Drooping of the upper eyelid is known as?

• A. Ptosis
• B. Chalazion
• C. Hordeolum
• D. Ectropion

Answer: (A)

Drooping of the upper eyelid is called ptosis. It happens when the muscle that lifts the lid, the levator palpebrae superioris (often with help from Müller's muscle), is weak or not properly innervated, so the lid sits lower than normal. Ptosis can be present from birth or develop later due to nerve or muscle problems, age-related changes, or certain systemic conditions. Chalazion is a lump caused by blockage and inflammation of a meibomian gland in the eyelid. Hordeolum, or stye, is an acute infection of oil glands that causes a tender, red bump. Ectropion is when the eyelid margin turns outward, usually the lower lid, leading to irritation and tearing rather than simply a drooping of the upper lid.
