摘 要:目的分析行再次穿透性角膜移植(repeat penetrating keratoplasty,RPK)患者的原发病以及再次角膜移植的直接原因。方法调查1999年1月1日~2008年12月31日在青岛眼科医院和山东省眼科医院接受穿透性角膜移植的患者资料,对其中行RPK患者的资料进行回顾性分析,分析RPK患者的原发病和RPK的直接原因以及高危受者RPK的直接原因。结果10年间共有2922例患者(3455只眼)接受了穿透性角膜移植手术,其中接受RPK共206例患者(215只眼)。RPK受者中男性148例,女性58例,平均年龄(39.2±17.6)岁。原发病依次为单纯疱疹病毒性角膜炎(19%)、化脓性角膜炎(18%)、角膜裂伤(14%)、角膜烧伤(13%)、大泡性角膜病变(11%)、角膜变性或营养不良(9%)、角膜白斑(7%)、圆锥角膜(6%)、植片混浊(2%)、其他(1%)。RPK的直接原因依次为角膜移植片慢性失功(45%)、移植角膜排斥反应(27%)、角膜移植片溃疡(18%)、原发病复发(7%)、其他(3%)。其中高危受者RPK的前两位原因分别为移植角膜排斥反应(46%)和角膜移植片慢性失功(31%);非高危受者RPK的前两位原因分别为角膜移植片慢性失功(60%)和角膜移植片溃疡(17%)。结论RPK受者原发病以感染性疾病为主;排斥反应和角膜移植片慢性失功造成的角膜移植片混浊分别是高危和非高危受者接受RPK的主要原因。Objective To investigate the major causes of repeat penetrating keratoplasty (PK). Methods Clinical data of patients undergoing PK in Qingdao Eye Hospital and Shangdong Eye Hospital between January 1 st 1999 and December 31 st 2008 were investigated to retrospectively analyze primary diseases and direct causes for repeat PK, especially in the high-risk corneal transplantation group. Results A total of 2922 patients ( 3455 eyes ) were investigated, among which 206 patients (215 eyes) received repeat PK. The patients undergoing repeat PK included 148 men and 58 women, aging from 4 to 89 years,with a mean age of (39.2 ± 17.6) years. The primary diseases of first PK were herpes simplex keratitis ( 19% ) , suppurative keratitis ( 18% ) , corneal trauma ( 14% ) , corneal burns ( 13% ) , bullous keratopathy ( 11% ) , corneal dystrophy and degeneration (9%), corneal scar (7%), keratoconus (6%), graft failure (2%), and others (1%). The direct causes of repeat PK were chronic corneal allograft dysfunction (CCAD,45%) , graft rejection (27%), graft ulcer (18%), recurence of primary diseases ( 7% ) , and others ( 3% ). The top 2 causes of repeat PK were graft rejection (46%) and chronic corneal allograft dysfunction (CCAD, 31% ) in the high-risk corneal transplantation and CCAD (60%) and graft ulcer (17%) in the non-high-risk corneal transplantation. Conclusions The main primary diseases for repeat PK are infectious diseases. The leading causes of repeat PK were CCAD and graft rejection in the non-high-risk and high-risk corneal transplantation, respectively.
