Blepharitis

The eyelid margins become inflamed and crusted, causing irritation and flaking.

A way to think about it

Blepharitis is like dandruff on your eyelids. The eyelid margin gets oily, scaly, and inflamed—bacteria or oil gland dysfunction cause buildup. It's chronic, comes and goes, and requires long-term lid hygiene to manage.

What's happening in the eye

Blepharitis is inflammation of the eyelid margins where the lashes attach. Anterior blepharitis involves bacteria (Staph) and scale/crust on the lash line. Posterior blepharitis involves meibomian glands (oil glands) that become clogged and inflamed—this drives dry eye. Most patients have posterior or a mix. Inflammation is chronic and flares with poor lid hygiene, stress, or seasonal changes.

Common symptoms

  • Crusting or flaking on eyelids, worse on waking
  • Red, itchy, or irritated eyelids, gritty eye sensation
  • Foreign body feeling or mild eye pain
  • Mucoid discharge or sticky lids, especially mornings
  • Sometimes: styes or chalazia (bumps from blocked glands)

Risk factors

  • Meibomian gland dysfunction (MGD)—the most common cause
  • Staph or Demodex mites colonizing eyelids
  • Seborrheic dermatitis or rosacea (skin conditions)
  • Poor eyelid hygiene or dry environment
  • Dry eye disease often coexists
  • Stress, poor sleep, or hormonal changes

Warning signs - seek care immediately

  • Severe redness, pain, or discharge despite lid care—could signal severe infection
  • Eyelid swelling or warmth—could signal cellulitis, seek urgent care
  • Vision changes or discharge—may need antibiotic treatment or referral
  • No improvement after 4 weeks of consistent lid hygiene—may need oral antibiotics or specialist

Questions to ask your doctor

  • 1.Do I have anterior, posterior, or mixed blepharitis? Does that change treatment?
  • 2.Is my blepharitis related to rosacea or seborrheic dermatitis?
  • 3.Should I use warm compresses or IPL therapy? Which is better for me?
  • 4.Could oral doxycycline help my specific case?
  • 5.How long will I need to do eyelid hygiene—is this forever?

Blepharitis is chronic but manageable with consistent lid care. Most flare-ups resolve with hygiene and topical treatments. Complications are uncommon if treated regularly.
