Blepharitis is inflammation of the eyelids, causing redness and itchiness, greasy scales at the lid margins, and crusts on the eyelashes.
It may be associated with skin disorders such as seborrheic dermatitis , or with bacterial infection or allergy.
Avoiding allergens, keeping the eyelids clean, and using an antidandruff shampoo often results in blepharitis clearing up by itself.
If it persists or recurs repeatedly, antibiotics may be prescribed
