著作说明
《角膜影像图谱》是眼内科医生、眼外科医生和实习生的综合参考资料，涵盖了角膜成像的各个方面，从基本地形图的解读到高级诊断的应用，并包含了1200多幅代表各种设备和技术的说明性图像和图形。
J. Bradley Randleman教授、Marcony Santhiago教授和William J. Dupps Jr教授共同指导读者，通过使用大量不同的技术和独立设备来分析角膜图像，呈现了完整的角膜成像基本方法和角膜疾病病理过程，使读者通过可视化技术理解疾病的病理进程。
无论使用哪种检测设备，无论检测结果通过何种形式表现，《角膜影像图谱》都一应俱全，旨在帮助眼科从业人员识别角膜的细微变化，评估其弱化或病理性体征。同一临床疾病的多次重复显示，同一只眼睛的大量互补图像，以提供每个病例的全面介绍。
《角膜影像图谱》提供了以下方面的信息：
角膜地形图
角膜扩张评估
角膜和屈光手术评估
与角膜疾病的临床相关性
角膜和屈光手术并发症
白内障手术评估
《角膜影像图谱》着重于图像分析，以促使眼科工作者了解所有关于角膜成像的不同技术，填补了当今可用的角膜成像资源中的一个重大空白。
