Demodex is a small mite, or parasite that can reside in our hair follicles and sebaceous glands. Demodex is contracted and spread by either direct contact or dust containing eggs.

Demodex causes symptoms such as: itching, foreign body sensation, redness, crusting, blurry vision, and burning. All of these symptoms can overlap with dry eye disease.

About 85% of patients with Demodex also have meibomian gland dysfunction.


Treatments for demodex include tea tree oil, shampoos, and lid scrubs, as well as in-office removal and prescription for inflammation.
