External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of primary acquired nasolacrimal duct obstruction (PANDO). However, new techniques such as endoscopic DCR and transcanalicular dacryocystorhinostomy (T-DCR) are being studied in an attempt to reduce surgical time, avoid external scarring and preserve the lacrimal pump while achieving the same efficacy. The purpose of this study was to compare the efficacy between conventional T-DCR and modified transcanalicular dacryocystorhinostomy (MT-DCR) in patients with PANDO...

Epiphora is a common clinical symptom of nasolacrimal duct obstruction. However, it is present in several pathologies and can lead to decreased quality of life for patients. A careful clinical examination including a detailed patient's history and diagnostic tests such as the fluorescein dye disappearance test and diagnostic syringing of the lacrimal duct are essential. Depending on the time of presentation (congenital, primary or secondary acquired), grade (subtotal or total) and location of the stenosis, different surgical approaches can be considered...

Background Tumors of the lacrimal duct are rare. Inflammatory pseudotumors do not represent neoplasias as such. Chronic inflammation may lead to an angiomatous granulation tissue. Patients The first case presents a 53-year-old male patient suffering a mass of the mediocaudal orbit after an acute dacryocystitis has been cured. Using diagnostic dacryoendoscopy, a large dacryolith was detected. Removing the concrement, via external dacryocystorhinostomy, a polypous tissue appeared which was resected as well. The second case concerns a 29-year-old female patient...

Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. We report a case of a young female who presented to us with complaints of watering and a mass lesion in the lacrimal sac region. An organized perilacrimal mass filled with thick pultaceous material was noted during surgery. Following the drainage of the mass lesion, irrigation of the lacrimal system was freely patent. Microbiological examination and DNA sequencing targeting interspacer region was suggestive of Pleurostomophora richardsiae species...

Pneumatocele of the lacrimal sac is an uncommon entity and has been rarely reported in literature. The valvular function of the Hasner's valve at the lower end of nasolacrimal duct is presumed to prevent the retrograde reflux of air into the lacrimal sac with increased intranasal pressure as in valsalva maneuver. Loss of this valvular function as noted with persistent positive airway pressure ventilation can cause retrograde air reflux into lacrimal sac. The authors report a case of lacrimal sac pneumatocele which developed following blunt nasal trauma involving the bony nasolacrimal duct...

Unresolved epiphora in childhood is one of the most frequent issues in paediatric ophthalmology. In this context, connatal nasolacrimal duct obstruction (CNLDO) is the most important differential diagnosis and the condition is caused by a persistent Hasner's membrane in most cases. As there is a risk of complications, treatment should be considered. Therapeutic options include conservative and invasive approaches. As CNLDO is associated with high spontaneous recovery rates during the first years of life, the indication for invasive interventions must be carefully deliberated in that period...

The maxillary sinus is the most common site of sinonasal inverted papilloma. Endoscopic sinus surgery, in particular endoscopic medial maxillectomy, is currently the gold standard for treatment of maxillary sinus papilloma. Although a common technique, complications such as stenosis of the lacrimal pathway and consequent development of epiphora are still possible. To avoid these problems, we propose a modification of this surgical technique that preserves the head of the inferior turbinate and the nasolacrimal duct...

The lacrimal gland (LG) is important as it has a significant role in maintaining the stability of the microenvironment of the ocular surface. When a loss of function occurs in the LG, a significant reduction in tear production and dry eye disease (DED) may occur. A mammalian LG is a secretory gland consisting of acini and ducts. The interaction between epithelial cells and mesenchymal cells plays a major role during development and the self-restoration process of the gland. Some factors, such as fibroblast growth factor 10 and bone morphogenetic protein 7, are associated with these processes...

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...

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...
