Different types of blepharitis
Anterior blepharitis: this blepharitis affects the outer part of the eyelids: the skin and eyelashes. Also, the eyelid is red, swollen often with small scabs at the root of the eyelashes.
Posterior blepharitis: this blepharitis affects the rim and the inside of the eyelid, which is in contact with the eye, and the Meibomian glands that are there. In this case, white dots, or styes or chalazions may appear on the edge of the eyelids.
Anterior and posterior blepharitis: this type of blepharitis affects both: the external part and the edge of the eyelid.
Blepharitis often affects both eyes at the same time. In some cases, blepharitis is associated with chalazions, styes and/or to dry eye.
