Keratoconus (KC) is a progressive ectatic corneal disorder. There are multiple topographic devices and their varied indices used for diagnosis, detecting progression, and deciding management. It is important to understand the repeatablility, intra- test variabililty, and comparability amongst various topographic devices. The Scheimpflug camera-based devices, such as the Pentacam (Oculus, Wetzlar, Germany), Galilei (Ziemer, Biel, Switzerland), and Sirius (Costruzione Strumenti Oftalmici, Florence, Italy) are known to assist in the detection of early keratoconus and subclinical keratoconus. This article reviews the various Scheimpflug camera-based devices in depth, addressing their different indices, diagnostic accuracy, repeatability, and agreement and identifying the strongest parameter of each device. It will guide the practicing clinician by giving practical tips for decision making in the diagnosis and management of keratoconus.
圆锥角膜（KC）是一种进行性扩张性角膜疾病。有多种地形图设备及其不同的指标用于诊断、检测病情进展和确定治疗方案。了解各种地形图设备之间的可重复性、测试内变异性和可比性很重要。基于Scheimpflug相机的设备，如Pentacam（德国韦茨拉尔Oculus公司）、Galilei（瑞士比尔Ziemer公司）和Sirius（意大利佛罗伦萨Costruzione Strumenti Oftalmici公司），已知有助于早期圆锥角膜和亚临床圆锥角膜的检测。本文深入回顾了各种基于Scheimpflug相机的设备，讨论了它们不同的指标、诊断准确性、可重复性和一致性，并确定了每种设备最强的参数。它将通过提供圆锥角膜诊断和治疗决策的实用技巧来指导临床医生。
