Blepharitis

Blepharitis is a common and chronic inflammatory condition affecting the eyelids, particularly at the base of the eyelashes. While not serious, it can be uncomfortable and is often associated with dry eye syndrome.

Types of Blepharitis

Anterior Blepharitis

Affects the outside front of the eyelid where eyelashes attach:

Staphylococcal blepharitis:

• Caused by Staphylococcus bacteria
• Crusty, scaly debris at lash bases
• May cause lash loss or misdirected lashes

Seborrheic blepharitis:

• Associated with seborrheic dermatitis
• Greasy, waxy scales on lid margins
• Often affects eyebrows and scalp too

Posterior Blepharitis

Affects the inner eyelid (meibomian gland dysfunction/MGD):

• Meibomian glands produce abnormal or insufficient oils
• Leads to tear film instability
• Strong association with dry eye syndrome
• May be associated with rosacea

Mixed Blepharitis

• Combination of anterior and posterior types
• Very common in practice

Symptoms

• Red, swollen eyelid margins
• Itching or burning sensation
• Gritty or foreign body sensation
• Crusting at the base of eyelashes (especially upon waking)
• Flaky skin around the eyes
• Sticky eyelids in the morning
• Watery or dry eyes
• Light sensitivity
• Blurred vision that improves with blinking
• Frothy tears

Causes and Associated Conditions

Common Causes

• Bacterial overgrowth on lid margins
• Sebaceous gland dysfunction
• Demodex mites (small mites living in hair follicles)
• Allergies

Associated Conditions

• Rosacea—skin condition causing facial redness
• Seborrheic dermatitis—dandruff
• Dry eye syndrome
• Chalazion and stye (hordeolum)
• Conjunctivitis

Complications

If untreated or poorly managed:

• Stye (hordeolum)—painful infected gland
• Chalazion—blocked meibomian gland cyst
• Chronic red eye
• Corneal damage from chronic irritation (rare)
• Eyelash abnormalities (loss, misdirection)
• Worsening dry eye

How Blepharitis Is Diagnosed

Clinical Examination

• Slit-lamp examination of:
  • Eyelid margins
  • Eyelash bases
  • Meibomian gland openings
  • Tear film
  • Cornea for any damage

Assessment

• Looking for crusting, redness, telangiectasia (dilated vessels)
• Evaluating meibomian gland secretions
• Checking for Demodex (cylindrical dandruff at lash base)

Treatment

Eyelid Hygiene (Foundation of Treatment)

Daily routine:

1. Warm compresses (5-10 minutes)

   • Softens meibomian gland secretions
   • Use warm, moist washcloth or commercial eye mask
   • Reheat as needed to maintain warmth

2. Lid massage

   • After warm compress
   • Gently massage eyelids toward lash line
   • Helps express meibomian gland contents

3. Lid scrubs

   • Clean lid margins with:
     • Commercial lid wipes
     • Diluted baby shampoo on cotton swab
     • Hypochlorous acid spray
   • Clean at base of lashes
   • Do both upper and lower lids

Medications

For bacterial component:

• Erythromycin ointment applied to lid margins
• Antibiotic drops (short-term)
• Oral doxycycline—anti-inflammatory effect for MGD

For inflammation:

• Short-term steroid drops
• Loteprednol ointment on lid margins

For Demodex:

• Tea tree oil-based lid wipes
• Hypochlorous acid spray
• In-office treatments

For associated dry eye:

• Artificial tears
• Prescription dry eye medications if needed

In-Office Treatments

For meibomian gland dysfunction:

• Meibomian gland expression
• LipiFlow thermal pulsation
• Intense pulsed light (IPL)
• BlephEx (mechanical debridement)

Long-Term Management

Blepharitis is a chronic condition requiring ongoing maintenance:

Daily Maintenance

• Continue lid hygiene even when symptoms improve
• Warm compresses at least once daily
• Lid cleaning as recommended

Flare Prevention

• Identify and avoid triggers
• Maintain consistent routine
• Don't skip lid hygiene when feeling well
• Treat associated conditions (rosacea, dry eye)

Environmental Factors

• Humidifier in dry environments
• Avoid excessive eye makeup
• Replace eye makeup regularly
• Remove all makeup before bed
• Don't share eye makeup or tools

Frequently Asked Questions

Is blepharitis contagious?

No, blepharitis is not contagious. It's related to individual factors like bacteria, gland function, and skin conditions, not infection spread from person to person.

Can blepharitis be cured?

Blepharitis is typically a chronic condition that can be controlled but not permanently cured. Most people need ongoing lid hygiene to manage symptoms, though the intensity of treatment can often be reduced once symptoms improve.

How long until I see improvement?

With consistent lid hygiene, most people notice improvement within 2-4 weeks. However, maintaining the routine is essential—symptoms often return if treatment stops.

Can I wear contact lenses with blepharitis?

Contact lens wear can be challenging with blepharitis. Managing blepharitis first is important. Some people can wear contacts comfortably once blepharitis is controlled; daily disposables are often better tolerated.

Does blepharitis cause permanent damage?

Typically no. While blepharitis can be uncomfortable and chronic, it rarely causes permanent damage to vision when properly managed. Severe, untreated cases can occasionally cause corneal problems.

Should I stop wearing eye makeup?

You don't need to stop completely, but:

• Remove all makeup before bed
• Replace mascara and eyeliner every 3 months
• Avoid waterproof formulas (harder to remove)
• Avoid applying liner inside the lash line
• Consider taking breaks from makeup during flares
