It is not necessary for 100% of the meibomian glands to function for adequate oils to be secreted into the tear film. Many asymptomatic patients have far fewer than 100% of the glands producing oils at any given time.

If the gland is empty of meibomian oils, it collapses in on itself. In fact even when the gland is full only a very thin film of oils may actually separate the cells lining the walls of the meibomian gland. Meibomian oils are not squirted onto the surface of the eye.

Dry eye (in the aqueous deficiency sense): Many people who have dry eye symptoms are treated as though the cause is aqueous deficiency, e.g. with artificial tear supplementation and punctal plugs, when in fact their primary problem is meibomian gland dysfunction.

A TBUT should show whether the oil layer of the tear film is adequate or not. Meibomian gland dysfunction is quite common and unfortunately it often goes undiagnosed. Even when diagnosed is often not treated or is not treated effectively until it has become chronic or severe. MGD may be inflammatory (often as a result of blepharitis) or atrophic.

Your oil glands have gone on strike! The meibomian glands are located in the eyelids. Secretions from these glands comprise the lipid (oily) layer of the tear film which is so crucial in preventing rapid evaporation of the tears.

Meibomian glands are located on the upper and lower eyelids. Meibomian gland dysfunction (MGD) occurs when the oil glands in the eye become inflamed and blocked or clogged. A chalazion (plural = chalazia) is like a bubble of fluid that forms under the eyelid if the eye’s normal secretions cannot be dispersed and become trapped in one pocket of tissue.

Symptoms of Meibomian Gland Dysfunction. The symptoms of meibomian gland disease include burning that is worst on waking (by contrast, if you have aqueous deficient eyes, burning worsens as the day goes on). Increased tear evaporation leads to dry eyes, and MGD and dry eye syndrome go hand in hand.

The meibomian glands live in the upper and lower eyelids. There are approximately 15 - 20 glands per lid. The gland openings lie on the edge of the eyelid just inside the eyelash line. The body of the gland is inside the tarsal plate, which is a very thin piece of cartilage that gives the eyelid its defined shape. When your doctor everts your lid (flips it inside out) he is flipping over the tarsal plate.

As regards meibomian gland self-expression, there are several problems with this activity. First, not all meibomian gland problems are due to blockage of the orifices. If the glands are simply under-producing oils (a common problem in peri-menopausal women) pushing on them won't do anything.

Blepharitis: Blepharitis is related because chronic blepharitis will cause chronic meibomian gland dysfunction, which in turn will cause dry eye symptoms. But blepharitis should not be confused with meibomian gland dysfunction.
