PURPOSE
We present a case of advanced bilateral pellucid marginal degeneration (PMD) with unilateral hydrops to show the unique properties of Scheimpflug imaging and its ability to display the clinical and topographic findings of PMD not seen on traditional placido-based topography.
METHODS
Case report and literature review.
RESULTS
A 51-year-old man was referred with a presumptive diagnosis of bilateral keratoconus with unilateral hydrops. Complete topographic evaluation showed a band of inferior thinning adjacent to the limbus and a Scheimpflug cross-sectional image consistent with PMD.
CONCLUSIONS
We show the value of Scheimpflug-based topography and pachymetry maps to accurately depict the unique disease characteristics of PMD.
目的
我们报告一例晚期双侧透明边缘变性（PMD）合并单侧角膜水肿的病例，以展示眼前节光学相干断层扫描（Scheimpflug）成像的独特特性及其显示传统基于普拉西多盘的地形图上未见的PMD临床和地形学表现的能力。
方法
病例报告及文献复习。
结果
一名51岁男性因双侧圆锥角膜合并单侧角膜水肿的初步诊断前来就诊。完整的地形图评估显示角膜缘附近有一条下方变薄带，眼前节光学相干断层扫描（Scheimpflug）横断面图像符合PMD表现。
结论
我们展示了基于眼前节光学相干断层扫描（Scheimpflug）的地形图和角膜厚度测量图在准确描绘PMD独特疾病特征方面的价值。
