Meibomian Gland Dysfunction (MGD)

Along the edge of your eyelids—right behind your eyelashes—are tiny oil-making glands called meibomian glands. Each eyelid has dozens of them. They squeeze out a clear oil (called meibum) through small openings at the lid margin. That oil spreads over your tears as a thin top layer. This oily layer slows down evaporation, keeps the tear surface smooth like glass, and helps your eyelids glide when you blink. When these glands do not make the right kind of oil, do not make enough oil, or when the openings get blocked, the tear film breaks up too fast. The eye surface dries, becomes irritated, and vision can fluctuate. That problem is called Meibomian Gland Dysfunction (MGD). It is the most common cause of evaporative dry eye.

Meibomian Gland Dysfunction (MGD) is a long-lasting eyelid condition in which the oil glands in the lids are inflamed, blocked, damaged, or not working well. Because the oil layer is poor, tears evaporate quickly. This causes dryness, burning, gritty feeling, redness, and sometimes blurred vision. MGD can be mild or severe, and it often comes and goes. It is more common with age but can affect anyone.

How MGD happens

In healthy lids, the oil is liquid and flows easily with a gentle blink. In MGD, the oil can become thick like toothpaste. The tiny openings get capped over, and bacteria and mites on the lid margin can add to the problem by making irritating by-products. Swelling and inflammation around the glands make it even harder for oil to come out. Over time, some glands can shrink or “drop out.” Less oil on the eye means faster tear evaporation, and the surface of the eye becomes rough and dry. Your brain then triggers reflex tearing—watery tears that run down your face but do not fix the underlying problem because they lack oil.

Types of Meibomian Gland Dysfunction

1) Obstructive (hyposecretory) MGD

This is the most common type. The gland openings are blocked or the oil is too thick to flow. The result is too little oil reaching the tear surface. Symptoms of dryness and irritation dominate.

2) Hypersecretory (seborrheic) MGD

Here the glands produce too much thin, poor-quality oil. The tear surface can look greasy with “foamy” tears. The oil still does not protect well, so irritation and fluctuating vision can occur.

3) Primary MGD

The dysfunction arises mainly from the glands themselves, without another eye disease causing it. Ageing changes and natural shifts in oil chemistry are common reasons.

4) Secondary MGD

Another problem triggers gland dysfunction, such as skin conditions (like rosacea), eyelid scarring diseases, or medications (for example, isotretinoin). Treating the root cause often helps the glands.

5) Non-cicatricial MGD

“Cicatricial” means scarring. In the non-scarring form, the lid margin looks fairly normal, but the oil still does not flow well. Plugs and thick oil are typical.

6) Cicatricial (scarring) MGD

Long-term inflammation or specific diseases cause scarring at the lid margin. The gland openings can be pulled inward or distorted. This can be harder to treat because the anatomy has changed.

7) Qualitative MGD (poor oil quality)

The amount of oil may be normal, but its quality is wrong—too thick, too waxy, or chemically altered—so it does not protect the tears.

8) Quantitative MGD (low oil amount)

The glands do not make enough oil, often because some glands have shrunk or stopped working. Evaporation rises even if the oil quality is okay.

9) Early vs. advanced MGD

In early disease, symptoms may be mild and glands can still recover. In advanced disease, many glands have dropped out, the lid margin is thickened, and treatment is more about control than cure.

10) Symptomatic vs. “silent” MGD

Some people have obvious symptoms; others have significant gland changes on exam but feel little discomfort. Silent MGD can still harm the tear surface over time.

Common causes and contributors

1. Ageing
   As we get older, the glands naturally produce thicker oil and fewer healthy secretions. Openings narrow, making blockages more likely.

2. Hormone changes (low androgens, menopause)
   Androgens help the glands work. With low androgen levels or menopause, oil production and quality can drop, leading to MGD.

3. Rosacea
   This common skin condition inflames facial and eyelid skin. The lid margin becomes red and irritated, and gland openings clog easily.

4. Seborrheic dermatitis (dandruff)
   Oily, flaky skin around the brows and scalp sheds onto the lids, mixing with gland oil and debris. This promotes plugging and irritation.

5. Chronic blepharitis and bacterial biofilm
   Bacteria build a sticky film along the lid margin. Their enzymes change the oil’s chemistry, making it thicker and more irritating.

6. Demodex mites
   Tiny mites living in eyelashes and follicles can trigger inflammation and add to the debris that plugs the gland openings.

7. Contact lens wear
   Long hours in contacts reduce blink quality and can disrupt the lid margin. This makes oil flow worse and speeds evaporation.

8. Heavy or improper eye makeup
   Eyeliner applied on the waterline and not removing makeup well can physically block the openings. Old mascara can carry bacteria.

9. Screen time and incomplete blinking
   When reading or using screens, we blink less and often not fully. A weak blink squeezes less oil out of the glands.

10. Dry air, air conditioning, wind, smoke
    Low humidity and moving air pull water off the eye faster. Without enough oil, the tear surface breaks up quickly.

11. Allergies and atopy
    Allergic lids are itchy; rubbing and swelling irritate the gland area. Allergic tears also contain inflammatory proteins that disturb oil.

12. Eyelid position problems (entropion, ectropion, laxity)
    When lids turn in or out or are too loose, the blink mechanics are poor. The “oil pump” action works badly, and openings can distort.

13. Scarring diseases (trachoma, ocular cicatricial pemphigoid)
    These conditions scar the lid margin, closing or twisting openings and permanently harming glands.

14. Eye surgery side effects (e.g., LASIK, cataract)
    Surgery can temporarily reduce corneal sensation and alter blink patterns. In some people, this triggers or unmasks MGD.

15. Isotretinoin (for acne)
    This drug shrinks oil glands in the skin and can temporarily suppress meibomian glands, leading to thick, limited oil.

16. Other medicines (antihistamines, anticholinergics, diuretics)
    These can dry out mucous membranes, reduce tear volume, and stress the oil layer, revealing MGD symptoms.

17. Sleep apnea mask air leak (CPAP)
    Leaking air across the lids dries the eye surface overnight, demanding more oil than the glands can supply.

18. Smoking and air pollution
    Irritants in smoke and polluted air inflame the lid margin and destabilize the tear film.

19. Low omega-3 intake / unbalanced diet
    Diet affects oil composition. Low omega-3s can make the oil thicker and less spreadable.

20. Autoimmune/inflammatory conditions (e.g., Sjögren’s, GVHD)
    Whole-body inflammation can involve the eyelids and glands, reducing healthy oil output and altering oil chemistry.

Typical symptoms

1. Dryness
   A basic “dry” feeling comes from fast tear evaporation when oil is poor. It can feel like the eye is not moist enough.

2. Burning or stinging
   Exposed nerve endings on a dry surface send burning signals. Environmental triggers (wind, AC) make it worse.

3. Grittiness or “sand in the eye”
   The rough tear surface and debris at the lid margin feel like tiny particles scratching with each blink.

4. Redness
   Inflammation of the lid margin and eye surface makes the eye look red, especially after long visual tasks.

5. Itching
   MGD often coexists with allergy or Demodex. Itch leads to rubbing, which further stresses the glands.

6. Watery eyes (paradoxical tearing)
   When the surface dries, the eye reflexively makes watery tears. They run down the cheek but do not fix the oil problem.

7. Blurry or fluctuating vision
   A smooth tear surface acts like a clear window. When it breaks up, vision blurs, often improving right after a blink and fading again.

8. Light sensitivity (photophobia)
   An irritated surface reacts strongly to light. People squint or avoid bright rooms or sunlight.

9. Stringy mucus or foamy tears
   Poor oil mixes with tear proteins and bubbles along the lid margin, forming foam or strings in the inner corners.

10. Crusting on the lashes
    Oil, skin flakes, and bacteria dry overnight and make crusts that stick the lids together in the morning.

11. Lid tenderness or pain
    Blocked glands can be sore to touch. Pressing on the lid margin may feel uncomfortable.

12. Styes or chalazia (lumps)
    When a gland opening blocks, oil backs up and forms a painful red bump (stye) or a firm lump (chalazion).

13. Contact lens intolerance
    Poor oil makes lenses feel dry and unstable. Wear time shortens and comfort drops.

14. Worse with reading or screens
    Less frequent blinking during focused tasks allows tears to break up, so symptoms rise with prolonged near work.

15. Eye fatigue
    Keeping vision clear requires frequent blinking and extra effort, so the eyes feel tired by the end of the day.

Diagnostic tests

A) Physical exam tests (doctor looks and observes)

1) External eyelid and skin inspection
The clinician looks at the lid skin, lashes, and edges without any instruments first. They note redness, flaking, clogged openings, and crusts. This simple look often tells if the lid margin is unhealthy.

2) Slit-lamp exam of the lid margin and openings
A slit-lamp is a bright microscope used in eye clinics. The doctor examines the tiny gland openings, looks for caps or plugs, checks for dilated blood vessels (telangiectasia), and sees whether oil appears when you blink.

3) Blink rate and completeness observation
You are asked to read or stare at a target while the doctor quietly watches how often and how fully you blink. Incomplete or infrequent blinks point to poor oil pumping.

4) Tear meniscus height assessment
Along the lower lid sits a small “reservoir” of tears called the tear meniscus. Too low suggests your tears are evaporating quickly or not enough tears are present.

5) Ocular surface dye staining patterns
A drop of fluorescein or lissamine green dye highlights dry spots and irritated cells. Under blue or white light at the slit-lamp, the doctor sees where tears break up and which areas are stressed.

B) Manual tests (hands-on measurements or gentle pressure)

6) Digital meibomian gland expression
The clinician gently presses the lid with a clean finger or cotton tip to see if oil comes out. Healthy oil is clear and flows easily; unhealthy oil is thick, cloudy, or does not come out at all.

7) Standardized expressibility grading (with a gland evaluator paddle)
A small, smooth tool applies consistent pressure so results are comparable. The number of glands that express and the quality of oil are scored to track severity and change over time.

8) Schirmer I test (without anesthetic)
A thin paper strip is placed at the outer lower lid for five minutes to measure tear volume. While Schirmer mainly checks watery tear production, low numbers alongside poor oil suggest a mixed problem.

9) Fluorescein tear break-up time (TBUT)
A tiny amount of dye is placed on the eye. You blink, then hold your eyes open. The doctor times how long until the first dry spot appears. Short TBUT means the tear film is unstable, often from poor oil.

10) Lid eversion and palpation
The lid is gently flipped to inspect the inner surface and the gland area. Tenderness, thickening, or scarring support the diagnosis and help separate scarring from non-scarring MGD.

C) Lab and pathological tests

11) Tear osmolarity (saltiness) measurement
A small sample of tears is tested with a handheld meter. High osmolarity means the tears are too concentrated, a sign of evaporation and surface stress often seen in MGD.

12) MMP-9 inflammatory marker test
A quick, point-of-care swab checks for an enzyme called MMP-9. A positive result shows surface inflammation, which commonly accompanies MGD-related dry eye.

13) Lid margin bacterial culture
In persistent or recurrent inflammation, a swab from the lid edge may be sent to the lab. It identifies bacteria that produce enzymes altering the oil, guiding targeted treatment if needed.

14) Lash epilation microscopy for Demodex
A few lashes are gently removed and viewed under a microscope. Seeing mites or their egg cases supports Demodex overgrowth as a contributor to MGD.

15) Conjunctival impression cytology
A soft filter paper briefly touches the white eye surface to collect surface cells. The lab looks for mucus-producing cells and inflammatory changes, showing how much the surface is affected.

D) Electrodiagnostic tests (electronic sensor–based functional tests)

16) Blink electromyography (EMG)
Small skin sensors measure the electrical activity of the blinking muscles. Weak or incomplete blink patterns can be recorded and quantified, linking poor blink mechanics to MGD.

17) Non-invasive keratography break-up time (NIKBUT)
A corneal topographer projects rings and uses a camera to track when the tear surface distorts. The system times break-up without dye, giving an objective measure of tear stability related to oil quality.

18) Meibometry (lipid measurement with a photometric sensor)
A special strip lightly touches the lid margin to collect oil, and a device measures how much lipid is present. Low readings suggest under-secretion; very high but poor-quality lipid suggests hypersecretory MGD.

E) Imaging tests (pictures of glands and tear film)

19) Non-contact infrared meibography
An infrared camera takes pictures through the lid to show the meibomian glands. The clinician can see gland “dropout,” shortening, or distortion. This is the most direct way to see gland structure.

20) Anterior segment OCT (AS-OCT) of the lid margin
OCT uses light waves to make cross-section images. It can outline gland ducts, lid margin thickness, and oil reservoirs. This helps track structural changes over time.

Core treatment

1. Melt the oil (warmth), 2) Move the oil (blinking/massage/expression), 3) Clean the edges (lid hygiene), 4) Calm inflammation (anti-inflammatory care), 5) Tackle triggers (rosacea, Demodex, makeup hygiene), 6) Protect the tear film (humidity, lubrication), and 7) Restore/Regenerate in stubborn cases (advanced procedures or biologic drops).

9. Stop smoking and avoid smoke exposure.

10. Stay hydrated; pace caffeine and alcohol.

---

When to see a doctor

• New, severe pain; sudden drop in vision; light sensitivity with redness → urgent assessment.

• Persistent burning, gritty sensation, or fluctuating blur despite home care → eye exam.

• Crusty lids, collarettes, or lash loss (possible blepharitis/Demodex) → evaluation.

• Frequent styes/chalazia → check for significant MGD.

• Contact lens intolerance or post-surgery dryness → tailored plan needed.

• You’re pregnant, breastfeeding, or have major medical conditions → medication choices must be personalized.

What to eat and what to avoid

What to eat (focus more on…):

1. Fatty fish 2–3×/week (salmon, sardines, mackerel).

2. Extra-virgin olive oil as main fat.

3. Nuts and seeds (walnuts, chia, flax) for plant omegas.

4. Colorful vegetables and berries (antioxidants).

5. Hydrating foods (cucumbers, citrus, soups).

What to limit/avoid (aim to reduce…):

FAQs

1) Is MGD the same as dry eye?
They overlap. MGD causes evaporative dry eye because the oil layer is poor. Many people have both evaporative and low tear production.

2) Can MGD be cured?
It’s usually manageable, not “once-and-done.” Think skin care for your lids—regular maintenance keeps symptoms quiet.

3) How long until I feel better?
Simple heat/massage may help in days; deeper recovery (with anti-inflammatories) can take 4–12 weeks.

4) Do warm compresses really need 10–15 minutes?
Yes—short bursts cool too quickly. Use a medical-grade mask that holds heat.

5) Are baby shampoo scrubs okay?
Better to use gentle, pH-balanced lid cleansers made for eyelids; harsh soaps can irritate.

6) Will omega-3s definitely help?
Maybe—some people notice benefit, others don’t. The science is mixed. Diet quality overall still matters.

7) Why do my symptoms worsen on computers?
You blink less when you stare. Fewer full blinks mean less fresh oil on the tear film.

8) What’s the point of IPL or thermal pulsation?
They de-clog and reset the glands, especially when home care isn’t enough or rosacea is involved.

9) Are steroid eye drops safe?
Short, supervised courses can help flares, but long use risks eye pressure rise and cataracts. Always follow your doctor’s plan.

10) I keep getting styes. Is that MGD?
Styes/chalazia are common when glands are blocked. Treating MGD reduces recurrences.

11) Can makeup cause MGD?
Makeup itself doesn’t cause it, but particles and oils can plug gland openings—clean removal and not lining the waterline help.

12) What about Demodex mites?
If present, they irritate lids. Treatments like lotilaner or careful ivermectin-based regimens can clear them.

13) Do punctal plugs help MGD?
They keep tears longer on the eye. In mixed dry eye (evaporative + low tear volume), plugs can be useful.

14) Can children or teens have MGD?
Yes—especially heavy screen users or contact lens wearers. Habits (blinks, hygiene) matter.

15) Will I need lifelong drops?
You may need maintenance (heat, hygiene, occasional meds). The goal is control with the least medicine needed.
