Which of the following statements about meibomian cysts is true?

Meibomian cysts, also known as chalazia, are indeed characterized as chronic inflammatory granulomas that occur when the meibomian glands become blocked. These glands are responsible for producing oils that help lubricate the eye. When a meibomian gland becomes blocked, it can lead to a buildup of secretions, resulting in inflammation and the formation of a cyst. This condition often develops slowly and can resolve on its own over time, but intervention may be necessary if it causes discomfort or affects vision.

Other statements such as those that describe meibomian cysts as acute infections or consistently painful are inaccurate. While they can lead to discomfort, they are not infections but rather result from chronic inflammation, and they may not always be painful or tender to the touch. Additionally, although meibomian cysts can form near the eyelid margin, they typically present as a swelling within the eyelid itself and may not always be located directly at the margin.

Therefore, the assertion that meibomian cysts are chronic inflammatory granulomas captures their nature and etiology accurately. Understanding these characteristics is essential for effective diagnosis and treatment in clinical practice.
