What Is Meibomian Gland Dysfunction (MGD)?

Understanding the Leading Cause of Chronic Dry Eye

Dry, irritated eyes are one of the most common complaints we hear from patients in Columbus, Georgia. While many people assume dry eye is simply a lack of tears, the truth is that most cases are caused by a condition called Meibomian Gland Dysfunction (MGD).

MGD is the leading cause of evaporative dry eye, and understanding it is the first step toward lasting relief.

What Are Meibomian Glands?

Meibomian glands are tiny oil-producing glands located along the edges of your eyelids. Their job is to release oils (meibum) into your tears. This oil layer:

  • Prevents tears from evaporating too quickly
  • Keeps the eyes comfortable and protected
  • Maintains clear, stable vision

When these glands aren’t working properly, tears evaporate too fast — even if your eyes are producing enough tears.

What Is Meibomian Gland Dysfunction?

MGD occurs when the meibomian glands become blocked or inflamed, preventing healthy oil from flowing into the tear film.

Instead of thin, clear oil, the glands may produce thick or hardened secretions — or stop working altogether.

Common Symptoms of MGD

Many patients are surprised to learn that watery eyes can actually be a sign of dry eye.

Symptoms may include:

  • Burning or stinging eyes
  • Redness or irritation
  • Gritty or sandy sensation
  • Blurry vision that comes and goes
  • Excessive tearing
  • Eyelid crusting or inflammation

If you live or work in Columbus, screen use, air conditioning, allergies, and outdoor heat can worsen symptoms.

What Causes MGD?

MGD develops for several reasons, including:

  • Aging
  • Excessive screen time
  • Hormonal changes
  • Eyelid inflammation (blepharitis)
  • Rosacea
  • Contact lens wear
  • Environmental factors

Left untreated, MGD can become a chronic condition.

Why Eye Drops Often Don’t Work

Artificial tears can provide temporary relief, but they do not fix blocked meibomian glands. This is why many patients feel stuck in a cycle of constant drops with little improvement.

Treating MGD requires addressing the root cause, not just symptoms.
