Anterior blepharitis is commonly caused by bacteria (staphyloccus blepharits) or dandruff of the scalp and eyebrows (seborrheic blepharitis). It may also occur due to a combination of factors, or less commonly may be the result of allergies or an infestation of lice on the eyelashes.
Blepharitis is inflammation of the eyelid margin. It's common and treatable. There are several possible causes of blepharitis, including: Bacterial eyelid infection; Meibomian gland dysfunction (MGD) Dry eyes; Fungal eyelid infection; Parasites (Demodex eyelash mites) Some eye doctors believe blepharitis actually is a precursor of meibomian gland dysfunction and dry eyes, rather than being caused by these conditions.
