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. Market discount arises when a bond's value on the secondary market decreases after it has been issued, usually because of an increase in interest rates.
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.
Chalazion is a cyst in the eyelid due to a blocked oil gland. They are typically in the middle of the eyelid, red, and non painful. They tend to come on gradually over a few weeks. A chalazion may occur following a stye or from hardened oils blocking the gland. The blocked gland is usually the meibomian gland but can also be the gland of Zeis. A stye and cellulitis may appear similar. A stye; however, is usually more sudden in onset, painful, and occurs at the edge of the eyelid.
