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 Home Treatment. In the initial stages, the chalazion treatment that most physicians recommend is putting a warm compress on the affected eyelid several times a day. A clean, warm wet towel is placed over the chalazion for an average of 8 minutes, three to four times a day to facilitate drainage of the oil and thus reduce the swelling.
