Treatment of Blepharitis
First-Line Treatment: Eyelid Hygiene and Warm Compresses
Begin with daily warm compresses and eyelid hygiene for all blepharitis patients, regardless of type, and continue this regimen for 2-4 weeks before escalating therapy. 1, 2
Warm Compress Technique
- Apply warm compresses to eyelids for several minutes once or twice daily using hot tap water on a clean washcloth, over-the-counter heat packs, or microwaveable bean/rice bags 2
- Ensure compresses are not hot enough to burn the skin 1, 2
- Warm compresses are particularly effective for posterior blepharitis/meibomian gland dysfunction (MGD) as they soften crusts and warm meibomian secretions 1, 2
Eyelid Cleansing Protocol
- Gently rub the base of eyelashes using diluted baby shampoo or commercially available eyelid cleaners on a pad, cotton ball, cotton swab, or clean fingertip 2
- Hypochlorous acid 0.01% eye cleaners provide strong antimicrobial effects for both anterior and posterior blepharitis 1, 2
- For MGD specifically, perform vertical eyelid massage to express meibomian gland secretions 1, 2
- Maintain this regimen daily or several times weekly for long-term symptom control 2
Adjunctive Symptomatic Treatment
- Use artificial tears, especially those containing oil or lipid products, to manage associated dry eye symptoms 1
Second-Line Treatment: Topical Antibiotics
Add topical antibiotics if eyelid hygiene provides inadequate relief after 2-4 weeks. 1, 2
Preferred Topical Antibiotic Options
- Bacitracin or erythromycin ointment applied to eyelid margins one or more times daily or at bedtime for several weeks 1, 2
- Azithromycin in sustained-release formulation has demonstrated efficacy in reducing signs and symptoms 2
- Topical tobramycin/dexamethasone suspension may reduce symptoms 2
Critical Antibiotic Considerations
- Rotate different antibiotic classes intermittently to prevent development of resistant organisms 1, 2
- Adjust frequency and duration based on severity and treatment response 2
- Long-term antibiotic use risks creating resistant organisms 1, 2
- Topical antibiotics are effective in eradicating bacteria from the eyelid margin for anterior blepharitis 3
Third-Line Treatment: Oral Antibiotics
For MGD patients with inadequate response to eyelid hygiene and topical therapy, escalate to oral antibiotics. 2
Oral Antibiotic Regimens for Adults
- Doxycycline, minocycline, or tetracycline given daily, then tapered after clinical improvement 1, 2
- Azithromycin pulse regimen: 1 g per week for 3 weeks OR 500 mg daily for 3 days in three cycles with 7-day intervals 1, 2
- Tetracyclines and macrolides provide both antimicrobial and anti-inflammatory effects 2
Alternative Regimens for Special Populations
- Oral erythromycin or azithromycin for women of childbearing age and children under 8 years 2
- Azithromycin may cause abnormalities in heart electrical activity with potential for serious cardiac rhythm irregularities, especially in patients with high baseline cardiovascular risk 1
Specialized Treatments for Refractory Cases
Demodex Blepharitis
- Tea tree oil at 50% concentration for patients not improving with previous treatments 1, 2
- Metronidazole and ivermectin are alternative antiparasitic options 2
- Lotilaner ophthalmic solution 0.25% is the first FDA-approved therapy that eradicates Demodex mites in one-half to two-thirds of patients following short-term treatment 4
Additional Therapeutic Options
- Topical perfluorohexyloctane can prevent tear evaporation and improve dry eye symptoms 1, 2
- In-office procedures (vectored thermal pulsation, microblepharoexfoliation) for recalcitrant cases 1, 2
- Omega-3 fatty acid supplements show mixed evidence but may improve tear break-up time and meibum score 1, 2
Anti-Inflammatory Therapy
- Short course of topical corticosteroids for eyelid or ocular surface inflammation, including marginal keratitis or phlyctenules 1
- Loteprednol etabonate and fluorometholone phosphate are safer options due to their site-specific action and limited ocular penetration 1
- Cyclosporine topical may be useful in some patients with posterior blepharitis and can help manage coexisting aqueous tear deficiency 1
Critical Patient Education and Long-Term Management
Blepharitis is chronic and incurable; symptoms recur when treatment is discontinued, requiring lifelong daily eyelid hygiene for symptom control. 1, 2
- Complete cure is usually not possible, and long-term management is required 1, 2
- Treatment requires persistence and often a trial-and-error approach 2
- Daily eyelid hygiene is essential for long-term control 1, 2
Important Caveats and Special Populations
Safety Considerations
- Patients with advanced glaucoma should avoid aggressive lid pressure during massage, as this may increase intraocular pressure 2
- Patients with neurotrophic corneas should be counseled carefully to avoid corneal epithelial injury during eyelid cleansing 2
