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 and Vitreous â The aqueous is located in between the cornea and the lens and is a very thin fluid. It gives the front of the eye its shape as well as nourishes the cornea and lens. The Vitreous is a thicker substance that gives the inner eye it essential shape. With age, it thins and can cause damage to the retina. Retina â The retina is the sensory tissue that lines the inner layer of the eye, and converts light rays into electrical impulses that communicate with the brain. It is made up millions of photoreceptors known as rods and cones. (For More Information, See Retina page). Structure of the eye (www.stlukeseye.com/Anatomy.asp) Vision:
