摘要：

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. © 2008 by Lippincott Williams & Wilkins.
