BLEPHARITIS
DEFINITION OF BLEPHARITIS
Blepharitis is the inflammation of the eyelid margins, usually caused by bacterial infections, clogged oil glands, or skin conditions like dandruff or rosacea. It can affect people of all ages and may contribute to dry eyes and discomfort.
RISK FACTORS OF BLEPHARITIS
- Bacterial infections
- Seborrheic dermatitis
- Poor eyelid hygiene
- Chronic dry eyes
- Meibomian gland dysfunction (MGD)
SYMPTOMS
The eyelid margins (edges where lashes grow) appear swollen or reddish.
Inflammation and irritation trigger itching.
Usually felt along the eyelid margins or within the eyes themselves.
Yellowish or whitish flakes or crusts at the lash line, similar to dandruff.
Lids may feel sticky, especially after waking up.
TREATMENT TYPES
warm compresses, lid scrubs
for bacterial infections
Topical steroids: Short-term use of corticosteroid eye drops or ointments (e.g., Loteprednol) for flare-ups.
Steroid + antibiotic combos: Used when inflammation and infection coexist.
Purpose: Relieve dry eye symptoms associated with blepharitis.
Choose: Preservative-free artificial tears for long-term use.
Used in chronic dry eye caused by blepharitis to conserve tears by blocking tear drainage ducts.
FAQS
Blepharitis is a common, chronic inflammation of the eyelids, particularly at the base of the eyelashes. It can cause red, swollen, itchy eyelids and a gritty, burning sensation in the eyes. It’s often related to skin conditions, bacterial overgrowth, or problems with the eyelid’s oil glands.
Several factors can contribute, including:
Bacterial buildup (especially Staphylococcus)
Dysfunction of oil-producing meibomian glands
Dandruff (seborrheic dermatitis)
Rosacea
Allergies or environmental irritants
Mite infestations (Demodex)
No, blepharitis is not contagious. It is usually caused by internal factors (like gland dysfunction or skin conditions), not infections that spread between people.
A doctor can usually diagnose it through a clinical eye exam using a slit lamp to look at your eyelids, oil glands, and eyelashes. No special tests are usually required.
Blepharitis is often chronic, meaning it may not be fully curable, but it can be well-managed with consistent eyelid hygiene and proper treatment. Many people keep symptoms under control long-term.
