Ocular blepharitis (dandruff on the eye) is an inflammation of the eyelid margin. It may appear alone or be combined with staphylococcal blepharitis or Meibomian gland dysfunction. The inflammation is located on the anterior margin of the eyelid, and may form oily or greasy crusts on the eyelids, eyelashes, eyebrows, and scalp.
Patients with seborrheic ocular blepharitis usually have increased Meibomian gland secretions, which become opaque. These secretions can cause the sensation of dandruff on the eye, a common discomfort.
