Blepharitis / Demodex
Blepharitis
Blepharitis is a common and chronic inflammation of the eyelids, typically affecting the part where the eyelashes grow. It's often caused by bacterial overgrowth on the skin, clogged oil glands, or other underlying conditions. Symptoms may include redness, itching, and irritation of the eyelids, as well as crusty debris at the base of the eyelashes. While it's not usually a serious condition, blepharitis can be uncomfortable and persistent, requiring proper eyelid hygiene, warm compresses, and sometimes medication for management.
Demodex
Demodex refers to tiny mites that naturally inhabit human skin, particularly the hair follicles and oil glands. The two main species that affect humans are Demodex folliculorum and Demodex brevis. While these mites are generally harmless in moderate numbers, an overgrowth can lead to a condition called demodicosis, often associated with skin issues such as rosacea or certain types of blepharitis. Demodex mites feed on skin cells and oils and are most active during the night. Maintaining good skin hygiene and addressing underlying skin conditions are key in managing Demodex-related concerns.
