[Individualization of X-flavimaculated macular dystrophy in hereditary macular dystrophies].

X-shaped macular dystrophy with flavimaculatus flecks is individualized of other heredo-macular dystrophies. This aspect was showed in two families with a retinal pigment epithelial dystrophy characterised by an X-shaped yellowish macular lesion and numerus flavimaculatus retinal flecks. Nine members were variously affected. The condition was bilateral, had a dominant inheritance, started in middle age with a slow-developing macular lesion. Visual functions were often minimally disturbed for two or three decades. Relations with others here-domacular dystrophy are discussed particularly with pattern dystrophy.
