Which condition is caused by bacteria or blockage of oil glands at the eyelid edge, resulting in a painful red lump?

• A. External Eyelid Stye
• B. Blepharitis
• C. Entropion
• D. Watery Eyes

Answer: (A)

Recognize a painful red lump at the eyelid margin as a stye (hordeolum). This specific presentation happens when bacteria, usually Staphylococcus, infect a lash follicle or block an oil gland at the eyelid edge, producing a tender, inflamed lump at the rim. That combination of a localized, painful lump with eyelid edge involvement is characteristic of an external stye. Blepharitis, by contrast, is chronic inflammation of the eyelid margin that causes redness, irritation, and crusting along the lid but not a single painful lump. Entropion is a structural issue where the eyelid turns inward, causing irritation rather than a discrete lump. Watery eyes describe tearing without a lump. If the lump is indeed a stye, warm compresses can help, and seek care if there’s worsening pain, vision changes, or spreading redness.
