BACKGROUND: Nailfold capillary microscopy is scientifically established and recognized as a diagnostic tool in clinical routine. It is, however, practiced in only a few centres. METHODS: But since a more widespread use of the method is to be expected for the near future, a consensus-meeting was held, where all German-speaking clinicians and scientists, involved in capillary microscopy, were invited. Here, the technical procedure and the most important morphological parameters were evaluated and defined according to practical clinical aspects. RESULTS AND CONCLUSION: The main task of the consensus-meeting was to develop a standard evaluation sheet, accompanied by an explanation sheet. This standard evaluation sheet focuses on semiquantitative registration of morphological parameters like density, dilation, avascular fields, perivascular edema, microbleeding, torsion, atypical capillaries and giant capillaries. This standard evaluation sheet is to be validated by determining the inter-observer-variance. Later-on an illustrated practical guideline will be published.
