meibomian glands — arranged in rows along the upper and lower lid margins. Every time you blink, these glands release a thin layer of oil onto the surface of your eye.

That oil layer is essential. It sits on top of your tear film and stops your tears from evaporating too quickly. Without a healthy oil layer, tears evaporate faster than they should — leaving the eye surface exposed, irritated, and uncomfortable.

When meibomian glands stop working properly, that oil supply is disrupted. This is meibomian gland dysfunction.

What goes wrong with MGD?

In most cases, the oil produced by the glands becomes thickened and waxy rather than free-flowing. The gland openings can become blocked, the oil backs up, and the glands gradually lose their ability to secrete effectively.

Over time, chronically blocked or underactive glands can begin to drop out — a process called gland atrophy. Lost gland tissue doesn't regenerate. This is why early diagnosis and treatment matters.

Several factors contribute to MGD:

• Age — gland function naturally declines over time
• Screen use — reduced blink rate leads to reduced gland stimulation
• Contact lens wear
• Certain medications including antihistamines, antidepressants, and HRT
• Skin conditions including rosacea
• Demodex mite infestation of the eyelash follicles
• Diet low in omega-3 fatty acids

What are the symptoms?

MGD symptoms are often dismissed as "just tired eyes" or assumed to be a minor irritation. They can include:

• Dryness, grittiness, or a foreign body sensation
• Burning or stinging, particularly in warm or air-conditioned environments
• Watery eyes — paradoxically, MGD can cause reflex tearing
• Blurred vision that clears temporarily with blinking
• Eyelids that feel heavy, sticky, or crusty on waking
• Discomfort with contact lens wear
• Eye fatigue, particularly with screen use

Symptoms are often worse later in the day, in dry or heated environments, and during prolonged near tasks.

How is MGD diagnosed?

A proper MGD assessment goes well beyond a standard eye examination. At our clinic, assessment includes:

Meibomian gland imaging — we use infrared meibography to visualise the glands directly and assess their structure and any atrophy present.

Gland expression — gentle pressure on the lid margins allows us to assess the quality and quantity of meibomian secretion. Healthy oil should flow freely and appear clear. Thickened, cloudy, or absent secretion indicates dysfunction.

Tear film analysis — we assess tear film stability, including how quickly the tear film breaks up between blinks.

Lid margin examination — we look for signs of inflammation, redness, capping of gland openings, and associated conditions such as blepharitis or rosacea.

Symptom scoring — validated questionnaires help us quantify your symptom burden and track your progress over time.

This thorough baseline assessment means we can recommend the right treatment for your specific presentation — and measure whether it's working.

How is MGD treated?

Treatment depends on the severity and underlying drivers of your MGD. Options range from self-care measures through to specialist in-clinic treatments.

Self-care Warm compress therapy and lid massage remain a cornerstone of MGD management. Consistent daily application softens the meibomian oil and improves gland flow. We'll show you how to do this effectively — technique matters.

Nutrition Omega-3 supplementation is supported by evidence as an adjunct to MGD treatment. We'll advise on appropriate formulations and dosage.

In-clinic treatments

For patients where self-care alone isn't sufficient — or where gland function has become significantly impaired — we offer a range of specialist treatments:

• IPL therapy — targets the inflammation driving MGD and improves gland function through photothermal stimulation
• LLLT (red and blue light) — reduces inflammation, supports gland activity, and addresses any bacterial or Demodex component
• ZEST — a deep cleaning treatment for the lid margins, particularly effective where Demodex or biofilm is contributing
• NuLids — a micro-exfoliation device for daily home use between clinic treatments
• Meibomian gland expression — performed in-clinic after warming treatments to clear blocked glands

Most patients with moderate to significant MGD benefit from a combination of in-clinic treatment and a structured home care routine. We'll build a plan that fits your presentation and your life.

Can MGD be cured?

MGD is a chronic condition — for most people it's something to be managed rather than cured. The good news is that with the right approach, symptoms can be significantly reduced, gland function can be improved, and in many cases the progression of gland atrophy can be slowed.

The earlier treatment begins, the more gland tissue there is to work with. If you've been putting up with uncomfortable eyes for a while, now is a good time to act.

Frequently asked questions

Is MGD the same as dry eye? MGD is the most common cause of dry eye disease, but not all dry eye is caused by MGD. Some patients have aqueous deficient dry eye — where the lacrimal gland doesn't produce enough watery tears — or a combination of both. A proper assessment will identify which type you have.

Can drops treat MGD? Drops can relieve symptoms temporarily but they don't address the underlying gland dysfunction. For mild MGD, drops combined with warm compresses may be sufficient. For more significant dysfunction, in-clinic treatment is usually needed to restore gland function.

How long does treatment take to work? This varies by treatment and severity. Some patients notice improvement within a few weeks of starting a treatment course. For others, the benefit builds more gradually. We'll set realistic expectations at your assessment.

Will my glands recover? Glands that are blocked or underactive can recover function with appropriate treatment. Glands that have undergone significant atrophy — where the tissue has been lost — cannot regenerate. This is one reason early intervention produces better outcomes.

Do I need a referral? No. You can book directly with us for a dry eye assessment. We're an independent specialist practice and you don't need a GP or optician referral.

Take the first step

If you recognise these symptoms, a dry eye assessment is the right starting point. We'll examine your glands, assess your tear film, explain what we find, and give you an honest picture of your options.
