Abstract: Two families showed a retinal pigment epithelial dystrophy characterized by an X-shaped yellowish macular lesion and numerous flavimaculatus retinal flecks. Nine members were variously affected. The condition was bilateral, had a dominant inheritance and started in middle age with a slow-developing macular lesion. Visual functions were often minimally disturbed for 2 or 3 decades. The flavimaculatus flecks which differed in number appeared only as secondary phenomena yet increased in number and size. At the onset of the disease, the ERG and EOG as well as colour vision were normal and became altered only in the course of a very slow process. Fig.1: Pedigree of families A and B Introduction: In the early sixties, Franceschetti [2] introduced the term fundus flavimaculatus in order to discriminate, from the r est of flecked-retina abnormalities (table 1), a specific aspect of the eyeground characterized by numerous, pisciform, deep, yellowish retinal flecks with fuzzy borders. His new entity assumed two major forms: the first one did not entail macular involvement, was non-evolutive and was said to be the 'pure', the other one was characterized by macular involvement [2]. Following the claim of Irvine and Wergeland in 1972 [6], in 1975, we [3, 13] claimed that Stargardt's disease and fundus flavimaculatus were one and the same, which conclusion has since been agreed l.;lpon by all the authors. Indeed, we had never found a form of fundus
