[Macular dystrophies].

Macular dystrophies are a group of hereditary disorders of the macula occurring in children or young adults. The most frequent in France will be presented in detail: Best disease, Stargardt macular dystrophy, cone dystrophy, X-linked retinoschisis, pattern dystrophy, and malattia leventinese. Molecular biology studies have now mapped and identified the genes involved in these macular dystrophies. Analysis of the features of fundus examination will lead to further examinations such as fluorescein angiography, indocyanine green angiography, optical coherent tomography, electroretinography, or electrooculography, in order to confirm the diagnosis. We will also present the differential diagnosis of each of these macular dystrophies.
