Demodex Blepharitis (DB): What You Should Know
Demodex blepharitis—also known as DB—is an eyelid disease caused by an infestation of Demodex mites, a common mite found on humans.1,2
*It’s estimated that approximately 25 million eye care patients in the US are affected by DB.3,4
Crusties (collarettes) around the base of the eyelashes signal a DB condition.1,3
DB can easily be overlooked by patients due to similarities with other eye diseases.1
When left untreated, DB can leave you more prone to other eye-related diseases.1
Patients with DB may experience eyelid redness, crusties (collarettes), irritation, itching, swelling, misdirected eyelashes, and inflammation.1-3,5
