Abstract In the field of Ophthalmology, Amniotic membrane transplantation has been first used by De Roetth in 1940 to treat conjunctival defects However De Roetth used ”live” human amniotic membrane which contained live cells, and thus was accompanied by undesirable aJlograft rejectipns. Recently, the technique of preparation and preservation has been revised, with cryopreservation of the membrane at - 80C degrees. This has lead to marked improvement in the post operative results of Amniotic membrane transplantation in various ocular surface disorders viz: recurrent pterygium with symblepharon, persistent epithelial defects of the cornea, ocular cicatricial pemphigoid, chemical and thennal injuries and in covering large conjunctival defects following the surgical removal of large conjunctival masses. The transplanted membrane tissue was found to take easily and was not accompanied with any aJlograft rejections following the recently described technique of preparation and cryopreservation. This has thus offered a major contribution to the treahnent of many challenging cases |
