The retina is the innermost neural layer coating the back of the eye. The most important part of the retina is the macula (8), where light is focused. The anterior chamber of the eye (9) lies between the cornea and lens. This chamber contains aqueous humor, which, like cerebrospinal fluid, contains virtually no cells and minimal protein. The largest compartment in the eye is the vitreous cavity posterior to the lens (10). Like synovial fluid, vitreous humor is rich in hyalouronic acid.
