Blepharitis Treatment

What is blepharitis?

Blepharitis is a common inflammatory condition affecting the margin of the eyelids, that is, their edge. It can affect the roots of the eyelashes (anterior blepharitis), as well as the area behind them (posterior blepharitis).

In posterior blepharitis, the meibomian glands are often affected, causing thick or frothy secretions on the lid margin (meibomitis). These glands secrete a fatty substance that protects the tear film from evaporation. When they malfunction, the stability of the tears is disrupted; for the link to dry eye syndrome and IPL, see also the dry eye syndrome & IPL page.

Classification into anterior or posterior form guides treatment; many patients have elements of both. Examination at the check-up helps map out the dominant form.

What are the causes?

In most cases, the exact cause is not clear.

In anterior blepharitis, increased bacterial activity plays an important role.

Posterior blepharitis is often linked to dermatological conditions, such as seborrhoeic dermatitis and rosacea.

Demodex (an eyelash mite) can contribute to chronic or recurring blepharitis, with characteristic flakes at the base of the eyelashes.

Symptoms and signs

Watering — Disruption of the lipid layer of the tears leads to instability of the tear film and areas of dryness. This causes reflex overproduction of tears, without effective lubrication of the eye. For other causes of tear flow, see treatment of watery eyes.

Eyelid swelling — Blockage of the meibomian glands can lead to inflammatory reactions. The so-called "cysts" are usually localised inflammations (chalazia), which may resolve or remain as a palpable lump; details at chalazion surgery.

Eyelash loss / changes to the lid margin — Seen mainly in chronic forms of the disease and require ophthalmological assessment to rule out other causes and adjust long-term treatment.

Is it a chronic condition?

Not necessarily. Blepharitis usually has flare-ups and remissions and rarely stays in a severe form for a long period.

A hygiene routine and reassessment reduce flare-ups; after remission, maintenance is often continued a few times a week as directed.

What makes it worse?

Blepharitis is worsened by:

• Cold and wind
• Air conditioning
• Prolonged screen use
• Lack of sleep
• Contact lens wear
• Dehydration
• Coexisting skin conditions

Recognising personal triggers (screen breaks, a humidifier, adjusting contact lens habits) supports medical treatment without replacing it.

How is the diagnosis made?

Diagnosis is mainly clinical and based on examination by the ophthalmologist (slit-lamp biomicroscopy, assessment of meibomian ducts, eyelashes and, where needed, the corneal surface).

In persistent or atypical cases, further investigation is discussed according to the history; the first basis remains a detailed clinical picture as part of a check-up or a visit for a specific eyelid problem.

Treatment

Proper eyelid hygiene is the basis of treatment. Daily application is recommended, intensively at first and then on a long-term basis to control flare-ups.

The three basic steps:

• Heat — applied for around 5 minutes. Helps liquefy secretions and unblock the glands. Special heated masks give a more consistent result.
• Massage — gentle pressure on the eyelids towards the eye, to expel the fatty secretion.
• Cleansing — using special sterile wipes or solutions to clean the lid margin.

The sequence and frequency are adjusted to the severity of the inflammation; excessive rubbing or products used without guidance can worsen the condition.

Targeted treatment for demodex is carried out with tea-tree-oil preparations in sessions at the practice.

Medication

Medication is given selectively, as a supplement to hygiene:

• Oral antibiotics in resistant cases
• Topical antibiotic ointment for a limited period, following medical guidance

The type, duration and need for systemic treatment are determined individually; do not change doses or duration on your own without reassessment.

What else can help?

Artificial tears help relieve symptoms, even when there is watering, as they improve the quality of the tear film.

Preservative-free options are chosen where irritation is a concern, and combined with the dry eye / IPL plan when there is coexisting film dysfunction.

Treatment with IPL (Intense Pulsed Light)

IPL is a modern, non-invasive treatment for chronic posterior blepharitis and meibomian gland dysfunction. It acts through thermal energy that:

• Liquefies the thick secretion
• Reduces inflammation
• Limits telangiectasia (visible small blood vessels)
• Reduces microbial load and Demodex

It improves symptoms such as burning, redness and a foreign-body sensation. A course of sessions and combination with meibomian gland expression: details at dry eye & IPL.

When is IPL indicated?

It is mainly indicated when:

• There is chronic posterior blepharitis (MGD)
• There is no satisfactory response to conservative treatment
• Rosacea is also present
• There are frequent recurrences

The final decision is made after clinical assessment and a discussion of risks and benefits. For an overview of services: services; for appointments, contact.
