Dacryocystitis Secondary to Orbital Mesh Implant Impingement: A Rare Etiology.

A 22-year-old male patient reported swelling in relation to the right eye and developed recurrent purulent discharge and epiphora following a reconstructive traumatic orbital floor fracture repair two years ago. Radiographic investigation and surgical exploration reveal obstruction of the lacrimal apparatus at the lacrimal sac level due to over-extension/migration of the orbital floor mesh. The migration of the mesh was probably due to the extension of the mesh medially into the paranasal region.

Chronic dacryocystitis: An insight into bacteriology and antimicrobial sensitivity pattern.

CONTEXT: Adequate management of chronic dacryocystitis is an essential prerequisite before any intraocular surgery owing to a grave risk of endophthalmitis. The knowledge of bacteriology of chronic dacryocystitis would accentuate the choice of effective antimicrobial agents and thus help in reducing the irrational use of antimicrobial agents and subsequent development of drug resistance. AIMS: We aimed to identify the causative bacterial flora and study the antimicrobial sensitivity and resistance pattern in cases of chronic dacryocystitis. SETTINGS AND DESIGN: This was a cross-sectional observational study. SUBJECTS AND METHODS: Conjunctival swabs were obtained from both eyes from 102 patients with clinical evidence of chronic dacryocystitis. Specimens for microbiological analysis were obtained, either from the conjunctival cul-de-sac and everted puncta by applying pressure over the lacrimal sac area or from the refluxing material after irrigating the lacrimal sac with sterile saline. The specimens were sent for culture and sensitivity in the department of microbiology. Ethical approvals were duly obtained. STATISTICAL ANALYSIS USED: Percentage assessment was used for statistical analysis. RESULTS: The cultures showed the presence of Staphylococcus aureus in 50% of bacterial isolates obtained from the involved eyes, followed by coagulase-negative Staphylococcus in 11.53% of isolates and Enterococcus also in 11.53% of isolates. It was observed that cefoxitin was the most sensitive antibiotic against Gram-positive organisms, followed by vancomycin and clindamycin, whereas maximum resistance was seen for penicillin and ofloxacin. For Gram-negative organisms, imipenem was found to be most sensitive, followed by gentamicin and co-amoxiclav, whereas maximum resistance was seen for ciprofloxacin. CONCLUSIONS: It was concluded that Gram-positive bacteria predominantly S. aureus was the most commonly isolated bacteria in cases of chronic dacryocystitis as compared to Gram-negative bacteria and cefoxitin was found to be the overall most effective antibiotic for Gram-positive bacteria.

Acute dacryocystitis secondary to Burkholderia cepacia and Sphingomonas paucimobilis mixed infection: A novel case report.

Acute dacryocystitis caused by Burkholderia Cepacia and Sphingomonas Paucimobilis is uncommon. To the best of our knowledge, presence of mixed pathogens Burkholderia Cepacia and Sphingomonas Paucimobilis causing acute dacryocystitis in immunocompetent patients never been described. Burkholderia Cepacia and Sphingomonas Paucimobilis been reported only as a single microorganism causing other ocular infections in immunocompromised patients. Middle age, medically free female patient, presented to the emergency department at our hospital, with a history of nasolacrimal duct obstruct (NLDO) complaining of inferior preocular swelling associated with localized pain diagnosed as acute dacryocystitis. She was on oral Amoxicillin/clavulanic acid, oral Nitroimidazole antimicrobial and topical Tobramycin from elsewhere. However, no improvement had been noticed. We kept the patient on the same medications and swaps taken for culture and sensitivity. Patient presented to the first follow-up appointment with no improvement on her status. Culture and sensitivity revealed 2 pathogens: Burkholderia Cepacia and Sphingomonas Paucimobilis. We have changed the antibiotic to oral Trimethoprim/ Sulfamethoxazole as it showed positive sensitivity to the pathogens based on the sensitivity chart. Second follow-up appointment patient's condition improved.

Primary diffuse large B-cell lymphoma of the lacrimal sac with involvement of maxillary sinus: a case report and review of literature.

Primary lacrimal sac lymphoma is a rare condition, often presenting with nasolacrimal duct obstruction. Herein, we present a unique case of diffuse large B-cell lymphoma (DLBCL) involving the lacrimal sac, maxillary sinus, and infraorbital nerve. Prompt diagnosis via biopsy is essential for timely treatment and the prevention of tumor progression. A 66-year-old female presented with intractable epiphora, infraorbital nerve hypesthesia, and medial canthal swelling. Imaging revealed a soft tissue mass in the right maxillary sinus extending into the right inferior orbit and nasal cavity. A biopsy confirmed DLBCL, prompting systemic chemotherapy. Residual disease prompted high-dose involved-site radiation, resulting in tumor regression. To our knowledge, this is the first case of primary DLBCL of the lacrimal sac with concurrent involvement of the maxillary sinus and infraorbital nerve. This case underscores the significance of lacrimal sac biopsy in refractory dacryocystitis or unilateral sinus disease and the effectiveness of multimodal treatment approaches in managing DLBCL.

Computed Tomography Signs of Sinonasal Inflammation in Patients with Acute Dacryocystitis.

BACKGROUND: Nasal and paranasal sinus abnormalities may be related to nasolacrimal duct obstructive disease but are strongly debated. Data of acute disease stage are lacking. OBJECTIVE: The purpose of this study was to determine if there are correlations between radiologic signs of sinus inflammation and acute dacryocystitis (AD). METHODS: This cross-sectional controlled study was conducted at Wenzhou, Zhejiang Province, China from February 2021 to November 2023. Forty-four consecutive patients with AD and 50 consecutive patients with orbital tumors (the control group), who completed preoperative computed tomography scans, were enrolled to evaluate the extent of their inflammatory sinonasal disease by the modified Lund-Mackay score system. RESULTS: The inflammation signs of the paranasal sinuses (total mean sinus scores, 95% CI [0.00, 2.00]; P < 0.001), namely the anterior ethmoid sinus(95% CI [0.00, 1.00]; P < 0.001), the posterior ethmoid sinus(95% CI [0.00, 0.00]; P = 0.003), the frontal sinus (95% CI [0.00, 0.00]; P = 0.02), and the ostiomeatal complex (P < 0.001) were more extensive in patients with AD when compared with the controls. The disease course was negatively correlated with the anterior ethmoid (P = 0.03) and frontal scores (P = 0.01). The symptom of eyelid swelling was positively correlated with the anterior ethmoid (P = 0.03), ostiomeatal complex (P = 0.004), and total sinus scores (P = 0.005). CONCLUSION: Inflammatory sinus disease was found to be more frequent in patients with AD, which was gradually alleviated with the prolongation of the disease course. The mutual spread of inflammation particularly in the acute course may play an important role in lacrimal duct obstructive disease.

Lacrimal sac Aspergillosis Masquerading as Malignancy: A Rare Case Report.

Invasive fungal infections are uncommon in an immunocompetent host and pose a real diagnostic dilemma. As they have a propensity for locoregional destruction, clinic-radiological findings can mislead to a faulty diagnosis of a malignancy. Here we present a case of Primary Aspergillus dacryocystitis in an immunocompetent individual initially thought to be an orbital malignancy until the histopathological examination.

Microbiology of acute bacterial dacryocystitis: a tertiary institutional experience in South Australia.

PURPOSE: To provide a comprehensive microbiological profile of bacterial dacryocystitis in South Australia. By identifying the specific microorganism and antibiotic susceptibility, this study intends to aid ophthalmologists in choosing appropriate empirical antibiotic therapies and development of evidence-based clinical guidelines. METHOD: A retrospective study was conducted at the Royal Adelaide Hospital (RAH) over five years (2018-2023) of patients with acute dacryocystitis. The study included 43 patients, and data encompassed demographic information, clinical presentation, microbiological analysis, management, and outcomes. Patients with chronic dacryocystitis were excluded. RESULTS: Among the 43 patients included in the study (female 28 (65%), mean age: 64 years old), the most common clinical features were pain (74%) and swelling (70%). Organisms were identified in 49% of patients, with the predominant bacteria being Staphylococcus aureus (42%), Streptococcus species (19%), and Escherichia coli (8%). Aggregatibacter species (8%), Morganella morganii (4%), Enterobacter cloaceae (4%), Hafnia alvei (4%), mixed anaerobes (4%), E coliforms (4%) and Pseudomonas aeruginosa (4%) were also identified. The most frequently prescribed empirical antibiotics were amoxicillin-clavulanic acid (50%), flucloxacillin (33%) and cefalexin (18%). CONCLUSION: The microbiological trends of acute dacryocystitis have largely remained consistent, with a predominance of Gram positive organisms. This is the most recent profile analysis of acute dacryocystitis in South Australia and will help form evidence-based clinical guidelines.

Langerhans cell histiocytosis mimicking acute dacryocystitis.

Langerhans cell histiocytosis (LCH) is a myeloid neoplasm characterized by clonal neoplastic proliferation of Langerhans-type dendritic cells associated with an inflammatory infiltrate predominantly composed of lymphocytes and eosinophils. In this article, we present an unusual case of LCH with significant swelling in the left lacrimal sac region in a 3-year-old child, clinically mimicking acute dacryocystitis. Microscopically, it showed intense inflammatory infiltrate and histiocytes with irregular nuclei. The tumor cells were positive for S-100 protein, CD1a, and CD207 (langerin). Molecular study was positive for the V600E/E2/D mutation (EXON 15). This case emphasizes the importance of careful clinical, radiographic, and microscopic evaluation, as some neoplasms may mimic common benign lesions.

Dacryocystitis in a Patent Nasolacrimal Drainage System: A Literature Review.

INTRODUCTION: Acute dacryocystitis is an acute infection and the lacrimal sac secondary to pathogenic microorganism growth within the stagnant fluid in the lacrimal sac secondary to nasolacrimal duct obstruction. METHODS: A literature review was conducted on the PubMed database using the following search terms "dacryocystic retention" and "dacryocystitis" or "dacryolith" or "lacrimal duct" or "pseudo-dacryocystitis". RESULTS: The literature review suggests that dacryocystitis in a patent nasolacrimal drainage system can stem from diverse causes including the mechanical impaction by dacryoliths, viral infections and anatomical variations. It is believed that these causes lead to transient obstruction to the nasolacrimal excretory system predisposing to secondary infections. Idiopathic temporary dacryocystic retention is also highlighted in this review. CONCLUSIONS: This review broadens the understanding of dacryocystic retention and highlights the need for careful diagnosis and tailored treatment plans, particularly in cases deviating from the traditional etiological pathways.

External dacryocystorhinostomy: A critical overview of the current evidence.

PURPOSE: External dacryocystorhinostomy (ext-DCR) is still considered the gold standard in the treatment of distal lacrimal duct obstruction. Despite an overall high success rate, some patients do relapse after surgery and the ideal perioperative management has not been identified yet. The purpose of this study is to critically discuss the published evidence in the last five years on the medical and surgical management of external dacryocystorhinostomy. Furthermore, the drawbacks of the available literature and the perspectives in this field will be also highlighted. METHODS: Systematic review of the literature in the last 5 years by using PubMed and Google Scholar. RESULTS: A total of 64 articles were included. Many technical modifications and surgical refinements have been proposed but a formal comparison among the various techniques is hampered by methodological heterogeneity. The use of local anesthesia, and the perioperative adjunctive techniques to reduce the risk of restenosis are also gaining popularity but the level of evidence remains weak. CONCLUSION: Ext-DCR offers satisfactory clinical outcomes even though there are many gray areas that need to be addressed in future high-quality studies.

16S rRNA sequencing in chronic dacryocystitis.

CLINICAL RELEVANCE: The pathogenesis of chronic dacryocystitis (CDC) is associated with a variety of bacteria. Investigating microflora has the potential to provide a theoretical basis for preventing and treating CDC. BACKGROUND: 16S rRNA sequencing is a sequence-based bacterial analysis. The application of 16S rRNA sequencing in CDC is rarely reported. METHODS: A case-control study of infected and healthy eyes diagnosed as CDC patients was conducted. Seventy-eight patients were divided into A (conjunctival sac secretions from healthy eyes), B (conjunctival sac secretions from affected eyes), and C (lacrimal sac secretions from affected eyes) groups. The flora of samples was analysed with 16S rRNA sequencing, and the data was analysed using QIIME, R, LefSE and other software. The potential functions were analysed by PICRUSt. RESULTS: A total of 1440 operational taxonomic units (OTUs) were obtained, 139 specific to group A, 220 specific to group B, and 239 specific to group C. There was no significant difference in α index between the three groups. The beta diversity and grouping analysis data indicated that the three groups of flora were similar in species richness and diversity, but there were some differences in composition. In group A, the abundance of Pseudomonadaceae, Chlorobacteria, Moraceae, Staphylococcaceae, Bacillariophyceae, Immunobacterium spp. and Bacillus spp. was higher; in group B, the abundance of Burkholderiaceae, Sphingomonas, Rhizobia, Stalked Bacteria, Sphingomonadaceae, Enterobacteriaceae, Shortwaveomonas spp. was higher; in group C, the abundance of Streptococcus digestiveis, Propionibacterium, Enterobacteriaceae, Anaerobacteriaceae, Propionibacteriaceae, Bacillus spp. Neisseria spp. and Shortactomonas spp. was higher. Six pathways were identified to assess the potential microbial functions. CONCLUSION: Alterations in the microbiota of the conjunctiva and lacrimal sac are associated with the pathogenesis of CDC, which may provide certain guidance for antibiotic treatment of CDC.

Primary Dacryocystorhinostomy for Acute Dacryocystitis: A Systematic Review.

INTRODUCTION: Acute dacryocystitis is a common condition occurring secondary to nasolacrimal duct obstruction. We aim to assess the efficacy of primary dacryocystorhinostomy for the management of acute dacryocystitis. METHODS: A systematic search of the databases PubMed/MEDLINE, Embase, and CENTRAL was performed to December 2023. Data extraction and risk of bias analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Fourteen articles fulfilled inclusion criteria. The results demonstrated that for the treatment of acute dacryocystitis, primary dacryocystorhinostomy (DCR) is anatomically and functionally efficacious, with low complication rates and minimal risk of recurrence. The anatomical success rates for primary endonasal DCR (EnDCR) were 81.8-100%, 83.8-87.5% in delayed EnDCR and 66-100% in delayed external DCR (ExDCR). Functional success was generally defined as a subjective absence of epiphora, which was achieved in 86.4-92.0% of primary EnDCR, and 0-89.5% of the delayed ExDCR cohorts. Two randomized controlled trials established equivalent rates of functional success between primary versus delayed EnDCR (87.5% vs 87.5% and 91.3% vs 92.3%). Increased perioperative bleeding was recorded in 27.8% of primary EnDCR cases in 1 study. ExDCR was infrequently associated with postoperative fistula and scar formation and cicatricial punctal ectropion. The mean length of admission trended to be shorter when the procedure was performed closer to the acute presentation. The admission time for all primary EnDCR cases varied between 1 and 7 days. CONCLUSION: Primary dacryocystorhinostomy is an efficacious and safe management option for acute dacryocystitis. Further analyses of health-economics are required.

Early Endonasal Dacryocystorhinostomy for Acute Dacryocystitis: A Systematic Review and Meta-Analysis.

OBJECTIVE: The aim of this meta-analysis is to compare the outcomes of early endonasal dacryocystorhinostomy (DCR) with delayed DCR in the treatment of acute dacryocystitis (AD). METHODS: A comprehensive electronic search of PubMed, Embase, Web of Science, and the Cochrane Library databases was conducted up to November 11, 2023. Data synthesis was performed using Review Manager 5.4, and forest plots were generated for each outcome measure. Potential publication bias was assessed using funnel plots and Egger's test. RESULTS: Six studies involving 288 patients were included in the meta-analysis. Overall, the success rate of early endonasal DCR was comparable to that in the delayed DCR group (odds ratio [OR] = 1.52, 95% confidence interval [CI]: 0.81-2.85, P = .19). Furthermore, in comparison with the delayed DCR group, early endonasal DCR significantly reduced the time for medial canthus swelling resolution (mean differences [MD] = -4.92, 95% CI: -5.46 to 4-.37, P < .00001) and complete resolution of symptoms (MD = -17.70, 95% CI: -23.88 to -11.52, P < .00001). CONCLUSION: Primary early endonasal DCR seems to be a promising and favorable approach for managing AD with comparable efficacy and faster relief of symptoms compared to conventional delayed DCR.

Misplaced Intracystic Lacrimal Implant- An Unusual Cause of Failed External Dacryocystorhinostomy.

Background: Various techniques of dacryocystorhinostomy (DCR) by an external or endonasal endoscopic approaches are in practice of ophthalmologists and otorhinolaryngologists. The purpose of this paper is to report a case of misplaced intracystic implant in the orbit following external DCR leading to persistence of watering, diplopia and visual diminution. Case Report: A thirty nine year old female patient presented with recurrent left eye pain, swelling over medial side of the left eye, watering, progressive blurring of vision and diplopia after revision external DCR. The ophthalmology examination revealed bilateral decreased vision, left side restricted extraocular eye movements, sub capsular cataract. The computed tomography dacryocystograph (CT-DCG) revealed tubular foreign body in the extra-conal space abutting the medial rectus with proximal block in the nasolacrimal duct. Conclusion: This is the first reported case of misplaced implant following external DCR in the literature. It may be suggested that patients undergoing intracystic larimal implant shall be on close follow up for such an occurrence later for timely intervention.

Nasolacrimal sac foreign body extraction using vitreoretinal forceps in 28 dogs.

PURPOSE: To describe a novel technique of nasolacrimal foreign body extraction in dogs by using a 20G vitreoretinal forceps introduced through the superior lacrimal punctum. METHODS: A retrospective review of the medical records of dogs with dacryocystitis due to nasolacrimal foreign bodies between the years 2001 and 2022 was performed. We recorded the breed, age, affected eye, type and number of foreign bodies, concomitant diseases, and the use of imaging techniques. All animals underwent the same procedure of a 20G vitreoretinal forceps insertion through the upper canaliculus reaching the lacrimal sac and retrograde extraction of the foreign bodies. RESULTS: A total of 28 dogs were included, 16 males and 12 females, with a mean (±SD) age of 4.7 (±3.2) years. The most common breeds were Wire-Haired Dachshund (4/28; 14.29%) and Labrador Retriever (3/28; 10.71%). Additional imaging techniques were used, such as orbital ultrasound in 13 cases (13/28; 46.43%) and computed tomography in one case (1/28; 3.57%). The most common type of foreign body retrieved was grass awns, although seeds and plant debris were also found. Dacryocystitis resolved after removal of the foreign body and appropriate medical therapy was ensured in all cases in the 1-month postprocedure follow-up. CONCLUSION: Extraction of nasolacrimal foreign bodies with vitreoretinal forceps is a novel, noninvasive, and easily applicable technique that, although not successful in all cases, can be attempted before performing more aggressive surgery.

Microbiological isolates and associated complications of dacryocystitis and canaliculitis in a prominent tertiary ophthalmic teaching hospital in northern China.

BACKGROUND: To report the microbiological isolates, aetiology, complications, antibiotic susceptibilities, and clinical remission of dacryocystitis and canaliculitis in a prominent tertiary ophthalmic teaching and referral hospital located in northern China and to offer appropriate recommendations for preventing and formulating drug treatment strategies. METHODS: This prospective study recruited a total of 477 participants who had been diagnosed with either dacryocystitis or canaliculitis. The cohort comprised 307 patients with chronic dacryocystitis, 111 patients with acute dacryocystitis, and 59 patients with canaliculitis. Purulent discharge from the lacrimal duct was collected using a sterile swab and immediately subjected to microbial culture. Antimicrobial susceptibility testing was conducted following established protocols. All participants were scheduled for follow-up visits within 14 days after receiving antibiotic therapy. RESULTS: The present findings indicated that women exhibited a higher susceptibility to the condition, as evidenced by the occurrence of 367 cases in comparison to 110 cases among men. Among the 477 patients, definitive causes were established in 59 individuals, accounting for 12.4% of the patients. Additionally, ocular complications were reported by 132 patients, representing 27.7% of the total. Monocular involvement was observed in the majority of cases, with 402 out of 477 patients (84.3%) affected, while binocular involvement was present in 75 patients (15.7%). In total, 506 microbiological strains were recovered from 552 eyes, with Staphylococcus epidermidis (16.4%) being the most prevalent microorganism. Other predominant isolates included Corynebacterium macginleyi (9.1%), Staphylococcus aureus (5.1%), Streptococcus pneumoniae (4.9%), Haemophilus (4.4%), Propionibacterium acnes (3.5%), and Eikenella corrodens (3.1%). Among the 12 isolated fungi, Candida parapsilosis accounted for 66.7%. The susceptibility to antimicrobial agents tested in gram-negative bacilli (79.5%) was observed to be higher than that of anaerobic bacteria (76.7%) and gram-positive cocci (55.4%). With pharmacological therapy, the remission rate of acute dacryocystitis (72.7%) was found to be higher than that of canaliculitis (53.3%) and chronic dacryocystitis (42.3%). CONCLUSIONS: This study highlights the microbial spectrum of dacryocystitis and canaliculitis, particularly C.macginleyi, E.corrodens and C.parapsilosis, which are also more frequently isolated. Vancomycin and imipenem may be more effective treatment options. Most cases have an unknown aetiology, and essential preventive measures involve postoperative cleansing of the lacrimal passage following eye and nasal surgeries, as well as the proactive management of rhinitis.

Microbiology and Antimicrobial Susceptibility in Adult Dacryocystitis.

Purpose: To investigate the microbiology and antimicrobial susceptibility of dacryocystitis in adults and identify the changing trends over time in Taiwan. Methods: This is a single-centered, retrospective study. We retrospectively reviewed adult patients with dacryocystitis from January 2012 to December 2021 in a tertiary medical center in Taiwan. The pathogens and in vitro antimicrobial susceptibility of the pus cultures from the lacrimal sac were collected. Results: Thirty-five cultures in acute and 211 cultures in chronic dacryocystitis were collected. Of the 220 isolates, a similar proportion of gram-positive (44%) and gram-negative (43%) aerobes were demonstrated in chronic dacryocystitis and more gram-negative aerobes (50%) than gram-positive aereobes (41%) in acute dacryocystitis. The most common pathogens were methicillin-resistant Staphylococcus aureus (MRSA; 28.1%) and Pseudomonas aeruginosa (28.1%) in acute dacryocystitis, while coagulase-negative Staphylococci was the most common micro-organism in chronic dacryocystitis. The effective antibiotics for gram-positive aerobes were vancomycin (100%), moxifloxacin (88%) and trimethoprim/sulfamethoxazole (78%). Meropenem (95%), amikacin (93%), and levofloxacin (91%) were sensitive to more than 90% of gram-negative aerobes in current study. High resistant species were also isolated in our cohort. Conclusion: More gram-negative pathogens and more resistant species are rising in adult dacryocystitis. Understanding the bacteriology and antimicrobial susceptibility of the region is crucial for the empirical antibiotic selection in clinical practice.

Antibiotic utilization in endoscopic dacryocystorhinostomy: a multi-institutional study and review of the literature.

PURPOSE: Utilization of antibiotics for endoscopic dacryocystorhinostomy (endo-DCR) is largely dependent on individual surgeon preference. This study aimed to investigate prescribing practices of pre-, peri-, and postoperative antibiotics and effects on postoperative infection rates in patients who underwent endo-DCR. METHODS: A retrospective chart review of institutional data at two academic centers of endo-DCR cases from 2015-2020 was performed. Postoperative infection rates for patients who received pre-, peri-, and postoperative antibiotics, individually or in combination, and those who did not, were compared via odds ratio and ANOVA linear regression. RESULTS: 331 endo-DCR cases were included; 22 cases (6.6%) had a postoperative infection. There was no significant difference in the infection rates between patients without an active preoperative dacryocystitis who received different permutations of peri- and postoperative antibiotics. Patients who received preoperative antibiotics within two weeks of surgery for preexisting acute dacryocystitis, but did not receive peri- or postoperative antibiotics, had a higher rate of postoperative infections (p = 008). CONCLUSIONS: Our data suggest antibiotics may be beneficial only when patients have a recent or active dacryocystitis prior to surgery. Otherwise, our data do not support the routine use of antibiotic prophylaxis in endo-DCR.

Epstein-Barr Virus-Associated Acute Dacryocystic Retention.

Epstein-Barr virus (EBV) associated dacryocystic retention presents with an acute swelling in the lacrimal sac area with epiphora and lymphadenopathy. The patient would usually have a preceding history of infectious mononucleosis with clinical features of fever, pharyngitis, preauricular and cervical lymphadenopathy, hepatosplenomegaly, subclinical hepatitis, nausea, and palatine petechiae. The present case is of a 3-year-old child who presented with a sudden painless swelling in the lacrimal sac region with epiphora. Investigations and a biopsy helped in establishing the diagnosis of EBV-associated dacryocystic retention which resolved completely with conservative management.
