How should blepharitis be managed?

Management of Blepharitis

Blepharitis requires chronic daily treatment with warm compresses and eyelid hygiene as the foundation, with additional therapies selected based on the specific type (anterior vs. posterior) and severity. 1

Patient Education: Setting Realistic Expectations

• A cure is usually not possible, but continual daily treatment can significantly improve symptoms. 1
• Successful management depends on patient compliance with a long-term treatment regimen. 1
• Symptoms typically recur when treatment is discontinued, requiring ongoing maintenance. 1
• In children, chronic blepharokeratoconjunctivitis is often unrecognized and can lead to amblyopia, corneal opacification, and vision loss if untreated. 1

First-Line Treatment: Eyelid Hygiene and Warm Compresses

Warm Compresses

• Apply warm compresses to eyelids for several minutes to soften adherent scales and warm meibomian secretions. 1
• Use hot tap water on a clean washcloth, over-the-counter heat pack, or microwaveable bean/rice bag. 1
• Critical warning: Instruct patients to avoid compresses hot enough to burn the skin. 1
• Warm compresses are especially helpful for posterior blepharitis/meibomian gland dysfunction (MGD). 1
• Once- or twice-daily application at a convenient time is generally adequate. 1

Eyelid Cleansing

• Perform brief, gentle massage of the eyelids to remove crusting from eyelashes. 1
• Use diluted baby shampoo or commercially available eyelid cleaners on a pad, cotton ball, cotton swab, or clean fingertip. 1
• Hypochlorous acid 0.01% eye cleaners have strong antimicrobial effects for both anterior and posterior blepharitis. 1
• Eyelid cleansing is especially useful for anterior blepharitis. 1
• Schedule regularly performed eyelid cleansing daily or several times weekly to blunt chronic symptoms. 1

Meibomian Gland Expression

• Vertical eyelid massage can express meibomian secretions in MGD cases. 1
• Caution: Frequent manipulation may cause mechanically-induced irritation. 1
• Patients with advanced glaucoma should avoid aggressive lid pressure as it may increase intraocular pressure. 1
• Counsel patients with neurotrophic corneas to avoid corneal epithelial injury. 1

Adjunctive Medical Therapies

Artificial Tears

• Provide symptomatic relief for tear film instability associated with blepharitis. 1

Topical Perfluorohexyloctane

• FDA-approved in 2023 as a prescription treatment for blepharitis. 1

Antibiotics

Topical Antibiotics:

• Topical antibiotic drops or ointments (with or without corticosteroids) can be effective. 1
• Consider treating moderate to severe blepharitis with topical antibiotics and eyelid hygiene before intraocular surgery to reduce endophthalmitis risk. 1
• Warning: Long-term antibiotic treatment may result in resistant organisms. 1

Oral Antibiotics:

• Oral antibiotics (particularly doxycycline) can be used for their antibacterial and anti-inflammatory properties. 2, 3
• Azithromycin may produce cardiac arrhythmias when used orally in patients with cardiovascular problems. 1
• Evidence for oral antibiotics is very uncertain, with potential for increased adverse events. 2

Antiparasitic Medications for Demodex Blepharitis

Lotilaner Ophthalmic Solution 0.25%:

• First FDA-approved therapy specifically for Demodex blepharitis, which causes more than two-thirds of all blepharitis cases in the United States. 4
• Expert consensus (DEPTH panel) recommends lotilaner ophthalmic solution 0.25% as first-line treatment for Demodex blepharitis. 5
• Eradicates Demodex mites in one-half to two-thirds of patients with continued benefits through 1 year. 4
• The presence of collarettes (waste product of Demodex mites) on eyelash bases is pathognomonic for Demodex blepharitis. 4, 6
• For patients with >10 collarettes, no additional clinical findings are needed to prompt treatment. 5
• For patients with 0-2 or 3-10 collarettes, one additional clinical finding is needed before treatment. 5

Other Antiparasitic Options:

• Metronidazole and ivermectin are alternative antiparasitic medications. 1
• Expert consensus indicates topical and systemic ivermectin are not preferred treatments for Demodex blepharitis. 5
• No consensus was reached regarding tea tree oil for Demodex blepharitis treatment. 5

Topical Anti-Inflammatory Agents

• Corticosteroids and cyclosporine can be used as topical anti-inflammatory agents. 1
• Calcineurin inhibitors show promising results in blepharitis management. 3

In-Office Procedural Treatments

• Vectored thermal pulsation and microblepharoexfoliation are available in-office options. 1
• Blepharoexfoliation or intense pulsed light (IPL) therapy can supplement first-line treatment with lotilaner ophthalmic solution 0.25% for Demodex blepharitis. 5
• Lack of independent, randomized controlled studies demonstrating superiority of any one procedural treatment over another. 1

Treatment Algorithm by Blepharitis Type

Anterior Blepharitis (Staphylococcal/Seborrheic)

• Prioritize eyelid cleansing with hypochlorous acid 0.01% or diluted baby shampoo. 1
• Add warm compresses once or twice daily. 1
• Consider topical antibiotics if severe or not responding to hygiene measures. 1

Posterior Blepharitis/MGD

• Prioritize warm compresses to warm meibomian secretions. 1
• Perform meibomian gland expression with vertical eyelid massage. 1
• Add eyelid cleansing for additional benefit. 1
• Consider in-office thermal pulsation treatments if refractory. 1

Demodex Blepharitis

• Initiate lotilaner ophthalmic solution 0.25% as first-line treatment when collarettes are present. 5
• Supplement with blepharoexfoliation or IPL therapy if needed. 5
• Continue warm compresses and eyelid hygiene as supportive measures. 1

Red Flags Requiring Further Investigation

• Blepharitis not responding to therapy should raise suspicion for carcinoma or immune-mediated diseases, particularly with eyelash loss and/or conjunctival cicatricial changes. 1
• Early diagnosis and appropriate treatment can prevent vision loss, disfigurement, and may be lifesaving. 1
• Postoperative endophthalmitis risk is increased with moderate to severe blepharitis before intraocular surgery. 1

Common Pitfalls to Avoid

• Failing to educate patients that blepharitis is chronic and requires long-term daily treatment. 1
• Using compresses that are too hot, causing skin burns. 1
• Aggressive eyelid manipulation in patients with advanced glaucoma or neurotrophic corneas. 1
• Long-term antibiotic use without monitoring for resistant organisms. 1
• Missing Demodex blepharitis diagnosis by not examining for collarettes on eyelash bases. 4, 6
• Overlooking malignancy in refractory cases with atypical features. 1
