Valerie A R Juniat, Saul Rajak
The treatment of midfacial tumours with radiotherapy, chemotherapy and radio-iodine can cause nasolacrimal duct fibrosis resulting in epiphora. Nasolacrimal patency can be maintained by stenting. We report our experience of prophylatic Nunchaku stent insertion in 5 patients prior to midfacial radiotherapy. Four out of 5 patients (80%) had patent nasolacrimal ducts without any symptoms of epiphora following removal of the stents. One patient was initially asymptomatic with patent nasolacrimal duct, but subsequently developed epiphora...

Between July 2014 and November 2015, we compared the curative effects and cost-effectiveness of two kinds of nasal endoscopic surgery for nasolacrimal duct obstruction (NLDO) in a single-centre, two-armed clinical trial with a 1-year follow-up. We included two groups: a recessive spherical headed silicone intubation (RSHSI) group and an endonasal dacryocystorhinostomy (En-DCR) group; both received nasal endoscopy. Patients were recruited from the Otorhinolaryngology and Ophthalmology departments. The main outcome measures were epiphora improvement (classified as cure, effective, or invalid), cost-effectiveness, visual analogue scale (VAS) intraoperative pain score, bleeding volume, operating time, hospitalisation time, total cost, and VAS postoperative epiphora score...

PURPOSE: To investigate the presence and distribution patterns of hormone receptors in the lacrimal drainage system in normal and diseased states. METHODS: The study was performed on cadaveric and clinical samples of the lacrimal drainage system. Immunohistochemical labeling was performed for assessing the presence and distribution of receptors of estrogen alpha, estrogen beta, aromatase (CYP19), testosterone, progesterone, oxytocin, prolactin, and somatostatins 1 to 5 (SSTR1, SSTR2, SSTR3, SSTR4, and SSTR5)...

Here we describe a modified preserved nasal and lacrimal mucosal flap technique in endonasal endoscopic dacryocystorhinostomy (EES-DCR) for patients with epiphora secondary to primary acquired nasolacrimal duct obstruction (PANDO) and evaluate its outcomes. Twenty-five patients with PANDO were retrospectively reviewed. Modified preserved nasal and lacrimal mucosal flap technique in EES-DCR was applied in all 27 eyes of 25 patients. The patients were evaluated with objective (anatomical patency) and subjective (symptomatic cure) success rates within the duration of follow-up...

We established a chronic dacryocystitis model by injecting of 0.05, 0.1, and 0.15 ml self-curing resin via the lacrimal punctum in rabbits. Animals were randomized into four groups (n = 11 animals/group). The control group received 0.15 ml normal saline. Within three months postinjection, epiphora and eye discharge were observed. At the 90th day postlacrimal passage irrigation, CT dacryocystography was performed to find changes in the lacrimal image, and hematoxylin and eosin staining was made to identify pathological changes of the lacrimal sac...

BACKGROUND: Congenital nasolacrimal duct obstruction (NLDO) is a common condition causing excessive tearing in the first year of life. Infants present with excessive tearing or mucoid discharge from the eyes due to blockage of the nasolacrimal duct system, which can result in maceration of the skin of the eyelids and local infections, such as conjunctivitis, that may require antibiotics. The incidence of nasolacrimal duct obstruction in early childhood ranges from 5% to 20% and often resolves without surgery...

This article evaluates retaining bicanalicular silicone nasolacrimal tube in patients susceptible to restenosis after punctoplasty. Sixty-nine eyes (38 patients) suffering from epiphora due to stenosis or occlusion of both punctae were included in this prospective study. All had 3 snip punctoplasty and bicanalicular silicone nasolacrimal duct insertion. Cases associated with proximal canalicular stenosis or obstructions were excluded. Tolerance to tube presence until the time of loss or removal was evaluated using a score (0 to 2)...

PURPOSE OF REVIEW: To provide a concise review of the oculoplastic manifestations of ocular graft versus host disease (GVHD), and to discuss their management. RECENT FINDINGS: Ocular GVHD occurs as a common immune-mediated complication of hematopoietic stem cell transplantation that presents as a Stevens-Johnson-like syndrome in the acute phase or a Sjögren-like syndrome in the chronic phase. Cicatricial conjunctivitis may be underreported in ocular GVHD. The spectrum of oculoplastic manifestations includes GVHD of the skin, cicatricial entropion, nasolacrimal duct obstruction, and lacrimal gland dysfunction...

Metal-mediated interlocking rings won the 2016 Nobel Prize in Chemistry. The metal-directed interlocking rings in macromolecular systems (e.g., proteins) may be similar to the form of Maxwell's electromagnetic waves; the metal ions may shuttle among the rings in the special environment. To verify this hypothesis, we designed a general approach to synthesize the multicolored gold nanoparticles (GNPs) mediated by Au(I)-directed interlocking rings in proteins. The Au(I) ions shuttled among these interlocking rings in the strong alkaline solution...

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...

BACKGROUND: Pediatric nasolacrimal duct obstruction (PNDO) requires therapeutic intervention after conservative procedures failed. As resilient treatment guidelines for the treatment are missing, the aim of this study was to evaluate the advantages of two different intervention techniques in children with PNDO. METHODS: Between January, 2006 and June, 2014, 233 children (0-208 months) were treated either with conventional probing by ophthalmologists only (Group I) or with endonasal endoscopic interdisciplinary approach (Group II)...

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...

Acquired nasolacrimal duct obstruction (NLO) causes symptoms of epiphora which can be associated with stickiness, dacryocystitis and interference with tear film causing visual blurring [1]. The annual incidence rate of NLO is 20 per 100,000, with the majority of patients being females above the age of 66 years [2]. While the aetiology is usually unknown, the site of obstruction is more commonly distal and invariably amenable to treatment by DCR surgery [3-4]. Proximal NLO at the level of the cancaliculi is less common but may still be treatable by extended DCR techniques including canalulostomy...

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...
