  2. Sclera - Wikipedia

    en.wikipedia.org/wiki/Sclera

    The sclera, [note 1] also known as the white of the eye or, in older literature, as the tunica albuginea oculi, is the opaque, fibrous, protective outer layer of the eye containing mainly collagen and some crucial elastic fiber. [2] In the development of the embryo, the sclera is derived from the neural crest. [3]

  3. Anterior segment of eyeball - Wikipedia

    en.wikipedia.org/wiki/Anterior_segment_of_eyeball

    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 (i.e. the corneal endothelium) and the ...

  4. Conjunctiva - Wikipedia

    en.wikipedia.org/wiki/Conjunctiva

    In the anatomy of the eye, the conjunctiva (pl.: conjunctivae) is a thin mucous membrane that lines the inside of the eyelids and covers the sclera (the white of the eye). [1] It is composed of non-keratinized, stratified squamous epithelium with goblet cells , stratified columnar epithelium and stratified cuboidal epithelium (depending on the ...

  5. Trabecular meshwork - Wikipedia

    en.wikipedia.org/wiki/Trabecular_meshwork

    The trabecular meshwork is an area of tissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea).

  6. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. Other functions include maintaining the circadian rhythm, and keeping balance. Arizona Eye Model. "A" is accommodation in diopters. The eye can be considered as a living optical device.

  7. Schlemm's canal - Wikipedia

    en.wikipedia.org/wiki/Schlemm's_canal

    This causes an immune response which, in turn, clears the meshwork channel/drain of cellular build up. This allows more aqueous humour to flow into Schlemm's canal from the anterior cavity, reducing the intraocular pressure and therefore lowering the risk of glaucoma, or further damage to the optic nerve, due to overpressure in the eye.

  8. Scleral Ring - Wikipedia

    en.wikipedia.org/wiki/Scleral_ring

    The scleral ring or sclerotic ring is a hardened ring of plates, often derived from bone, that is found in the eyes of many animals in several groups of vertebrates. Some species of mammals, amphibians, and crocodilians lack scleral rings. [1] The ring is in the fibrous outer layer of the eye, called the sclera.

  9. Uvea - Wikipedia

    en.wikipedia.org/wiki/Uvea

    The uvea (/ ˈ j uː v i ə /; [1] derived from Latin: uva meaning "grape"), also called the uveal layer, uveal coat, uveal tract, vascular tunic or vascular layer, is the pigmented middle layer of the three concentric layers that make up an eye, precisely between the inner retina and the outer fibrous layer composed of the sclera and cornea.
