0引言角膜边缘变性为一较少见双眼慢性进行性病变,亦称为角膜周边部沟状变性或扩张性角膜边缘营养不良,由Terrien(1900年)首次报告,其发病原因迄今尚未明了,目前无有效药物治疗。板层角膜移植能控制病情的进一步发展,预防角膜穿孔。角膜边缘变性的患者,于我院行角膜边缘变性切除联合部分板层角巩膜移植术,术后远期疗效观察效果良好,现报道如下。1临床资料我院收集2005-10/2011-03来我院眼科就诊的角膜边缘变性患者16例19眼。男5例7眼,女11例12眼。年龄14～64(平均35.6)岁。病史1～25a,病变处角膜菲薄,
0 Introduction Corneal limbal degeneration is a rare, chronic progressive lesion of both eyes, also known as periaqueductal dilated or dilated corneal marginal malnutrition, first reported by Terrien (1900), the etiology of which has not yet been elucidated so far No effective drug treatment. Lamellar keratoplasty can control the further development of the disease, prevent corneal perforation. Corneal limbal degeneration in patients with corneal limbal debridement combined with partial lamellar angle scleral graft surgery, postoperative long-term efficacy of effective observation, are reported below. 1 clinical data collected in our hospital from 2005-10 / 2011-03 to our hospital ophthalmology patients with corneal edge degeneration 16 cases 19 eyes. 5 males and 7 females, 11 females and 12 eyes. Age 14 ~ 64 (average 35.6) years old. History of 1 ~ 25a, corneal lesions thin,
