Treatment of Blepharitis
Begin with daily warm compresses for 5-10 minutes and eyelid hygiene using diluted baby shampoo or hypochlorous acid 0.01% cleaners, which form the foundation of blepharitis management regardless of type. 1
Understanding the Condition
Blepharitis divides into two main categories that guide treatment selection:
- Anterior blepharitis affects the eyelid skin, eyelash base, and follicles 1
- Posterior blepharitis (Meibomian Gland Dysfunction/MGD) affects the meibomian glands 1
This is a chronic condition requiring ongoing management rather than expecting complete cure. 1
First-Line Treatment Algorithm
Step 1: Conservative Management (2-4 weeks)
Warm compresses:
- Apply for 5-10 minutes once or twice daily to soften crusts and warm meibomian secretions 1, 2
- Caution: Ensure compresses are not too hot to prevent skin burns 1
- Avoid aggressive pressure in patients with advanced glaucoma (risk of increased intraocular pressure) 2
Eyelid cleansing:
- Use diluted baby shampoo or commercially available eyelid cleaners once or twice daily 1
- Hypochlorous acid 0.01% cleaners provide strong antimicrobial effects for both anterior and posterior blepharitis 1, 2
- Apply with cotton pad, ball, swab, or clean fingertip 2
- Caution: Patients with neurotrophic corneas require careful counseling to avoid corneal epithelial injury during cleansing 2
Vertical eyelid massage:
- Perform after warm compresses to express meibomian secretions, particularly beneficial for posterior blepharitis/MGD 1, 2
Artificial tears:
- Use to manage associated dry eye symptoms, especially oil or lipid-containing products 1
Step 2: Add Topical Antibiotics (if inadequate response after 2-4 weeks)
Preferred first-line topical antibiotics:
- Bacitracin or erythromycin ointment applied to eyelid margins one or more times daily for a few weeks 1
- These reduce bacterial load in anterior blepharitis 2
Important antibiotic considerations:
- Use intermittently with different medications to prevent resistant organisms 1
- Ofloxacin is NOT first-line; reserve for confirmed bacterial infection or pre-surgical prophylaxis 1
- Long-term antibiotic use may lead to resistant organisms 1
Step 3: Systemic Antibiotics (for severe or resistant cases)
For adults:
- Doxycycline is the standard regimen for severe cases 1
- Alternative: Azithromycin oral pulse regimen (1 g per week for 3 weeks) 1
- Caution: Azithromycin may cause cardiac rhythm irregularities, especially in patients with high baseline cardiovascular risk 1
For children and pregnant women:
- Erythromycin (tetracyclines contraindicated in pregnancy, nursing, and children under 8 years) 1, 2
- For children 2-17 years with atopic eyelid dermatitis: tacrolimus 0.03% ointment, with option to increase to 0.1% under ophthalmology guidance 2
Mechanism: These medications provide both antimicrobial and anti-inflammatory properties 2
Additional Treatment Options
Short-term corticosteroids (for marked inflammation)
- Consider for eyelid or ocular surface inflammation, including marginal keratitis or phlyctenules 1
- Safer options: Loteprednol etabonate and fluorometholone phosphate due to site-specific action and limited ocular penetration 1
- Use short courses only to minimize side effects 1, 2
Advanced therapies for recalcitrant cases
- Cyclosporine topical may help with posterior blepharitis and coexisting aqueous tear deficiency 1
- Topical perfluorohexyloctane prevents tear evaporation and improves dry eye symptoms 1
- In-office procedures: Vectored thermal pulsation or microblepharoexfoliation for recalcitrant cases 1
- Tea tree oil 50% for Demodex infestation in patients not improving with previous treatments 1
- Lotilaner ophthalmic solution 0.25% is the first FDA-approved therapy specifically for Demodex blepharitis, eradicating mites in 50-67% of patients 3
Adjunctive therapies
- Omega-3 fatty acid supplements show mixed evidence but may improve tear break-up time, dry eye symptoms, and meibum score 1
Critical Patient Education Points
- Daily eyelid hygiene is essential for long-term control and must continue indefinitely 1
- Symptoms often recur when treatment is discontinued 1, 2
- Complete cure is usually not possible; successful management depends on long-term treatment compliance 1
- Frequency and duration should be guided by severity and treatment response 1
