BACKGROUND: To investigate function and morphology of the meibomian gland (MG) in patients with thyroid eye disease (TED). METHODS: In this prospective case series study, patients with unilateral or bilateral TED were consecutively enrolled. The diagnosis of TED was based on the typical orbital findings and/or radiographic evidence. The disease activity of TED was classified according to the clinical activity score (CAS). Degrees of lagophthalmos and exophthalmos, blinking rates, and results of the Schirmer test 1 were also recorded...

PURPOSE: We hypothesized that women with primary (pSS) and secondary Sjögren syndrome (sSS; with systemic lupus erythematosus [SLE] or rheumatoid arthritis [RA]) have meibomian gland dysfunction (MGD). We sought to test our hypothesis. METHODS: Subjects with pSS, sSS + SLE, sSS + RA, and non-SS-related MGD were recruited from the Sjögren's Syndrome Foundation or outpatient clinics at Tufts University School of Dental Medicine or Brigham and Women's Hospital. The control population was recruited from the Greater Boston area...

All the components of the ocular surface and the lacrimal system are affected by aging. Aging induces lacrimal gland fibrosis, Meibomian gland dysfunction, loss of corneal sensitivity, decreased corneal cell density, impairment of immune defences, increased local inflammation associated with hormonal changes, conjunctivochalasis, lid abnormalities, etc. Furthermore, homeostasis of the ocular surface may be altered by various age-related systemic comorbidities and iatrogenic interventions. Altogether, aging is considered the most predominant risk factor for dry eye disease...

INTRODUCTION: Blepharitis and meibomian gland dysfunction are chronic inflammatory conditions with overlapping pathophysiology and symptomatology. Both microbial infection and seborrhea contribute to the pathophysiology and both may benefit from treatment with tea tree oil (TTO). We evaluated the therapeutic effect of eyelids scrubbing with TTO in a group of patients with lid margin disease. MATERIALS AND METHODS: Forty patients were recruited. Half of them received lid scrubbing with a TTO formula (Naviblef™) and the other half was treated by massage and cleansing...

PURPOSE: To perform qualitative and quantitative analysis of meibomian gland (MG) dropout in hematological patients before hematopoietic stem cell transplantation (HSCT) and to correlate it with both ocular surface and hematological characteristics. METHODS: This prospective study included 46 consecutive patients undergoing HSCT and 30 age- and sex-matched healthy controls. Noninvasive meibography of the lower eyelid, meiboscore (Pult scale), Schirmer test type I, tear film breakup time, and corneal and conjunctival staining were measured...

PURPOSE: To evaluate perioperative dry eye (DE) syndrome and meibomian gland dysfunction (MGD) parameters associated with persistent DE symptoms after cataract surgery. METHODS: We enrolled patients who underwent uncomplicated cataract surgery without previous ocular comorbidities and previous use of ophthalmic treatment except for artificial tears at a single tertiary hospital. Lipid layer thickness, meibomian gland (MG) dropout, tear breakup time, Oxford staining score, lid margin abnormality, meibum quality, meibum expressibility, MG orifice obstruction, MGD stage, Ocular Surface Disease Index (OSDI), and Schirmer test score were prospectively assessed in order at baseline and 1 and 3 months postoperative...

Louis Tong, Lim Shee Teng
Purpose/aims: Dry eye is a common multi-factorial disease characterized by tearfilm dysfunction. Diagnosis of dry eye requires documentation of tear status with non-invasive tear break up times (NIBUT), tear meniscal height (TMH), and tearfilm lipid layer. These parameters objectively assess tear stability and indirectly, the functional impact of meibomian gland dysfunction. While it is obvious that portable instrumentation gives broader access than fixed instrumentation, its value would be limited if it is unreliable and its precision and accuracy substantially worse than fixed instruments...

PURPOSE: This study evaluated relationships between meibomian gland loss (MGL) and age, sex, and dry eye. METHODS: Dry eye and MGL of the lower eyelid was evaluated from 112 randomly selected subjects (66 women; mean age 62.8; SD ±15.7; and age range: 19-89 years) from Horst Riede GmbH, Weinheim, Germany. In addition, subjects were grouped into dry eye and non-dry eye by the Ocular Surface Disease Index (OSDI) score, lid-parallel conjunctival folds and non-invasive break-up time...

Intense pulsed light (IPL) is a broad spectrum incoherent light which is produced by high-output xenon lamp. Since the invention of the first-generation IPL in 1994, IPL technology has been developing rapidly and extensively utilized in multiple fields relevant to dermatology across the world. In 2004, the fourth-generation IPL system was introduced with the optimal pulse technology (OPT) and has soon been used for cosmetic purposes all over the world. In 2002, Dr. Toyos found that the meibomian gland dysfunction (MGD) and dye eye disease (DED)symptoms of the rosacea patients who received IPL treatment have been improving significantly, therefore he started to explore the application of IPL system to treatment of dry eye disease...

Lipids secreted from the meibomian gland (meibum) form the superficial layer of the tear film and prevent water evaporation from the ocular surface and infection. Here, we identified the fatty acid (FA) elongases responsible for the synthesis of very long-chain FAs (VLCFAs) that constitute the meibum lipids. Elongation of VLCFAs (ELOVL)1 is primarily responsible for the production of saturated VLCFAs, whereas ELOVL1, ELOVL3, and ELOVL4 redundantly participate in the synthesis of monounsaturated VLCFAs. Gene disruption of Elovl1 in mice shortened acyl moieties in the 2 major meibum lipids: cholesteryl esters and wax esters...
