Conjunctiva - Wikipedia, the free encyclopedia The conjunctiva is a membrane that covers the sclera (white part of the eye) and lines the inside of the eyelids. Disorders of the conjunctiva and cornea are a common source of eye complaints. The surface of the eye is exposed to various external influences and is especially suspectible to trauma, infections, and allergic reactions. en.wikipedia.org /wiki/Conjunctiva   (241 words)

Encyclopedia - Conjunctiva Although the conjunctiva is normally a tough, resilient tissue, in cases of ocular trauma, it may be lacerated with sharp or pointed objects such as fingernails, tree branches, or the edge of a piece of paper. Within the bulbar, conjunctivae are "goblet cells" that secrete an important component of the pre-corneal tear layer, which protects and nourishes the cornea. The fornix is a loose pocket of conjunctiva between the upper eyelid and the eyeball that permits the eyeball to rotate freely. www.visionrx.com /library/enc/enc_conjuctiva.asp   (366 words)

THE MERCK MANUAL, Sec. 8, Ch. 95, Conjunctival Disorders The conjunctiva lines the back of the lid (palpebral or tarsal conjunctiva), extends into the space between the lid and the globe (forniceal conjunctiva), and spreads up over the sclera to the cornea (bulbar conjunctiva). Gross edema with ballooning of the conjunctiva often leading to prolapse of conjunctiva is known as chemosis. A pinguecula is a raised yellowish white mass on the bulbar conjunctiva, adjacent to the cornea at the 3- and/or 9-o'clock position. www.merck.com /mrkshared/mmanual/section8/chapter95/95a.jsp   (355 words)

Conjunctivitis - Wikipedia, the free encyclopedia Conjunctivitis (commonly called "pinkeye") is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), often due to infection. Viral conjunctivitis, commonly known as "pink eye", shows a fine diffuse pinkness of the conjunctiva which is easily mistaken for the 'ciliary injection' of iritis, but there are usually corroborative signs on biomicroscopy, particularly numerous lymphoid follicles on the tarsal conjunctiva, and sometimes a punctate keratitis. Scarring of the tarsal conjunctiva suggests trachoma, especially if seen in endemic areas, if the scarring is linear (von Arlt's line), or if there is also corneal vascularisation. en.wikipedia.org /wiki/Blepharoconjunctivitis   (1389 words)

Comparative Ophthalmology Notes: Chapter 7 - Conjunctiva   (Site not responding. Last check: 2007-10-13) Conjunctiva is the mucous membrane lining the eyelids and the anterior sclera, and the nictitating membrane in those species having one. The area where the palpebral conjunctiva reflects to become the bulbar conjunctiva is called the conjunctival fornix. Chemosis (edema of conjunctiva) - this may be so great that folds of edematous conjunctiva may protrude from the palpebral fissure; although this appears grotesque, the degree of chemosis is not necessarily related to the seriousness of the problem. www.vetmed.ucdavis.edu /courses/vet_eyes/conotes/con_chapter_7.html   (1954 words)

THE MERCK MANUAL, Sec. 8, Ch. 95, Conjunctival Disorders Inflammatory papillae appear on the upper tarsal conjunctiva, and corneal neovascularization begins during this stage, with invasion of the upper half of the cornea by loops of vessels from the limbus. On healing, the conjunctiva is smooth and grayish white; the extent of residual corneal opacity and vision loss varies. Usually the palpebral conjunctiva of the upper lid is involved, but the bulbar conjunctiva may be affected in some cases. www.merck.com /pubs/mmanual/section8/chapter95/95c.htm   (923 words)

eMedicine - Conjunctivitis, Allergic : Article by Parag A Majmudar, MD   (Site not responding. Last check: 2007-10-13) Since conjunctiva is a mucosal surface similar to the nasal mucosa, the same allergens that trigger allergic rhinitis may be involved in the pathogenesis of allergic conjunctivitis. Conjunctiva may show chemosis and typically a papillary reaction, which is more prominent in the inferior tarsal conjunctiva, in contrast to that seen in vernal keratoconjunctivitis. Examination of superior tarsal conjunctiva reveals presence of large cobblestone papillae, which are generally 0.3 mm or greater in diameter and, in severe cases, may cause mechanical ptosis of the upper lid. www.emedicine.com /oph/topic85.htm   (5959 words)

The portion on the surface of the eyeball is referred to as the bulbar conjunctiva, while that on the inner surfaces of the eyelids is the tarsal conjunctiva.

Conjunctivitis (Pink Eye): Definition, Symptoms, and Treatment - Kellogg Eye Center Conjunctivitis is inflammation of the conjunctiva or thin membrane covering the white of the eye and the inner surface of the eyelid. The inflamed conjunctiva will usually make the eye appear red or pink because the tiny blood vessels that are normally within the conjunctiva are now irritated and enlarged. The white of the eye (sclera) is covered by a thin, filmy membrane called the conjunctiva which produces mucus to coat and lubricate the surface of the eye. www.kellogg.umich.edu /patientcare/conditions/conjunctivitis.html   (538 words)
