BACKGROUND Amniotic membrane transplantation (AMT) has a long tradition in ophthalmic surgery and has become very popular recently because of newly developed methods of tissue preservation. METHODS We selectively review the literature on recent developments, mechanisms of action, and established indications of AMT in the treatment of various diseases of the ocular surface. We searched the Pub...
PURPOSE To establish the effectiveness of amniotic membrane transplantation (AMT) in relieving pain and discomfort in patients with painful bullous keratopathy and its role in improving vision in eyes with visual potential. METHODS Seven eyes of seven consecutive patients with painful corneal conditions were included in a retrospective interventional noncomparative case series performed at Ma...
Background and Objective: Though amniotic membrane has recently been introduced as a natural tissue with anti-cancer properties, there are inadequate studies about involved mechanisms. In this study, the effect of amniotic membrane culture supernatant on viability of cancer cells via applying different doses was evaluated. Apoptosis as a possible mechanism of inducing cancer cell death by amnio...
PURPOSE To determine the clinical significance of postoperative conjunctival inflammation noted at the third or fourth week after intraoperative application of mitomycin C and amniotic membrane transplantation for pterygium. METHODS This retrospective study included 27 eyes of 23 patients with primary (n = 12) or recurrent (n = 15) pterygia. All cases were operated by extensive removal of sub...
OBJECTIVE To report our pediatric experience with amniotic membrane transplantation for ocular surface and forniceal reconstruction. METHODS Retrospective case review of children who underwent superficial keratectomy, symblepharon lysis, and forniceal reconstruction using amniotic membrane transplantation. The underlying diagnosis, visual acuity, level of discomfort at first and last visits, ...
The term ocular surface disorders indicate a close relationship between the conjunctival and corneal epithelium in many corneal and external diseases. The human amniotic membrane has a thick basement membrane and an avascular stromal matrix and its first ophthalmic use was reported by deRoth for conjunctival surface reconstruction. It was subsequently used for different ophthalmic reasons. Amni...
INTRODUCTION The management of Mooren's ulcer can be a challenge for clinicians. OBJECTIVE To report a case of Mooren's ulcer treated with amniotic membrane transplantation supplemented with autologous serum eye drops. CASE REPORT A 22-year-old male presented with history of pain, redness, watering and diminution of vision of the right eye for one year. Examination of his eyes revealed the ...
AIM To examine the efficacy, safety, and long term outcomes of amniotic membrane transplantation for corneal surface reconstruction in cases of partial limbal stem cell deficiency. METHODS 17 eyes of 15 patients with partial limbal stem cell deficiency underwent superficial keratectomy of the conjunctivalised corneal surface followed by amniotic membrane transplantation. Cases were followed u...
