Please familiarize yourself with these keywords before you start reading the chapter:

Aqueous humor: The fluid produced by the ciliary body that fills the anterior and posterior chambers.
Choroid: The component of the uvea that extends from the edge of the optic nerve to the pars plana.
Ciliary body: The component of the vascular tunic that produces aqueous humor and is the site of attachment for the ciliary processes and the lenticular zonules.
Cornea: The transparent, avascular structure in the anterior aspect of the eye that functions to transmit and refract light.
Iridocorneal angle: The angle formed by the cornea and the root of the iris that is the entrance to the trabecular meshwork, the site of outflow of the aqueous humor.
Iris: The anterior most portion of the vascular tunic that functions as a moveable diaphragm between the anterior and posterior chambers.
Lens: The biconvex transparent crystalline structure that is the second refracting unit of the eye.
Retina: The component of the nervous tunic of the eye containing photoreceptors for light.
Sclera: The major component of the fibrous tunic in the eye.
Optic Nerve: The nerve exiting the posterior aspect of the globe that extends to the rest of the central nervous system.
Uvea: The term for the vascular tunic of the eye.
Vitreous humor: The gel like material that fills the vitreous chamber.
