Introduction We described a case of initial unsuccessful outcome of failed macular hole treated with amniotic membrane, that resolved after amniotic membrane exchange and silicone oil injection. Case Description a woman affected by a high myopic macular hole that had failed to close after multiple surgeries, had been treated using an amniotic membrane graft and 20% sulfur hexafluoride but, after the gas reabsorption, the macular hole was still open, and the amniotic membrane. A second surgery with a second amniotic membrane patch and silicone oil was carried out. Two weeks after the procedure the macular hole closed, and the final visual acuity improved from 20/400 to 20/100. Conclusions In this case, a second surgery, using a new amniotic membrane graft and a longer-lasting endotamponade, closed the hole and improved the visual acuity.

PurposeTo report the surgical outcome and postoperative hypopigmented change around fovea among patients with high myopia who received human amniotic membrane (hAM) graft transplantation for macular hole (MH).MethodThis retrospective, interventional case series included 10 eyes of 10 consecutive patients (5 (50%) male) with high myopia (axial length over 26.5 mm) who received hAM graft to treat persisted or chronic MH with or without retinal detachment in two hospitals. Postoperative parafoveal atrophy was identified with colour fundus picture and structure optical coherent tomography. Baseline characteristics and short-term visual outcome were analysed.ResultsThe preoperative mean (±SD) axial length and MH diameter were 29.9 (±1.8) mm and 881.8 (±438.5) μm, respectively. After hAM transplantation, seven (70%) eyes had complete MH closure and the mean best-corrected visual acuity (BCVA) improved from 1.26 (±0.48) logarithm of minimal angle of resolution (logMAR) before operation to 1.11 (±0.44) logMAR on the last visit (p=0.074). Patchy atrophy-like depigmentation developed around the MH lesion in four (40.0%) eyes as early as in the first month after surgery. None of them had visual worsening. In terms of demographics, axial length, MH size, ocular history, preoperative BCVA and postoperative BCVA, there was no significant difference between those with and without the parafoveal atrophy. No graft rejection and inflammation happened during the follow-up.ConclusionParafovea atrophy, a rare complication in the conventional MH surgery, was observed in 40% of eyes with highly myopic MH after hAM graft transplantation. The pathogenesis and long-term consequence need further investigations.

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.

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 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.
