Definition
The postremal chamber of eyeball (a.k.a. the vitreous chamber) is the large posterior cavity of the eye located between the broader posterior segment region of the eyeball. It extends from the lens (anteriorly) and the retina and optic disc (posteriorly).
It occupies approximately the posterior four fifths of the eyeball and is filled with the vitreous body (containing vitreous humor), a transparent gel-like substance. The vitreous body helps maintain the spherical shape of the eyeball, supports the retina against the choroid, and help stabilize the lens.
