INTRODUCTION: Dacryocystitis is an infection of lacremical sac due to obstruction of nasolacrimal duct which has primary or secondary causes. Idiopathic inflammatory obstruction is the primary cause. Trauma, infection, inflammation, neoplasia, and mechanical obstruction are secondary one. AIM: The objective of this study is determination of bacterial samples from patients with chronic acquired nasolacrimal duct obstruction. METHODS: This cross-sectional study was contained 90 patients with dacryocystitis from 2010 to 2011, in Besat hospital...

In humans, the lacrimal gland (LG) is the primary contributor to the aqueous layer of the tear film. Production of tears in insufficient quantity or of inadequate quality may lead to aqueous-deficiency dry eye (ADDE). Currently there is no cure for ADDE. The development of strategies to reliably isolate LG stem/progenitor cells from the LG tissue brings great promise for the design of cell replacement therapies for patients with ADDE. We analyzed the therapeutic potential of epithelial progenitor cells (EPCPs) isolated from adult wild-type mouse LGs by transplanting them into the LGs of TSP -1(-/-) mice, which represent a novel mouse model for ADDE...

A 28-year-old Caucasian female presented with a six-month history of epiphora of the right eye. Diagnostic lacrimal syringing revealed obstruction of the right nasolacrimal duct. During external dacryocystorhinostomy (DCR), the lacrimal sac had an unusual papillary appearance. Frozen sections suggested malignant lymphoid cells. Pathologic examination revealed extranodal NK/T-cell lymphoma, nasal type. Imaging revealed a mass lesion centered on the lacrimal sac. The authors describe the youngest Caucasian patient with a primary NK/T-cell lymphoma of the lacrimal sac, as well as the first case presenting with epiphora as the sole presenting symptom, reported in the literature...

The traditional use of the Crawford tube for lacrimal intubation during dacryocystorhinostomy (DCR) carries several drawbacks. We describe the use of the STENTube for DCR intubation and detail its advantages. Retrospective, noncomparative, interventional case series; 313 patients with nasolacrimal duct obstruction (NLDO) underwent 339 DCRs (216 external, 123 endonasal) with the STENTube from January 2007 - June 2013 by 5 surgeons (RS, QN, TS, SB, TN) across 3 institutions (SUNY Downstate Medical Center, Texas Oculoplastics Consultants, and Moorfields Eye Hospital)...

OBJECTIVE: Sjögren's syndrome (SS) is a systemic autoimmune disease that primarily affects lacrimal and salivary glands. We previously reported that FliC derived from E. coli could induce autoimmune pancreatitis-like lesions. From these results, we speculated that FliC could also induce SS-like exocrinopathy. In the present study, we investigated the effects of chronic exposure to FliC on lacrimal and salivary glands and the possibility that it might lead to an autoimmune response. METHODS: C57BL/6 mice were repeatedly injected with FliC and histological changes, serum levels of cytokine/chemokines and autoantibodies were evaluated at different time points after the final injection...

Orbital wall fracture reconstruction is usually recommended to prevent subsequent functional and esthetic complications. Mucocele development following such injuries or its management is recognized but rare sequelae. When they occur, they represent a diagnostic and management dilemma. The authors described a patient with orbital and ethmoidal mucocele. A 62-year-old female patient presented with progressive left exophthalmos 1 year following titanium mesh reconstruction of a medial orbital wall fracture. Computed tomography and magnetic resonance imaging demonstrated an encysted lesion encasing the mesh plate in the left orbit and extending into the ethmoidal sinus...

BACKGROUND: Snakes are considered to be vomerolfaction specialists. They are members of one of the most diverse groups of vertebrates, Squamata. The vomeronasal organ and the associated structures (such as the lacrimal duct, choanal groove, lamina transversalis anterior and cupola Jacobsoni) of adult lizards and snakes have received much anatomical, histological, physiological and behavioural attention. However, only limited embryological investigation into these structures, constrained to some anatomical or cellular studies and brief surveys, has been carried out thus far...

We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fungal colonization formation may be the first event before dacryocystitis and should be considered as a cause of epiphora...

We reported a 6-year-old girl with a history of left-eye epiphora since 2 years ago who was referred to our nuclear medicine center for dacryoscintigraphy imaging. The scan showed obstruction in the proximal portion of the nasolacrimal duct in the left eye. Imaging also showed patent nasolacrimal duct of the right eye. Tc pertechnetate activity was seen in the esophagus and stomach owing to swallowing of the excreted tracer in the nasal cavity. This was an unequivocal sign of patent lacrimal apparatus.

IgG4-related disease is a systemic disorder involving a spectrum of multiple indications, and various histopathological features are shared among different IgG4-related disease subtypes, which challenge diagnosis, although certain syndromes have organ-specific involvement. Among them, Mikulicz's disease affecting the salivary and lacrimal glands, distinguished by often elevated levels of serum IgG4, infiltration of IgG4(+) plasma cells into target tissues, and diffuse swelling, mass formation, or fibrosis of affected organs...

PURPOSE: Epiphora is sometimes associated with an absent or occluded lacrimal drainage punctum (or puncta). This study uses noninvasive "enhanced depth" anterior segment optical coherence tomography (OCT) to give improved characterization and understanding of absent or fully occluded puncta and the underlying canaliculus. METHODS: Anterior segment spectral domain OCT images were collected prospectively from 9 lower puncta of 6 patients with epiphora and absent or fully occluded puncta, not amenable to dilation in clinic, to see if a canaliculus was visible on OCT imaging below the occluded punctum...

Linear scleroderma is a localized variety of scleroderma characterized by fibrotic areas of the dermis involving head region without systemic features. Ocular involvement has been sparsely reported in the form of episcleritis, dry eye, and uveitis. We describe a 42-year-old man with linear scleroderma, en coup de sabre type with associated nasolacrimal duct obstruction and prolonged dacryocystitis.

Dry eye syndrome is an eye disorder affecting many people at an old age. Because dry eye syndrome is accelerated by aging, a useful approach to the prevention of this syndrome may be an intervention into the aging process. Previously, we showed that the mitochondria-targeted antioxidant SkQ1 delays manifestations of aging and inhibits the development of age-related diseases including dry eye syndrome. Nevertheless, the link between SkQ1's effects and its suppression of age-related changes in the lacrimal gland remains unclear...
