Blepharitis

What Is Blepharitis and What Causes It

Understanding what type of blepharitis you have is the first step toward effective treatment. The condition comes in two main forms, and knowing the difference helps guide the right care plan for your eyes.

The Two Main Types

Anterior blepharitis affects the outer edge of your eyelid where your eyelashes attach. This type is most often caused by bacteria or dandruff-like flaking from your scalp and eyebrows, and it includes staphylococcal, seborrheic, and Demodex-related subtypes.

Posterior blepharitis develops along the inner edge of your eyelid that rests against your eye. This form, also called meibomian gland dysfunction, involves the tiny oil glands inside your eyelids that become clogged or produce abnormal oils, disrupting your tear film and causing irritation.

Common Causes and Triggers

Several factors can lead to blepharitis or cause it to flare. Bacterial overgrowth on the eyelid skin is among the most frequent culprits, but many other triggers can contribute.

• Seborrheic dermatitis affecting the scalp and face
• Meibomian gland dysfunction, reducing the oil layer of your tears
• Rosacea, a skin condition linked to facial redness and eyelid inflammation
• Allergies or reactions to eye makeup or contact lens solutions
• Demodex mites on the eyelashes, often recognized by cylindrical flakes at the lash base called collarettes
• Atopic dermatitis or psoriasis
• Long-term contact lens wear or poor lens hygiene
• Certain glaucoma drops, especially those containing preservatives or prostaglandin analogs
• Use of isotretinoin
• Heavy eyeliner on the inner lid margin or eyelash extensions and adhesives

Who Is Most at Risk

Blepharitis can develop at any age, but adults over 50 experience it more frequently as meibomian gland function tends to decline with age. People with dandruff, oily skin, rosacea, or allergies also have a higher chance of developing it.

Dry eye disease and blepharitis frequently occur together, and each condition can make the other worse. Children can develop a form called blepharokeratoconjunctivitis, which carries a higher risk of corneal involvement and requires closer monitoring.

Recognizing the Symptoms of Blepharitis

Blepharitis symptoms often start gradually and can easily be mistaken for general eye irritation or dryness. Knowing what to look for helps you seek care at the right time before symptoms progress.

Early Warning Signs

Many people first notice blepharitis in the morning, when eyelids feel irritated or look slightly red along the lash line. You might find small flakes or crusts on your lashes when you wake up, or experience a gritty or burning sensation that comes and goes during the day.

• Cylindrical flakes or sleeves at the lash base, known as collarettes
• Eyelashes sticking together after sleeping
• Occasional lash misdirection or early lash loss

Everyday Symptoms

As blepharitis continues, symptoms typically become more noticeable and can affect your comfort throughout the day. Our team regularly hears patients describe a combination of the following.

• Red, swollen eyelid margins
• Itching or burning around the eyes
• Crusty or greasy flakes clinging to the eyelashes
• Eyes that feel dry, gritty, or excessively watery
• Sensitivity to light or increased blinking
• Recurrent styes (painful bumps on the lid) or chalazia (firm, painless lumps inside the lid)
• Frothy or foamy tears along the lid margin
• Lash loss, called madarosis, or misdirected lashes, called trichiasis

Symptoms That Require Urgent Attention

Most blepharitis symptoms develop gradually and respond well to proper care. However, some warning signs require you to contact our office promptly or seek urgent eye care without delay.

These signs can indicate a corneal infection, shingles (herpes zoster), or an orbital infection, all of which need urgent evaluation. Do not wait to be seen if you experience sudden vision changes, significant eye pain, or symptoms that worsen rapidly despite treatment.

How We Diagnose Blepharitis

Reaching the right diagnosis means looking closely at your eyelids, your tear film, and the overall health of your ocular surface. Our team takes a thorough approach so that your treatment plan addresses the actual cause of your symptoms.

What Happens During Your Exam

When you come in with eyelid concerns, we begin by reviewing your symptoms, how long you have had them, and anything that makes them better or worse. Your eye doctor will then examine your eyelids and lashes under the slit lamp, which is a device that uses bright light and magnification to see fine detail.

We look for collarettes, blocked glands, eyelash misdirection, and the quality of your tear film. We may also gently express your meibomian glands to assess the color and consistency of the oils they produce.

Additional Tests We May Use

In most cases, blepharitis can be identified based on what we see during your exam. When we need more information about the specific type or severity, we have several tools available.

• Tear film assessment to check for associated dry eye disease
• Eyelash examination for Demodex mites or other organisms
• Cultures or swabs if a bacterial or fungal infection is suspected
• Meibography imaging to evaluate meibomian gland structure
• Sampling of collarettes or lashes when Demodex is likely
• Point-of-care tear testing, such as osmolarity or inflammatory markers, when dry eye is significant

Conditions We Rule Out

Several other eye conditions share symptoms with blepharitis, including conjunctivitis (pink eye), allergic reactions, dry eye disease alone, styes, or chalazia. We also consider ocular rosacea, herpetic blepharoconjunctivitis, and eyelid lice.

In cases where one eye is consistently worse and lash loss is present, we evaluate for eyelid tumors. Some patients have more than one condition at the same time, and we will address all contributing factors in your care plan.

Treatment Options for Blepharitis

Treatment for blepharitis is tailored to the type of inflammation, its underlying cause, and the severity of your symptoms. Most patients do well with a combination of eyelid hygiene and targeted therapies.

Eyelid Hygiene as First-Line Care

Keeping your eyelids clean is the foundation of blepharitis treatment. A consistent daily routine removes bacteria, excess oils, and debris that accumulate along the eyelid margins and drive inflammation.

The most effective approach follows three steps. Begin with a warm compress on your closed eyelids for 5 to 10 minutes to soften oils and loosen debris. Follow with gentle lid massage directed toward the lash line to help express oil from the meibomian glands. Then clean the lid margins with an appropriate eyelid cleanser to remove loosened material.

Prescription Medications

When eyelid hygiene alone does not provide enough relief, we may recommend prescription medications. The choice depends on what is driving your blepharitis and how severe your symptoms are.

• Topical antibiotic ointment, such as erythromycin or bacitracin, applied to the lid margins at bedtime for anterior blepharitis
• Oral doxycycline or minocycline for posterior blepharitis or rosacea-related cases, with dosing and duration individualized to your situation
• Short-term low-dose steroid drops for significant inflammation, used with a taper plan and eye pressure monitoring
• Topical immunomodulators such as cyclosporine or lifitegrast when ocular surface inflammation or dry eye is present
• Lotilaner ophthalmic solution 0.25% or, in selected cases, topical ivermectin applied to the lash bases under clinical guidance, when Demodex is confirmed

Tetracycline-class antibiotics are not used during pregnancy, while breastfeeding, or in children under 8, and they can cause sun sensitivity and stomach upset. Steroid drops require close supervision because they can raise eye pressure and increase cataract risk over time. Do not use leftover steroid drops, and avoid wearing contact lenses while using steroid drops or antibiotic ointments unless specifically instructed by your eye doctor.

Treating Underlying Conditions

Blepharitis often develops alongside other health conditions that need their own attention. Managing these related issues is an essential part of getting your eyelid inflammation under control.

If you have seborrheic dermatitis, working with a dermatologist to treat your scalp and skin can reduce eyelid flares. For patients with rosacea or dry eye disease, treating those conditions typically improves blepharitis symptoms significantly. In some cases, dermatology-directed therapies for facial rosacea, including light-based treatments, may also benefit eyelid inflammation.

In-Office Procedures for Persistent Cases

Some patients with chronic or severe blepharitis benefit from professional treatments we can perform in our office when standard approaches have not provided enough relief. Candidacy is individualized, results vary, and many of these procedures are not covered by insurance.

Options include thermal pulsation treatments such as TearCare, iLux, or LipiFlow; microblepharoexfoliation; manual gland expression; and intense pulsed light therapy for ocular rosacea. Our team will discuss which options may be appropriate for your specific situation during your visit.

What to Expect from Treatment

Blepharitis is a chronic condition that requires ongoing management rather than a single course of treatment. Most patients notice meaningful improvement over 2 to 6 weeks of consistent care, though the timeline varies based on type and severity.

Symptoms typically improve gradually as inflammation decreases and eyelid health improves. Even after your eyes feel normal again, continuing your daily eyelid hygiene routine is essential to prevent flare-ups. With ongoing care, flare-ups tend to be shorter and milder over time.

Home Care and Daily Management

What you do at home every day has a significant impact on how well your blepharitis is controlled. A consistent routine paired with a few simple habits can make a meaningful difference in your comfort and long-term outcomes.

Daily Eyelid Cleaning Routine

Cleaning your eyelids once daily, typically in the evening, is the single most important step you can take. This removes the buildup of bacteria, oils, and debris that drive inflammation over time.

• Wash your hands thoroughly before touching your eyes or eyelids
• Apply a warm compress to your closed eyelids for 5 to 10 minutes
• Perform gentle lid massage toward the lash line immediately after warming
• Use a dedicated eyelid cleanser or hypochlorous acid spray designed for this purpose; baby shampoo is not recommended
• Gently scrub along the base of your eyelashes with your eyes closed
• Rinse well with clean water if your cleanser requires it
• Pat your eyelids dry with a clean towel

Using Warm Compresses Effectively

Warm compresses help melt the thickened oils inside your eyelid glands and reduce inflammation along the lid margin. Microwaveable eye masks tend to hold heat more evenly and consistently than a washcloth, which can help make this step more effective.

If you use a washcloth, soak it in comfortably warm water and test the temperature on your inner wrist before applying it to your eyelids to avoid burns. Hold the compress against your closed lids for 5 to 10 minutes, rewarming it as needed to maintain a steady temperature. Follow immediately with lid massage while the glands are still warm.

Lubrication and Environment

Dryness is a frequent companion to blepharitis, and addressing it directly supports your overall ocular surface health. Small adjustments to your daily environment and habits can meaningfully reduce discomfort.

• Use preservative-free artificial tears 2 to 6 times daily as needed for dryness
• Take regular blinking breaks during screen time and practice slow, complete blinks
• Use a humidifier in dry environments and avoid sitting directly in front of air vents or fans
• Consider a nighttime lubricating ointment if you tend to wake with significant irritation

Habits and Products to Avoid

Certain behaviors and products can irritate your eyelids and trigger a flare-up. Being aware of what comes into contact with your eyes helps keep symptoms more stable between visits.

• Avoid wearing eye makeup during active flare-ups, and regularly replace old makeup that may harbor bacteria
• Do not rub or touch your eyes with unwashed hands
• Stay away from smoky or dusty environments when possible
• Avoid baby shampoo on the eyelids, as it can be irritating to the ocular surface
• Avoid eyeliner on the inner lid margin and eyelash extensions or adhesives during flares
• Pause contact lens wear during flare-ups and discard your lens case before resuming wear

When Home Care Is Not Enough

If you have followed a consistent eyelid hygiene routine for several weeks without meaningful improvement, it is time to contact our office. Persisting or worsening symptoms may indicate that you need prescription treatment, care for an underlying condition, or an in-office procedure.

If symptoms have not improved after 4 to 6 weeks of home care, ask our team whether Demodex-directed therapy is appropriate for you and whether you may be a candidate for in-office treatments. Getting an updated assessment sooner rather than later helps prevent complications such as corneal involvement or chronic chalazia.

Long-Term Follow-Up Care

Making eyelid care a permanent part of your daily routine is the key to staying comfortable over the long term. Even when your eyes feel completely normal, continuing preventive measures helps avoid future flare-ups and keeps inflammation from returning.

Our team schedules follow-up visits to monitor your progress and adjust your treatment as needed. Patients with recurrent chalazia, trichiasis, or children with blepharokeratoconjunctivitis may need more frequent follow-up to protect the health of their cornea and vision.
