Amniotic membrane (AM), a very thin layer of the placenta is useful in treatment of a spectrum of ocular surface conditions including persistent non-healing epithelial defects, stromal ulcers, chemical burns, pterygium, and autoimmune ocular surface disorders (e.g. Stevens-Johnson syndrome, toxic epidermal necrolysis, ocular cicatricial pemphigoid). AM provides a natural surface and nutrition for growth of the epithelium, which is the surface layer of the cornea and conjunctiva. AM is transplanted on to the surface of the eye to enhance healing and restore ocular surface.
