What is Demodex blepharitis and how is it treated?

Demodex blepharitis is an eyelid condition caused by an overpopulation of Demodex mites in the eyelash follicles. At ProVision Eye Associates in Blue Bell, PA, we treat it with ZEST (Zocular Eyelid System Treatment), NuLids mechanical lid hygiene, and Xdemvy (lotilaner 0.25%) — the first FDA-approved prescription treatment for Demodex blepharitis.

What are scleral contact lenses and who needs them?

Scleral lenses are large-diameter gas-permeable contact lenses that vault over the cornea and rest on the sclera. They are ideal for patients with keratoconus, irregular corneas, severe dry eye, or those who have failed conventional contact lenses. Dr. Kyle Capel at ProVision Eye Associates specializes in scleral lens fittings.

What is a binocular vision exam?

A binocular vision exam evaluates how well both eyes work together as a team. It tests for conditions like convergence insufficiency, accommodative dysfunction, and eye tracking problems that can cause headaches, double vision, and reading difficulties. ProVision Eye Associates in Blue Bell, PA offers comprehensive binocular vision evaluations.

What is IPL Optilight therapy for dry eye?

IPL Optilight (Lumenis) is an FDA-approved intense pulsed light therapy that targets the root cause of evaporative dry eye — meibomian gland dysfunction and eyelid inflammation. At ProVision Eye Associates in Blue Bell, PA, we use IPL Optilight to reduce inflammation, improve meibomian gland function, and provide lasting dry eye relief. Most patients see significant improvement after a series of 4 treatments.

What is Forma-I InMode radiofrequency treatment for dry eye?

Forma-I is a radiofrequency (RF) treatment by InMode that delivers controlled heat to the meibomian glands and periorbital tissue, liquefying blocked meibum and stimulating collagen production. At ProVision Eye Associates, we combine Forma-I with IPL and meibomian gland expression for a comprehensive dry eye treatment protocol.

What is Celluma LLLT photobiomodulation for dry eye?

Celluma LLLT (Low Level Light Therapy) uses specific wavelengths of light to reduce inflammation, stimulate cellular repair, and improve meibomian gland function. It is a painless, non-invasive treatment that complements IPL and RF therapies. ProVision Eye Associates in Blue Bell, PA offers Celluma LLLT as part of our advanced dry eye treatment protocol.

June 25, 2024·8 min read·By ProVision Eye Associates

Demodex are microscopic mites that live in eyelash follicles. When they overpopulate, they cause chronic eyelid inflammation, itching, and dry eye symptoms. Learn the signs and how ProVision treats Demodex blepharitis.

What Is Demodex Blepharitis?

Demodex are tiny mites that naturally live in the hair follicles and oil glands of human skin — including the eyelash follicles. In small numbers, they're harmless. But when they overpopulate, they cause Demodex blepharitis: chronic inflammation of the eyelid margins that can significantly affect eye comfort, vision, and tear film quality.

Demodex blepharitis is far more common than most patients (and many doctors) realize. Studies suggest it affects up to 45% of adults — and the prevalence increases with age.

Signs and Symptoms of Demodex Blepharitis

Classic Signs

•Cylindrical dandruff (collarettes) at the base of eyelashes — the most specific sign
•Eyelid redness and swelling along the lash line
•Itchy, irritated eyelids — especially in the morning
•A gritty, foreign body sensation in the eyes
•Crusting around the lashes upon waking

Associated Symptoms

•Chronic dry eye that doesn't fully respond to artificial tears
•Blurry vision that fluctuates throughout the day
•Recurrent styes or chalazia (eyelid cysts)
•Sensitivity to light
•Eyelash loss or misdirected lashes

How We Diagnose Demodex at ProVision

Diagnosis is clinical — we examine the eyelid margins and lash bases under magnification using our slit lamp. The presence of cylindrical collarettes (waxy, sleeve-like debris at the base of lashes) is pathognomonic for Demodex infestation.

In some cases, we may epilate a lash and examine it under microscopy to directly visualize the mites.

Treatment Options at ProVision Eye Associates

Xdemvy (Lotilaner Ophthalmic Solution)

The first and only FDA-approved treatment specifically for Demodex blepharitis. Xdemvy is applied twice daily for 6 weeks and works by paralyzing and eliminating Demodex mites. Clinical trials showed significant reduction in collarettes and eyelid erythema.

ZEST (Zocular Eyelid System Treatment)

An in-office treatment using okra-based gel to deep-clean the eyelid margins, physically removing mites, debris, and biofilm. ZEST is comfortable, takes about 15 minutes, and provides immediate improvement in eyelid hygiene.

NuLids Pro

A gentle, motorized eyelid hygiene device used in-office to exfoliate the eyelid margins and reduce the Demodex population. Often combined with ZEST for comprehensive treatment.

Tea Tree Oil-Based Lid Hygiene

At-home maintenance using tea tree oil-based eyelid cleansers (such as Cliradex or Ocusoft Lid Scrub Plus) helps suppress Demodex between professional treatments.

Why Treating Demodex Matters

Untreated Demodex blepharitis doesn't resolve on its own. Over time, it can:

•Damage meibomian glands, worsening dry eye
•Cause permanent eyelash loss
•Lead to corneal inflammation (keratitis)
•Reduce the effectiveness of dry eye treatments

If you've been treated for dry eye without lasting improvement, Demodex may be an underlying cause that hasn't been addressed.
