Abstract

A method for Determining at Least One Parameter for Diagnosis or Risk Assessment of a Disease, including AMD. The distribution of the macular pigment MP of an eye and at least one area A whose bordering line corresponds to a constant optical density MPD and/or concentration MPC of MP is determined by an analysis unit. The bordering line is subjected to a quantitative shape description. At least one parameter DP, suitable for diagnosing a disease and/or the risk of a disease is derived from the quantitative shape description of the bordering line of the areas A. The method is provided for diagnosis or risk assessment but may also be used in the context of treatment of macular pigment deficiency phenomena to select the required supplements. This method, based on the determination of the fractal dimension, is also suitable for diagnosing other diseases such as edemas, actinomycoses, atrophies or lesions.
