Leopardenmuster in der Fluoreszenzangiographie

Abstract

The uveal effusion syndrome is a rare disease characterized by serous choroidal detachment. The pathogenesis of idiopathic uveal effusion syndrome has not yet been conclusively established. One hypothesis is an abnormality of diffusion of extravascular proteins in the choroid leading to decompensation of the pigment epithelium pumping capacity. Fluid then accumulates in the subretinal space leading to retinal detachment which results in loss of visual acuity. It typically affects males and hypermetropia is another risk factor. When looking at the fundus a circular serous detachment of the choroid and choroidal puckering is typical. The fluorescein angiography shows hyperfluorescence in the form of a leopard-spot pattern. Space-occupying lesions have to be excluded with the help of ultrasound or magnetic resonance tomography. The uveal effusion syndrome is a diagnosis by exclusion. Treatment varies because of the different hypotheses for the pathogenesis. An intraocular tamponade in combination with laser coagulation may for example be an effective treatment.
