Structural and functional characteristics of meibomian glands in meibomian gland dysfunction
… techniques to investigate novel aspects of meibomian gland (MG) morphology; to evaluate meibum composition and ocular surface signs and symptoms associated with morphological changes in the glands before and after treatment for Meibomian gland dysfunction (MGD). Methods: There were five …

Imaging of Meibomian Glands in Various Species
Purpose: Meibomian glands (MG) secrete meibum, the lipid component of the tear film essential for tear stability which is disrupted during dry eye disease. Blink rate varies across species suggesting differences in tear film stability, MG anatomy, and meibum quality. Meibography is performed on …

The Role of Hyaluronan in the Ocular Surface
… extracellular matrices of the corneal limbus and meibomian gland (MG). This dissertation evaluated the role of hyaluronan in ocular tissues, particularly in the limbal stem cell niche and the meibomian gland. Methods: (1) To determine the role of HA in the limbal stem cell niche, primary human …

Intense Pulsed Light for the Treatment of Evaporative Dry Eye
Background Meibomian gland dysfunction (MGD) is a major aetiological factor in the development of evaporative dry eye (EDE), a common presentation in ophthalmic clinics which causes significant detrimental effects on quality of life. Traditional management strategies often fail to provide …

The eyelid and its role in contact lens discomfort
… at orifices and acini secretion reflectivity of meibomian glands, tear lipid layer thickness and tear evaporation were found to worsen with increased symptoms of discomfort, and an equation was developed to predict symptoms in lens wear. Symptomatic contact lens wearers had a significantly higher …

Role of Krox20 Transcription Factor and Krox20+ Stem Cells in Epithelial Tissue Development and Homeostasis
… the ocular surface, resulting from the loss of Meibomian glands (MGs). Expression analyses showed that Krox20-expressing cells constitute stem/progenitor cells that are restricted to the ductal region of the MG, but differentiate to give rise to the entire MG structure. Overall, this study …

Tear film structure of the contact lens wearer
… lipid layers are described. The manner by which Meibomian 91 and secret i on occurs and performs its role in the tear film is illustrated and analysed. Forced gland secretion by pressure induced localised lipid thickness increase. Eyelid closure was seen to compress the lipid film and …
