In systemic sclerosis (SSc), microvasculopathy is an important feature, resulting in digital ulcers in 30% of patients with SSc each year.1 ,2 Assessment of microvasculopathy in SSc is of clinical interest mostly for diagnostic and therapeutic purposes.

Nailfold videocapillaroscopy has in recent years earned its place in SSc as it makes early diagnosis of SSc possible in a Raynaud's population by evaluating morphological capillary abnormalities.3–5 Within an SSc population however, there is need for a technique that can evaluate blood perfusion in a dynamic way, to evaluate evolution of disease and more importantly response to therapy. For the latter, there is no validated technique available so far. Laser speckle contrast analysis (LASCA) is a relatively new technique that measures peripheral blood perfusion (PBP) in real time over a large area, in a non-contact manner, and is less time-consuming; it is thus convenient to implement in daily practice. …
