INTRODUCTION: Congenital nasolacrimal duct obstruction (CNLDO) is the most common cause of epiphora in infancy. Spontaneous resolution occurs in the majority of the cases by 1 year of age. Nevertheless, obstruction has a negative impact on the outcome of conservative or surgical therapy, especially in cases of complex CNLDO. When the condition persists beyond several months, early intervention with dacryoendoscopy (DE) around the age of 1 year could yield good results. The objective of the study is to analyze the success rate and effectiveness of early DE for complex CNLDO in the first year of life...

BACKGROUND: One of the most frequent issues in pediatric ophthalmology concerns congenital nasolacrimal duct obstruction (CNLDO). Typically, irritation of the medial eyelid angle occurs during the first days of life and later increased epiphora appears as tear production is still reduced in young infants. In the case of intrasaccal or postsaccal nasolacrimal duct stenosis, a chronic dacryocystitis develops. METHODS: Modern minimally invasive diagnostics and therapy of CNLDO are reviewed by means of a search of the recent literature and reflection of own experiences...

PurposeTo assess the influence of dacryoscintillography (DSG) on the treatment decision for patients with epiphora and clinically patent non-functioning lacrimal systems.MethodsA retrospective 3-year review. Inclusion: patients having DSG for epiphora with delayed tear clearance, lacrimal system patency on syringing, and no visible external cause for watering. On the basis of regurgitation during syringing, tear ducts were divided into freely patent (FP≤20%) or stenosed. The DSG results were examined for correlation with symptoms and clinical examination, the influence on decision to proceed to dacryocystorhinostomy (DCR), and the ability to predict the surgical outcome...

REVIEW
Lona Jawaheer, Caroline J MacEwen, Deepa Anijeet
BACKGROUND: A dacryocystorhinostomy (DCR) procedure aims to restore drainage of tears by bypassing a blockage in the nasolacrimal duct, through the creation of a bony ostium that allows communication between the lacrimal sac and the nasal cavity. It can be performed using endonasal or external approaches. The comparative success rates of these two approaches have not yet been established and this review aims to evaluate the relevant up-to-date research. OBJECTIVES: The primary aim of this review is to compare the success rates of endonasal DCR with that of external DCR...

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.
