What is Blepharitis?
Blepharitis is inflammation of the eyelids, often affecting both eyes along the edges. It's a chronic condition that can't be cured but can be managed effectively. As Dr. A Rauf from Sterling Eye Clinic, I've seen how this condition impacts daily life, but with proper care, symptoms can be minimized.
According to the Mayo Clinic, blepharitis results from the immune system's response to foreign substances, leading to swelling and irritation. It's not contagious and rarely causes permanent vision damage.
Types of Blepharitis
There are two main types:
- Anterior Blepharitis: Affects the front edge of the eyelids where lashes attach. Often caused by bacteria (staphylococcal) or dandruff (seborrheic), per AOA.
- Posterior Blepharitis: Involves the inner eyelid edge, linked to meibomian gland dysfunction, creating a bacterial-friendly environment.
Causes of Blepharitis
Common causes include:
- Bacterial overgrowth on the eyelids.
- Clogged oil glands near the lashes.
- Skin conditions like rosacea or seborrheic dermatitis (NHS).
- Allergies to eye makeup or contact lens solutions (Mayo Clinic).
- Eyelash mites or lice (less common).
In some cases, the exact cause remains unknown, but underlying conditions like dry eyes increase risk.
Risk Factors
Factors that heighten your risk:
- Scalp dandruff or eyebrow flakes.
- Rosacea or other inflammatory skin issues.
- Allergies, including to eye products.
- Dry eye syndrome.
