Understanding the Oil Layer and Meibomian Gland Health
This may involve using a specialized slit-lamp microscope to inspect the gland openings and possibly applying gentle pressure to the eyelid to express the contents and observe the flow.

Blocked oil glands in the eye area, medically known as meibomian gland dysfunction, is a common yet often overlooked cause of persistent dryness, irritation, and a gritty sensation. Diagnosis and Professional Evaluation Diagnosing blocked oil glands requires a thorough examination by an eye care professional, such as an optometrist or ophthalmologist.
Understanding the Oil Layer and Meibomian Gland Function
Advanced diagnostic tools, such as infrared imaging or meibography, can provide a detailed map of the gland structure, revealing any atrophy or loss of gland function. Each eyelid contains dozens of these glands, and their primary role is to secrete meibum, a complex oil that forms the outermost layer of the tear film.
