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.
Aqueous humor is a clear, watery fluid, contained in two chambers behind the cornea, that helps to bring nutrients to the eye tissues. It is produced by the ciliary body, a ring of tissue that sits behind the iris. As it circulates, the aqueous fluid flows to the front part of the eye, where it is drained by the trabecular meshwork, a sponge-like filtering system located where the cornea and iris meet.
