Concretion in the palpebral conjunctiva, is called conjunctival concretion, that is a (or a cluster of) small, hard, yellowish-white calcified matter, superficially buried beneath the palpebral conjunctiva. Most of concretions in the eye form in the palpebral conjunctiva, which is a clear membrane to surround the inside of the eyelid; fewer can ...
As with all oil glands, lacrimal caruncles can become clogged, causing a pimple, whitehead, or pustule beneath the skin. Clogged oil and sweat glands in the caruncle can affect tear ducts. Treatment for dry eyes due to clogged glands includes refraining from rubbing the eyes and rinsing the eyes with clear water frequently during the day ...
Diagnosis can be further made under a slit lamp upon the observation of redundant conjunctival folds. These folds can be made more apparent by staining with fluorescein dye and by applying gentle upward pressure with a finger to the eyeball through the lower lid. In pure aqueous tear deficiency dry eye patients, fluorescein stains in the ...
The surface of the conjunctival tissue overlying a pinguecula interferes with the normal spreading of the tear film. The tear ferning test reveals abnormalities of the mucous component of the tear film, making it useful as a predictor of a person's tolerance of hydrophilic soft contact lenses. [ 7 ]
The plica semilunaris is a small fold of bulbar conjunctiva on the medial canthus of the eye.It functions during movement of the eye, to help maintain tear drainage via the lacrimal lake, and to permit greater rotation of the globe, for without the plica the conjunctiva would attach directly to the eyeball, restricting movement.

Marie, Michigan, United States A concretion is a hard and compact mass formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary ...
Bitot's spots are the buildup of keratin located superficially in the conjunctiva of human's eyes. They can be oval, triangular or irregular in shape. The spots are a sign of vitamin A deficiency and associated with drying of the cornea. In 1863, the French physician Pierre Bitot (1822–1888) first described these spots. [1]
A Gundersen flap, also known as Gundersen's flap, Gundersen's conjunctival flap, or conjunctivoplasty, and often misspelled Gunderson, is a surgical procedure for correcting corneal disease. It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva .
