title: Amniotic membrane transplantation for ocular surface pathology: long-term results.
abstract: Amniotic membrane transplantation has been used for >90 years for cutaneous and mucous lesions for regeneration of tissues. In recent years its effectiveness has been demonstrated in the treatment of diseases of the ocular surface. We present our experience with 53 amniotic membrane transplantations for different ocular pathologies with two different forms of implantation. The 53 cases were divided into three groups according to pathology and type of implant. Group 1 included 24 eyes with amniotic membrane grafts after resection of extensive conjunctival lesions. Group 2 included 19 eyes with amniotic membrane grafts for corneal pathology, and group 3 consisted of 10 eyes with amniotic membrane patches for corneal epithelial defects without ulceration. No intra- or postoperative complications were observed during an average follow-up period of 32 months (24-48 months). Group 1 demonstrated rapid healing of the lesions with minimal scarring in all cases. In group 2 a favorable response was observed in 16 of 19 cases. In group 3 complete healing was achieved in only 3 of 10 cases, and the time for which the graft remained was related to the success of the treatment. The primary intention was to achieve prolonged fixation of the implant. Finally, amniotic membrane transplantation is a safe and effective technique for the treatment of different pathologies of the ocular surface. After the resection of extensive conjunctival lesions it is currently the preferred treatment. In corneal pathology, it represents an additional therapeutic alternative when conservative medical treatments fail.
