A new approach in the analysis of fundus images performed in frequency domain is described. It is related to specific features of the power spectrum and refers to the notion of spectral fractal dimension as well. Preliminary calculations have been carried out for sample series of diagnosed fundus eye images. The results and proposals for further improvements of the method are discussed.
