Purpose Goblet cells in the conjunctiva secrete mucin into the tear film protecting the ocular surface. The proresolution mediator resolvin D1 (RvD1) regulates mucin secretion to maintain homeostasis during physiological conditions and in addition, actively terminates inflammation. We determined the signaling mechanisms used by RvD1 in cultured rat conjunctival goblet cells to increase intracel...

SUMMARY Dry eye disease (DED) is a multifactorial affecting tear quality and/or production and surface one of the most common disorders found in clinical practice. The association between psychiatric dry has been subject several studies since patients with this syndrome present tendency toward depressive mood. This narrative review aims to demonstrate relationship depression DED, which due side...

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...

The study of 151 patients wearing soft hydrophilic lenses for one year revealed no gross irreversible lesions with loss of vision. But of significance was the presence of superficial lesions of the corneal epithelium, and chronic stromal oedema. While no significant loss of wearing time was noted for women taking the pill, the decrease in tear secretion in those patients with a latent dry eye p...

PURPOSE Matrix metalloproteinases (MMPs) play a central role in the wound-healing process. The objective of this study was to identify and characterize the levels and molecular forms of human tear fluid collagenase-2 (MMP-8) and membrane type 1-MMP (MT1-MMP or MMP-14) in patients who had undergone excimer laser photorefractive keratectomy (PRK) and in healthy subjects. Whether MT1-MMP activates...

Recommended definition of MGD: Meibomian gland dysfunction (MGD) is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. This may result in alteration of the tear film, symptoms of eye irritation, clinically apparent inflammation, and ocular surface disease. Previous defini...

Dec 2009 were studied. Patients with vascular injuries caused by causes other than tear gas shells were excluded from the study. Results: All patients were treated with reverse saphenous vein graft as segmental loss was less than 2.5 cm. Wound infection was the most common complication, followed by graft occlu-sion. Amputation rate was 16.66%. Associated nerve injury occurred in 44.44% ...

background: artificial tears have been among the first line of therapy in management of dry eye syndrome (des). this study was conducted to compare a local artificial tear with an imported one in reduction of des. this comparison would help to evaluate the cost and benefits of each drop in the proper management of des. m aterials and methods: in this double-blind randomized clinical trial study...

One approach to the noninvasive monitoring of blood glucose concentration is to monitor glucose concentrations in tear fluid. While several methods for sensing glucose in tear fluid have been proposed, controversy remains as to the precise concentrations of tear glucose in normal and diabetic subjects and as to whether tear fluid glucose concentrations correlate with blood glucose concentration...

This study was undertaken to identify differences in the sonographic appearance of acute and chronic full-thickness rotator cuff tears. The ultrasonograms of 24 patients with an acute rotator cuff tear and 20 with a chronic tear were reviewed for tear size (width), location, and the presence and distribution of fluid. Among these 24 patients, 75% with a midsubstance tear location had an acute t...
