Lacrimal duct

Declan C Murphy, Mohamed Alfiky, Peter Prinsley
Oncocytomas are rare glandular tumours, typically found in salivary glands and kidneys. A 76-year-old man presented to an ophthalmology department after 3 months of persistent right-sided epiphora. Lacrimal syringing and a fluorescein dye test demonstrated an obstruction at the level of the nasolacrimal duct (NLD). Owing to the patient's history of dacryocystitis, endoscopic dacryocystorhinostomy was organised. When in theatre however, nasendoscopy identified a polypoid mass at the lateral aspect of the inferior turbinate, obstructing the right NLD opening...

Objective: To investigate the static and dynamic features of the normal lacrimal sac (LS)-nasolacrimal duct (NLD), and find out if tear flows while the subject is in supine position with eyes closed. Methods: Cross-sectional study. Healthy volunteers and patients whose head were examined by MRI in Guangdong Provincial Hospital of Integrated Traditional Chinese and Western Medicine with normal LS-NLD were recruited. The normal lacrimal ducts of the candidates were scanned, while candidates remained in supine position, by static or dynamic imaging procedures with a 1...

BACKGROUND: Dacryocystorhinostomy (DCR) is the gold standard surgical treatment for nasolacrimal duct obstruction. External DCR is the traditional approach (EXT-DCR); however, the advent of minimally invasive surgeries and the development of optic fiber and laser technologies have made it possible to perform laser transcanalicular DCR (T-DCR), a minimally invasive procedure. This study measured the fluorescein transit time (FTT) after EXT-DCR or T-DCR to evaluate the lacrimal drainage and lacrimal pump function after these two types of DCR...

Purpose: Primary ductal adenocarcinoma arising in the structures of the lacrimal apparatus is extremely rare, and the entity is considered a lacrimal counterpart of salivary duct carcinoma, of which the majority are known to express androgen receptor (AR). Less than 10 cases of AR-positive carcinomas of lacrimal gland or lacrimal sac have been described. Observations: We present a primary ductal adenocarcinoma with AR expression involving the nasolacrimal duct of a middle-aged patient who had suffered from right eyelid swelling, diplopia and epiphora for 4 months...

BACKGROUND: Canaliculitis is often misdiagnosed. There are several conservative and surgical treatment options. PATIENTS AND METHODS: Retrospective analysis of 14 canaliculotomies in 10 patients with canaliculitis. The overall length of the surgically induced opening was measured and compared to the corresponding untreated lacrimal punctae. Lacrimal duct concrements were liberated and sent for microbiological and histological analysis. Patient satisfaction and relief of symptoms were documented as well as clinical findings...

Idiopathic canine keratoconjunctivitis sicca (iKCS) is a common condition of the canine eye involving a deficiency in aqueous tear production which is commonly held to have an immune-mediated, as most probably an autoimmune aetiopathogenesis. Yet to date no direct evaluation has been made of the inflammatory cell populations in the lacrimal tissue of dogs with iKCS. Here we sought to quantify T and B lymphocyte populations in the lacrimal tissue of the nictitans glands of dogs with iKCS those with neurological KCS (nKCS)and also in dogs with tear production within the recognized normal levels and no ocular surface signs of KCS...

Acquired injuries of the nasolacrimal apparatus may be the result of craniomaxillofacial surgical procedures, facial trauma, or inflammation. Injury to the nasolacrimal duct system following maxillary orthognathic surgery is rarely reported. This study evaluated the importance of early diagnosis and treatment of epiphora developing after Le Fort I surgery. The records of 83 patients who underwent maxillary orthognathic surgery over a 2-year period were reviewed. The prevalence of postoperative epiphora was 3...

Lacrimal surgery aims to provide a low-resistance tear drainage passage. An assessment of lacrimal resistance guides decisions on surgery. We present results of a modified tear duct irrigation system that reliably measures lacrimal outflow resistance. Patients in a specialist lacrimal clinic had a full work-up to the point of tear duct syringing. The tear ducts were irrigated using a manometric system, which applied a fixed, known head of fluid pressure to a lacrimal cannula. Fluid flow is recorded and the lacrimal resistance derived as fluid pressure/fluid flow (units cmH20 secml-1, for simplicity presented as drops per minute, dpm)...

A 42-year-old Asian Indian male with a history of conjunctival melanoma in the left eye presented with a recurrent tumor in the upper tarsal conjunctiva. The tumor was completely excised under margin control, followed by two-staged eyelid reconstruction. During the second stage of the eyelid reconstruction, a brown-colored discharge was noted at the punctum, which on cytology was confirmatory of melanoma. Left dacryocystectomy with en bloc nasolacrimal duct (NLD) excision was performed. Histopathology demonstrated infiltration of the NLD by the tumor with no presence of melanoma in the lacrimal sac...

BACKGROUND: The lymphatic vascular pattern in the head of mice has rarely been studied, due to problems of sectioning and immunostaining of complex bony structures. Therefore, the association of head lymphoid tissues with the lymphatics has remained unknown although the mouse is the most often used species in immunology. RESULTS: Here, we studied the association of nasal and nasolacrimal duct lymphatics with lymphoid aggregates in 14-day-old and 2-month-old mice...

BACKGROUND: Epiphora has a significant impact on the patient's quality of life and is commonly caused by nasolacrimal duct obstruction. Dacryocystorhinostomy (DCR) has traditionally been performed via an external approach, which involves a skin incision. With the advent of endoscopes, the endonasal approach to DCR has gained significant popularity. METHOD: To prospectively compare the quality of life of adult patients who underwent either an endonasal or an external DCR for acquired nasolacrimal duct obstruction, the Lacrimal Symptom Questionnaire (Lac-Q) was administered before and after surgery...

Primary Sjögren's syndrome (pSS) is a solitary poorly understood autoimmune inflammatory disease by involvement of the salivary and lacrimal glands resulting in dry mouth and dry eyes. Myoepithelial cells (MECs) are cells knowing for its hybrid epithelial and mesenchymal phenotype that are important components of the salivary gland (SGs) structure aiding the expulsion of saliva from acinar lobules. In this study we investigate possible alteration in the myofilament component of MECs in SGs specimens obtained from pSS patients in comparison with healthy subjects, to evaluate MECs hypothetical involvement in the pathogenesis of pSS...

Background: Limited spatial nasal cavity in children, make pediatric dacryocystorhinostomy (DCR) a difficult surgical procedure. We apply a limited approach to pediatric DCR and follow them for their consequences. Materials and Methods: An experimental study was done in pediatric DCR with limited approach (age < 14-year-old). After written consent, with general anesthesia, with nasal endoscopic surgery, lacrimal bone is exposed and extruded. In contrast with routine procedure, ascending process of maxillary sinus reserve; and marsupialization and wide exposure to lacrimal sac was done only by lacrimal bone defect; and cannulation preserve with temporary silicone tube...
