Nailfold capillaroscopy

Nailfold capillaroscopy is a non-invasive diagnostic technique used to visualise and assess the microcirculation in the nailfold capillaries, providing insights into vascular health. It is clinically significant for diagnosing conditions such as systemic sclerosis and other connective tissue diseases, as it can reveal characteristic capillary abnormalities. A key association is the presence of capillary dilatation and loss, which can indicate disease progression and severity.
