Meibomian Gland Dysfunction
Meibomian glands line the eyelid margins and secrete the oil that stops tears evaporating. When they block or their secretion thickens, the tear film loses its protective layer and evaporates too quickly. This is the leading cause of dry eye.
In short
Blocked eyelid oil glands. The most common dry eye cause and the most commonly missed.
There are around thirty meibomian glands in the upper eyelid and twenty five in the lower, opening in a neat row along the lid margin just behind the lashes. Every blink squeezes a small amount of clear oil onto the tear film, and that oil is what keeps tears from evaporating within seconds.
When the glands block or the oil thickens into something closer to toothpaste, the tear film loses its lid. Tears evaporate too fast, the surface dries between blinks, and the eye responds with irritation, grittiness and often reflex watering. Left long enough, unused glands atrophy and are not recoverable, which is why early treatment matters more than the mild symptoms suggest.
The reason so many people conclude that dry eye treatment does not work is that they have been treating an evaporative problem with a volume solution. Artificial tears add water to a tear film whose problem is that it cannot hold water. The treatment for gland dysfunction is to get the glands working again.
What to expect
- Lid margin examination
- The gland openings are examined at the slit lamp for blockage, capping, thickening and inflammation.
- Expression assessment
- Gentle pressure on the lid shows what actually comes out. Clear oil is normal. Thick paste, or nothing at all, is not.
- Tear film break up time
- How long the tear film stays intact after a blink measures the practical consequence of gland function.
Our process
Evaluation45 to 60 minutes
Lid margins, gland expression, tear film stability and ocular surface all assessed together.
Warm compress and lid hygiene routinedaily, ongoing
Consistent heat softens the thickened oil so it can be expressed. Technique matters and is demonstrated rather than described.
Targeted treatment6 to 8 weeks
Escalated according to severity and response, alongside the daily routine.
Review6 to 8 weeks
Gland function and symptoms reassessed, and the plan adjusted.
What this does not do
- Improvement takes six to eight weeks of consistent daily treatment. This is the main reason people give up too early.
- Glands that have already atrophied cannot be recovered, which is the argument for treating early.
- It is a chronic condition. The routine continues once symptoms improve, because stopping brings them back.
Questions and answers
How long until I notice a difference?
Six to eight weeks of consistent daily treatment is typical. People who stop after two weeks because nothing has changed are stopping exactly when the treatment is starting to work.
Do warm compresses really help?
They do, but only if they are hot enough for long enough and done every day. Meibomian oil needs sustained heat to soften, so a briefly warmed flannel that cools in ninety seconds achieves very little. A proper heat mask held for ten minutes is a different proposition.
Is this the same as blepharitis?
They are related and often coexist. Blepharitis is inflammation of the eyelid margin, frequently involving bacteria and debris at the lash line. Gland dysfunction concerns the oil glands themselves. Both are treated with lid hygiene, often together.
Can I wear makeup?
Yes, but eyeliner applied on the inner lid margin, behind the lashes, blocks the gland openings directly. Applying outside the lash line and removing thoroughly each night makes a real difference.
