Amniotic membrane transplantation in ocular surface disorders.
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. Amniotic membrane transplantation can be used in a number of conditions eg, as a graft to replace damaged ocular surface stromal matrix or as a patch to prevent unwanted inflammatory insults from gaining access to the damaged ocular surface. Amniotic membrane can be utilised in persistent of recurrent corneal epithelial and stromal defects; in cases of corneal perforation due to ulcer or melting; after conjunctival excision for acquired melanosis, neoplasia, etc; in cases of pemphigoid, Stevens-Johnson syndrome, chemical bums; in cases of symblepharon, in dry eyes or in large leaking filtering blebs.
