BLEPHARITIS
Blepharitis is inflammation of the eyelids. This is a common cause of irritated, red eyes. Blepharitis occurs when tiny oil glands located near the base of the eyelashes become inflamed or clogged. Blepharitis is often a chronic condition that is difficult to treat. Blepharitis can be uncomfortable and may be unsightly, but it is not contagious. Blepharitis and dry eyes often occur at the same time. Treating blepharitis may also prevent, reduce or eliminate dry eye symptoms.
MEIBOMIAN GLAND DYSFUNCTION
Bacteria in the eyelid biofilm also cause inflammation of oil-secreting meibomian glands in the eyelids. This causes a condition called meibomian gland dysfunction, which causes (and worsens) dry eye discomfort.
DEMODEX
Blepharitis usually is associated with an overgrowth of bacteria that live along the margins of the eyelids and at the base of the eyelashes. Over time, these bacteria multiply and create a structure called a biofilm. Parasitic eyelash mites called Demodex feed on the biofilm, which in turn leads to an overgrowth of these mites that causes a worsening of the eyelid inflammation.
TREATMENT OPTIONS
Typically blepharitis is treated with targeted lid hygiene practices and/or medicated eye drops, ointments, or wipes. Learn more each below:
