Treatment of allergic diseases of eyelids and conjunctiva (conjunctivites and blepharoconjunctivites) often presents difficulties due to peculiarities of their pathogenesis - allergic and vascular reactions, disorder of lacrimal production, meibomian gland dysfunction, and possible bacterial contamination. It has been suggested to use Ocumethyl, which contains zinc sulfate (binding, drying, anti-inflammatory, and antiseptic effect), diphenhydamine hydrochloride (an Н1-antihistamine that decreases capillary permeability and helps resolve conjunctival and eyelid edema), naphazoline hydrochloride (a sympathomimetic notable for its strong, rapid, and long-lasting vasoconstrictive effect), and methylene blue (antiseptic effect, disintoxication, and antioxidant activity)...

Evaporative dry eye has gained increasing interest in recent years in academia, pharmaceutical, and medical device industries. The main cause of this type of dry eye is attributed to meibomian gland dysfunction (MGD). MGD is a diffuse abnormality of the meibomian glands characterised by terminal duct obstruction and eventually leading to signs and symptoms of dry eye. There have been only a few reported animal models of MGD, but recent advances are likely to lead to new models and better ways to assess the pathology in these animals...

BACKGROUND: Dry eye patients suffer from all kinds of symptoms. Sometimes, the clinical signs evaluation does not disclose any obvious difference in routine examination; in vivo confocal microscopy (IVCM) is a powerful tool for ocular surface disease. This study aimed to clarify meibomian gland (MG) alterations in dry eye patients with different symptoms and to compare the findings using IVCM. METHODS: A total of sixty patients were recruited, all subjected to Ocular Surface Disease Index (OSDI) and Salisbury Eye Evaluation Questionnaire (SEEQ), and questionnaires for the assessment of dry eye symptoms before clinical sign examinations were given to the patients...

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...

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 reviews and clinical trials using the Pub Med database...

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...

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: 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...
