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.
Fluid is made in the ciliary body and exists the trabecular meshwork drain. If more aqueous fluid fills the globe and can't exit fast enough, then the eye pressure will increase. This ocular pressure is transmitted back to the optic nerve head and causes mechanical strain leading to glaucomatous changes and cell death.
