目的 探索同种异体巩膜在视网膜脱离手术中的应用及疗效。方法 用异体巩膜作充填材料和环扎材料 ,具体方法为 :1.巩膜外加压术 ;2 .巩膜层间加压术 ;3.巩膜环扎术。结果 共手术 12例 ,术后均未发生感染、排斥反应及局部刺激症状 ,其中 9例网膜复位 ,3例裂孔封闭不佳 ,未复位 ,手术有效率为 75 %。结论 异体巩膜主要成份为胶原纤维 ,细胞成份少 ,抗原性小 ,组织柔软、富有弹性和一定伸缩性 ,是一种较为理想的生物材料 ,可作为治疗视网膜脱离的充填和环扎材料
Objective To explore the application of allogeneic sclera in retinal detachment surgery and its curative effect. Methods Allogeneic sclera was used as filling material and cerclage material. The specific methods were as follows: 1. scleral buckling; 2. scleral intercalation; 3. scleral cerclage. Results A total of 12 cases were operated on. No infection, rejection and local irritation occurred after surgery. Among them, 9 cases underwent reattachment and 3 cases had poorly closed hiatus without repositioning. The operative efficiency was 75%. Conclusion The main component of the sclera is collagen fibers, less cellular components, antigenicity is small, soft tissue, flexible and scalability, is an ideal biological material, can be used as a treatment of retinal detachment filling and cerclage material
