Which term describes a lump on the eyelid caused by blockage of a sebaceous gland?

• A. Periorbital Edema
• B. Ectopion
• C. Chalazion
• D. Esotropia

Answer: (C)

Chalazion is the lump described here. It forms when a meibomian (sebaceous) gland in the eyelid becomes blocked, causing a backup of oily secretions and a sterile inflammatory response that creates a smooth, often painless bump inside the eyelid. This condition is typically chronic and not acutely painful, which distinguishes it from a stye, which is a painful, red infection near the lash line. Other options don’t fit the description: periorbital edema is general swelling around the eye, not a discrete eyelid lump; ectropion is when the eyelid turns outward; esotropia is inward turning of the eye (a misalignment).
