Video nailfold capillaroscopy (NFC), considered as an extension of the widefield technique, allows a more accurate measuring and storing of capillary data and a better defining, analyzing, and quantifying of capillary abnormalities. Capillaroscopic study is often performed on the patients suspected of having microcirculation problems such as Raynaud's phenomenon as the main indication for nailfold capillaroscopy. Capillaroscopic findings based on microcirculation studies can provide useful information in the fields of pathophysiology, differential diagnosis, and monitoring therapy. Nailfold capillaroscopy provides a vital assessment in clinical practices and research; for example, its reputation in the early diagnosis of systemic sclerosis is well established and it is also used as a classification criterion in this regard. This review focuses on the manner of performing video nailfold capillaroscopy and on a common approach for measuring capillary dimensions in fingers and toes.
视频甲襞毛细血管镜检查（NFC）被视为宽视野技术的延伸，它能更准确地测量和存储毛细血管数据，更好地定义、分析和量化毛细血管异常。毛细血管镜检查通常针对疑似有微循环问题的患者进行，如雷诺现象是甲襞毛细血管镜检查的主要指征。基于微循环研究的毛细血管镜检查结果可在病理生理学、鉴别诊断和治疗监测等领域提供有用信息。甲襞毛细血管镜检查在临床实践和研究中提供了重要评估；例如，它在系统性硬化症的早期诊断中的声誉已确立，并且在这方面也用作分类标准。本综述重点关注视频甲襞毛细血管镜检查的操作方式以及测量手指和脚趾毛细血管尺寸的常用方法。
