title: Hereditary retinal eye diseases in childhood and youth affecting the central retina.
abstract: Hereditary dystrophies affecting the central retina represent a heterogeneous group of diseases. Mutations in different genes may be responsible for changes of the choroid (choroideremia), of the retinal pigment epithelium [RPE] (Best's disease), of the photoreceptor outer segments (Stargardt's disease) and of the bipolar and Mueller cells (x-linked retinoschisis). The correct diagnosis of hereditary retinal dystrophies is important, even though therapeutic options are limited at the moment, as every patient should get a diagnosis and be informed about the expected prognosis. Furthermore, specific gene therapy of a number of diseases such as Leber congenital amaurosis, choroideremia, Stargardt's disease, Usher Syndrome and achromatopsia is being evaluated at present. Classic examinations for patients suffering from hereditary retinal dystrophies of the central retina are funduscopy - also using red-free light - visual-field tests, electrophysiologic tests as electro-retinogram [ERG] and multifocal ERG and tests evaluating color vision. Recently, new imaging modalities have been introduced into the clinical practice. The significance of these new methods such as high-resolution spectral-domain optic coherence tomography [SD-OCT] and fundus autofluorescence will be discussed as well as "next generation sequencing" as a new method for the analysis of genetic mutations in a larger number of patients.
