Meibomian Gland Dysfunction in Korea: Diagnosis and Treatment

Introduction

Meibomian gland dysfunction (MGD) is one of the most common causes of dry eye syndrome. It occurs when the small oil-producing glands located inside the eyelids do not function properly, causing unstable tears, increased evaporation, and eye discomfort.

The meibomian glands play an essential role in maintaining a healthy tear film. When these glands become blocked or produce poor-quality oil, patients may experience dryness, irritation, blurred vision, and sensitivity to light.

With increasing screen use, contact lens wear, and lifestyle changes, MGD has become a growing concern among patients seeking advanced eye care. South Korea offers modern ophthalmology services with advanced diagnostic technology and specialized dry eye treatments for both local and international patients.

This guide explains meibomian gland dysfunction in Korea, including causes, symptoms, diagnosis methods, treatment options, costs, prevention strategies, and what patients should know before visiting an eye clinic.

What Is Meibomian Gland Dysfunction?

Understanding the meibomian glands

The meibomian glands are tiny oil-producing glands located along the edges of the upper and lower eyelids.

Their main function is to produce meibum, an oily substance that:

  • Prevents tears from evaporating too quickly
  • Maintains tear film stability
  • Protects the eye surface
  • Improves visual clarity

When the glands become blocked or produce abnormal oil, the tear film becomes unstable, leading to dry eye symptoms.

Types of Meibomian Gland Dysfunction

MGD is generally classified into two main types:

Obstructive MGD

This occurs when the gland openings become blocked.

Possible causes include:

  • Thickened oil secretions
  • Eyelid inflammation
  • Age-related gland changes
Low secretion MGD

This occurs when the glands produce insufficient oil.

Possible causes include:

  • Aging
  • Chronic inflammation
  • Gland damage

Many patients experience a combination of both conditions.

Causes of Meibomian Gland Dysfunction in Korea

Excessive screen use

Long hours using computers and smartphones can contribute to MGD.

When concentrating on screens, people often blink less frequently, which can reduce natural oil distribution across the eye surface.

Common risk situations include:

  • Office computer work
  • Smartphone use
  • Online learning
  • Gaming
Aging

Meibomian gland function can decrease naturally with age.

Older adults may experience:

  • Reduced oil production
  • Increased tear evaporation
  • Greater dry eye symptoms
Contact lens use

Long-term contact lens wear may increase the risk of dry eye symptoms and meibomian gland problems.

Possible effects include:

  • Reduced comfort
  • Increased dryness
  • Eye irritation
Eyelid inflammation

Conditions such as blepharitis can affect meibomian gland function.

Symptoms may include:

  • Eyelid redness
  • Crusting around eyelashes
  • Irritation
Environmental factors

Environmental conditions may worsen MGD symptoms.

Common triggers include:

  • Dry indoor air
  • Air conditioning
  • Pollution
  • Seasonal weather changes

Symptoms of Meibomian Gland Dysfunction

Dryness and irritation

Common symptoms include:

  • Burning sensation
  • Scratchy feeling
  • Foreign body sensation
  • Eye discomfort

Many patients describe their eyes as feeling tired or dry throughout the day.

Fluctuating vision

Because the oil layer affects tear stability, MGD can cause:

  • Temporary blurry vision
  • Vision that improves after blinking
  • Difficulty maintaining focus
Eye redness

Blocked or inflamed glands may contribute to:

  • Eyelid redness
  • Eye surface irritation
  • Discomfort around the eyelids
Excessive tearing

Although MGD causes dryness, some patients experience watery eyes.

This occurs because the irritated eye surface triggers reflex tearing.

Sensitivity to light

Some patients develop increased sensitivity to:

  • Bright lights
  • Screens
  • Outdoor environments

Diagnosis of Meibomian Gland Dysfunction in Korea

Comprehensive eye examination

Korean ophthalmology clinics use advanced diagnostic methods to evaluate MGD.

Assessment may include:

  • Tear film analysis
  • Eyelid examination
  • Meibomian gland imaging
  • Tear breakup time testing
  • Eye surface evaluation
Meibomian gland imaging

Special imaging technology allows doctors to evaluate:

  • Gland structure
  • Gland loss
  • Blockage patterns
  • Overall gland health

This helps create a personalized treatment plan.

Tear film evaluation

Doctors assess tear quality by examining:

  • Tear stability
  • Tear production
  • Eye surface condition

This helps determine whether symptoms are caused by MGD, other dry eye types, or both.

Meibomian Gland Dysfunction Treatment Options in Korea

Warm Compress Therapy

How warm compresses help

Warm compress therapy is one of the most common treatments for MGD.

Heat helps:

  • Soften blocked oil secretions
  • Improve gland drainage
  • Support healthier oil production

Patients may be advised to perform regular eyelid warming routines.

Eyelid Hygiene Treatment

Cleaning the eyelid margins

Proper eyelid hygiene can help reduce buildup around gland openings.

Treatment may include:

  • Eyelid cleaning
  • Removal of debris
  • Management of eyelid inflammation

Regular care can improve gland function.

Meibomian Gland Expression

Removing blocked secretions

During gland expression, doctors apply controlled pressure to help remove thickened oil from blocked glands.

Potential benefits include:

  • Improved gland drainage
  • Better tear stability
  • Reduced discomfort

Thermal Pulsation Therapy

Advanced gland treatment

Thermal pulsation devices combine heat and gentle pressure to treat blocked meibomian glands.

Potential benefits include:

  • Improved oil flow
  • Reduced gland obstruction
  • Better tear quality

This treatment may be recommended for patients with moderate to severe MGD.

Intense Pulsed Light (IPL) Therapy

IPL for MGD

IPL therapy uses controlled light energy around the eye area to help manage certain types of dry eye related to inflammation.

Potential benefits include:

  • Reduced eyelid inflammation
  • Improved gland function
  • Better tear stability

The number of treatment sessions depends on symptom severity.

Prescription Eye Drops

Doctors may prescribe medications to manage associated inflammation or dry eye symptoms.

Options may include:

  • Anti-inflammatory eye drops
  • Lubricating drops
  • Other customized treatments

Treatment depends on the underlying cause.

MGD Treatment Before LASIK, SMILE Pro, or Cataract Surgery

Why MGD evaluation matters

Patients considering vision correction procedures should have their tear quality assessed before surgery.

Untreated MGD may affect:

  • Postoperative comfort
  • Vision quality
  • Recovery experience
Preparing the eye surface before surgery

Doctors may recommend:

  • Dry eye treatment
  • Eyelid therapy
  • Tear film improvement programs

A healthy ocular surface supports better surgical outcomes.
