Meibomian Gland Dysfunction

Meibomian glands are oil glands that line the edge of your eyelids. These glands secrete the oil that coats the eyes, to prevent the tears from evaporating too quickly. Meibomian gland dysfunction (MGD) is a common condition that occurs when the oil glands become blocked. The blockage prevents a normal flow of oil creates a tear film that can be gritty, poor in quality, and may cause irritation.

When the meibomian glands are healthy, the oil they produce has the consistency of olive oil. When the glands are inflamed, the oils they produce become thickened, having a consistency more like that of toothpaste, leading to clogging of your meibomian glands.

MGD often does not present symptoms in the earliest stages. As the condition progresses, it can cause dry eye symptoms and/or inflammation of the eyelid if left untreated. When MGD is left untreated, and the glands are constantly blocked, oil secretion becomes stagnant to eventually atrophied. The risk of developing MGD increases with age, contact lens wear, and digital device use. Dr. Truong is seeing younger and younger patients suffering from MGD.
