What Is Meibomian Gland Dysfunction (MGD)?

Written By Dhruvil Patel

Meibomian Gland Dysfunction (MGD) is one of the most common causes of dry eye symptoms and is widely recognised in clinical research, including the TFOS DEWS II report.

What Are Meibomian Glands?

Meibomian glands are tiny oil-producing glands located along the eyelid margins. Their role is to produce the lipid layer of the tear film, which prevents tears from evaporating too quickly.

What Happens in MGD?

In MGD:

  • Glands become blocked or inflamed

  • Oil quality reduces

  • Tear evaporation increases

This leads to symptoms such as:

  • Dryness

  • Irritation

  • Watering

  • Blurred vision

Why Is MGD So Common?

MGD is increasingly common due to modern lifestyles:

  • Increased screen time

  • Reduced blinking

  • Environmental factors

  • Age-related gland changes

Signs to Look Out For

  • Red or inflamed eyelids

  • Crusting along lashes

  • Gritty sensation

  • Fluctuating vision

Many patients in Northamptonshire experience these symptoms without realising the cause.

Tips to Support Meibomian Gland Health

• Warm compresses (daily)
• Gentle eyelid cleansing
• Regular blinking during screen use
• Staying hydrated

Why Early Management Matters

MGD is often chronic but manageable. Early support can help maintain gland function and improve long-term comfort.
