Classification

There are two types of Blepharitis:

1. Anterior blepharitis affects the front of the eyelids near the eyelashes. The causes are seborrheic dermatitis (similar to dandruff) and occasional infection by Staphylococcus bacteria.
2. Posterior blepharitis affects the back of the eyelids, the part that makes contact with the eyes. This is caused by the oil glands present in this region. It is by far, the most common type of blepharitis.
