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 chronic noninfective inflammation of the sebaceous glands of the eyelid. They commonly affect the meibomian glands in the tarsal plate, resulting clinically as a painless, firm nodule of the eyelid. Marginal chalazia are caused by inflammation of the gland of Zeis located at the lid margin. They can affect both the upper and lower lids.
