![]() Optic nerve: The bundle of nerve fibers at the back of the eye that carry visual messages from the retina to the brain. Macula: The portion of the eye at the center of the retina that processes sharp, clear straight-ahead vision. Lens: The transparent structure suspended behind the iris that helps to focus light on the retina it primarily provides a fine-tuning adjustment to the primary focusing structure of the eye, which is the cornea. Iris: The colored ring of tissue behind the cornea that regulates the amount of light entering the eye by adjusting the size of the pupil. Anterior chamber: The region of the eye between the cornea and the lens that contains aqueous humor.Īqueous humor: The fluid produced in the eye.īruch's membrane: Located in the retina between the choroid and the retinal pigmented epithelium (RPE) layer provides support to the retina and functions as the 'basement' membrane of the RPE layer.Ĭiliary body: Part of the eye, above the lens, that produces the aqueous humor.Ĭhoroid: Layer of the eye behind the retina, contains blood vessels that nourish the retina.Ĭones: The photoreceptor nerve cells present in the macula and concentrated in the fovea (the very center of the macula) enable people to see fine detail and color.Ĭornea: The outer, transparent structure at the front of the eye that covers the iris, pupil and anterior chamber it is the eye's primary light-focusing structure.ĭrusen: Deposits of yellowish extra cellular waste products that accumulate within and beneath the retinal pigmented epithelium (RPE) layer.įovea: The pit or depression at the center of the macula that provides the greatest visual acuity. ![]()
