in this study ten pairs of superior gland of third eyelid of 10 adult male camels free of apparent ocular disease were examined to compare the normal anatomical and histological properties of these glands. after dissecting, all of the glands were characterized and measured (length and width) on both the left and right side. in the camels, the superior gland of the third eyelid was oval shaped a...

in this research, morphology and histology of the left and right lacrimal glands of ten adult ostrich were carefully studied. after the topographical study of the glands and measuring the dimension of them, tissue sections were prepared and stained by current histology. results revealed that in ostrich, lacrimal gland was dark brown to black color and was located obliquely in dorsolateral part ...

PURPOSE To evaluate the effect of corneal epithelial wounding on lacrimal gland expression of hepatocyte growth factor (HGF), keratinocyte growth factor (KGF), and epidermal growth factor (EGF) in the rabbit model. METHODS Rabbits had corneal epithelial scrape injuries, and the lacrimal gland was removed at different times after wounding. HGF, KGF, and EGF mRNA expression was examined by quan...

Purpose Although normal function of the lacrimal gland is essential for vision (and thus for human well-being), the lacrimal gland remains rather poorly understood at a molecular level. The purpose of this study was to identify new genes and signaling cascades involved in lacrimal gland development. Methods To identify these genes, we used microarray analysis to compare the gene expression pr...

A variety of proteins have been identified in tears, which are composed of secretions from all the orbital glands. It has been assumed that the lacrimal gland was the source of these proteins because there is indirect evidence that the lacrimal gland can secrete protein in response to cholinergic stimulation. In the present study, the concentration of protein was determined in lacrimal gland fl...

PURPOSE OF REVIEW The goal of this article is to offer an update on the treatment and prognosis of the most common epithelial tumors of the lacrimal gland, report on new pathological entities and offer a review of the classification of lacrimal gland tumors. RECENT FINDINGS Improvements have been made in the understanding of lacrimal gland lesions with the knowledge that lacrimal gland tumors...

In order to determine the source of the retinol which has been identified in the tear fluid, the lacrimal gland ducts of rabbits and rats were cannulated and the collected lacrimal gland fluid was analyzed by high performance liquid chromatography. Retinol was identified in the lacrimal gland fluid of rabbits and rats, and it is concluded that the lacrimal gland is the source of retinol in the ...

PURPOSE. The lacrimal gland secretes water, electrolytes, and protein into the tear film. Decreased secretion from the lacrimal gland can lead to dry eye syndromes with deleterious effects on vision. Protein kinase C (PKC)plays a major role in cholinergicand 1-adrenergic–induced protein secretion from the lacrimal gland. This study was undertaken to determine whether activation of PKC alone wou...

Ectopic lacrimal gland tissue is rarely found within the eye. The first report was that of Puech (i 887) who described an adenoma of the choroid in an adult female. The lesion had the appearance of lacrimal gland tissue which was adherent to the sclera and the retina. After an interval of 65 years Christensen and Anderson (I 952) described ectopic lacrimal gland tissue within the sclera, ciliar...

The lacrimal gland plays an important role in maintaining a homeostatic environment for healthy ocular surfaces via tear secretion. Dry eye disease, which is caused by lacrimal gland dysfunction, is one of the most prevalent eye disorders and causes ocular discomfort, significant visual disturbances, and a reduced quality of life. Current therapies for dry eye disease, including artificial tear...
