DRY EYE SYNDROME, MEIBOMIAN GLAND DYSFUNCTION

The Tear Film and Ocular Surface Society achieved a consensus in 2011 for the definition of MGD as a chronic, diffuse abnormality of meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in glandular secretionThe core mechanisms of terminal duct obstruction are hyper-keratinization and altered lipid profile of meibumConventional treatments for MGD include warm compresses, lid cleansingIn 2015, intense pulsed light (IPL) was first proposed as a novel, emerging treatment for MGD
