Demodex Blepharitis Treatment in Rancho Santa Margarita, California

Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated February 2026

Demodex blepharitis is an inflammatory eyelid condition caused by microscopic Demodex mites living in eyelash follicles. When these mites multiply excessively, they trigger chronic inflammation, irritation, and damage to the meibomian glands. The condition affects approximately 25 million Americans and is characterized by distinctive cylindrical dandruff (collarettes) at the base of eyelashes.

Children in Rancho Santa Margarita can develop eyelid conditions like demodex blepharitis, which may affect vision development if untreated. Parents should watch for persistent redness, swelling, or crusting that doesn't resolve on its own.
