Blepharitis
Causes of Blepharitis
Disorders that may cause blepharitis include bacterial (typically staphylococcal) infection of the eyelids or the ducts of the deeper glands that open at the edges of the eyelids, certain viral infections (usually Herpes Simplex Virus (HSV) Infections ), and allergic reactions (to pollens or sometimes to eye makeup and/or eye drops). Skin conditions such as Seborrheic Dermatitis , Another cause is inflamed, blocked oil glands at the edge of the eyelids (called meibomian gland dysfunction), which can be caused by seborrheic dermatitis or rosacea. Eye drops and eye makeup can trigger allergic reactions that cause blepharitis (called contact sensitivity allergic blepharitis). Sometimes the inflammation has no known cause.
