conjunctiva

Etymology: L, conjunctivus, connecting
the mucous membrane lining the inner surfaces of the eyelids and anterior part of the sclera. The palpebral conjunctiva lines the inner surface of the eyelids and is thick, opaque, and highly vascular. The bulbar conjunctiva is loosely connected, thin, and transparent, covering the sclera of the anterior third of the eye. conjunctival, adj.

conjunctiva

The transparent membrane attached around the CORNEA, covering the white of the eye and reflected back over the inner surfaces of the eyelids.

conjunctiva

a protective covering over the front of the vertebrate eye and extending to line the eyelids, formed of a layer of MUCUS-secreting epithelium and underlying connective tissue.

Conjunctiva

The conjunctiva is a clear layer of cells that covers the eye and directly contacts the atmosphere. The conjunctiva is about five-cells thick.

conjunctiva (kn·jnk·tiˑ·v),

n the inner lining and mucous membranes of the eyelids and the front of the sclera.

conjunctiva 

A thin transparent mucous membrane lining the posterior surface of the eyelids from the eyelid margin and reflected forward onto the anterior part of the eyeball where it merges with the corneal epithelium at the limbus. It thus forms a sac, the conjunctival sac, which is open at the palpebral fissure and closed when the eyes are shut. The depths of the unextended sac are 14-16 mm superiorly and 9-11 mm inferiorly. The conjunctiva is divided into three portions: (1) The portion that lines the posterior surface of the eyelids is called the palpebral conjunctiva. It is itself composed of the marginal conjunctiva, which extends from the eyelid margin to the tarsal conjunctiva; the tarsal conjunctiva, which extends from the marginal conjunctiva to the orbital conjunctiva; and the orbital conjunctiva, which extends from the tarsal conjunctiva to the fornix. (2) That lining the eyeball is the bulbar conjunctiva. It is itself composed of the limbal conjunctiva, which is fused with the episclera at the limbus and the scleral conjunctiva, which extends from the limbal conjunctiva to the fornix. (3) The intermediate part forming the bottom of the conjunctival sac, unattached to the eyelids or the eyeball and joining the bulbar and the palpebral portion is called the fornix (conjunctival fold, cul-de-sac). See dyskeratosis; lid eversion; conjunctival gland; Krause's end bulbs; subtarsal sulcus.

Recording LG staining of the conjunctiva should be done in at least three zones: nasal, temporal and corneal, (34) but with contact lenses it can also be useful to examine the inferior and superior regions, by lifting the lids slightly.
When fluorescein is instilled it naturally collects in the 'furrows' of the normal adult bulbar conjunctiva (Figure 14), and it is only when this sign remains after more than a few minutes that it can be associated with desiccation.
40) This supports the idea that chronic irritation through the conjunctiva is the cause, (41) although it has also been suggested that dead epithelial cells may actually block the orifices.
