Diffuse Choroidal Dystrophies

Hereditary diffuse choroidal dystrophies are conditions with atrophy especially in choriocapillaris, retinal pigment epithelium and outer retinal layers. Choroideremia transmitted by X recessive inheritance and autosomal recessive Gyrate atrophy are common choroidal dystrophies. In the first decades, these two groups of diseases, whose symptoms begin with a decrease in night vision, progress with a progressive decrease in vision in the advanced decades as the pigmentary changes in the peripheral retina are also affected by the central retina. In Gyrate atrophy, progressive vision decrease and ocular complications can be stopped with dietary changes. However, the development of gene therapy and stem cell therapies for choroideremia is promising.
