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.
A transparent jelly-like fluid known as vitreous humor is found in the large posterior cavity. This substance is responsible for assisting in maintaining the appropriate intraocular pressure, retaining the shape of the eyeball, and presses the retina against the choroid.etween the iris and the cornea, the anterior chamber can be located. Alternatively, between the iris and the suspensory ligament and the lens, the posterior chamber can be located. Both chambers are fluid filled (a watery substance known as aqueous humor) and are connected at the pupil.
