Uvea with 14. Iris, 15. Ciliary body. The anterior segment or anterior cavity[ 1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [ 2][ 3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea ...
The anterior chamber ( AC) is the aqueous humor -filled space inside the eye between the iris and the cornea 's innermost surface, the endothelium. [1] Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury.
The front part is also called the anterior segment of the eye. The eye is not shaped like a perfect sphere; rather it is a fused two-piece unit, composed of an anterior (front) segment and the posterior (back) segment. The anterior segment is made up of the cornea, iris and lens.
The iris ( pl.: irides or irises) is a thin, annular structure in the eye in most mammals and birds, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Along with the anterior chamber and lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. [1] [2] In humans, the refractive power of the cornea is approximately 43 dioptres. [3]
Globe (human eye) Schematic diagram of the human eye. The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit ...
Part Area Palpebral or tarsal conjunctiva Lines the eyelids Bulbar or ocular conjunctiva Covers the eyeball, over the anterior sclera: This region of the conjunctiva is tightly bound to the underlying sclera by Tenon's capsule and moves with the eyeball movements. The average thickness of the bulbar conjunctival membrane is 33 microns.
The choroid, also known as the choroideaor choroid coat, is a part of the uvea, the vascularlayer of the eye. It contains connective tissues, and lies between the retinaand the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1]The choroid provides oxygenand ...
