Nailfold computed videomicroscopy in morpho-functional assessment of diabetic microangiopathy.

Although careful measurement of the size of capillary loops is mandatory in the evaluation of diabetic microangiopathy, no current technique allows rapid and careful morphometric analysis of capillaroscopic findings. In an attempt to solve this problem, assembling readily available instruments, the authors have set up an original apparatus for computed videomicroscopy. The apparatus ensures detailed morphological assessment of single loops at high magnification. Each single frame stored on videocassettes can be digitalized for morphometric analysis, saved on floppy disk or printed by means of a graphic printer.
