Blepharitis
Introduction
Blepharitis is inflammation of the edges of the eyelids, possibly with thickening scales, crusts, shallow ulcers, or redness and swelling at the edges of the eyelids. The inflammation is caused by certain infections, allergic reactions, and some skin conditions. The eyelids become irritated, red, and swollen and may burn and itch. Usually the diagnosis is based on symptoms and the appearance of the eyelids. Any underlying disorders are treated, and sometimes antibiotic ointments or drops, antiviral pills, corticosteroid ointment, artificial tears, or a combination is given.
