In this paper the GREDEA system is presented. The main idea behind it is that with the help of evolutionary algorithms a grammatical description of the blood circulation of the human retina can be inferred. The system uses parametric Lindenmayer systems as description language. It can be applied on patients with diabetes who need to be monitored over long periods of time. 1 INTRODUCTION In this paper the GREDEA (Grammatical Retina Description with Evolutionary Algorithms) system is presented. The main idea behind GREDEA was to develop patientspecific monitoring programs for examining the blood circulation of the human retina. The system can be used for on patients with diabetes who need to be monitored over long periods. It is essential to check the eyesight of patients with this disease, because the deterioration of the vascular tree caused by diabetes has a direct effect on the vision quality. In recent years some systems (such as [Georgiadis 1995], [Hipwell 1997], [Zana 199...
