目得：目的：评价眼反应分析仪的圆锥角膜匹配指数（KMI）和圆锥角膜匹配概率（KMP）分类对圆锥角膜可疑眼的诊断能力。单位：德国洪堡萨尔兰大学临床眼科。设计：对比病例系列。方法：比较圆锥角膜可疑眼和正常眼的KMI和KMP参数。计算所有可疑眼的定量圆锥角膜百分比指数。根据最薄角膜厚度（TCT）将可疑圆锥角膜患者分为2个亚组：亚组1（TCT 520 μ m）。KMI的总体预测准确性使用受试者工作特征（ROC）曲线进行评估。结果：可疑角膜炎组（50眼）KMI平均值为0.41 ± 0.29（SD），对照组（50眼）为0.94 ± 0.29（P
PURPOSE: To evaluate the diagnostic capacity of the Ocular Response Analyzer's keratoconus match index (KMI) and keratoconus match probability (KMP) classification in keratoconussuspect eyes.SETTING: Department of Ophthalmology, University Clinics Saarland, Homburg, Germany.DESIGN: Comparative case series.METHODS: The KMI and KMP parameters in keratoconus-suspect eyes and normal eyes (control group) were compared. The quantitative keratoconus percentage index was calculated for all suspect eyes. According to the thinnest corneal thickness (TCT), keratoconus-suspect eyes were divided into 2 subgroups: subgroup 1 (TCT 520 mu m). The KMI's overall predictive accuracy was assessed using receiver operating characteristic (ROC) curves. The relationship between KMI and a series of Scheimpflug-derived keratoconus-related indices was evaluated using Spearman analysis.RESULTS: The mean KMI was 0.41 +/- 0.29 (SD) in the keratocon us-suspect group (50 eyes) and 0.94 +/- 0.29 in the control group (50 eyes) (P
