Abstract
Purpose: To evaluate the results of nasolacrimal polyurethane stent implantations for the treatment of primary acquired nasolacrimal duct obstruction, and to determine the effects of various surgical procedures, including stent removal, in subsequent nasolacrimal duct obstruction. Methods: This study included 15 patients who had nasolacrimal polyurethane implantations for the treatment of primary acquired nasolacrimal duct obstruction. Occluded stents were removed either by nasal endoscopy or during dacryocystorhinostomy (DCR). Cultures and biopsies were performed on the removed stents, and the results of the secondary DCR were analyzed for a 6-month follow-up period. Results: During stent removal surgery, various degrees of chronic inflammatory reaction and fibrous tissue formation were detected in the lacrimal sac and nasolacrimal duct. Formations of granuloma and fibrous tissue were found in 15 eyes, and culture-positive reaction were found in nine of the 15 eyes. Conventional dacryocystorhinostomy surgery was performed in nine of the 15 eyes and a silicone tube was located at the canaliculi. Subjective and objective outcome were favorable in 13 of the 15 eyes. Conclusions: The success rate of nasolacrimal polyurethane stent implantation for the treatment of primary acquired nasolacrimal duct obstruction is low. This may result from a chronic inflammatroy reaction. Despite the low success rate of nasolacrimal polyurethane stent implantation, the success rate of endonasal DCR as a subsequent surgery is favorable.

Abstract AIM: To assess the efficacy of the temporary placement of polyurethane nasolacrimal stents as a treatment for complete post-saccal obstruction of the lacrimal apparatus. MATERIALS AND METHODS: Polyurethane nasolacrimal stents were inserted under radiological guidance in nine patients with grade IV epiphora due to complete obstruction of the lacrimal system, at the junction of the lacrimal sac and duct (eight patients) or in the lacrimal duct (one patient). On average, the stents were re...

OBJECTIVE. The purpose of this study was to evaluate the long-term efficacy of polyurethane stent placement in adults with nasolacrimal duct obstruction.SUBJECTS AND METHODS. Polyurethane stents were placed under fluoroscopic guidance in 52 eyes of 49 patients (mean age, 43 years) with severe epiphora due to idiopathic nasolacrimal duct obstruction. The obstruction was complete in 44 eyes and partial in eight. Clinical success was defined as complete resolution of or great improvement in the sym...

PURPOSE To evaluate long-term effectiveness of a polyurethane stent in lacrimal system treatment. MATERIALS AND METHODS Fluoroscopically guided placement of a polyurethane lacrimal stent was evaluated in 727 obstructed lacrimal systems in 588 patients with a mean follow-up period of 77 weeks (range, 1鈥277 wk), from which the technical and initial success rates and long-term patency were calculated. The impact of factors affecting long-term patency, including symptom duration, previous probing, p...

PURPOSE To evaluate in a prospective multicenter setting the clinical utility of polyurethane stents in the percutaneous management of epiphora. MATERIALS AND METHODS Patients ( N = 163; age range=22鈥85 y, mean=52 y; 29 men, 134 women) with severe epiphora had stents ( n = 183) inserted under fluoroscopic guidance in 180 lacrimal systems (unilateral = 146; bilateral=17) to treat complete ( n = 172) or partial ( n = 8) obstruction of the nasolacrimal duct or sac.

PURPOSE: To determine the efficacy of dacryocystoplasty with balloon dilation in the treatment of acquired obstruction of the nasolacrimal system in adults. METHODS: Balloon dacryocystoplasty was performed in 52 eyes of 42 patients under general anaesthetic. A Teflon-coated guidewire was introduced through the canaliculus and manipulated through the nasolacrimal system and out of the nasal aperture.

To investigate characteristics of biofilm which is usually found in silicone tube for nasolacrimal duct surgery and can be the root of chronic bacterial infections eventually resulted in surgical failure. To form a biofilm, sterile silicone tube was placed in culture media of Staphylococcus aureus, Corynebacterium matruchotii, Pseudomonas aeruginosa, or Streptococcus pneumonia. Biofilms formed on these silicone tubes were fixed with 95% ethanol and stained with 0.1% crystal violet. After stainin...

Summary The Heidelberg Retina Tomograph is a confocal scanning laser system. Using different modules it enables acquisition and analysis of the three-dimensional images of the anterior and posterior segment of the eye. Tomography is an expensive diagnostic method, it can not and should not replace the slit lamp examination, which gives the ophthalmologist an essential wide view of intraocular structures. Quantitative evaluation of all relevant anatomical structures, comprehensive data for glauco...
