What term describes the drooping of the upper eyelid?

• A. Ptosis
• B. Retinal Detachment
• C. Strabismus
• D. Pinna

Answer: (A)

Drooping of the upper eyelid is called ptosis. It happens when the muscles that lift the eyelid—the levator palpebrae superioris (and sometimes the supporting Mueller’s muscle) or their nerve supply—aren’t working properly. Ptosis can be present at birth or develop later due to nerve or muscle problems, aging, trauma, or conditions like myasthenia gravis or Horner syndrome. The other terms refer to different things: retinal detachment involves the retina, strabismus is misalignment of the eyes, and the pinna is the outer ear.
