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.
Serous exudate refers to thin, clear, watery, colorless to straw-colored fluid drainage from a wound. When you sustain a skin wound, the area becomes inflamed. Small blood vessels in the area leak fluid in response to this inflammation, which seeps from the surface of the wound as serous exudate. In addition to water, serous exudate contains proteins that promote blood clotting and scab formation.
