Meibomian gland dysfunction

Disease of the meibomian glands of the eyelid

Meibomian gland dysfunction is a chronic disease of the meibomian glands, which is commonly characterized by obstruction of the end of the duct that delivers the secretion produced by the glands to the eye surface, which prevents the glandular secretion from reaching the ocular surface. The dysfunction could be that the amount of secretion produced may be abnormal. Dysfunction could also be related to the quality of the meibum produced. MGD may result in evaporative dry eye, blepharitis, chalazion, unsealed lid during sleep, and meibomian gland atrophy.
