Digital capillaroscopy in idiopathic Raynaud's disease

Nail-fold capillaroscopy is performed on 135 patients with primary Raynaud's disease. There is no significant difference between patients with long clinical story and new ones. The capillaroscopy is highly correlated with severity of vasomotor troubles. Parameters of bad prognosis are a high frequency of morphological abnormalities, venodilation, sludge phenomenon and hemorrhagies.
