Blepharitis: Causes, Treatments and How to Manage It Long-Term

What Is Blepharitis?

Blepharitis is a chronic inflammatory condition of the eyelid margins — the edges of the eyelids where the lashes grow. It is one of the most common conditions seen in optometric and ophthalmic practice, affecting people of all ages, and is a leading contributor to dry eye symptoms, ocular discomfort, and reduced quality of life.

Despite being extremely prevalent, blepharitis is frequently underdiagnosed and undertreated. Many people live with persistent symptoms for years without realising that a structured eyelid hygiene routine can dramatically improve their comfort and eye health.

Types of Blepharitis

Blepharitis is broadly classified by the location and underlying cause of inflammation:

Anterior Blepharitis

Affects the front of the eyelid margin, around the base of the lashes. The two main subtypes are:

• Staphylococcal blepharitis — caused by an overgrowth of Staphylococcus aureus or S. epidermidis bacteria on the lid margin. Characterised by hard, brittle scales (collarettes) around the lash bases, lash loss, and lid margin redness. Can cause a toxic keratopathy affecting the cornea.
• Seborrhoeic blepharitis — associated with seborrhoeic dermatitis and Malassezia yeast overgrowth. Produces greasy, waxy scales on the lashes and lid margins. Often occurs alongside dandruff and facial seborrhoeic dermatitis.

Posterior Blepharitis (Meibomian Gland Dysfunction)

Affects the inner eyelid margin and the meibomian glands — the oil-secreting glands that produce the lipid layer of the tear film. Meibomian gland dysfunction (MGD) is the most common form of blepharitis and the leading cause of evaporative dry eye disease. The meibum becomes thickened and inspissated, blocking the gland orifices and causing tear film instability, ocular surface inflammation, and progressive gland atrophy if left untreated.

Mixed Blepharitis

Anterior and posterior blepharitis frequently coexist, and the distinction is not always clinically clear-cut. Most patients presenting with chronic blepharitis have elements of both.

Demodex Blepharitis

An increasingly recognised subtype caused by infestation of the eyelash follicles with Demodex folliculorum and D. brevis — microscopic mites that are a normal part of the skin microbiome but can proliferate excessively, particularly with age. The hallmark sign is cylindrical dandruff (CD) — waxy, sleeve-like deposits encircling the lash shafts. Demodex blepharitis is associated with chronic inflammation, recurrent styes (hordeola), and chalazia, and requires specific treatment targeting the mites.

Symptoms of Blepharitis

Symptoms are typically bilateral and worse in the morning:

• Red, swollen, or itchy eyelid margins
• Crusting or flaking at the base of the lashes, particularly on waking
• A gritty, burning, or foreign body sensation
• Watery or sticky eyes
• Sensitivity to light (photophobia)
• Blurred vision that improves with blinking
• Recurrent styes or chalazia
• Eyelash loss or misdirected lashes (trichiasis)
• Frothy or foamy tears at the inner corner of the eye (a sign of MGD)

The Link Between Blepharitis and Dry Eye

Blepharitis and dry eye disease are intimately connected. MGD — the most common form of posterior blepharitis — directly disrupts the lipid layer of the tear film, accelerating tear evaporation and driving evaporative dry eye. Conversely, the inflammatory mediators released in blepharitis damage the conjunctival goblet cells that produce mucin, further destabilising the tear film.

This bidirectional relationship means that treating blepharitis effectively is often the most impactful intervention for patients with co-existing dry eye disease. Lubricating drops alone will not resolve symptoms if underlying lid disease is not addressed.

Evidence-Based Treatments for Blepharitis

1. Warm Compresses

The cornerstone of MGD management. Applying a warm compress at 40–45°C for a minimum of 10 minutes softens the inspissated meibum, making it expressible and restoring lipid layer quality. Consistency is critical — once-daily warm compress therapy, maintained long-term, produces the most meaningful clinical improvement. A dedicated heat mask (reusable or microwaveable) delivers more consistent and sustained heat than a flannel, which cools rapidly.

2. Lid Massage

Performed immediately after warm compress therapy while the meibum is softened. Gentle digital pressure applied along the lid margin in the direction of the lash line expresses the liquefied meibum from the gland orifices. This should be performed on both upper and lower lids.

3. Eyelid Hygiene

Daily cleansing of the lid margins removes bacterial biofilm, debris, scales, and excess meibum — reducing the microbial load and inflammatory stimulus on the lid margin. Options include:

• Eyelid wipes — pre-moistened, individually wrapped wipes formulated for lid margin cleansing. Convenient for daily use. Optase Manuka Eyelid Wipes combine cleansing with the antimicrobial properties of manuka honey, making them particularly effective where bacterial overgrowth is a factor. Zocular Eyelid Wipes use okra-based technology to gently remove debris and biofilm.
• Eyelid gels — applied to the lid margin and lashes for a more intensive cleanse. Optase Manuka Eyelid Gel provides sustained antimicrobial and anti-inflammatory action, ideal for more symptomatic presentations.
• Blepha Duo — Blepha Duo combines a warming eye mask with cleansing wipes in a single system, streamlining the warm compress and lid hygiene steps into one convenient routine.

4. Tea Tree Oil-Based Products

For Demodex blepharitis specifically, products containing terpinen-4-ol (the active component of tea tree oil) are the treatment of choice. Terpinen-4-ol has demonstrated ovicidal and miticidal activity against Demodex in clinical studies, reducing mite burden and associated inflammation. The Eyelid Hygiene & Dry Eye Bundle includes tea tree cleansing as part of a comprehensive lid care protocol.

5. Manuka Honey

Manuka honey has well-documented antimicrobial, anti-inflammatory, and wound-healing properties. In the context of blepharitis, it reduces bacterial colonisation of the lid margin and soothes inflamed tissue. It is particularly useful in staphylococcal and seborrhoeic blepharitis, and as a maintenance treatment between flares.

6. Omega-3 Supplementation

Omega-3 fatty acids (EPA and DHA) modulate the inflammatory pathways that drive MGD and blepharitis, and improve the quality and fluidity of meibum secretions. The TFOS DEWS II report supports omega-3 supplementation as an adjunct treatment for evaporative dry eye associated with MGD.

7. Antibiotic Therapy

For moderate-to-severe anterior blepharitis with significant bacterial involvement, clinicians may prescribe:

• Topical antibiotics — chloramphenicol or fusidic acid eye drops/ointment applied to the lid margins
• Oral tetracyclines (doxycycline, lymecycline) — used for their anti-inflammatory as well as antibiotic properties in MGD; particularly effective for rosacea-associated blepharitis. Typically prescribed for 6–12 weeks.

Building an Effective Blepharitis Routine

Blepharitis is a chronic condition — it cannot be cured, but it can be effectively controlled with consistent daily management. The following routine is recommended:

• Morning: Warm compress (10 min) → lid massage → eyelid wipe or gel cleanse → lubricating drops if needed
• Evening: Repeat eyelid cleanse; apply eyelid gel if symptomatic
• Ongoing: Omega-3 supplementation daily; avoid eye make-up during flares; replace eye make-up regularly to prevent recontamination

Most patients notice meaningful improvement within 4–6 weeks of consistent treatment. Maintenance therapy should be continued indefinitely to prevent relapse.

When to Seek Professional Assessment

Consult an optometrist or ophthalmologist if:

• Symptoms persist despite 6–8 weeks of consistent lid hygiene
• You develop a painful, swollen lump on the eyelid (stye or chalazion)
• You notice changes to your vision or corneal symptoms (pain, photophobia, reduced acuity)
• Lashes are falling out or growing in the wrong direction
• You suspect Demodex infestation (cylindrical dandruff on lash shafts)
