Blepharitis and Ocular Surface Disease
Blepharitis describes a constellation of symptoms generally related to inflammation of the posterior and anterior eyelid margins.
Typically presents with a combination of symptoms including (but not limited to), itching and swelling of the eyelids, burning or otherwise dry and irritated eyelids, crust or flakes on eyelashes, eyelids sticking together upon waking, or a foreign body sensation
Untreated blepharitis can lead to ocular surface disease, severe infection, permanent alterations to the eyelid margin and, eventually, vision impairment and loss
Blepharitis affects at least 20,000,000 people per year in the United States.
