Blepharitis Treatment

At Sitterle Vision Source & Dry Eye Center in San Antonio, we focus on diagnosing and treating blepharitis using modern therapies designed to reduce eyelid inflammation and restore healthy tear function.

If your eyelids are red, itchy, irritated, or crusty, you may be experiencing blepharitis, a common condition that causes inflammation along the eyelid margins.

Blepharitis often occurs alongside dry eye disease, because inflammation around the eyelids can disrupt the meibomian glands responsible for maintaining a healthy tear film.

With proper treatment, most patients experience significant improvement in comfort and eye health.

What Is Blepharitis?

Blepharitis is an inflammatory condition that affects the edges of the eyelids where the eyelashes grow.

It develops when bacteria, debris, or inflammation accumulate along the eyelid margin.

Over time, this buildup can irritate the eyelids and disrupt the function of the meibomian glands, which produce the oils necessary for a stable tear film.

Blepharitis is one of the most common eye conditions and frequently contributes to chronic dry eye symptoms.

There are two main types of blepharitis:

Anterior Blepharitis

This type affects the outer eyelid margin near the eyelashes.

It is often associated with bacteria or skin conditions such as dandruff.

Posterior Blepharitis

Posterior blepharitis occurs when inflammation affects the meibomian glands inside the eyelids, leading to meibomian gland dysfunction.

This form is closely linked with evaporative dry eye disease.

Symptoms of Blepharitis

Blepharitis symptoms can vary in severity but often include:

red or swollen eyelids
itching or burning sensation
crusting around the eyelashes
gritty or sandy feeling in the eyes
watery eyes
light sensitivity
eyelid irritation
frequent styes or chalazia

Some patients notice flaking or dandruff-like debris along the eyelashes, which can indicate bacterial buildup or Demodex mites.

Blepharitis symptoms are often worse in the morning and may fluctuate throughout the day.

What Causes Blepharitis?

Blepharitis can develop from several underlying causes.

Bacterial Overgrowth – Bacteria naturally live on the skin, but excessive buildup along the eyelids can trigger inflammation.
Meibomian Gland Dysfunction – Blocked or inflamed oil glands prevent proper oil secretion into the tear film.
Demodex Mites – Microscopic mites called Demodex can live within the eyelashes and contribute to chronic eyelid inflammation.
Skin Conditions – Conditions such as rosacea or seborrheic dermatitis may increase the risk of blepharitis.
Poor Eyelid Hygiene – Debris and oils can accumulate along the eyelid margins over time.

Because multiple factors often contribute to blepharitis, effective treatment typically requires addressing the underlying causes of inflammation.

How Blepharitis Affects Dry Eye

Blepharitis frequently contributes to dry eye disease.

Inflammation around the eyelids can interfere with the function of the meibomian glands, which produce the oil layer of the tear film.

When oil production decreases:

tears evaporate more quickly
the ocular surface becomes irritated
dry eye symptoms worsen

Treating blepharitis often leads to significant improvement in tear film stability and overall eye comfort.

Diagnosing Blepharitis

During a comprehensive eye examination, our doctors evaluate the eyelids and tear film to identify signs of blepharitis.

The evaluation may include:

examining the eyelid margins
evaluating meibomian gland function
assessing tear film stability
identifying signs of Demodex mites
evaluating inflammation of the ocular surface

Proper diagnosis helps determine whether blepharitis is related to bacteria, gland dysfunction, rosacea, or Demodex infestation.

Treatments for Blepharitis

Blepharitis treatment focuses on reducing inflammation, improving gland function, and restoring eyelid health.

At Sitterle Vision Source & Dry Eye Center, we offer several advanced therapies.

At-Home Care for Blepharitis

Daily eyelid care is often recommended to help manage blepharitis.

Your doctor may recommend:

warm compress therapy
eyelid cleansing products
omega-3 supplements
artificial tears
prescription medications when necessary

Maintaining consistent eyelid hygiene helps reduce inflammation and prevent flare-ups.

When to See an Eye Doctor

You should schedule an evaluation if you experience:

persistent eyelid irritation
crusting along the eyelashes
frequent styes
chronic dry eye symptoms
burning or gritty eyes

Early treatment helps prevent chronic inflammation and long-term damage to the meibomian glands.

FAQ About Blepharitis

Is blepharitis contagious?

Blepharitis is not contagious. It is usually caused by bacteria, gland dysfunction, or inflammation.

Can blepharitis be cured?

Blepharitis is often a chronic condition, but treatments can significantly reduce symptoms and improve eyelid health.

What causes crusty eyelashes?

Crusting along the eyelashes can occur when bacteria, debris, or Demodex mites accumulate along the eyelid margins.

Can blepharitis cause dry eye?

Yes. Blepharitis can interfere with meibomian gland function, which leads to evaporative dry eye disease.

Schedule a Dry Eye Evaluation

If you are experiencing symptoms of blepharitis or chronic eyelid irritation, a comprehensive eye exam can help determine the best treatment options.
