Pathology and pathogenesis of bovine skin and meibomian gland demodicosis

Immunology and pathogenesis of canine demodicosis.

Demodex mites colonized the hair follicles and sebaceous glands of mammals millions of years ago and have remained relatively unchanged in this protected ecologic niche since then. The host immune system detects and tolerates their presence. Toll-like receptor-2 of keratinocytes has been demonstrated to recognize mite chitin and to elicit an innate immune response. The subsequent acquired immun...

Meibomian Gland Dysfunction and Hypercholesterolemia

High cholesterol is a known risk factor for ischemic heart, cerebrovascular, and peripheral vascular disease. Previous studies have postulated that hypercholesterolemia (defined as total cholesterol of at least 200 mg/dL) also plays a role in the development of meibomian gland dysfunction (MGD). In this observational, case-control study, Pinna et al. investigated the correlation between MGD and...

Growth of meibomian gland tissue after intraductal meibomian gland probing in patients with obstructive meibomian gland dysfunction

PURPOSE To investigate the impact of meibomian gland probing (MGP) on meibomian gland (MG) area from the upper lids of patients with obstructive meibomian gland dysfunction (o-MGD). METHODS Retrospective study comparing pre-MGP/post-MGP non-contact infrared meibography results in patients with o-MGD, viewing signs of MG growth within total measurement field. RESULTS Post-MGP meibography of ...

Meibomian gland dysfunction

Meibomian gland dysfunction.

Blepharitis is probably the most common disease entity seen in the general ophthalmologist's office. A significant proportion of these cases are secondary to meibomian gland disease. This review outlines our knowledge of the histopathology, lipid abnormalities and role of microorganisms in meibomian gland dysfunction. We will also review the physiology of meibomian gland secretion and present m...
