Blepharitis (Eyelid Inflammation): Symptoms, Diagnosis, and Treatment
Blepharitis is one of the most common eyelid conditions. Many patients perceive the problem as a temporary eye irritation for a long time, but the inflammation can persist for months and periodically worsen. Without proper treatment, symptoms often recur, and the condition of the ocular surface gradually worsens.
In our practice, we view eyelid inflammation as a condition that requires not only addressing the symptoms but also identifying the underlying cause.

Why does blepharitis develop?
The causes of the problem can vary. That's why an examination is always performed before prescribing therapy.
Meibomian Gland Dysfunction
One of the most common causes is considered to be dysfunction of the glands located in the eyelids.
When the meibomian glands produce insufficient secretion or its composition changes, the tear film is disrupted. This results in dry eye, irritation, and persistent inflammation.
Meibomian gland dysfunction often underlies chronic forms of the disease and requires separate treatment.
Infection, Demodex, and Other Causes
Inflammation can be caused by bacteria, increased microbial growth on the eyelid skin, or parasitic factors.
Demodicosis is a special case. Excessive Demodex mite proliferation increases irritation, itching, and inflammatory changes in the eyelash margin.
In some patients, the problem develops after previous infections or due to a combination of several factors.
Risk factors: dry eye, allergies, cosmetics, chronic diseases
There are conditions that increase the likelihood of developing the disease or exacerbate its symptoms.
These include:
- Dry eye
- Allergic reactions
- Use of low-quality cosmetics
- Chronic skin diseases
- Poor eye hygiene
- Prolonged visual strain
That's why the doctor evaluates not only the condition of the eyelids but also the overall condition of the ocular surface.
How does blepharitis manifest itself?
The clinical presentation depends on the form of the disease and the severity of the inflammatory process.
Itching, burning, redness, and swelling
The most common complaints are itching of the eyelids and a feeling of irritation. Patients may note a burning sensation, heaviness, and a constant urge to rub their eyes.
Redness of the eyelids and slight swelling of the tissues are also common. Symptoms worsen in the evening or after prolonged computer work.
Many patients describe these manifestations as the first signs of blepharitis.
Crusting, scaling, and sticking together of eyelashes
In some forms, scales and dense deposits appear on the eyelash margins.
In the morning, patients may notice crusting of the eyelashes, which makes it difficult to open the eyes after sleep. In severe cases, painful changes in the eyelid margin occur.
Tearing, dryness, and a gritty sensation in the eyes
Despite increased tear production, many patients simultaneously experience severe dryness of the ocular surface.
The disease is characterized by:
- Tearing
- Sensation of grit in the eyes
- Foreign body sensation
- Periodic blurred vision
- Visual discomfort
Impaired tear film quality is one of the reasons for the persistence of symptoms even after the inflammation has subsided.
When to see an ophthalmologist
If symptoms persist for several weeks, worsen, or return regularly, you should not delay an examination.
It is especially important to seek help if severe Swelling, pain, blurred vision, purulent discharge, or signs of complications. In these situations, a specialist examination and a full diagnosis of blepharitis are necessary.
Types of blepharitis
This problem encompasses several clinical forms, which differ in their causes and manifestations.
Anterior Blepharitis
In this form, inflammation is localized primarily in the area of the ciliary margin. Patients complain of irritation, plaque formation, and skin changes.
Posterior Blepharitis
This form is more often associated with glandular dysfunction. Therefore, it is often accompanied by changes in secretion and dysfunction of the meibomian glands.
Squamous and Ulcerative Blepharitis
The squamous form is accompanied by the appearance of plaque and scales on the eyelashes. It is characterized by skin irritation and constant discomfort.
In the ulcerative form, the inflammation is more severe. Painful crusts and areas of tissue damage may form on the eyelid margin.
Demodectic Blepharitis
Demodectic blepharitis is considered a separate form. Its development is associated with the activity of the Demodex mite.
This type is characterized by itching, repeated exacerbations, and is associated with chronic irritation of the eyelash margin.
Comparison table of types of blepharitis
| Type of blepharitis | Main manifestations | What is important in treatment |
|---|---|---|
| Scaly | Itching, redness, flakes on the eyelashes | Eyelid hygiene, inflammation control |
| Ulcerative | Painful crusts Eyelashes, eyelid margin damage | Mandatory medical examination |
| Meibomian | Dryness, heaviness of the eyelids, impaired secretion | Warm compress, eyelid massage, correction of the underlying cause |
| Demodectic | Relapses, itching, connection with Demodex | Confirmation of diagnosis and specialized care |
General information
How is diagnosis performed?
The correct treatment can only be selected after determining the type of disease and assessing the condition of the ocular surface.
Examination of the eyelids and lash line
During the appointment, the doctor assesses the condition of the skin, eyelashes, and eyelid margin. An examination can identify signs of inflammation, glandular changes, and the nature of tissue damage.
This is the stage where a full diagnosis of blepharitis begins.
Evaluation of the ocular surface and tear film
The quality of the tear film and the condition of the ocular surface are also assessed.
This approach helps identify concomitant dry eye syndrome, which often contributes to inflammation and influences the course of the disease.
Additional tests if needed
If the clinical picture requires clarification, the doctor may prescribe additional tests.
These tests help rule out demodicosis, allergic reactions, concomitant conjunctivitis, or other causes of complaints.
"In our practice, we always start with identifying the cause of eyelid inflammation rather than with universal drops. This approach helps us choose the right treatment, quickly relieve symptoms, and reduce the risk of recurrence," says an ophthalmologist.
Frequently Asked Questions
Is it possible to completely cure blepharitis?
Is blepharitis contagious?
Why does blepharitis frequently recur?
When is a follow-up appointment necessary?
A follow-up consultation is necessary if symptoms persist, worsen, or return after improvement.
A follow-up examination helps assess the effectiveness of therapy and promptly adjust treatment.
If severe pain, severe swelling, blurred vision, photophobia, or fever occur, consult a doctor as soon as possible.

What is blepharitis and why is it dangerous?
Blepharitis is a chronic inflammation of the eyelid margins, affecting the eyelash margin, eyelid glands, and surrounding tissues. The disease can present in various forms and can be accompanied by mild discomfort or severe complaints.
How Eyelid Inflammation Affects Quality of Life
Even moderate eyelid inflammation can significantly impact daily activities. Patients complain of itching, burning, a feeling of heaviness, and rapid eye fatigue.
With prolonged progression, persistent visual discomfort, difficulty working at a computer, and decreased tolerance of contact lenses may occur. Some patients report that their eyes tire more quickly during reading and visual strain.
Why Blepharitis Shouldn't Be Ignored
If inflammation persists for a long time, it can affect not only the eyelid margin but also the ocular surface. In some cases, blepharoconjunctivitis, glandular dysfunction, and chronic tissue inflammation develop.
Furthermore, the disease can be accompanied by relapses and periods of exacerbation, which become increasingly severe without proper treatment.
