To investigate long‐term outcome and report reoperation rate of non‐infected, complete acquired lacrimal drainage obstruction (ALDO ) treated with canaliculodacryocystoplasty (CDCP ) depending on site of stenosis.
Consecutive adult patients with non‐infected, complete ALDO treated with CDCP were followed for 76 months. Location of stenosis at preoperative visit and intraoperative probing was recorded, and during follow‐up, recurrence of stenosis prompting additional surgery and complications were noted. Survival analysis was applied to compare reoperation rate depending on site of stenosis. A follow‐up questionnaire was sent to patients not requiring reoperation asking to grade current epiphora problems.
Among 85 included cases (71 patients), 57 were classified as canalicular stenosis and 28 as nasolacrimal duct obstruction (NLDO ) preoperatively. At the end of follow‐up, 39% (33/85) of cases had required additional surgery due to persistent/recurrent symptoms. No statistical difference was found between these groups.
During CDCP , 25 of the 57 preoperatively classified canalicular stenosis were found to have an additional obstruction below the sac. The group with only canalicular stenosis had a statistically significant higher survival compared with cases with NLDO or multiple obstructions (p = 0.03). Of patients responding to the follow‐up questionnaire, 11/37 cases experienced epiphora often or constant.
Treating complete NLDO with CDCP results in a high reoperation rate and seems an insufficient alternative. Canaliculodacryocystoplasty (CDCP ) may be discussed if preoperative examination indicates canalicular stenosis and dacryocystorhinostomy is not desirable. However, the patient needs to be aware of the higher risk for additional surgery, especially if a second stenosis is found during probing.

Acquired nasolacrimal duct obstruction (NLDO) is a common problem leading to epiphora, the pathophysiology of which remains unclear. Culture-based studies have found Staphylococcal species to be the most prevalent organisms, reported in 47% to 73% of patients with NLDO. Recently, culture-independent molecular methods of have allowed more comprehensive detailing of local microbiota. This study aims to evaluate the sinonasal and lacrimal microbiome of patients undergoing dacryocystorhinostomy for NLDO using 16S-amplicon sequencing.
Guarded intraoperative swabs were taken from the middle meatus (MM), inferior meatus, and the opened lacrimal sac of 14 NLDO patients undergoing dacryocystorhinostomy and from the inferior meatus and MM on the contralateral unaffected side. MM swabs from 12 control patients were compared with NLDO patients.
Comparing microbiota at lacrimal sac to MM and inferior meatus sites reveals that the lacrimal sac microbiome is dominated by Staphylococci (36.3%) and Corynebacterium (35.8%). No significant genus differential abundance between the 3 sites, and between the ipsilateral and contralateral sinonasal swabs, and no convincing evidence of reduced alpha diversity in all comparisons. There was a statistically significant lower relative abundance of Corynebacterium (37.6% vs. 65.1%; p = 0.035) in the MM of NLDO patients compared with controls.
The lacrimal sac microbiome in acquired NLDO is similar to the sinonasal microbiome. The relative abundance of Corynebacterium was reduced compared with controls. These findings suggest that an altered sinonasal microbiome may be associated with NLDO, either as a consequence or a risk factor, and merits future research.
The authors have demonstrated a decreased relative abundance of Corynebacterium at the middle meatus of patients with ipsilateral nasolacrimal duct obstruction (NLDO), compared with controls, and that the lacrimal sac microbiome is similar to the sinonasal microbiome. An altered microbial state may, therefore, be associated with NLDO, either as a consequence or a risk factor, and merits future research.

To evaluate the effect of a topical steroid instillation on recently developed incomplete nasolacrimal duct obstruction (NLDO) evaluated by using anterior segment optical coherence tomography (ASOCT).
Forty-nine eyes of 31 patients with incomplete NLDO who developed epiphora within 3 months were recruited and treated with a topical steroid for 3 months. Tear meniscus height (TMH) and area (TMA) were measured by ASOCT. The treatment was considered to be effective when there was improvement of subjective epiphora, normal tear meniscus on slit lamp examination, a fluorescein dye disappearance test with grade 0 or 1, and TMH < 250 μm on ASOCT. The treatment effectiveness and associated factors were analyzed.
Treatment was effective in 24 eyes (49.0%) after 6 months of follow-up. TMH and TMA at 3 months were significantly decreased in the effective group on ASOCT (TMH: from 385 to 268 μm, p = 0.002, TMA: from 0.0564 to 0.0266 mm2, p = 0.001, Wilcoxon test). In the effective group, the eyes with normal tear meniscus at 1 month were significantly more frequent than those in the ineffective group (p < 0.001, Fisher’s exact test). No patient in the effective group required further invasive management during 3 years of follow-up.
Topical steroid instillation has a significant therapeutic effect on recently developed incomplete NLDO. Additional invasive procedures were avoided in half of the subjects.

A 68-year-old man with known history of IgG4-related disease presented with a 1-year history of mucoid discharge OD and progressive proptosis OS. MRI showed diffuse enlargement of the left lacrimal gland along with prolonged infiltrative changes involving the left extraocular muscles, supraorbital nerve, and infraorbital nerve. No identifiable masses were noted in either nasolacrimal drainage system on MRI. Due to clinical evidence of nasolacrimal duct obstruction, a right external dacryocystorhinostomy was performed along with biopsies of the right lacrimal sac and left lacrimal gland. Immunohistochemical stains identified IgG4-positive plasma cells in the biopsy of the right lacrimal sac indicative of secondary acquired nasolacrimal duct obstruction despite the absence of mass forming lesions on exam and nasolacrimal imaging. This report is the first to describe nasolacrimal drainage system IgG4-related ophthalmic disease involvement in an otherwise clinically and radiographically normal appearing tear drainage system.

Background: Endoscopic dacryocystorhinostomies (eDCRs) show patency rates between 81% and 94%. However, dacryocystorhinostomy (DCR) failure and the need for revision remain a significant challenge. One of the principal challenges in revision eDCR is the need to surgically identify the correct osteotomy site and maintain long-term patency in the setting of previously instrumented and potentially scarred tissue. At the same time, the surgeon must assume that the blood supply to the commonly described anterior and posteriorly pedicled flaps has been compromised.
Objective: The objective of the study is to describe a novel flap technique for revision eDCR.
Methods: The superior based mucosal flap is a novel technique that provides a vascularized mucosa preserving technique in revision eDCR despite previous instrumentation of the lacrimal system. This technique provides wide exposure of the revision osteotomy site while simultaneously allowing a viable mucosal flap to be replaced at the conclusion of the procedure, thereby minimizing bone exposure and cicatricial restenosis.
Results: The authors have utilized this technique in 13 procedures with 100% positive identification of the lacrimal sac, a 0% complication rate, and a 100% success rate after a mean follow-up of 26.93 ± 10.33 months (range 6–35 months).
Conclusion: The eDCR using the superior pedicled mucosal flap provides excellent exposure of the maxillary bone and the lacrimal sac. This method preserves vascularity of the flap using a superiorly based pedicle which is typically inviolate during both open and endoscopic primary DCR. The mucosal flap can then be replaced, thereby minimizing bone exposure and optimizing patency.

Purpose: The purpose of this article is to present a novel technique, as well the histopathological findings, of dacryoendoscopic guided nasolacrimal duct (NLD) biopsy for recurrent nasolacrimal duct obstruction (NLDO).
Methods: This study involved subjects with recurrent NLDO. Direct endoscopic probing or sheath-guided endoscopic probing was used for the initial intubation in all treated eyes, and the stent had been removed at between 2 and 11 months (mean 3.5 months) post-intubation with dacryoendoscopic confirmation of patency and mucosal regeneration. Biopsy specimens were obtained by scraping the recurrent lesion by sheath advancement. Histopathological examination and immunohistochemical (IHC) staining were performed.
Results: In five patients (two males and three females, mean age: 71.2 ± 5.6 years [range: 61–78 years]) with recurrent NLDO, biopsy specimens were obtained from six ducts of six eyes, and stratified epithelium and a mixed inflammatory cell infiltrates were identified. IHC staining was positive for cytokeratin (CK)4 and CK13, and negative for paired box protein Pax-6.
Conclusions: This novel technique enabled a minimally invasive biopsy of the NLD to be obtained, and IHC staining indicated the presence of mucus epithelium, thus suggesting squamous metaplasia of the usual respiratory epithelium which likely occurs secondary to chronic inflammation.

Although generally safe, hyaluronic acid rejuvenation of periorbital tissue has been reported to cause minor and major adverse events. The authors document a case of nasolacrimal duct obstruction due to hyaluronic acid rejuvenation of the tear trough. Nasolacrimal duct obstruction immediately resolved following irrigation of hyaluronidase into the affected lacrimal system. To the authors’ knowledge, this is the first reported case of nasolacrimal duct obstruction due to filler injection.

The aim of this study was to explore the pathological changes of the nasolacrimal duct in rabbits with experimentally induced obstructive dacryocystitis in correlation with lacrimal endoscopic findings.
The rabbit model of obstructive dacryocystitis was created by injecting 0.15 ml of self-curing resin into the lacrimal duct. The control group received 0.15 ml of normal saline. Within 16 weeks after the obstructive, lacrimal endoscopy and pathological examination of the nasolacrimal duct were conducted at different time points of 1, 2, 4, 8, and 16 weeks.
In the control group, lacrimal endoscopy revealed pink and smooth mucosa; and the pathological analysis revealed an epithelial layer that was composed of superficial columnar cells and a deep basal epithelial layer. The experimental rabbits showed clinical manifestations of obstructive dacryocystitis a week after the injection of self-curing resin. At weeks 1 and 2, the lacrimal endoscopy showed mucosal hyperemia and hemorrhagic spots on the nasolacrimal duct; and the pathological features included epithelial cell swelling and inflammatory cell infiltration. At weeks 4 and 8, the experimental group showed alternatively red and white mucosa under the lacrimal endoscopy, and the pathological features included proliferative epithelium accompanied by papillary hyperplasia. At week 16, the experimental group showed pale and coarse mucosa and white membrane-like layer covering the mucosal surface, and the pathological features included epithelial necrosis, squamous metaplasia, and sub-epithelial fibrosis.
The mucosa of the nasolacrimal duct showed different pathological features at different time points after lacrimal duct obstruction, which was well correlated with the endoscopic findings. It is possible to predict the pathological stages by the endoscopic observation in NLOD patients.

Purpose: In evaluating epiphora and its management, the bottom line for all stakeholders is whether an intervention confers any real benefit on quality of life. A review was conducted to identify and appraise patient-reported outcome measures (PROMs) in surgically amenable epiphora.
Methods: A systematic search was conducted of studies relating to surgical intervention for epiphora. Patient-reported outcome measures were identified and assessed against standard criteria.
Results: Of 30,544 identified articles, 227 were eligible for data extraction. Of these, 69% reported a PROM as the primary outcome. PROMs identified included single-item symptom scores (48% of primary outcome PROMs), single-item reports of improvement (30%), the Glasgow Benefit Inventory (3%), Lacrimal Symptom Questionnaire (0.5%), Nasolacrimal Duct Obstruction Symptom Score (0.5%), Ocular Surface Disease Index (0.5%), Visual Function Questionnaire-25, the Short Form-36 Health Survey, and 3 other symptom scores. None were developed through consultation with the target population, and there was inadequate testing of content validity. The strengths and limitations of each PROM are presented, with regard to interpretation, responsiveness, reliability,
Discussion: The importance of robust and psychometrically sound PROMs is essential if the under-reporting of quality of life improvement in patients treated for epiphora is to change. Recommendations for the use of each identified PROM are discussed.
Conclusions: Several PROMs have been used in the recent literature to evaluate patients undergoing surgery to treat epiphora. Assessed against standard criteria, no PROM has proven to be both psychometrically robust and clinically meaningful for use in this population. Future PROM development should be guided by this standard framework.

Purpose: To determine if patients with primary acquired nasolacrimal duct obstruction (PANDO) have an increased prevalence of gastroesophageal reflux disease (GERD) compared to the general population.
Methods: Cross-sectional case–control study. The Mayo Clinic Reflux Disease Questionnaire (RDQ) is used to help physicians diagnose GERD. The retrospective group consisted of patients who previously had a dacryocystorhinostomy (DCR) over a 4-year period by one surgeon (JTH) at one institution. The prospective group included consecutive patients undergoing DCR over an 8-month period for PANDO. The control group consisted of patients at our institution who did not have complaints related to nasolacrimal duct obstruction (NLDO) or a known history of NLDO. The RDQ score or a previous diagnosis of GERD was recorded for each patient. The prevalence of patients with GERD in each of the groups was compared to that in the control group using the Fisher exact test.
Results: Nine (7.7%) of 117 patients in the control group were found to have GERD. Twenty-four of 65 (36.9%) patients in the retrospective cohort were found to have GERD. Twelve of 18 (66.7%) patients in the prospective cohort were found to have GERD. When the prospective and retrospective groups were compared to the control group, the presence of GERD was higher in patients with NLDO (p < .0001).
Conclusion: Based on the results of this study and compared to the general population, GERD has an increased prevalence in patients with PANDO. GERD may have a role in the development of PANDO.
