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 ...

The conjunctiva is a tissue that lines the inside of the eyelids and covers the sclera. It is composed of unkeratinized, stratified squamous epithelium with goblet cells, and stratified columnar epithelium. The conjunctiva is basically transparent, and the white colour we see is actually sclera.
If due to a chemical splash, it is often present in only the lower conjunctival sac. With some chemicals, above all with caustic alkalis such as sodium hydroxide, necrosis of the conjunctiva marked by a deceptively white eye due to vascular closure may occur, followed by sloughing off of the dead epithelium.
Both seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC) are two acute allergic conjunctival disorders. [2] SAC is the most common ocular allergy. [1] [8] Symptoms of the aforementioned ocular diseases include itching and pink to reddish eye(s). [2] These two eye conditions are mediated by mast cells.
The lacrimal caruncle is found at the medial canthus of the eye. [1] It consists of skin, hair follicles, sebaceous glands, sweat glands, accessory lacrimal tissue and other tissues that are present in the skin and accessory lacrimal glands.
Conjunctiva, 13. 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:
Chemosis is the swelling (or edema) of the conjunctiva. The term derives from the Greek words cheme and -osis, cheme meaning cockleshell due to the swollen conjunctiva resembling it, and -osis meaning condition. [1] The swelling is due to the oozing of exudate from abnormally permeable capillaries. In general, chemosis is a nonspecific sign of ...
