Dry eye disease

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...

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...

For the last 20 years, a great amount of evidence has accumulated through epidemiological studies that most of the dry eye disease encountered in daily life, especially in video display terminal (VDT) workers, involves short tear film breakup time (TFBUT) type dry eye, a category characterized by severe symptoms but minimal clinical signs. An unstable tear film also affects the visual function, possibly due to the increase of higher order aberrations. Based on the change in the understanding of the types, symptoms, and signs of dry eye disease, the Asia Dry Eye Society agreed to the following definition of dry eye: "Dry eye is a multifactorial disease characterized by unstable tear film causing a variety of symptoms and/or visual impairment, potentially accompanied by ocular surface damage...

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...

Thyroid orbitopathy (TO) is an autoimmune disease that is complicated by ocular surface disorders, leading to discomfort. Dry eye is very prevalent in patients with TO. Recent studies on the pathogenesis of dry eye have focused on the inflammatory process, and some supporting evidence has been discovered. Because TO is a disorder of autoimmune origin, we assumed that the association between TO and dry eye is related to inflammation. Inflammation of the ocular surface in TO-related dry eye has not been well studied...

Tear fluids are a mixture of secretions derived from lacrimal glands, accessory lacrimal glands, conjunctiva, and meibomian glands. Compositional changes to tears occur in the normal state and during ocular surface disease, such as dry eye conditions. We have investigated compositional changes to tears after topical application of ophthalmic solutions, with regard to tear-specific proteins (secretory immunoglobulin A, lactoferrin, lipocalin-1, and lysozyme) and ocular surface mucin in normal and dry eye conditions using high-performance liquid chromatography...

BACKGROUND: Dry eye disease (DED) is multifactorial, affecting 5-34 % of the global adult population and reducing quality of life. The artificial tears or lubricants are the therapy most used for the treatment of DED, due to their low side effect profile, which attempt to modify the properties of the tear film. The aim of the present study was to evaluate the clinical efficacy of a fixed combination of xanthan gum and chondroitin sulfate preservative free on the ocular surface of patients with dry eye disease during 60 days of intervention...

Understanding the immunopathogenesis of autoimmune and inflammatory diseases is a prerequisite for specific and effective therapeutical intervention. This review focuses on animal models of two common ocular inflammatory diseases, dry eye disease (DED), affecting the ocular surface, and uveitis with inflammation of the inner eye. In both diseases autoimmunity plays an important role, in idiopathic uveitis immune reactivity to intraocular autoantigens is pivotal, while in dry eye disease autoimmunity seems to play a role in one subtype of disease, Sjögren's syndrome (SjS)...
