异体巩膜修补大范围巩膜溶解的疗效观察

目的 探索用异体巩膜移植修补大范围巩膜溶解的临床疗效。方法 对巩膜扣带术后巩膜大范围缺血性坏死溶解2例（2只眼）和上半部角巩膜葡萄肿穿孔伴眼内炎1例（1只眼）施行同种异体巩膜瓣移植，随访5～12个月。观察患者视力、巩膜植片、视网膜、眼压及其并发症等。结果 2例患者视力均较术前提高,1例患者视力与术前相同。巩膜植片无溶解，周围被纤维组织包裹，略呈弧形隆起，并有新生血管长入，形成加厚的“新巩膜”。视网膜在位，眼压正常。结论 用异体巩膜移植修补大范围巩膜溶解，较大的植片能与宿眼的巩膜相融合且无排斥反应，能有效维持眼压、眼球外观，尽可能挽救患者的视力。

Allogeneic scleral transplantation for large scleral lyric necrosis

Objective To investigate the therapeutic effect of allogeneic scleral graft to repair large scleral lytic necrosis. Methods Allogeneic scleral transplantation were performed in 2 cases (2eyes) with scleral Iytic necrosis after scleral buckling and 1 case (1 eye) with penetrating corneoscleral staphyloma. All cases were followed up for 5 months to 24 months by observing visual acuity,scleral graft, retina, intraocular pressure (IOP) and possible complications. Results Visual acuity were improved in 2 cases, remained in 1 case; the sclearl grafts were wrapped up by vaculized fiber tissue and formed a new thick sclera, no dissolving were found.The retinas were flat, IOP was controlled in normal level. Conclusions Allogeneic scleral graft can fuse with host sclera without rejection, repair poor or penetrating sclera and save visual acuity.
