meibomian gland dysfunction

Hyo Myung Kim, Youngsub Eom, Jong Suk Song
Meibomian gland dysfunction (MGD) is a leading cause of dry eye disease (DED). Meibomian gland dysfunction is divided into two major categories based on meibomian gland secretion: low delivery and high delivery. The low-delivery states are further classified as either hyposecretory or obstructive subtype, and the high-delivery state is termed "hypersecretory MGD." Two parameters are commonly used to evaluate meibomian gland function: lipid layer thickness and meibum quality and expressibility. To evaluate the morphology of meibomian glands, meibography is used to detect meibomian gland dropout...

PURPOSE: To observe reversibility of meibomian gland (MG) dropout and analyze correlated factors and to compare the treatment efficiency with and without eyelid hygiene in patients with meibomian gland dysfunction (MGD). METHODS: Consecutive 78 eyes of 78 MGD (stage 2-3) patients who finished follow-up examination after 1-month of treatment were recruited in this retrospective study. All patients were treated with artificial lubricant and eyelid hygiene. Related ocular surface evaluation and meibomian gland assessment were examined...

The dry eye disease (DED) is a chronic multifactorial disorder of the tears that also involves the ocular surface, the lacrimal glands, and meibomian dysfunction. Furthermore, DED is often associated with Sjögren's syndrome (SS) and other autoimmune disorders. Sometimes, this chronic or subclinical condition is difficult to diagnose and treat, due to its heterogeneity. Areas covered: A literature search of relevant publications about treatment of DED was performed. All relevant articles published between 2011 and 2016 were identified through a computerized search for review and clinical trials using Pub Med database...

PURPOSE: We aimed to compare the tear meniscus measurements using strip meniscometry (SM) and Keratograph5M (K5M) between 3 subtypes of dry eye disease patient groups, classified according to the presence of meibomian gland dysfunction (MGD), and normal subjects. METHODS: We enrolled 145 eyes from 145 subjects and measured the tear meniscus using SM and K5M, tear film breakup time, ocular surface staining, and ocular surface disease index; the Schirmer test; and examined lid margins and meibomian glands...

Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and Meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants...

PURPOSE: To investigate the efficacy of eyelid margin cleansing with ofloxacin ophthalmic ointment in obstructive meibomian gland dysfunction (MGD) patients. METHODS: Thirty-one eyes of 31 patients diagnosed with obstructive MGD were enrolled. All subjects were instructed to rub the eyelid edge with ofloxacin eye ointment once daily prior to bathing. Lid margin abnormalities, meibum properties, and tear stability were observed before and 3 months after ointment treatment...

PURPOSE: To evaluate changes in the tear film lipid layer thickness (LLT) after cataract surgery and the effects of cataract surgery on dry eye syndrome (DES) and meibomian gland dysfunction (MGD). METHODS: LLT measurements obtained using the LipiView interferometer, tear break-up time (TBUT) measurements, Schirmer's tests, Oxford staining scores, lid margin and meibomian gland findings, and the Ocular Surface Disease Index (OSDI) questionnaire scores were evaluated before and one and three months after cataract surgery...

Meibomian gland dysfunction (MGD) is considered the most common cause of dry eye disease (DED). Sex hormones seem to play a role in the pathogenesis of MGD although their involvement is not completely understood. Therefore, in the present study we evaluated the effect of dihydrotestosteron (DHT) and estradiol (β-Est) on an immortalized human meibomian gland epithelial cell line (HMGEC). Protein expression of sex hormone receptors in HMGEC was investigated by western blot. Ultrastructural morphology, Sudan III lipid staining, cell proliferation as well as vitality assays were performed...

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 (treatment group) or twice-daily, 3-month, conventional warm compress and eyelid hygiene therapy (control group)...

PURPOSE: Researchers have hypothesized that treatment with cyclosporine A (CyA), interleukin-1 receptor antagonists (IL-1RA; e.g., anakinra), P2Y2 receptor agonists (e.g., uridine triphosphate; UTP), and rebamipide may alleviate human meibomian gland dysfunction (MGD) and/or dry eye disease. Investigators have also proposed that prostaglandin analogues (e.g., bimatoprost) may induce MGD. Our goal was to determine whether these compounds directly influence human meibomian gland epithelial cell (HMGEC) function...

Meibomian glands are a modified type of sebaceous glands within the eye lid, which produce an oily secretion important for the stabilization and the prevention of evaporation of the tear film. The holocrine secretory mode of Meibomian glands is characterized by the centripetal movement, the maturation and finally degeneration of the acinar epithelial cells. The process of maturation and degeneration is paralleled by altered expression pattern of certain proteins and the intracellular accumulation of Meibomian gland lipids...

PURPOSE: To determine the effects of clinical variables, including age, sex, history of refractive or cataract surgery, contact lens use, and ocular surface and meibomian gland parameters on the lipid layer thickness (LLT) in normal subjects and patients with dry eye syndrome (DES). METHODS: A total of 64 normal subjects and 326 patients with DES were enrolled, and they underwent measurements of LLT with a LipiView interferometer and tear meniscus height using optical coherence tomography, tear film break-up time (TBUT) determination, ocular surface staining, Schirmer's test, examination of the lid margins and meibomian glands, and assessment using the Ocular Surface Disease Index (OSDI)...

Meibomian gland dysfunction (MGD) is believed to be the leading cause of dry eye (DE) disease worldwide. The connection between aging and MGD has long been recognized. However, few studies have addressed the relationship between MGD and hormone replacement therapy (HRT) in perimenopausal women, and not have examined the prevalence of MGD in perimenopausal women. The purpose of this study was to address and evaluate the possible relationship between MGD and HRT in perimenopausal women.The results suggest that perimenopausal women have a high prevalence of DE related to perimenopausal symptoms...

PURPOSE: The aim of the study was to understand natural changes of meibomian glands (MG) that occur with aging in the absence of any ocular pathology or ocular discomfort symptoms, to differentiate between "age normal" and pathologic or dysfunctional changes of the MG. METHODS: A total of 185 subjects (109 females) with no pre-existing ocular and systemic abnormalities were recruited and divided into four age groups: 25 to 34, 35 to 44, 45 to 54, and 55 to 66 years...
