[Amniotic membrane transplantation in herpetic corneal infections]

Abstract

Severe infectious corneal ulceration such as herpetic stromal keratitis commonly causes loss of vision and may lead to blindness. Treatment depending on the underlying disease includes antimicrobial medication and the development of surgical strategies to restore the integrity of the corneal ocular surface. Ulcerative herpetic stromal keratitis and/or neurotrophic keratopathy with the risk of corneal perforation are still clinically challenging conditions in ophthalmic surgery of the ocular surface. Since the introduction of newly developed preservation methods, amniotic membrane (AM) functioning as a basement membrane substitute has gained widespread popularity in ocular surface reconstruction. Various ways of clinical application such as the use of AM as a graft, patch or culture substrate and carrier system to expand ocular surface epithelia have been recently reported. In this article, the basis and clinical application of amniotic membrane transplantation for the management of corneal infections with Herpes simplex and Herpes zoster virus are reviewed.
