Meibomian Gland
Dysfunction

Meibomian gland dysfunction (MGD) is a common condition, yet many people don't realize they have it. MGD happens when there's a problem with a few dozen tiny glands in the eyelids that help make the oil/lipid layer of the tears.

What Happens

These meibomian glands make an oil called meibum. Meibum, Water, and Mucous form the three layers of tear film, the fluid that keeps the eyes moist. The oil helps prevent the water layer on the Ocular surface from evaporating or drying out too quickly.

Changes to the amount or quality of the oil, or to the glands themselves, can lead to MGD. It's often the result of a combination of things. The most common type, obstructive MGD, happens when the gland openings get clogged, and less and less oil reaches the Ocular surface.

Symptoms

In its early stage, might not have any symptoms.

But as MGD progresses, less oil or poor-quality oil in the tear film, leads to burning, itchy, irritating or dry feel. It might also feel like the presence of a grain or sand or dust in the eye. An irritated, inflamed eyelid may be red.

Occasional blurring of vision happens, which could also minimise with GOOD BLINK.
