异种巩膜作加压材料治疗视网膜脱离

采用异种（猪）巩膜作加压材料治疗35例（35只眼）视网膜脱离，术后近期全部视网膜复位。随访中有5例复发，其中4例第2次手术，再复位2例，治愈率91.4%.经3年以上随访，术后均无明显免疫排斥反应、加压物排出、暴露及感染发生。猪巩膜具有人巩膜相似的优良特性，可代替异体（人）巩膜应用于眼科临床。（中华眼底病杂志，1994，10：207-209）

TREATMENT OF RETINAL DETACHMENT WITH XENOGENEIC SCLERA AS PRESSOR MATERIAL

e demonstrate 35 cases of retinal detachment in which the patients received treatmentwith xenogeneic(porcine)sclera as pressor material. AlL the patients improved with retinalreplacement after initial operation. There are 5 relapsing cases in which 4 patients were re-operated and the retinas were reattached in 2 cases. So far the total curative percehtage was91.4 in this series. After a period of three-year follow-up,none of the patient showed appar-ent postoperative complication of rejection reaction,discharge,exposure and infection. Thesefindings suggest that porcine sclera has excellent characteristic,similar to human sclera,andmay be used in ophthalmologic surgery as a substitute of homologous(human)sclera.
