Blepharitis is a condition that affects the eyelids and is characterized by inflammation, redness, itching, and irritation. It may be caused by bacterial or viral infections, allergies, or skin conditions such as seborrheic dermatitis.

Blepharitis is a common condition that affects people of all ages, genders, and races.

Causes of Blepharitis

Blepharitis is caused by several factors including:.

Bacterial or viral infections: Staphylococcus aureus is the most common bacterial infection associated with blepharitis. This type of bacteria can thrive on the skin and hair follicles of the eyelids and cause inflammation and irritation.
Allergies: Some people may develop blepharitis due to allergic reactions to pollen, dust, or animal dander. Allergic reactions can cause inflammation of the eyelids and lead to the development of blepharitis.
Skin conditions: Blepharitis is also associated with skin conditions such as seborrheic dermatitis and rosacea. These conditions cause inflammation and irritation of the skin and may lead to the development of blepharitis.
Mites: Demodex folliculorum and Demodex brevis are microscopic mites that live in the hair follicles of the eyelids. They can cause inflammation and irritation and may be associated with the development of blepharitis.
Medications: Some medications such as isotretinoin (Accutane) can cause blepharitis as a side effect.
