What Causes Blepharitis?

Blepharitis occurs due to various factors that can be broadly categorized into two types.

1. Anterior Blepharitis: This type affects the outer edge of the eyelids where the eyelashes are located. It is commonly caused by:

• Bacterial infections, particularly Staphylococcus bacteria.

• Seborrheic dermatitis (dandruff of the scalp and eyebrows).

• Allergic reactions to eye makeup or other irritants.

2. Posterior Blepharitis: This type affects the inner edge of the eyelids, closer to the eye. It is often linked to:

• Dysfunction of the meibomian glands, which produce the oily layer of tears.

• Skin conditions such as rosacea or acne. l Hormonal imbalances that influence gland function.

Symptoms

Blepharitis manifests through a range of symptoms, which can vary in intensity:

• Redness and swelling of the eyelids.

• Burning or stinging sensations in the eyes.

• Crusty or flaky debris at the base of the eyelashes.

• Excessive tearing or dryness.

• Sensitivity to light (photophobia).

• Gritty or foreign body sensation in the eyes.

• Frequent blinking or irritation during contact lens use.
