Eyelid edge swelling due to bacterial infection at the base of an eyelash

• A. Stye
• B. Sinusitis
• C. Hypotension
• D. Styes

Answer: (D)

This is describing an acute bacterial infection at the eyelash base that causes a localized swelling along the eyelid margin. That condition is a stye (also called a hordeolum). It happens when bacteria, usually Staphylococcus, invade the lash follicle or its oil gland, leading to a red, tender bump that may have a small pus-filled center. The question uses the plural form, styes, to denote the general condition or the possibility of multiple lesions, but it refers to the same problem: an eyelid edge swelling due to infection at the lash base. The other options don’t fit because they relate to different organs or systems (sinusitis is a sinus infection and is not about the eyelid; hypotension is low blood pressure) or describe the exact same condition in its singular form, which the prompt is not targeting here. In practice, treatment focuses on warmth and eyelid hygiene to promote drainage and healing.
