It is a simple, noninvasive tool for analyzing microvascular abnormalities and, as such, can be used in both adults and children. Capillaroscopy has proven to be useful in many diseases, but it is of particular value in Raynaud phenomenon and other autoimmune diseases.The test is used to analyze capillaroscopic patterns in the nailfold bed of the second to fifth fingers of each hand. A normal capillaroscopic pattern is characterized by the presence of 7 to 11 capillaries in a hairpin shape. Pathologic patterns are characterized by morphologic and structural alterations, such as ectasias, giant capillaries, pathologic hemorrhages, avascular areas, and neoangiogenesis.In this article, we review the fundamentals of capillaroscopy, with an emphasis on the technique and its indications, diagnostic value, and use as a prognostic tool for rheumatologic disorders.
