The retina converts light to electrical impulses. The chambers in front of the lens (both the anterior and posterior chambers) are filled with a clear, watery fluid called aqueous humor. The cornea and lens bend light so it passes through the vitreous gel in the back chamber of the eye and is projected onto the retina. Anterior This picture also contains other parts such optic nerve, optic disc, macula, vitreous body, retina,layer of the pigment epithelium, choroid, sclera and so on. Internal Carotid Artery Anatomical Structure. Anterior chamber and posterior chamber in the eye. You may also find posterior chamber, cornea, Schlemm’s canal, ciliary body, central retinal vein, central retinal artery as well. Blood vessels (retinal artery and vein) travel along with the optic nerve and enter and exit through the back of the eye. The iris controls the amount of light that enters the eye by opening and closing the pupil. Fluid fills most of the inside of the eye. The optic nerve carries these electrical impulses to the brain, which converts them into the visual images that you see. Anterior chamber and posterior chamber in the eye. This fluid is derived from the blood vessels in the ciliary body processes and through a circulatory recycling process flows from the posterior chamber into the anterior chamber. The eye is shaped like a round ball, with a slight bulge at the front. It can help you understand our world more detailed and specific. The rest of the retina provides side (peripheral) vision, which allows you to see shapes but not fine details.

The posterior chamber is part of the anterior segment and should not be confused with the vitreous chamber (in the posterior segment). Anteriorly by the posterior (inner) surface of the cornea. The anterior cavity is then segregated once again into two distinct chambers, the anterior chamber and the posterior chamber, by the iris. This information does not replace the advice of a doctor. Tightening (contraction) or relaxing these muscles causes the lens to change shape, allowing the eyes to focus on near or far objects (accommodation). The eye is like a camera.

The intermediate layer, divided into two parts: anterior (iris and ciliary body) and posterior (choroid) The internal layer, or the sensory part of the eye, the retina; Three chambers of fluid: Anterior chamber (between cornea and iris), Posterior chamber (between iris, zonule fibers and lens) and the Vitreous chamber (between the lens and the retina). If you have any question please do not hesitate to contact us. The slight bulge in the sclera at the front of the eye is a clear, thin, dome-shaped tissue called the, The middle layer is the choroid.
