What's in a Name, Lacrimal Caruncle

The lacrimal caruncle, or caruncula lachrymalis, is a small triangle-shaped pink bump located in the corner of the eye. Within it are sweat and oil glands. Some accessory lacrimal glands, hair follicles, and tiny pieces of fat are also contained inside this small cutaneous mass.

The purpose is to lubricate, cleanse, and moisturize the eye, along with serving as an antibacterial.

The glands in it secrete a thick whitish oily substance that is sometimes seen in the corner of a person’s eye after sleeping. On each side of the lacrimal caruncle are two tiny openings called lacrimal puncti that suction tears by vacuum each time the blinking motion of the upper eyelid has ended.
