Capillaroscopic study is often performed on the patients suspected of having microcirculation problems such as Raynaud\u2019s 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.<\/jats:p>","DOI":"10.1155\/2015\/974530","type":"journal-article","created":{"date-parts":[[2015,9,1]],"date-time":"2015-09-01T17:41:05Z","timestamp":1441129265000},"page":"1-17","source":"Crossref","is-referenced-by-count":151,"title":["Nailfold
