AIMS: To evaluate the efficacy of amniotic membrane transplantation (AMT) for ocular surface reconstruction. METHODS: 10 consecutive patients who underwent AMT were included. The indications were: group A, cases with persistent epithelial defect after corneal abscess (n = 1), radiation (n = 1), or chemical burn (n = 3); group B, cases with epithelial defect and severe stromal thinning and impending or recent perforation, due to chemical burn (two patients, three eyes) or corneal abscess (n = 2); group C, to promote corneal epithelium healing and prevent scarring after symblepharon surgery with extensive corneo-conjunctival adhesion (n = 1). Under sterile conditions amniotic membrane was prepared from a fresh placenta of a seronegative pregnant woman and stored at -70 degrees C. This technique involved the use of amniotic membrane to cover the entire cornea and perilimbal area in groups A and B, and the epithelial defect only in group C. RESULTS: The cornea healed satisfactorily in four of five patients in group A, but the epithelial defect recurred in one of these patients. After AMT three patients underwent limbal transplantation and one penetrating keratoplasty and cataract extraction. In group B amniotic membrane transplantation was not helpful, and all cases underwent an urgent tectonic corneal graft. Surgery successfully released the symblepharon, promoted epithelialisation and prevented adhesions in the case of group C. CONCLUSION: AMT was effective to promote corneal healing in patients with persistent epithelial defect, and appeared to be helpful after surgery to release corneo-conjunctival adhesion. Most cases required further surgery for visual and ocular surface rehabilitation. Amniotic membrane used as a patch was not effective to prevent tectonic corneal graft in cases with severe stromal thinning and impending or recent perforation. 相似文献

Transplantation of amniotic membrane and limbal autograft for patients with recurrent pterygium associated with symblepharon 总被引:25,自引:0,他引:25 下载免费PDF全文
AIM—Treatment of recurrent pterygium associated with symblepharon requires both suppression of fibrosis and reconstruction of limbal barrier. To achieve this, human amniotic membrane was transplanted and limbal autografts performed.
METHODS—Four patients with severe symblepharon resulting from multiple surgeries for pterygium were treated. Human amniotic membrane was obtained at caesarean section and preserved until surgery. After excision of the fibrous tissues, the amniotic membrane was placed on the sclera, and a limbal autograft transplantation was performed using limbal tissues taken from the affected eye.
RESULTS—Recurrence of symblepharon was not observed in any of the patients and significant suppression of the subconjunctival fibrosis was achieved. Ocular movement improved in all cases. Complete remission of pterygium regrowth occurred in three cases, and a slight (about 1 mm) recurrence occurred in one case. The limbal donor site showed the presence of mild depressions without the formation of pseudopterygium.
CONCLUSION—Transplantation of human amniotic membrane with a limbal autograft appears to be a promising surgical treatment for reconstructing the ocular surface in patients with recurrent pterygium associated with symblepharon.

BACKGROUND: The amniotic membrane is a useful tool in the management of several ocular surface diseases. Despite numerous studies, standardization of the use of the membrane and of outcome measures is lacking. Herein, the authors' results of amniotic membrane transplantation (AMT) in ocular surface reconstruction against defined outcome measures are reported. METHODS: A retrospective case study of 74 consecutive procedures (58 patients) performed against predefined outcome measures. The cases were divided into three groups. Group A AMT in the presence of stem cell loss (32 procedures), Group B AMT without stem cell loss (24 procedures) and Group C AMT for conjunctival reconstruction (18 procedures). The outcomes were evaluated against defined criteria based on the purpose (patch or graft) and objective for use of the membrane. Results were analysed by defining the outcomes as success, partial success or failure. RESULTS: Unequivocal success of the procedure was observed in 22% in Group A, 62.5% in Group B and 50% in Group C. AMT was significantly more successful in the presence of functioning stem cells (P = 0.01). In Group A acute and subacute cases (less than 3 months) needed more procedures compared with chronic cases (P = 0.02). In Group C, results were comparatively worse when AMT was used in progressive cicatrizing conditions. CONCLUSION: Use of AMT can be associated with a significant number of failures. It provides a useful alternative for specific indications where its use should be encouraged. It is important to define criteria for success in order to accurately evaluate efficacy. 相似文献
