DEFINITION of 'Market Discount'. The difference between a bond's stated redemption price and its purchase price on the secondary market, if it has been purchased at a price below par.

A chalazion is a small bump in the eyelid caused by a blockage of a tiny oil gland. A chalazion is caused by a blocked duct in one of the meibomian glands. These glands are located in the eyelid directly behind the eyelashes. They produce a thin, oily fluid that lubricates the eye.
From Wikipedia, the free encyclopedia. For the fungi genus, see Chalazion (fungus) . A chalazion (/kÉËleÉªziÉn/ ; plural chalazia /kÉËleÉªziÉ/), also known as a meibomian gland lipogranuloma, is a cyst in the eyelid that is caused by inflammation of a blocked meibomian gland, usually on the upper eyelid. Chalazia differ from styes (hordeola) in that they are subacute and usually painless nodules.
