All about blepharitis
Blepharitis is a common condition in which the edges of the eyelids become inflamed. It can cause persistent irritation, redness, crusting and dry, uncomfortable eyes. Blepharitis is usually a chronic condition, meaning that while it can be effectively controlled, it may tend to recur and often requires ongoing eyelid care.
What are the different types?
Blepharitis is broadly divided into two types. Anterior blepharitis affects the skin, eyelashes and eyelash follicles at the front edge of the eyelid. It may be associated with bacteria, dandruff/seborrhoeic dermatitis or skin conditions such as rosacea. Some patients also have Demodex mites around the eyelashes, which can contribute to inflammation.
Posterior blepharitis affects the meibomian glands, the tiny oil-producing glands within the eyelids. When these glands become blocked or their oil becomes abnormal, the tears can evaporate too quickly, contributing to dry eye. This is commonly referred to as meibomian gland dysfunction (MGD).
Many people have a combination of anterior and posterior blepharitis.
What symptoms can it cause?
Symptoms vary from person to person and may include:
• Red, swollen or irritated eyelids
• Itchy, burning or gritty eyes
• Crusting or flakes around the eyelashes, particularly in the morning
• Watery or dry eyes
• Sensitivity to light
• Blurred or fluctuating vision
• Eyelids sticking together on waking
• Contact lens intolerance
• Recurrent styes or chalazia
Blepharitis can also aggravate existing dry-eye symptoms.
How is blepharitis treated?
Treatment depends on the type and severity of blepharitis and whether there is associated dry eye or MGD. Often, a combination of treatments is required.
1. Conservative treatment
The foundation of treatment is regular eyelid hygiene. This may include:
• Warm compresses to soften oils and loosen crusting
• Gentle massage of the eyelids to encourage meibomian gland function
• Cleaning the eyelid margins and eyelashes
• Artificial tears to improve comfort and reduce dry-eye symptoms
Consistency is important. Even when symptoms improve, continuing an appropriate eyelid-care routine can help reduce recurrence.
2. Medical treatment
Depending on the underlying cause, your eye specialist may recommend:
• Antibiotic ointments or drops where bacterial involvement is significant
• Anti-inflammatory treatment, including carefully supervised steroid treatment for selected patients
• Oral antibiotics, such as doxycycline, in some patients with significant MGD or associated rosacea
• Treatments directed at Demodex, where appropriate
• Lubricating eye drops for associated dry eye
These treatments are selected according to the individual patient's findings and should be used under professional guidance.
3. In-office treatments – including ZEST
At Grosvenor Eye Clinic, we offer in-office treatments for for patients whose blepharitis persists despite routine home care. ZEST (Zocular Eyelid System Treatment) is a professional eyelid-cleaning and debridement procedure that I now offer. It uses a specialised okra-based gel and applicator system to gently cleanse the eyelid margins and remove accumulated debris, oils and biofilm, including debris associated with Demodex.
The procedure is designed to thoroughly clean areas that can be difficult to treat with routine home eyelid hygiene. It is particularly useful for patients with persistent eyelid debris, blepharitis, MGD or associated dry eye symptoms. ZEST is generally quick and non-invasive, and is normally combined with an ongoing home-care programme rather than replacing it.
Clinical evidence for in-office procedures such as eyelid debridement is developing, and ZEST should be regarded as one component of a personalised blepharitis treatment plan, rather than a permanent cure.
Is surgery for blepharitis ever required?
Most people with blepharitis do not require surgery. However, if long-standing eyelid disease has caused structural problems — such as significant eyelid malposition, scarring, or recurrent chalazia — a surgical procedure may occasionally be appropriate. The underlying blepharitis and eyelid inflammation still need to be managed.
The key message
Blepharitis is common, treatable and manageable, but it often requires long-term care rather than a one-off cure. If your eyes are persistently sore, gritty, watery, dry or crusty, an assessment can determine whether anterior blepharitis, MGD, Demodex or another condition is contributing to your symptoms.
If conventional eyelid hygiene is not providing sufficient relief, ask about ZEST® and whether an in-office eyelid treatment could form part of your personalised treatment plan.
