Meibomian Gland Dysfunction & Dry eye


Three layers of healthy tear flim


Meibomian gland dysfunction (MGD) affects 86% of dry eye sufferers. People with meibomian gland dysfunction don't produce enough of the lipid or oil component of health tear file and this causes their eyes to dry out. Healthy tear film is composed of three layers: the mucin layer, the aqueous layer and the lipid layer. The lipid layer is the outermost tear film layer; it's job is to lubricate the eye and prevent evaporation of tears. When not enough lipid is produced by the meibomian glands, excessive evaporation occurs, causing dry eye disease.


MGD is a chronic, diffuse abnormality of the meibomian glands commonly characterized by terminal duct obstruction and/or changes in the quantify or quality of the lipid secreted by the gland. MGD is diagnosed by observing the structure of the meibomian glands using LipiScan and examining their secretions.


MGD affects the health of the surface of the eye. MGD can result in alteration of the tear film and may lead to symptoms of eye irritation, inflammation and ocular surface disease.


Thermal Pulsation such as LipiFlow is a safe and effective treatment for MGD.
