PURPOSE
To describe 2 cases of corneal perforation associated with pellucid marginal degeneration (PMD) and subsequent successful management with crescentic lamellar keratoplasty.
METHODS
Two cases are discussed along with the relevant literature.
RESULTS
Both patients presented with spontaneous corneal perforations and associated features consistent with PMD. In both cases, there was fellow eye evidence of PMD, and 1 of the patients was already known to our unit with this diagnosis. Initial conservative measures were unsuccessful, and both patients underwent crescentic lamellar keratoplasty as the definitive surgical management with a good visual outcome.
CONCLUSIONS
Crescentic lamellar keratoplasty is an effective technique for the management of this rare complication of PMD.
目的
描述2例与透明边缘变性（PMD）相关的角膜穿孔病例，以及随后采用新月形板层角膜移植术成功治疗的情况。
方法
讨论2例病例及相关文献。
结果
2例患者均出现自发性角膜穿孔，并伴有与PMD一致的相关特征。2例患者对侧眼均有PMD证据，其中1例患者本单位已确诊为此病。初始保守治疗未成功，2例患者均接受了新月形板层角膜移植术作为最终手术治疗，视觉效果良好。
结论
新月形板层角膜移植术是治疗PMD这种罕见并发症的有效技术。
