Nail-fold capillaroscopy is a technique that aids in the early diagnosis of connective tissue diseases and in distinguishing primary from secondary Raynaud phenomenon. Its use was largely prompted by the 1973 work of Maricq and LeRoy,1 who described the different capillaroscopic patterns in connective tissue disease, including dilatation of capillary loops and focal loss of capillaries, using wide-field stereomicroscopy.
