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.
The vitreous humor is a clear gel-like substance that is composed mostly of water and gives the eye its shape and form. Vitreous Humor Function Light enters the eye through the cornea, pupil, and lens, and is then transmitted through the vitreous humor to the retina. It fills the space between the lens and the retina (80% of the volume of the eyeball) which lines the back of the eye and helps to keep the retina in place by pressing it against the choroid.
