摘    要:目的探讨后巩膜加固术的作用机制.方法24只家兔分为4组,以人巩膜为材料行插片法后巩膜加固术,分别于术后2,4,12和24周取标本,行肉眼观察及光镜、透射电镜检查.结果植片与宿主巩膜融合为一,"新巩膜"的厚度和硬度明显增加,抵抗力增强;局部血液循环改善.结论后巩膜加固术能加强薄弱的后部巩膜,改善眼球后部的血液供应,从而达到治疗病理性近视眼的目的.

关 键 词:后巩膜加固术  近视治疗

Abstract:Objective: To investigate the mechanism of posterior scleral reinforcement. Methods: 24 white rabbits were randomly divided into 4 groups, each group including 6 rabbits. The scleral reinforcement by means of human sclera grafting was performed on the left eye of each rabbit. These animals were killed at 2, 4, 12 and 24 weeks after surgery, respectively. The specimens were harvested and detected by gross examination, light and electron microscope. Results: At 24 weeks postoperatively, the graft healed with host sclera entirely. The "new sclera" was thicker and harder than before. The blood flow in the posterior parts of the globe increased. Conclusions: The scleral reinforcement prevents myopia progression by strengthening the thin posterior sclera and increasing regional blood.
Keywords:posterior scleral reinforcement  myopic treatment
