In this paper we tart by considering the images obtained by means of ngiography. Stereoscopic (3D) reconstruction is first erformed by using only angiographic images. Next he combination and fusion of information from both ngiographic and laser-scan ophthalmoscopic images is)nsidered in order to overcome a number of difficules associated with the processing of the angiographic nages. From the medical point of view the 3D reconstrucon and quantification of anatomical structures in the uman retina is important for the evaluation of sev-:al pathologies.
