In this paper we describe a program using the image analyzer SAMBA, which allows an automatic analysis of silver stained semithin nerve sections. The operator can interactively delimit the contour of the fascicle to be analysed by means of a digitizing tablet connected to the system which generates a mask of the region. Segmentation of the fibre images is conducted as a function of brightness threshold defined by the operator. Fibre clusters are automatically separated using morphological procedures like dilatation. Morphometric parameters such as the external and axonal diameters, myelin sheath thickness and circularity are measured. We are now testing this method on normal and pathological human superficial peroneal nerves. Preliminary results are promising and the development of adequate statistical analysis of morphometric data will provide us with a new tool for the diagnosis of peripheral neuropathies.
