Blepharitis is a common eyelid inflammation that sometimes is associated with a bacterial eye infection, symptoms of dry eyes or certain types of skin conditions such as acne rosacea.
Blepharitis has two main forms:
Anterior blepharitis, affecting the outside front of the eyelid where eyelashes are attached.
Posterior blepharitis, linked to dysfunction of meibomian glands within the eyelids that secrete oils to help lubricate the eye.
It’s common to have a mixture of both anterior and posterior forms of blepharitis at the same time, but in different degrees of severity.
