2. Definition
• • Blepharitis is a chronic inflammation of the
eyelid margins.
• • Often associated with bacterial colonization,
seborrheic dermatitis, or meibomian gland
dysfunction.
• • It may present as anterior (eyelash base) or
posterior (meibomian gland) blepharitis.

3. Etiology and Pathophysiology
• • Common causes: Staphylococcus aureus,
seborrheic dermatitis, rosacea.
• • Chronic inflammation leads to meibomian
gland dysfunction and tear film instability.
• • Results in irritation, redness, and crust
formation along lash margins.

4. Clinical Features
• • Crusted or greasy eyelashes
• • Swollen, red eyelids
• • Foreign body sensation, burning, itching
• • Fluctuating vision, especially on waking
• • Recurrent styes or chalazia

5. Diagnosis
• • Clinical diagnosis based on slit-lamp
examination.
• • Key findings: erythema, crusts, meibomian
gland blockage.
• • Swabs or cytology may rule out infection or
parasitic causes (e.g., Demodex).

6. Management
• • Lid hygiene: warm compresses, gentle
scrubbing with diluted baby shampoo.
• • Topical antibiotics (erythromycin, bacitracin)
if bacterial.
• • Artificial tears for dry eye symptoms.
• • Systemic tetracyclines for meibomian gland
dysfunction.
• • Long-term maintenance and education are
key.

7. Summary
• • Chronic blepharitis is a common, relapsing
eyelid inflammation.
• • Involves bacterial, seborrheic, or meibomian
gland components.
• • Regular eyelid hygiene is the cornerstone of
therapy.
• • Early diagnosis and patient education
prevent recurrence.
