Systemic sclerosis (SSc) is a connective tissue disease with multi-factorial etiology and autoimmune pathogenesis. 1,2 SSc is characterized by structural and functional alterations of the microcirculation, with serious clinical implications such as Raynaud's Phenomenon (RP), digital ulcers (DU) and pulmonary arterial hypertension (PAH), 1,3-6 making morphological and functional assessment of the peripheral microvasculature a must for diagnosis, prognosis, and treatment response in SSc patients. 7-10 Nailfold videocapillaroscopy (NVC) is a safe, noninvasive, and validated method capable of detecting morphological microvascular abnormalities and differentiating between secondary RP due to SSc, primary RP and healthy subjects. 3,9,11,12 Differently from laser techniques, thermography, and other technologies, which can assess and quantify microvascular function at different skin sites, NVC allows for a morphological qualitative and semi-quantitative study of microcirculation. 3,5,9,13 The combination of these imaging techniques provides an accurate evaluation of microvascular damage in SSc and it is able to monitor response to treatment in the SSc microvasculature. 9,13-15 Therefore, it is advisable that rheumatology clinics avail themselves of a combination of morpho-structural and functional techniques, in order to create "a set" of safe and noninvasive tools for the early diagnosis and reliable quantification of SSc therapy response and disease progression. This review aims at providing updated information on the new acquisition standards for NVC and the functional techniques to
