The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera (the white of the eye).
The eyelid is made up of several layers; from superficial to deep, these are: skin, subcutaneous tissue, orbicularis oculi, orbital septum and tarsal plates, and palpebral conjunctiva.

Stratified columnar epithelium

stratified columnarinterspersed columnar cellsstratified epithelia
It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium.
Stratified columnar epithelia are found in the conjunctiva of the eye, in parts of the pharynx, anus, the uterus, and the male urethra and vas deferens.

Sclera

sclerotizedsclerotisedwhites of the eyes
The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera (the white of the eye).
Along with the vessels of the conjunctiva (which is a thin layer covering the sclera), those in the episclera render the inflamed eye bright red.

Tenon's capsule

In front it adheres to the conjunctiva, and both structures are attached to the ciliary region of the eyeball.

Supraorbital nerve

Additionally it supplies the conjunctiva of the eye, the frontal sinus and the skin from the forehead extending back to the middle of the scalp.

Goblet cell

goblet cellsglandular epithelial cellsgoblet
It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium.
They are found inside the trachea, bronchi, and larger bronchioles in the respiratory tract, small intestines, the large intestine, and conjunctiva in the upper eyelid.

Infratrochlear nerve

It then passes to the medial commissure of the eye, and supplies the skin of the upper eyelids and bridge of the nose, the conjunctiva, lacrimal sac and caruncle.

Allergy

Disorders of the conjunctiva and cornea are common sources of eye complaints, in particular because the surface of the eye is exposed to various external influences and is especially susceptible to trauma, infections, chemical irritation, allergic reactions, and dryness.

Lacrimal nerve

lacrimallacrimal branches
It enters the lacrimal gland and gives off several filaments, which supply sensory innervation to the gland and the conjunctiva.

The bulbar conjunctival microvessels are typically imaged with a high-magnification slit lamp with green filters.
The lamp facilitates an examination of the anterior segment and posterior segment of the human eye, which includes the eyelid, sclera, conjunctiva, iris, natural crystalline lens, and cornea.

Subconjunctival bleeding

Subconjunctival hemorrhage
Subconjunctival bleeding, also known as subconjunctival hemorrhage, is bleeding underneath the conjunctiva.

Pinguecula

Pinguecula
It is seen as a yellow- white deposit on the conjunctiva adjacent to the limbus (the junction between the cornea and sclera).

Contact lens

contact lensescontactscontact lense
The bulbar conjunctival microvasculature is known to dilate in response to several stimuli and external conditions, including allergens (e.g. pollen), temperature, time-of-day, contact-lens wear, and acute mild hypoxia.
One major disadvantage of PMMA lenses is that they allow no oxygen to get through to the conjunctiva and cornea, causing a number of adverse and potentially serious clinical effects.

Dry eye syndrome

dry eyekeratoconjunctivitis siccadry eyes
Disorders of the conjunctiva and cornea are common sources of eye complaints, in particular because the surface of the eye is exposed to various external influences and is especially susceptible to trauma, infections, chemical irritation, allergic reactions, and dryness.
The phrase "keratoconjunctivitis sicca" means "dryness of the cornea and conjunctiva" in Latin.

Conjunctival suffusion

Leptospirosis, an infection with Leptospira, can cause conjunctival suffusion, which is characterized by chemosis, and redness without exudates.
Conjunctival suffusion is characterized by redness of the conjunctiva that resembles conjunctivitis, but it does not involve inflammatory exudates.

Anterior ciliary arteries

The anterior ciliary arteries are seven small arteries in each eye-socket that supply the conjunctiva, sclera and the rectus muscles.

Lacrimal artery

lacrimal
Its terminal branches, escaping from the gland, are distributed to the eyelids and conjunctiva: of those supplying the eyelids, two are of considerable size and are named the lateral palpebral arteries; they run medially in the upper and lower lids respectively and anastomose with the medial palpebral arteries, forming an arterial circle in this situation.

Episcleral layer

episcleraepiscleral
Fluorescein angiography has been used to study the blood flow of the bulbar conjunctiva and to differentiate the bulbar conjunctival and episcleral microcirculation.
A vascular plexus is found between the bulbar conjunctiva and the sclera consisting of two layers of vessels, the superficial episcleral vessels and the deep episcleral vessels.

Microvessel

The conjunctiva is highly vascularised, with many microvessels easily accessible for imaging studies.
