There are rare occasions in a field of science when significant advances occur in leaps and bounds, rather than in small, deliberate steps. This moment is imminent in the field of meibomian gland dysfunction (MGD)—and therefore in dry eye disease. The goals of the International Workshop on Meibomian Gland Dysfunction were twofold: first, to develop a consensus understanding of the meibomian gla...

PURPOSE To evaluate the sustained effect (up to 1 year) of a single, 12-minute vectored thermal pulsation (VTP) treatment in improving meibomian gland function and dry eye symptoms in patients with meibomian gland dysfunction and evaporative dry eye. METHODS The prospective, multicenter, open-label clinical trial included 200 subjects (400 eyes) who were randomized to a single VTP treatment (...

Purpose. This study aims to evaluate dry eye and ocular surface conditions of myopic teenagers by using questionnaire and clinical examinations. Methods. A total of 496 eyes from 248 myopic teenagers (7-18 years old) were studied. We administered Ocular Surface Disease Index (OSDI) questionnaire, slit-lamp examination, and Keratograph 5M. The patients were divided into 2 groups based on OSDI dr...

Meibomian gland dysfunction (MGD) may well be the leading cause of dry eye disease throughout the world. Although this condition affects the health and well-being of millions of people, there is no global consensus on the definition, classification, diagnosis, or therapy for MGD. To achieve such a consensus, the Tear Film and Ocular Surface Society (TFOS; http://www.tearfilm.org), a nonprofit o...

PURPOSE To characterize patients with ocular surface drying and a diagnosis of keratoconjunctivitis sicca (KCS). METHODS Patients with a prior diagnosis of KCS and symptoms of dryness or foreign-body sensation who also had vital staining of the interpalpebral fissure ocular surface in the absence of lid and ocular surface inflammation were entered into the study along with normal controls.
