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...

PURPOSE: The aim of the study was to assess practice patterns on the use of intraoperative Mitomycin-C (MMC) and lacrimal stents (intubation) in dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction (NLDO) among oculoplastic surgeons in India. The survey was aimed at obtaining data on the duration of stent placement and specifics regarding MMC usage namely, concentration and duration of application. METHODS: A survey that included questions on the management of lacrimal disorders was sent in April 2015 to members of the Oculoplastic Association of India, through an email communication...

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.

PURPOSE: The aims of this study were to report the preliminary experience of using telescopes, which were enabled for navigation guidance, and their utility in complex endoscopic lacrimal surgeries. METHODS: Navigation enabling of the telescope was achieved by using the AxiEM™ malleable neuronavigation shunt stylet. Image-guided dacryolocalization was performed in five patients using the intraoperative image-guided StealthStation™ system in the electromagnetic mode...

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...

Several minimally invasive modifications of endoscopic medial maxillectomy have been proposed recently, with the least traumatic techniques utilizing the lacrimal recess as a route to enter the sinus. The aim of the study was to analyze the anatomy of medial maxillary wall in the region of nasolacrimal canal and, thus, to determine the capability of performing minimally invasive approach to the maxillary sinus leading through the lacrimal recess. The course of nasolacrimal canal and the distance between the anterior maxillary wall and the nasolacrimal canal (the width of lacrimal recess) were evaluated in 125 randomly selected computed tomography (CT) head examinations...

BACKGROUND: IgG4-related disease is a rare, clinical and pathologic disease entity of unknown etiology. Its main features are increased serum concentrations of IgG4 > 1,35 g/l, lymphocyte and IgG4+plasma-cell infiltration within tissues, fibrosis or sclerosis. The classical presentation of IgG4-RSD is pancreatitis which is combined with the involvement of biliary ducts in 74 percent of patients. Extrapancreatic manifestations include: abdominal or mediastinal lymphadenopathy; the involvement of salivary glands and lacrimal glands, kidneys, lung, retroperitoneum...

Background: To explore the prevalence of lacrimal duct obstruction in patients with infectious keratitis, and the necessity of lacrimal duct dredge in the treatment of human infectious keratitis. Methodology/Principle Findings: The design is prospective, non-control case series. Thirty-one eyes from twenty-eight continuous patients with infectious keratitis were included in this study. The presence/absence of lacrimal duct obstruction was determined by the lacrimal duct irrigation test. The diagnosis of infectious keratitis was made based on clinical manifestations, cornea scraping microscopic examination and bacterial/fungus culture...

The main purpose of this paper is to provide the information about the incidence and types of pathology of secondary acquired obstructions of the lacrimal excretory outflow system caused by primary lacrimal sac non-neoplastic and neoplastic lesions. After a thorough literature search, 17 case-control studies were found and selected, data were extracted and categorized, to evaluate specific lacrimal sac pathology mimicking inflammation. A total of 3865 histopathologically examined lacrimal sac wall biopsy specimens from 3662 patients, taken during dacryocystorhinostomy for clinically presumed primary chronic dacryocystitis, were analyzed...

PURPOSE: To examine the surgical outcome of three-flap external dacryocystorhinostomy (3-flap ex-DCR) based on the most common site of granulation occurrence in no-flap endonasal DCR (no-flap en-DCR). METHODS: This was a retrospective observational study. We first examined the location of granulation occurrence in the osteotomy site using nasal endoscopy after no-flap en-DCR on 53 sides of 37 patients (5 male, 32 female) with nasolacrimal duct obstruction. Based on the results of this surgery, we performed 3-flap ex-DCR on 70 sides of 61 patients (18 male, 43 female) with nasolacrimal duct obstruction...

INTRODUCTION: The formation of a fistula between the lacrimal sac and the skin is a classic outcome of resistant lacrimal sac abscesses. There is currently no consensus about treatment in such cases. The goal of this study was to describe the natural history of acquired fistulas between the lacrimal sac and the skin, occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula. MATERIALS AND METHODS: This prospective study was only descriptive and included patients between 1999 and 2012...

Patients with conjunctival cicatrizing disease may develop lacrimal obstruction. Little is published on lacrimal obstruction as the presenting feature of otherwise asymptomatic cicatrizing conjunctival disease. The records of all patients presenting between 1994 and 2015 with lacrimal obstruction found to have cicatrizing conjunctival disease were reviewed. Demographic details, clinical findings, disease progression and treatment were analyzed. Thirty-five patients (25 female), aged 43-91 years (median 74, mean 71...
