Chalazion (/kəˈleɪziən/) is a word that refers to a small lump or cyst that appears on the eyelid due to inflammation of a blocked gland. The word is spelled with a "ch" at the beginning, which has an aspirated pronunciation /tʃ/, indicating that there is a puff of air released when saying the sound. The "z" in the middle of the word is pronounced as /z/, and the final syllable "-ion" is pronounced as /iən/. Understanding the IPA phonetic transcription helps in correctly pronouncing and spelling this complicated medical term.
A chalazion is a common benign growth or cyst that develops within the eyelid. It typically arises from the blockage of an oil gland known as the Meibomian gland, which produces an oily substance to lubricate the eye. This blockage can occur due to the thickening and hardening of the oil, preventing it from flowing properly. As a result, the gland becomes filled with trapped oil, leading to the formation of a painless, slowly enlarging lump on the eyelid.
Typically, a chalazion appears as a firm, round, non-tender bump, which may vary in size. It usually develops on the inner surface of the upper or lower eyelid, near the eyelashes. While it is not contagious and does not cause vision impairment, it can cause mild discomfort, redness, and swelling in some cases.
Chalazions often resolve on their own within several weeks to a few months. However, warm compresses can be applied to the affected area to help soften the oil and promote drainage. In certain instances, medical intervention may be required, particularly if the chalazion becomes large, persists for a prolonged period, or starts to cause significant symptoms. Treatment options may include steroid injections, surgical drainage, or the use of antibiotic eye drops or ointments to control any associated infection.
It's important to differentiate chalazions from other eyelid conditions, such as styes or eyelid infections, which may require different treatments. Therefore, consulting with an eye care professional is recommended for an accurate diagnosis and appropriate management.
A small tumor of the border of the eyelid due to inflammation of a Meibomian gland with retention of the secretion; also written chalazium.

The word "chalazion" is derived from the Greek term "khalazō" (χαλάζω), meaning "to cause hailstones or small round objects to form or gather". This term was used metaphorically to describe the swelling or gathering of a round mass, which resembles a hailstone. The suffix "-ion" in Greek denotes a condition or state, hence "chalazion" refers to the condition of having a small round mass or swelling on the eyelid.
