摘要
目的:研究穿透性角膜移植术后角膜后膜形成的形态改变。方法:对45例部分穿透性角膜移植术后出现角膜后膜的角膜植片进行病理观察。结果:角膜后膜形成与创口对合不佳、排斥反应、角膜上皮植入、前房出血和虹膜前粘连有关。结论:宿主角膜实质纤维细胞增生通过后弹力层创口长入角膜后、炎症渗出物内的单核细胞和残存的内皮细胞向纤维细胞化生为穿透性角膜移植术后角膜后膜形成的主要机制。眼科学报1997;13:82～84。
Purpose: To observe the clinicopathologic changes of retrocorneal membrane after keratoplasty.
Methods: Light microscope and histochemical technique were used. Results :The clinicopathologic review of 108 unsuccessful keratoplasties revealed the presence of 45 retrocorneal membrane, which seems to depend on the wound abnormality, rejection of corneal transplantion, epithelium in growth, hyphema, and iris is synechias.
Conclusion :The retrocorneal membrane derives from the host corneal stromal kerato-cytes and the metaplasia of corneal endothelial cells and monocytes. Eye Science 1997; 13:82-84.
