Oncocytoma of the lacrimal sac is a rarely encountered clinical entity. We report the case of a 72-year-old female patient who was diagnosed to have bilateral nasolacrimal duct obstruction during a pre-cataract surgery screening. Subsequently, she underwent bilateral dacryocystectomy. Histopathological examination of the left lacrimal sac revealed a tumour composed of acini lined by oncocytic c...

Congenital absence of lacrimal puncta may be an isolated finding or associated with other developmental abnormality. Nasolacrirnal ducts can be absent thus predisposing to the formation of a congenital lacrimal mucocele. Punctal and canalicular agenesis is very rare. Four percent of new patients attending the lacrimal clinic at Moorfields Eye Hospital, London, UK. from 1981 to 1990 inclusive we...

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...

BACKGROUND:. The lacrimal gland is un-capsulated, multilobulated secretory gland situated in the lacrimal gland fossa, behind the supratemporal orbital rim. Tumor and Lesion of the lacrimal gland contain 5 to 18 % of all orbital mass. Aims and objectives: To study the incidence and prevalence of tumor of lacrimal gland. To study the clinical pattern with regard to age, incidence, gender distrib...

A case of canaliculitis with obstruction of the lacrimal canaliculus and accumulation of conglomerates is described. Pityrosporum pachydermatis was cultured from the conglomerates. To the best of our knowledge this organism has not been previously implicated in such infections. Cure was obtained by treatment with nystatin administered topically and as an irrigation of the lacrimal pathways. The...

Ocular drug delivery is the most fascinating and challenging task faced by pharmaceutical researchers. One of the major barriers of ocular medication is to obtain and maintain a therapeutic level at the site of action for prolonged periods of time. Major problems encountered by conventional ocular dosage forms include rapid pre-corneal drug loss due to naso-lacrimal drainage; tear turnover and ...

A review of endoscopic dacryocystorhinostomy (EDCR) performed in University Hospital from 1998 till early 2001 were carried out. They were reviewed for indication, functional results, complications and other associated factors. Eleven patients (6 female and 5 male) were reviewed. All had unilateral nasolacrimal duct (NLD) obstruction (6 right, 5 left). Their ages range from 6 to 73 years. All 1...
