BACKGROUND It is frequently stated in the literature that there is a common canaliculus (CC) in the lacrimal drainage system in about 90% of individuals; in the remaining 10%, the upper and lower canaliculi enter the lacrimal sac separately. To our knowledge, there is no quantitative study supporting this assumption. OBJECTIVE To investigate the frequency of the CC and other anatomical types ...

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...

PURPOSE To analyze the features of lacrimal drainage system obstruction confirmed during external dacryocystorhinostomy surgeries and report the surgical outcomes. METHODS We reviewed the medical records of a total of 769 cases who underwent external dacryocystorhinostomy for primary lacrimal drainage obstruction between 2005 and 2014. Data about detailed location and extent of obstruction we...

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...

Lacrimal punctal agenesis is a rare cause of congenital epiphora and may occur in isolation or in combination with other lacrimal drainage anomalies such as pathologies of the canaliculus, lacrimal sac, and nasolacrimal duct. It rarely occurs in a familial manner. If diagnosed earlier, management of this condition may be as simple as a sharp opening or may necessitate more complex interventions...

introduction: the aim of this study was to determine which technique of uncinectomy, classical or swing door technique.  materials and methods: four hundred eighty cases of sinusitis were selected and operated for functional endoscopic sinus surgery (fess). out of these, in 240 uncinectomies classical uncinectomy was done whereas in another 240 uncinectomies swing door technique was used. initi...

Histologic changes in lacrimal glands of vitamin A-deficient (A-) and pair-fed control rats were compared. In A- lacrimal glands, secretory granules were strikingly diminished, and rough endoplasmic reticulum appeared somewhat atrophic. Nuclei of acinar cells were hyperchromatic and pleomorphic. Using alcian blue-PAS, no positive staining was present in acini of A- lacrimal glands, whereas in c...

Purpose To describe a case of immunoglobulin G4 (IgG4)-related dacyroadenitis presenting as bilateral chorioretinal folds from eyeball compression by massively enlarged lacrimal glands. Observations A 51-year-old woman with severely enlarged bilateral lacrimal glands was diagnosed as having IgG4-related dacryoadenitis. The glands strongly compressed the globes, forming chorioretinal folds res...
