Central serous retinopathy. Central serous retinopathy (CSR), also known as central serous chorioretinopathy (CSC or CSCR), is an eye disease which causes visual impairment, often temporary, usually in one eye. When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
Central Serous retinopathy is a collection of fluid under the retina that results from a leak of fluid under the retina.As the name suggest, the collection of fluid affects central vision where it causes visual loss and distortion.he exact etiology of central serous retinopathy is highly controversial. However, there appears to be an imbalance in the amount of fluid which enters the subretinal space and the ability to remove it, resulting in a net accumulation of fluid beneath the retina.
