A hordeolum is commonly known as what?

  1. A stye

  2. A chalazion

  3. A cataract

  4. An eye infection

The correct answer is: A stye

A hordeolum is commonly known as a stye. This term refers to an acute infection of the eyelid glands, typically resulting in a painful, red lump on the edge of the eyelid. It is caused by bacteria, often the same strains that cause other skin infections. Recognizing a hordeolum as a stye is important for accurate communication about the condition, facilitating the correct treatment and management. The other terms, while related to eye conditions, do not describe a hordeolum. A chalazion refers to a swelling that results from a blocked oil gland in the eyelid, which is usually not painful and develops more slowly than a hordeolum. A cataract pertains to the clouding of the lens in the eye, which primarily affects vision and is unrelated to the eyelid. An eye infection is a broader term that can include various conditions beyond a hordeolum.
