The<unk><unk>  or<unk>  cavity is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. Within the<unk><unk>  are two fluid-filled spaces: * the<unk>  chamber between the posterior surface of the cornea (i.e. the corneal endothelium) and the iris. * the posterior chamber between the iris and the front face of the vitreous. Aqueous humour fills these spaces within the<unk><unk>  and provides nutrients to the surrounding structures. Some ophthalmologists and optometrists specialize in the treatment and management of<unk><unk>  disorders and diseases.
