What is a chalazion?

  1. A blocked tear duct

  2. A small lump resulting from inflammation

  3. Inward turning of the eyes

  4. A vision impairment condition

The correct answer is: A small lump resulting from inflammation

A chalazion is indeed characterized as a small lump resulting from inflammation, specifically of a meibomian gland in the eyelid. This gland becomes blocked, leading to the accumulation of oil and causing a localized inflammatory response. Over time, this can lead to the formation of a painless lump on the eyelid that may vary in size. Understanding the condition helps in the management and potential treatment options, which generally include warm compresses to help with drainage and, in some cases, surgical intervention if it does not resolve on its own. This definition clarifies that a chalazion is not related to tear duct issues, eye misalignment, or direct vision impairment, which distinguishes it from the other options presented.
