Purpose: To report a case of complicated exposed scleral buckle in which amniotic membrane was used to repair the extremely thin sclera that showed the underlying choroid.
Methods: Interventional case report. A 65-year-old man presented to our Department with severe eye pain after retinal detachment repair with scleral buckling technique 7 years ago.
Results: Examination of the left eye revealed extrusion of the buckle with conjunctival and scleral erosion that allowed distinguishing the choroid. The buckle was removed and successful scleral repair was achieved through the use of amniotic membrane.
Conclusion: Amniotic membrane graft is a safe and useful scleral substitute that should be considered to cover scleral defects, in the absence of infection.

In the quest for an ideal wound healing material, human amniotic membrane (AM), tilapia skin collagen (TSC), and Centella asiatica (CA) have been studied separately for their healing potential. In this study, we formulated AM, TSC, and CA gel and studied their competency and wound healing efficacy in vivo. Gel was formulated using AM, TSC, CA, Carbopol 934, acrylic acid, glycerine, and triethanolamine and physicochemical properties e.

Objective: Chronic wounds are a common clinical problem that necessitate the exploration of novel regenerative therapies. We report a method to investigate the in vitro wound healing capacity of an innovative biomaterial, which is based on amniotic membrane-derived stem cells (AMSCs) embedded in an alginate hydrogel matrix. The aim of this study was to prepare an sodium alginate-based hydrogel, cross-linked calcium chloride (CaCl with the active ingredient AMSC (AMSC/Alg-H) and to evaluate its in vitro effectiveness for wound closure.

Previous studies have explored nanofat stimulating tissue regeneration and maturation, promoting remodeling through its rich content of growth factors and stem cells; however, comprehensive data on its use in full-thickness wounds remains limited. The aim of this study was to evaluate the effectiveness of combining nanofat with freeze-dried human amniotic membrane (FDHAM) for treating full-thickness wounds in a rabbit model. An animal experimental study using a post-test control group design was conducted.

Placenta tissue has biological advantages, including anti-inflammatory, anti-bacterial, anti-fibrotic formation, and immunomodulatory properties. The amnion membrane (AM) is an inner side membrane of the placenta that faces the fetus. The main sources of amnion are humans and animals, with bovine being one of the significant sources.

Introduction: The use of corticosteroid injections for short-term pain relief for knee osteoarthritis can have deleterious adverse effects. Amniotic tissue has shown promise in vitro; therefore, this study compared a morcellized injectable amniotic tissue allograft to corticosteroid injection.
Methods: Eighty-one patients with symptomatic severe knee osteoarthritis (Kellgren-Lawrence grade 3 to 4) were prospectively randomized to either a double-blinded single injection of BioDRestore (Integra LifeSciences; n = 39) or triamcinolone acetonide (n = 42).
