Fornix contracture is an obstacle for fitting a prosthesis in blind or enucleated patients, and may lead to disfigurement and psychological issues. This study evaluates the efficacy of amniotic membrane transplantation (AMT) for fornix reconstruction with the aim of better retention of the ocular prosthesis.
This non-comparative interventional case series includes eighteen blind eyes with fornix deformity in which a cosmetic prosthesis could not be retained. Various causative factors included symblepharon, cyst formation and fornix shortening after enucleation. AMT was performed along with correction of symblepharon, cicatrix release, and excision of the cyst with or without anchoring sutures to reform the fornix.
Mean fornix depth pre- and post-operation were 3.72 ± 0.69 and 7.13 ± 0.81 mm, respectively. Fornix deepening was achieved successfully in 15 cases (83.33%). Partial success was achieved in 1 case (5.66%); the remaining two cases (11.11%) were considered as failure despite repeat surgery. Both of these patients suffered from extensive symblepharon formation. Satisfactory results, i.e. formation of a deep fornix to hold the ocular prosthesis, could be achieved in 16 (89.99%) cases. There were no serious complications such as infection or graft rejection.
AMT can be a viable option for fornix reconstruction. It has a high success rate in subjects with blind eyes and moderate fornix shortening who are unable to retain an ocular prosthesis.
穹窿挛缩是失明或眼球摘除患者佩戴义眼的障碍,可能导致容貌毁损和心理问题。本研究评估羊膜移植(AMT)用于穹窿重建以更好地固定义眼的疗效。
本非对照性干预病例系列包括18只存在穹窿畸形且无法佩戴美容义眼的盲眼。各种病因包括睑球粘连、囊肿形成以及眼球摘除术后穹窿缩短。进行AMT的同时矫正睑球粘连、松解瘢痕并切除囊肿,有或没有采用锚定缝线以重建穹窿。
术前和术后穹窿平均深度分别为3.72±0.69mm和7.13±0.81mm。15例(83.33%)成功实现了穹窿加深。1例(5.66%)取得部分成功;尽管进行了再次手术,其余2例(11.11%)被视为失败。这两名患者均有广泛的睑球粘连形成。16例(89.99%)取得了满意的结果,即形成了较深的穹窿以固定义眼。没有发生感染或移植排斥等严重并发症。
AMT可作为穹窿重建的一个可行选择。对于无法佩戴义眼的盲眼且穹窿中度缩短的患者,其成功率较高。
