitrectomy may be an effective treatment for the recurrent HMMH associated with RD. KEY MESSAGES What is known Various surgical techniques have been tried for recurrent high myopic macular hole associated with retinal detachment, but satisfactory anatomical and functional success rates have still not been achieved. WHAT IS NEW The study demonstrates that Descemet's membrane transplantation is a safe and effective option for treating recurrent high myopic macular hole associated with retinal detachment. This is a novel technique that may overcome the limitations of existing approaches. The findings suggest that Descemet's membrane transplantation could become a promising addition to the surgical options for recurrent high myopic macular hole associated with retinal detachment.

Abstract
INTRODUCTION Highly myopic macular hole retinal detachment (MHRD) is often associated with a poor prognosis, and there is currently no optimal treatment. Platelet-rich fibrin (PRF), an autologous blood product, has been shown to promote tissue regeneration. This prospective, randomized, controlled study investigated the efficacy of conventional internal limiting membrane (ILM) peeling versus PRF membrane transplantation in highly myopic MHRD. METHODS Eyes with highly myopic MHRD were randomly assigned to either a conventional ILM peeling group (IP group, n = 19) or a PRF membrane transplantation group (PMT group, n = 21). The study followed participants for a period of 6 months. The primary outcome measure was macular hole (MH) closure assessed using optical coherence tomography. Secondary outcomes included best-corrected visual acuity (BCVA), central retinal thickness (CRT), superficial vascular density (SVD), deep vascular density (DVD), rate of retinal reattachment, and any complications encountered. RESULTS MH closure was achieved in a significantly greater proportion of eyes in the PMT group (21/21, 100.00%) compared to the IP group (15/19, 78.95%) (P = 0.042). Retinal reattachment was accomplished in all patients (100.00%) within both groups. Except for an insignificant difference in BCVA observed at 1 week post-surgery in the IP group, significant improvements in BCVA and CRT were documented in both groups across all other post-operative time points. Final BCVA (P = 0.040), CRT (P = 0.002), SVD (P = 0.002), and DVD (P = 0.013) were all significantly higher in the PMT group compared to the IP group. No serious complications were identified in either group. CONCLUSIONS This study demonstrated the superiority of PRF membrane transplantation compared to conventional ILM peeling in promoting MH closure and enhancing retinal vascular density in patients with highly myopic MHRD. Additionally, PRF membrane transplantation effectively restores retinal reattachment, improves visual function, and increases retinal thickness without introducing additional complications.

Abstract
A 64-year-old highly myopic woman with macular hole retinal detachment (MHRD) in her left eye underwent vitrectomy, internal limiting membrane (ILM) peeling, and epiretinal implantation of a 4-mm diameter human amniotic membrane (hAM) patch. One month later, she developed a bullous superior RD in her right eye, associated with a huge MH and multiple posterior breaks. Vitrectomy and ILM peeling were combined with a 15-mm epiretinal hAM patch implantation. One year later, both eyes showed successful MH closure, but the right eye developed an eccentric hAM patch contraction starting 6 months postoperatively, causing a localized stable superonasal RD.

Abstract
PURPOSE To compare the surgical results of vitrectomy with untreated or pretreated lyophilized human amniotic membrane grafts covering in treating retinal detachment related to posterior retinal breaks above chorioretinal atrophy in pathologic myopia. METHODS Nineteen patients with retinal detachment related to macular hole (MH) located above macular atrophy and/or posterior paravascular retinal breaks (PRBs) located above patchy chorioretinal atrophy in pathologic myopia were included. The eyes of these patients underwent vitrectomy with untreated lyophilized human amniotic membrane covering (n = 10) or perfluorocarbon liquid (PFCL)-assisted pretreated lyophilized human amniotic membrane covering (n = 9; grafts were pretreated in 0.125% indocyanine green and 50% hypertonic glucose solution for 15-20 minutes). The closure of the MH or PRBs, reattachment of the retina, and best-corrected visual acuity were measured postoperatively. RESULTS Postoperatively, graft dislocation or shift was only found in two eyes (20%) in the untreated group. The closure rate of the MH or PRBs was 80% (8/10) and 100% (9/9) in the untreated group and the pretreated group, respectively. The occurrence rate of excessive gliosis was 40% and 11% in the untreated group and the pretreated group, respectively. In both groups, best-corrected visual acuity was improved and the retinal reattachment rate was 100% at the final visit. CONCLUSION Perfluorocarbon liquid-assisted pretreated lyophilized human amniotic membrane graft covering was effective in treating retinal detachment related to MH and/or PRBs situated above macular atrophy or patchy chorioretinal atrophy in pathologic myopia. This technique appeared to reduce graft dislocation or shift, promote the closures of MHs/PRBs, and reduce the occurrence of gliosis.

Abstract
PURPOSE To propose an ultrathin biological amniotic membrane (btAM) thinner than 10 μm as the graft to treat highly myopic macular holes (MH). METHODS This pilot study included 14 patients affected by refractory macular holes associated with high myopia. btAM was used as a bandage covering the holes. The best-corrected visual acuity (BCVA), fundus photography, and optical coherence tomography (OCT) before and after surgery were compared. RESULTS The mean MH size was 865.93 ± 371.72 μm and all the MHs achieved anatomical closure. The btAM located centrally and fully on MHs from fundus photography yet no obvious visual masking was complained. The average BCVA 1 month, 3, and 6 months after surgery were 0.95 ± 0.24, 0.92 ± 0.23, 0.92 ± 0.23 logMAR, respectively, improved significantly compared to pre-operative BCVA (1.24 ± 0.42 logMAR, all P < 0.05). Ten out of 14 (71.4%) exhibited 2C closure patterns (formally closed and no bare RPE) on OCT. CONCLUSION The btAM thinner showed a favorable anatomical success with less risk of parafoveal atrophy or iatrogenic injuries and shortened the dissolving time.

Abstract
PURPOSE To describe a new surgical technique involving the use of a human amniotic membrane (hAM) epiretinal patch to treat a primary macular hole retinal detachment (MHRD) in a highly myopic patient. METHODS A 60 years old highly myopic man was referred to our clinic with a diagnosis of MHRD in his right eye. The patient was pseudophakic, with a visual acuity of counting fingers at the baseline evaluation. Pars plana vitrectomy was performed, a small retinotomy was created at the inner margin of the staphyloma, and membrane blue dual was used to obtain an adequate peeling of the inner limiting membrane. Then, a 1.5 mm diameter circular hAM patch was obtained and positioned over the macular hole with the chorion layer settled over the retina. After a complete fluid-air exchange, 20% sulfur hexafluoride gas was used as endotamponade, and the patient was asked to remain face down for three days. RESULTS Four weeks after surgery, optical coherence tomography (OCT) scan showed the hAM patch, visualized as a distinct hyperreflective layer well integrated with the retina. Nine months after surgery, the macular hole was closed, the retina reattached, the hAM patch was adherent to the retina, and the patient presented a best-corrected visual acuity improved to 0.7 logMar. No postoperative adverse events were registered during the follow-up. CONCLUSIONS Epiretinal hAM implant could represent a novel surgical technique, feasible and easier compared to other current techniques used to treat MHRD in highly myopic patients.

Abstract
PURPOSE The objectives were to assess the long-term morphologic and functional outcome of eyes with unclosed macular hole (MH) in which the internal limiting membrane has been peeled in previous vitrectomy with autologous blood clot-assisted lyophilized human amniotic membrane (LhAM) graft covering. METHODS Twelve eyes with MH unclosed in previous surgery were selected and studied. Autologous blood clot-assisted LhAM graft was used to cover the MH in vitrectomy. The main clinical outcomes including best-corrected visual acuity, closure of MH, and the outcome of LhAM graft were recorded. RESULTS The mean minimum diameter of the MH was 641.7 ± 245.9 µ m and the mean axial length was 27.3 ± 3.50 mm. The LhAM graft was maintained in the former position and all the MH closed in 10 eyes, whereas the graft slipped and the MH unclosed in two eyes. The MH closure rate was 83.3% and the mean best-corrected visual acuity improved significantly from 1.47 ± 0.58 logMAR (Snellen 20/590) preoperatively to 1.17 ± 0.60 logMAR (Snellen 20/296) postoperatively. During 18 to 36 months follow-up, LhAM grafts were attached to the retinal surface in nine eyes, detached from the retinal surface in one eye, dislocated from the fovea in one eye, and inserted into the retina in one eye; and macular atrophy occurred in one eye. CONCLUSION Autologous blood clot-assisted LhAM graft covering provided a simple and effective treatment option for unclosed MH and reduce surgical trauma. Although the graft remained on the macular surface for a long time, it did not affect the recovery of MH and postoperative vision.

Abstract
INTRODUCTION Amniotic membrane (AM) is a popular treatment for external ocular diseases. First intraocular implantations in other diseases reported promising results. Here, we review three cases of intravitreal epiretinal human AM (iehAM) transplantation as an adjunct treatment for complicated retinal detachment and analyze clinical safety. Possible cellular rejection reactions against the explanted iehAM were evaluated and its influence was assessed on three retinal cell lines in vitro. METHODS Three patients with complicated retinal detachment and implanted iehAM during pars plana vitrectomy are retrospectively presented. After removal of the iehAM at subsequent surgery, tissue-specific cellular responses were studied by light microscopy and immunohistochemical staining. We investigated the influence of AM in vitro on retinal pigment epithelial cells (ARPE-19), Müller cells (Mio-M1), and differentiated retinal neuroblasts (661W) . An anti-histone DNA ELISA for cell apoptosis, a BrdU ELISA for cell proliferation, a WST-1 assay for cell viability, and a live/dead assay for cell death were performed. RESULTS Despite the severity of the retinal detachment, stable clinical outcomes were obtained in all three cases. Immunostaining of the explanted iehAM showed no evidence of cellular immunological rejection. In vitro, there was no statistical significant change in cell death or cell viability nor were proliferative effects detected on ARPE-19, Müller cells, and retinal neuroblasts exposed to AM. CONCLUSION iehAM was a viable adjuvant with many potential benefits for treatment of complicated retinal detachment. Our investigations could not detect any signs of rejection reactions or toxicity. Further studies are needed to evaluate this potential in more detail.

Abstract
PURPOSE The treatment of refractory macular holes is controversial, with human amniotic membrane grafts emerging recently as an attractive option. We performed a meta-analysis and systematic review in this paper to assess the results of human amniotic membrane (hAM) in the treatment of refractory macular hole (MH). METHODS We searched the Cochrane Database of Systematic Reviews, Web of Science, PubMed, Embase, China National Knowledge Infrastructure databases, VIP database, Wanfang Data Knowledge Service Platform, Sinomed, Chinese Clinical Trial Registry, and Clinical Trials.gov. Studies reporting hAM for the treatment of refractory MH were included. The outcomes are MH closure rate, visual acuity (VA) improvement rate, and graft dislocation/contracture rate. RESULTS A total of 8 studies on 103 eyes were included, all of which had undergone failed vitrectomy and internal limiting membrane (ILM) peeling. In all studies, the VA improvement rate was 66% (95%CI: 45 to 84%), the MH closure rate was 94% (95%CI: 84 to 100%) and the hAM graft dislocation/contracture rate was 6% (95%CI: 0 to 15%). In the studies using cryopreserved hAM grafts, the MH closure rate was 99% (95%CI: 94 to 100%) and the hAM graft dislocation/contracture rate was 3% (0%, 10%). The VA improvement rates were 94% (95%CI: 79 to 100%) in the retinal detachment subgroup, 37% (95%CI: 20 to 56%) in the pathologic myopia subgroup, and 62% (95%CI: 14 to 100%) in the idiopathic MH subgroup. CONCLUSION Human amniotic membrane in the treatment of refractory MH results in visual improvement. It has a high macular hole closure rate and low dislocation/contracture rate. Cryopreserved hAM grafts might have better outcomes than dehydrated grafts.

Applications of Human Amniotic Membrane Patching Assisted Vitrectomy in the Management of Postoperative PVR in Complex Retinal Detachments. J Clin Med 2023; 12:jcm12031137. [PMID: 36769785 PMCID: PMC9918292 DOI: 10.3390/jcm12031137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 01/18/2023] [Accepted: 01/28/2023] [Indexed: 02/04/2023] Open
Abstract
Human amniotic membranes (hAMs) are extraembryonic tissues currently employed in the treatment of many ocular and systemic diseases. Several reports indicate that hAMs can suppress the signaling pathway of tissue growth factor beta (TGF-β), a cytokine that plays a major role in the pathogenesis of proliferative vitreoretinopathy (PVR) through the induction of epithelial-mesenchymal transition (EMT) in exposed retinal pigmented epithelium (RPE) cells. The present study was conducted to evaluate the efficacy of a modified vitrectomy procedure (hAMP-V) involving the extensive coverage of exposed RPE with hAM patches to prevent postoperative PVR in a series of 15 cases of retinal detachment complicated by severe preoperatory PVR. The primary outcome was to assess the rate of successful retinal reattachment of a single hAMP-V procedure at 6 months from silicone oil removal. Secondary outcomes included the collection of intraoperative data concerning the quantity, size, and scope of hAM patches, and the assessment of postoperative improvements in mean LogMar BCVA at 3 and 6 months. Successful retinal reattachment was obtained in 14 out of 15 eyes (93.3%). Surgical failure due to major recurrence of PVR occurred in 1 out of 15 eyes (6.7%). Postoperative improvements in mean LogMar BCVA were statistically significant (p < 0.05, paired t-test). No intraoperative and postoperative adverse effects were reported. The study helped to refine the surgical technique while also offering cues for future improvements.

Abstract
PURPOSE To determine the efficacy of using a human amniotic membrane to close macular hole retinal detachment in highly myopic eyes. STUDY DESIGN Prospective, consecutive, nonrandomized interventional study. METHODS We included 19 high myopic eyes from 19 patients affected by macular hole retinal detachment who had already undergone vitrectomy with internal limiting membrane peeling. The patients underwent vitrectomy with amniotic membrane transplant. RESULTS Primary success was achieved after 3 months in 89.5% (17 of 19 eyes) and final macular hole closure was obtained in 94.7% (18 of 19 eyes) of the patients. The final retinal reattachment rate was 100%. The final 12-month mean BCVA improved from 20/2000 (2 logMAR) to 20/250 (1.1 logMAR). OCT-angiography revealed a high correlation between the superficial and deep capillary plexus and the final BCVA. CONCLUSION Human amniotic membrane patches can effectively repair macular hole retinal detachment in high myopic eyes in terms of anatomic results and BCVA recovery.

Abstract
Pars plana vitrectomy has become the standard procedure for primary macular holes (MHs) repair, including the removal of the posterior cortical vitreous, the stripping of eventual epiretinal membranes, and finally an intraocular gas tamponade. During this procedure, peeling the internal limiting membrane (ILM) has been proven to increase closure rates and avoid postoperative reopening in several researches. In fact, even in large MHs more than 400 µm, the advantage of peeling off the ILM was highlighted by better anatomical closure rates. Nevertheless, some authors suggested that ILM peeling is not always essential, because it generates various side effects in retinal structure and function. Furthermore, the ideal amount of ILM peeling and the most effective strategies for removing the ILM are still subject of research. Different surgical modifications have been reported as alternatives to traditional peeling in certain clinical settings, including ILM flaps, ILM scraping, and foveal sparing ILM peeling. As regards large MHs, the introduction of ILM inverted flap appeared as a game changer, offering a significantly higher >90% closure rate when compared to traditional ILM peeling. Modifications to inverted ILM flap procedures have been claimed in recent years, in order to define the best area and direction of ILM peeling and its correlation with functional outcomes. Moreover, several innovations saw the light in the setting of recurrent MHs, such as ILM free flap transposition, inverted ILM flap combined autologous blood clot technique, neurosensory retinal flap, and human amniotic membrane (HAM) plug, claiming higher anatomical success rate also in those complex settings. In conclusion, the aim of this review is to report how the success rate of contemporary macular surgery has grown since the turn of the century, especially for big and chronic MHs, analyzing in which way ILM management became a crucial point of this kind of surgery.

Inverted internal limiting membrane flap technique for retinal detachment due to macular holes in high myopia with axial length ≥ 30 mm. Sci Rep 2022; 12:4258. [PMID: 35277581 PMCID: PMC8917174 DOI: 10.1038/s41598-022-08277-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 03/03/2022] [Indexed: 11/25/2022] Open
Abstract
To compare the efficacy of internal limiting membrane (ILM) flap covering to that of ILM flap insertion for the treatment of macular hole retinal detachment (MHRD) in highly myopic eyes with axial length (AL) ≥ 30 mm. We retrospectively analysed the medical records of 48 MHRD patients with high myopia (AL ≥ 30 mm). According to different surgical methods, the patients were divided into a covering group (23 eyes) and an insertion group (25 eyes). The rate of retinal reattachment and MH closure were compared between the two groups, and the related factors affecting the initial anatomical results were analysed. After primary vitrectomy and single silicone oil removal, there were 18 eyes (78.3%) in the covering group, and 20 eyes (80.0%) in the insertion group had retinal reattachment (P = 1.000). Moreover, 16 eyes (69.6%) in the covering group and 17 eyes (68.0%) in the insertion group had their MHs sealed (P = 0.907). The best-corrected visual acuity (BCVA) at 12 months and the improvement in BCVA postoperatively in the two groups were not statistically significant (P = 0.543, 0.955). Logistic regression analysis showed that elongated AL (OR = 1.844, 95% CI 1.037–3.280, P = 0.037) and higher choroidal atrophy (OR = 2.986, 95% CI 1.011–8.821, P = 0.048) were risk factors affecting initial anatomical success. For extremely high-myopia MHRD with AL ≥ 30 mm, ILM flap covering and insertion can both effectively seal the MH and promote retinal reattachment, but the visual function improvement may still be limited. The longer the AL and the higher the choroidal atrophy, the greater is the risk of initial anatomical failure.

Abstract
PURPOSE To report the long-term outcomes of large diameter epiretinal lyophilized amniotic membranes (lAMs) in recurrent or persistent macular holes (MHs) with or without rhegmatogenous retinal detachment (RRD), in a prospective interventional case series. METHODS Ten eyes of 10 patients underwent pars plana vitrectomy for MH-associated RRD (n = 5) or persistent MH without RRD (n = 5), in a university Hospital. A 3 or 4 mm diameter disc of lAM, stained with 0.06% trypan blue, was inserted with a catheter through a sclerotomy and positioned over the MH. Gas or silicone-oil tamponade was used. At 1 year, the main outcome was anatomic success defined as complete MH closure. Secondary outcomes were best corrected visual acuity (BCVA) recovery, changes in ellipsoid zone (EZ) and external limiting membrane (ELM) defects, complications. Mean follow-up was 13.8 ± 2.9 months (range, 12-18). RESULTS Mean baseline data were minimum and maximum diameters, respectively, 945 ± 330 and 1507 ± 717 μm; axial length 26.58 ± 3.38 mm; and number of prior surgeries 1.4 ± 0.96. At 1 year, anatomic success was achieved in eight eyes (80%), and two had reduced diameter of MH. All RRDs were reattached without recurrence. Mean logMAR BCVA improved from 1.92 ± 0.58 to 1.17 ± 0.57 (p < 0.001), with nine eyes (90%) achieving ≥0.3 logMAR improvement. Mean EZ and ELM defects decreased (p = 0.004, p = 0.003, respectively). Postoperative complications were RRD (n = 1) reattached by subsequent surgery, lAM slightly retracted under silicone (n = 1), foveal atrophy after early lAM displacement (n = 1). CONCLUSION A 1-year follow-up highlighted that epiretinal large discs of blue-stained lAM can help safely close refractory MHs, and provide satisfactory visual recovery.

Abstract
This review evaluates the current surgical management options for refractory and atypical macular holes (MH) and proposes a treatment paradigm for approaching complex cases. A review of literature was performed to deliver a thorough discussion of the epidemiology and pathophysiology of MH as well as the historic evolution of surgical management strategies. With this context established, an update on recent surgical advances for management of large, chronic, and highly myopic MH is provided. New small MH may be adequately treated with pars plana vitrectomy, while those ≥300 μm should undergo internal limiting membrane (ILM) peel. For MH ≥400 μm with risk factors for failure, primary intervention should involve creation of an ILM flap and various methods of flap creation are discussed. For very large MH ≥700 μm or in refractory cases, autologous retinal transplants and other recently proposed procedures should be considered. While typical MHs enjoy high initial surgical success rates, atypical and refractory MH require additional intraoperative and postoperative considerations to maximize surgical success and optimize vision. With many techniques at the surgeon's disposal, patient selection becomes critical to improving outcomes.

Abstract
To describe the surgical outcomes of using human amniotic membrane (hAM) grafts in the management of retinal breaks in diabetic tractional detachment (TRD) and combined tractional and rhegmatogenous retinal detachment (CTRRD). A retrospective case series of 10 eyes with TRD or CTRRD receiving pars plana vitrectomy with hAM grafts implantation, compared with 13 controls receiving the same surgery without hAM grafts. Best-corrected visual acuity (BCVA) and re-detachment rate were compared between two groups. Postoperatively, all eyes in the hAM group had retina attachment without recurrence, while 9 eyes in the control group had retina re-detachment and required additional surgery (0% vs 69.2%, p = 0.003). The BCVA significantly improved in the hAM group (from 1.96 ± 0.95 to 1.44 ± 0.77 in log MAR, p = 0.03), but not improved in control group (p = 0.20). Postoperative optical coherence tomography of the eyes receiving hAM grafts demonstrated glial tissue regeneration and restoration of ellipsoid zone. In diabetic TRD or CTRRD, hAM grafts could be an effective method, with promising outcome. Compared to standard surgery, it could result in higher retina reattachment rate and significant visual improvement. Moreover, it may offer the adjunctive benefit in tissue regeneration and fasten ellipsoid zone restoration.

Abstract
PURPOSE To investigate the surgical outcomes of vitrectomy for macular hole-induced retinal detachment(MHRD), with respect to the surgical adjunctive method used. METHOD We performed retrospective multicenter study of patients who underwent vitrectomy for MHRD. The visual/anatomical outcomes after vitrectomy were analyzed. We also analyzed these outcomes according to surgical method and the presence of persistent macular hole after the vitrectomy. RESULT Thirty-four patients (34 eyes) from 6 hospitals were included in this study. The mean age of the patients was 64.56 ± 12.23 years; 31 patients (91.2%) were female. The mean LogMAR best-corrected visual acuity (BCVA) significantly improved 6 months after vitrectomy (p < .001). Retinal detachment completely improved in 32 eyes (94.1%). The visual prognoses and macular hole closure rates were not different depending on subretinal fluid drainage site. The presence or absence of a persistent macular hole after vitrectomy did not affect the visual outcomes. However, the recurrence of MHRD was significantly higher in eyes with persistent macular holes(p = .015). CONCLUSION The surgeries to treat MHRD differed in terms of the procedure depending on the surgeons, but the visual outcomes did not differ depending on the surgical adjunctive method employed. There were no differences in the visual prognoses, regardless of whether there was a persistent macular hole; however, recurrence was significantly higher in eyes with persistent macular holes. Therefore, further surgical treatment might be considered for eyes with persistent macular holes after MHRD surgery.

Abstract
Lay SummaryRecently, the use of the human amniotic membrane (hAM) has been extended to treat retinal disorders such as refractory macular holes, retinal breaks and dry and wet age-related macular degeneration. Not only the hAM has proved to be an excellent tool for repairing retinal tissue, but it has also shown a promising regeneration potential. This review aims to highlight the novel use of the hAM in treating retinal diseases. Although the hAM has been used in the ocular anterior segment reconstruction for more than 60 years, in the last 2 years, we have found in literature articles showing the use of the hAM in the retinal surgery field with interesting results in terms of tissue healing and photoreceptor regeneration.

Abstract
Background Despite the constant refinement of techniques and surgical aids, extremely large and refractory macular holes continue to have poor surgical outcomes with the current standard of care. The objective of the present study is to assess the anatomical and functional outcomes, as well as the structural change through time, of the optical coherence tomography of patients with refractory macular holes treated with a full-thickness autologous retinal transplant. Methods Prospective, case series. We include patients with a clinical diagnosis of refractory macular holes with a minimum diameter of at least 500 µm. All the patients had a comprehensive ophthalmological examination, which included a best-corrected visual acuity assessment, fundus examination, and optical coherence analysis. All the patients underwent a 23-gauge pars plana vitrectomy with a full-thickness retinal transplant and silicone oil tamponade (5000 cs<). Follow-up was done at 1, 3, 6, and 12 months. Statistical analysis was done with a test for repeated measurements and Bonferroni correction, with an alpha value of 0.05 for statistical significance and a Mann-Whitney U test for nonparametric continuous variables. Results We enrolled 13 eyes from 13 patients (mean age: 67.15 years) with refractory macular holes, with a mean base diameter of 1615.38 ± 689.19 µm and a minimum diameter of 964.08 ± 709.77 µm. The closure rate after 12 months of follow-up was 76.92%. Six patients with a closed macular hole at the end of the follow-up had complete recovery of the myoid/ellipsoid layer. The remaining showed a 44.9% reduction of the initial gap. Most patients formed a pseudofovea and normalization of the internal retinal layers. Despite a positive trend toward visual recovery (p = 0.034), after the correction of the alpha value, the change lost its statistical significance. During follow-up, one patient developed mild proliferative vitreoretinopathy and epiretinal membrane without anatomical or functional consequences. Conclusions An autologous full-thickness retinal transplant may improve the anatomical and structural outcome of patients with refractory macular holes. The full safety profile of this new technique is still unknown. More studies are needed in order to assess functional changes through time.

Abstract
The failed macular hole is a full-thickness defect involving the fovea that fails to close despite 1 or more surgeries. While many surgical options have been proposed to manage it, none of these guarantee complete anatomical success and satisfactory visual recovery. We report postoperative outcomes on 36 patients affected by failed macular hole, treated with a human amniotic membrane plug transplant. Follow-ups were performed with a standard ophthalmological examination and with advanced multimodal diagnostic imaging. Anatomical closure was achieved at 3 months in all patients. Mean best-corrected visual acuity improved statistically significantly at 6 months (p < 0.05). Through microperimetric tests, we assessed a partial recovery of the macular sensitivity on the edges of the plug. Analyzing SD-OCT images, we reported a tissutal ingrowth above the plug, and its segmentation into layers, mimicking normal retinal architecture. OCT-Angiography images non invasively analysed the retinal parafoveal capillary microvasculature; the elaboration of Adaptive Optics images showed the presence of photoreceptors at the edges of the plug. This work demonstrates not only the complete anatomical success of our technique, but also remarkable functional results, and opens the door to a greater understanding of modifications induced by the presence of a human amniotic membrane plug.

A large array of preoperative, intraoperative, and postoperative data was collected. Two masked reviewers graded OCT images. Multivariate statistical analysis and subgroup analysis were performed. MAIN OUTCOME MEASURES Macular hole closure rate, visual acuity (VA), external limiting membrane and ellipsoid zone (EZ) band integrity, and alignment of neurosensory layers (ANL) on OCT. RESULTS One hundred thirty ART surgeries were performed by 33 vitreoretinal surgeons worldwide. Patient demographics were: mean age of 63 ± 6.3 years, 58% female, 41% White, 23% Black, 19% Asian, and 17% Latino. Preoperative VA was 1.37 ± 0.12 logarithm of the minimum angle of resolution (logMAR; Snellen equivalent, approximately 20/500), which improved significantly to 1.05 ± 0.09 logMAR (Snellen equivalent, approximately 20/225; P < 0.001) after surgery (mean follow-up, 8.6 ± 0.8 months). Autologous retinal transplantation was performed for primary MH repair in 27% of patients (n = 35), for refractory MH in 58% of patients (n = 76; mean number of previous surgeries, 1.6 ± 0.2), and for MH-RRD in 15% of patients (n = 19). Mean maximum MH diameter was 1470 ± 160 μm, mean minimum diameter was 840 ± 94 μm, and mean axial length was 24.6 ± 3.2 mm. Overall, 89% of MHs closed (78.5% complete; 10% small eccentric defect), with a 95% closure rate in MH-RRD (68.4% complete; 26.3% small eccentric defect). Visual acuity improved by at least 3 lines in 43% of eyes and by at least 5 lines in 29% of eyes. Reconstitution of the EZ (P = 0.02) and ANL (P = 0.01) on OCT were associated with better final VA. Five cases of ART graft dislocation (3.8%), 5 cases of postoperative retinal detachment (3.8%), and 1 case of endophthalmitis (0.77%) occurred. CONCLUSIONS In this global experience, patients undergoing ART for large primary and refractory MHs and MH-RRDs achieved good anatomic and functional outcomes, with low complication rates despite complex surgical pathologic features.

Abstract
The human amniotic membrane (hAM) has lately demonstrated interesting potential in its retinal applications. Nowadays, the treatment of persistent macular holes is still a challenge. In this paper, we present a case of a hAM plug used to treat a persistent macular hole, with the purpose of highlighting the critical issues of this new surgical procedure. We performed a 23-G pars plana vitrectomy and inserted a hAM plug (diameter of 1.5 mm) under the neuroretinal margins of the hole (diameter of 657 μm). A complete ophthalmic examination with the assessment of best-corrected visual acuity (logMAR units, ETDRS letter score) and optical coherence tomography (OCT) scans were collected at 1, 4, 6, and 10 weeks after surgery. Visual acuity changed from logMAR 1.0 (1) preoperatively to logMAR 1.0 (2), 1.0 (4), 0.9 (9), and 0.9 (10) at 1, 4, 6, and 10 weeks of follow-up, respectively. The 1 week postoperative OCT did not show neuroretinal adhesion over the plug, but the following visits showed reattachment of the margins with partial neuroretinal ingrowth. These findings suggest that the correct adaptation of the size of the hAM plug to the macular hole is essential to allow the anatomical closure of the hole and potential functional results.

Abstract
Background: To analyse the feasibility and efficacy of a novel autologous plasma rich in growth factor (PRGF) preparation as adjuvant to pars plana vitrectomy and internal limiting membrane peel in high myopic full-thickness macular hole (FTMH). Methods: Single-centre, single-surgeon retrospective chart review of consecutive patients with high myopic FTMH who underwent surgery with a minimum follow-up of 12 months. Patients were divided in group 1 (naïve) and group 2 (persistent). Quantitative and qualitative variables were analysed, compared among groups and correlated with best corrected visual acuity (BCVA). Results: Postoperatively, FTMH resolved in 28/31 eyes in group 1 (90%) and in 10/11 eyes in group 2 (91%), without significant differences ( p = 0.954). None of the preoperative anatomical variables analysed showed significant association with preoperative BCVA. Intraoperatively, no significant complications were registered. Postoperatively, BCVA improved significantly in the studied population ( p < 0.001). Preoperative factors associated with better postoperative BCVA were the presence of intraretinal cystoid spaces ( p = 0.028) and elevated FTMH borders ( p = 0.005). Preoperative dome-shaped macula was associated with significantly worse postoperative BCVA ( p = 0.049). Conclusion: The use of PRGF as adjuvant to vitrectomy showed to be reproducible, straightforward and efficient, with primary anatomical success rate comparable to other surgical approaches and lower risk of complications.

Abstract
PURPOSE To present a modified surgical technique, based on a combination of human amniotic membrane (hAM) patch and autologous Platelet-rich plasma (PRP) in a case of recurrent retinal detachment (RRD) due to a perivascular retinal hole over an area of staphyloma in an eye with pathologic myopia. METHODS Presenting the surgical technique with the disposal of surgical video. After performing 23-gauge pars plana vitrectomy (PPV) the hAM patch was inserted under the neuroretina through the perivascular hole and PRP was injected on top to speed up the closure of the hole. To complete the surgical procedure High Viscosity Silicon oil (5000cst) was used as tamponade. The patient was prescribed to maintain a face-down position for the first 3 days after the operation. Follow-up was evaluated through Optical coherence tomography (OCT) scans. RESULTS The 3 days postoperative OCT showed a flat retina with the filling of the myopic staphyloma. The hAM patch was well positioned and the retinal hole could not be identified. At 6 weeks from intervention, the site of the retinal hole at OCT scan was covered by new tissue. Silicone oil was removed 3 months later with no recurrence. CONCLUSION hAM transplantation is a novel technique in case of retinal detachment recurrences to seal retinal holes over high myopic chorioretinal atrophy. The adjunctive use of PRP and high viscosity silicon oil allows to reducing the standard face-down positioning timing, representing a valid solution for elderly patients who have difficulties maintaining the position for long periods.

Abstract
Recently, the use of the human amniotic membrane (hAM) has been extended to treat retinal disorders, such as macular holes that failed to close and retinal tears. The hAM has demonstrated the induction of a recovery process of the external retinal layers involving the external limiting membrane (ELM) and the ellipsoid zone (EZ). After that, the application of the hAM for retinal pathologies was extended to large macular tears, high myopic retinal detachment associated with MH, paravascular tears, serous macular detachment associated with optic pit, complicated retinal detachment and advanced age-related macular degeneration (AMD). The hAM has shown a potential in repairing retinal tissue through a regeneration process. This review aims to highlight the use of the hAM in various vitreo-retinal surgical fields, and to confront it with other cutting-edge surgical techniques used to treat challenging vitreo-retinal pathologies.

Comparison between Cryopreserved and Dehydrated Human Amniotic Membrane Graft in Treating Challenging Cases with Macular Hole and Macular Hole Retinal Detachment. J Ophthalmol 2020; 2020:9157518. [PMID: 32724671 PMCID: PMC7364261 DOI: 10.1155/2020/9157518] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 06/12/2020] [Accepted: 06/18/2020] [Indexed: 12/30/2022] Open
Abstract
Purpose To evaluate the surgical outcomes of cryopreserved and dehydrated human amniotic membrane (hAM) graft transplantation for macular hole (MH) and macular hole retinal detachment (MHRD) repair. Materials and Methods This retrospective, interventional case series was conducted in two hospitals. Two types of hAM grafts, namely, the dehydrated form (AmnioGen, HCT Regenerative, Taiwan) and the cryopreserved form (AmnioGraft, Bio-Tissue, Miami, FL), were consecutively used in MH surgeries. Anatomical and functional outcomes between the 2 types of hAM grafts were compared. Results Seventeen patients (mean age: 62.1 ± 10.0 years, 9 (52.9%) males) were enrolled. Of them, 11 patients had persistent MH, 3 had MH without prior surgery, and 3 had MHRD. A cryopreserved hAM graft was used in 10 patients, and a dehydrated hAM graft was used in 8 patients. One patient used a cryopreserved hAM in the first MH surgery and a dehydrated hAM in the second surgery for extramacular hole with retinal detachment. After a 6-month follow-up, 13 (76.5%) patients had sealed MHs. The average visual acuity (VA) of cases with sealed MHs improved from 1.38 ± 0.62 to 1.12 ± 0.47 logMAR (p=0.03). In the other 4 cases with persistent MH, 3 had graft dislocation and 1 had a reopened MH with graft contraction. There were no significant differences in closure rate (80.00% vs. 71.43%, p=0.68) or VA improvement (0.19 ± 0.37 logMAR vs. 0.15 ± 0.41 logMAR, p=0.85) between the 2 kinds of hAM graft. Conclusion This preliminary case series showed that both cryopreserved hAM and dehydrated hAM are feasible alternative grafts for either persistent or recurrent MH. Both approaches have similar anatomical and functional outcomes.

Abstract
PURPOSE OF REVIEW Orthobiologics, including amniotic products, have been gaining interest in the past decade for the treatment of various orthopedic conditions including osteoarthritis. However, the use of biologics is varied and is currently available with minimal oversight or regulation. This review will assess the current state of research that utilizes amniotic products both in vitro and in vivo. RECENT FINDINGS Amniotic tissue derivatives have been shown to have positive effects in animal models for a variety of conditions. Clinical trials are limited with mixed outcomes, yet some recent studies suggest the rationale for continued investigation. While amniotic products appear promising in numerous animal studies, human clinical trials are still lacking. Future studies are needed to assess whether amniotic products have a role in the treatment of osteoarthritis and other orthopedic pathologies.
