Dacryocystitis is an infection of the lacrimal sac that is usually caused by obstruction of the nasolacrimal duct. We describe a case of iatrogenic dacryocystitis that occurred secondary to the presence of an impacted piece of a metallic dilator in the lacrimal apparatus. The foreign body was detected on dacryocystography and removed during dacryocystorhinostomy. The patient recovered uneventfully.

Abstract Purpose: morphological assessment of the lacrimal ducts at various anatomical levels in patients with primary (PANDO) and secondary (SALDO) obstruction after radioactive iodine therapy.Methods. The material was obtained during endoscopic dacryocystorinostomy with revision of Hasner's valve in patients with PANDO (n=7) in the distal segments of the nasolacrimal duct and in patients with SALDO (n=7) after radioactive iodine therapy. During the surgery, a biopsy of Hasner's valve, as well as a biopsy of the lacrimal sac wall were performed. The resulting material was stained with hemotoxylin and eosin, alcyan blue and by Masson method. Morphological and morphometric analyses were performed in semi-automatic mode. The results of histochemical staining of sections were translated into points taking into account the area and optical density (chromogenicity) in relative units: 1 – weak (0 – 0.3); 2 – moderate (0.3 – 0.6); 3 – significant (>0.6). The nonparametric Mann-Whitney criterion was used for statistical analysis. The differences were considered significant at p<0.05.Results. The comparative morphological study both confirmed the available information concerning the radiation nature of the obstruction and allowed to quantify the fibrosis level of the stromal component and other lacrimal ducts structures.Conclusion. It was shown that the nasolacrimal duct sclerosis is significantly lower (p=0.029) in patients with SALDO than in patients with PANDO while fibrosis in the lacrimal sac is the same in patients of the compared groups.

A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a lacrimal sac biopsy was taken. Histopathology revealed florid chronic inflammation, with abundant granular brown pigment and polarisable crystals suggestive of an exogenous material in the lacrimal sac mucosa compatible with mascara. After initial improvement, her epiphora has recurred 1-year postoperatively, but her ocular discharge has resolved. Mascara-induced conjunctival pigmentation is well established. However, there are very few published reports of nasolacrimal duct obstruction due to mascara. Since cosmetic application of mascara and kohl eyeliner is widespread, patients and practitioners should be aware of their potential to migrate into the lacrimal apparatus and cause chronic inflammation with secondary nasolacrimal duct obstruction.

Abstract BACKGROUND. Endoscopic dacryocystorhinostomy is known to be the ideal treatment for saccal and postsaccal stenosis of the lacrimal apparatus. Following this surgery, an important inconvenient would be the stenosis of the created ostium with consecutive epiphora. MATERIAL AND METHODS. 20 patients with chronic unilateral lacrimal duct obstruction were operated in “Prof. Dr. D. Hociota” Institute of Phono-Audiology and Functional ENT Surgery, Department I, between January 2015 and July 2015. After creating the dacryocystorhinostoma, a stent was inserted transnasally to the bottom edge of the lacrimal sac and positioned to the bony margin of the ostium. Stents used varied in size from 1 to 3 mm in diameter. We followed-up our patients at 2 weeks and 1, 3, 6 months, assessing the symptoms of the lacrimal apparatus, especially the epiphora. RESULTS. The mean age of patients varied between 31 and 65. Most of our patients were women (n=14). In a total number of 16 patients epiphora disappeared, it decreased in 2 patients, and persisted in 2 patients. There were two patients with no changes who have spontaneously eliminated the stent 2 or 3 days after the surgery. The most widely used stent size was 3 mm diameter, with a success rate of 90%. CONCLUSION. The endoscopic approach may be an effective procedure in patients with pathologies of the lacrimal apparatus. In order to achieve an efficient result, both a preoperative rigorous preparation and also postoperative medical care are necessary. In conclusion, ostium stenting represents a better way to ensure a longer period of maintaining the permeability of the lacrimal apparatus.

Purpose To study the functional metagenomic profile of the microbes isolated from the lacrimal sac of patients with primary acquired nasolacrimal duct obstruction. Methods A prospective study was performed on 10 consecutive lacrimal sac samples obtained for the metagenomic analysis from patients with primary acquired nasolacrimal duct obstruction ( who underwent endoscopic dacryocystorhinostomy at a tertiary care Dacryology service. The samples were collected intraoperatively soon after a full-length lacrimal sac marsupialization and immediately transported on ice to the laboratory. Following DNA extraction and library preparation, a whole shotgun metagenome sequencing was performed on the Illumina NOVASEQ 6000TM platform. The downstream processing and bioinformatics of the samples were performed using multiple software packaged in SqueezeMetaTM pipeline and functional analysis using the MG-RASTTM pipeline. Results The microbial gene mapping and protein prediction demonstrated proteins with known functions to range from 66.41% to 84.03% across the samples. The functional category distribution of Kyoto Encyclopedia of Genes and Genomes ortholog (level 1 data) showed metabolism to be the most commonly involved function followed by environmental information processes, genetic information processes and cellular processes. The functional subsystem profiling demonstrated genes associated with carbohydrate, protein and RNA metabolism, Amino acids and their derivatives, cofactors and prosthetic groups and factors involved in cell structure regulation and cell cycle control. Conclusion This is the first functional metagenomic profile of the lacrimal sac microbiota from patients with primary acquired nasolacrimal duct obstruction. Functional analysis has provided newer insights into the ecosystem dynamics and strategies of microbial communities inhabiting the lacrimal sac. Further Lacriome studies may provide clues for better understanding of the disease etiopathogenesis.
