  Blepharitis is often caused by a bacterial infection in, on, and around the eyelids, but skin conditions, acne growth, or hygiene can also cause it. […] Your skin has bacteria all over it; sometimes, these bacteria can spread and grow in hair follicles, including eyelashes. These intruders can irritate the eyelash hair follicles, ultimately resulting in blepharitis. This condition can also be caused by mites or dandruff inflaming the area. […] But if too many Demodex mites spread to your eyelashes, they can inflame the area. The immune system may have a response and try to flush them out, or the mites themselves cause a bacterial infection by carrying bacteria to the follicles around the eyelids. This can often cause blepharitis to develop as the follicles start to become infected.

  Blepharitis refers to inflammation of the eyelid margins and may be divided into two types: […] The causes of blepharitis can be divided into anterior and posterior. […] The two predominant causes of anterior blepharitis are Staphylococci infection and Seborrhoeic type. […] Staphylococcus blepharitis: pathophysiology remains unclear, but the mechanism is thought to involve damaging effects of bacterial exotoxin production and cell-mediated immunity. […] Seborrhoeic blepharitis: closely linked with the common skin condition seborrhoeic dermatitis (present in ~95% of people with seborrheic blepharitis). […] Other infections that can lead to anterior blepharitis include: Pseudomonas, Streptococci, Propionibacterium, Corynebacterium, Moraxella. […] The underlying pathophysiology of MGD / posterior blepharitis is thought to be epithelial hyperkeratinisation, which results in gland obstruction, stasis of meibum, dilation of glands, and gland dropout.

[…] Chronic blepharitis has been associated with exposure to chemical fumes, smoke, smog, and other irritants. […] Acute blepharitis is most commonly due to allergy, drug toxicity, or chemical reaction. […] Posterior blepharitis is principally related to dysfunction of the meibomian glands. Alterations in secretory metabolism and function lead to disease. The meibomian secretions become more waxlike and begin to block the gland orifices. The stagnant material becomes a growth medium for bacteria and can seep into the deeper eyelid tissue layers, causing inflammation.

  Blepharitis may be acute (ulcerative or nonulcerative) or chronic (caused by meibomian gland dysfunction, seborrheic blepharitis, Demodex infestation). […] Acute ulcerative blepharitis is usually caused by bacterial infection (usually staphylococcal) of the eyelid margin at the origins of the eyelashes; the lash follicles and the meibomian glands are also involved. It may also be due to a virus (eg, herpes simplex, varicella zoster). […] Chronic blepharitis is noninfectious inflammation of unknown cause. Meibomian glands in the eyelid produce lipids (meibum) that reduce tear evaporation by forming a lipid layer on top of the aqueous tear layer. In meibomian gland dysfunction, the lipid composition is abnormal, and gland ducts and orifices become inspissated with hard, waxy plugs. […] Many patients with seborrheic blepharitis have seborrheic dermatitis of the face and scalp or acne rosacea.

• #84 Blepharitis – Valerie Saw

  https://valeriesaw.com/london-dry-eye-clinic/blepharitis/

  Blepharitis is very common. The commonest underlying problem in Blepharitis is dysfunction and blockage of the Meibomian oil glands in the eyelids. Meibomian oil glands do not work well when we are stressed, or have not had enough sleep. Dysfunction of the Meibomian oil glands can be associated with a skin condition called rosacea. Seborrhoeic dermatitis is another skin condition associated with blepharitis. When Meibomian oil glands are dysfunctional, rather than producing clear oil they become blocked and filled with a waxy whitish secretion. This causes 3 main eye problems: There is no clear oil to keep the surface of the eyes moist and keep the vision smooth and clear, so dry eye occurs. The thickened waxy secretion acts like a gritty foreign body, causing irritation and itchiness. Bacteria including Staphylococcus can grow in the thickened secretions, adding to the discomfort. Anterior blepharitis has sometimes also been linked to Demodex mites.
