Show moreCentral serous chorioretinopathy (CSC) is a multifactorial disease of the retina and the choroid in the human eye. The disease is characterized by a serous detachment of the neurosensory retina in the central macula, which causes visual complaints including blurred vision, a central relative scotoma, metamorphopsia, and alterations in color and contrast vision. Multimodal imaging techniques have revealed that abnormally thickened, leaking choroidal blood vessels cause an excessive fluid outflow into the interstitial space, which presumably causes the characteristic thickened choroid. This thesis addresses the clinical spectrum of CSC including the acute CSC, the chronic CSC and the severe chronic CSC. Here we suggest a strict but practical classification of CSC phenotypes based on findings on multimodal imaging techniques. We also report on the outcome of treatment, especially photodynamic therapy (PDT), in all phenotypes of CSC and provide recommendation regarding disease management and therapy. Furthermore, in this thesis we assess the roll of genetic variations among different phenotypes of CSC for a better understanding of the pathogenesis of the disease. Despite the genetic associations found in CSC phenotypes, we conclude that the so far known genetic variations do not explain the different clinical disease presentation of CSC phenotypes. Show less
