Abstract
STUDY OBJECTIVE To study the performance of a pre-loaded Monoka stent in the management of congenital nasolacrimal duct obstruction (CNLDO). STUDY DESIGN Non-randomized study of consecutive cases. MATERIALS AND METHODS A preloaded classic Monoka silicone stent contained entirely inside its introducer (Lacrijet) was used to treat a consecutive series of subjects with CNLDO over an 11-month period (May 2019-March 2020). Only subjects with chronic symptomatic CNLDO were included. Subjects with intermittent tearing, canalicular pathology, trisomy 21, facial cleft, or history of lacrimal surgery were excluded. Intraoperative findings were recorded, including the degree and location of the nasolacrimal obstruction, successful metal to metal contact with the probe, any difficulties encountered by the Lacrijet device itself, procedure duration, tolerability of the fixation punctal plug, and finally, inspection of the stent after withdrawal of the inserter. Functional success was defined as disappearance of all symptoms of epiphora. RESULTS A total of 45 preloaded Monoka Lacrijet stents (Lcj) were placed consecutively in 38 children. The mean age was 27.9 months (12-78 months). The mean procedural duration was 2.8minutes (range: 1-10min). The overall success with disappearance of all symptoms of epiphora was 88.8% (40/45). Surgery in cases of simple mucosal stenosis was successful in 92.2% (35/38) of cases, with a mean follow-up time of 7.9 months (range: 1 to 12 months). The duration of stent intubation was for this group was 32 days (range: 1-103). The surgical outcomes for the other 7 cases with more complex intraoperative findings are summarized in the publication. All withdrawn probes were intact. CONCLUSIONS The Lacrijet stent system is a simple and reliable pushed intubation device for CNLDO in appropriately selected cases where bony stenosis of the canal is minimal.

Abstract
Purpose To compare conventional and endoscopic probing for congenital nasolacrimal duct obstruction in infants. Methods Conventional probing was performed in 22 eyes of 18 patients, age range 7–14 months (mean 11.4 months). Probing was done with intranasal endoscopic visualization in 18 eyes of 14 patients, age range 7–13 months (mean 11.2 months). All were primary probing cases. Results After conventional probing 2 of the 22 cases required reprobing. After endoscopic probing only 1 of the 18 cases required reprobing. Conclusions In most cases of congenital nasolacrimal duct obstruction endoscopy is not required; however, in failed cases direct visualization of the inferior meatus with endoscopic guidance may be helpful.

Abstract
PurposeTo report the outcome of a step-by-step treatment approach for congenital nasolacrimal duct obstruction (CNDO).MethodsThree-hundred and fifty eyes with CNDO were included in the study. A number of treatment methods were applied systematically until a successful outcome was achieved. Listed in order from simple to more complex, the following methods were used: conservative management (massage and topical antibiotics), high-pressure syringing, probing, and silicone intubation. Treatment efficacy was determined according to age (Group 1: 0–6 months, Group 2: 7–12 months, Group 3: 13–24 months, Group 4: 25–72 months) and success rates were compared.ResultsConservative management was applied only in children less than 1 year of age, and was successful in 91.8% of Group 1 and 60% of Group 2 eyes. The difference between these two success rates was significant (p = 0.003). High-pressure syringing was performed in children under 24 months of age, with success rates of 41.7% in Group 1, 33.3% in Group 2, and 12.5% in Group 3. The overall success rate for first probing in all groups was 76.1%, with a range of 69.4% to 80.9%. After second probing, the overall cure rate for the entire cohort was 88.0%, with a range of 74.9% to 94.8%. There was no real difference in probing cure rates relative to age (p > 0.05). Silicone intubation was indicated and performed in two eyes of Group 2 children, three eyes of Group 3, and nine eyes of Group 4. Two ducts in Group 4 eyes remained obstructed after silicone intubation.ConclusionsThe systematic treatment approach to CNDO, including conservative management and minimally invasive procedures such as high-pressure syringing, probing, and silicone intubation, is highly successful. In this study, the cure rate for this combined approach was 100% in youngsters under 2 years of age and 94.5% in children 2 to 6 years old.

Abstract
BACKGROUND One of the most frequent issues in pediatric ophthalmology concerns congenital nasolacrimal duct obstruction (CNLDO). Typically, irritation of the medial eyelid angle occurs during the first days of life and later increased epiphora appears as tear production is still reduced in young infants. In the case of intrasaccal or postsaccal nasolacrimal duct stenosis, a chronic dacryocystitis develops. METHODS Modern minimally invasive diagnostics and therapy of CNLDO are reviewed by means of a search of the recent literature and reflection of own experiences. RESULTS An early diagnosis of CNLDO is desirable. If conservative therapeutic approaches fail, invasive procedures have to be considered. Probing and high pressure syringing of the nasolacrimal ducts remains the therapy of choice. Further therapy options, such as balloon dacryoplasty and dacryoendoscopy are also available. Additionally, due to improvement of the surgical techniques a minimally invasive approach is possible even for dacryocystorhinostomy; nevertheless, this procedure should be considered only as a last resort. CONCLUSION Precise classification of CNLDO and knowledge about the possible treatment options are important. Lacrimal surgery in childhood is dominated by transcanalicular procedures. Advanced minimally invasive techniques, such as dacryoendoscopy or modern autostable intubation sets have to be emphasized. All therapeutic interventions can be summarized using a staged therapeutic concept, which should be used individually and patient-centered.

Abstract
PURPOSE To evaluate the cause of nasolacrimal duct obstruction through confirmation by nasal endoscopic findings of Hasner's valve and to report the success rate of monocanalicular silicone intubation (MCI) for the management of congenital nasolacrimal duct obstruction (CNLDO). METHODS Seventy-seven eyes of 56 patients with CNLDO underwent MCI under nasal endoscopic visualization of the terminal end of the obstructed nasolacrimal duct at the Korea University Ansan Hospital and Guro Hospital from October 2008 to March 2013. The following demographic information was analyzed: age, sex, endoscopic findings of Hasner's valve during operation, complications, and outcomes. The main outcome measures were disappearance of epiphora symptoms beginning the first 2 months after removal of the silicone tube. The silicone tube was removed under topical anesthesia in the office between 2 and 3 months, postoperatively. RESULTS The mean (± SD) age of the study population was 29.8 (± 26.9) months (range: 6 months to 12 years). Under nasal endoscopic view, 45 ducts (58.4%) had a thin membranous obstruction or had a simple stenotic opening of Hasner's valve. Seven ducts (9.1%) had thick obstructing membranes with probe passage under the lateral nasal mucosa. Twenty-three ducts (29.9%) showed the probe tip protruding through balloon-like nasal mucosa. Two ducts (2.6%) appeared to have probe protrusion through a stretchable valve. The overall success rate was 89.6% (69/77). The incidence of tube prolapse and tube loss was 18.2% (14 eyes) and 13.0% (10 eyes), respectively. No other complications were observed. CONCLUSIONS Monocanalicular silicone intubation under nasal endoscopic visualization of the terminal end of the obstructed nasolacrimal duct can be an effective procedure for the management of CNLDO.

Abstract
Probing is a reliable surgical intervention for the management of congenital nasolacrimal duct obstruction (CNLDO). However, it is a blind procedure that carries the risk of false passage formation. Moreover, its success rate is variable, with unexplained causes of failure. Recent literature suggests the use of nasal endoscopic-assisted probing to minimize nasal mucosal trauma, decreases the chance of creating a false passage and provides the optimum management option of different congenital variants of nasolacrimal duct obstruction. Nasal endoscopic-assisted probing has more or less consistent success rates varied between 85% and 98% compared with probing success rates, which vary between 55% and 95% despite having almost the same age range.

Abstract
PURPOSE To evaluate the intraoperative prognostic factors for probing outcome in children with congenital nasolacrimal duct obstruction (CNLDO). METHODS In a prospective interventional study, 69 eyes of 60 children aged 12 to 24 months with CNLDO underwent probing and irrigation. All procedures were performed by a single oculoplastic surgeon. The nature of the obstruction was classified by the surgeon as simple or complex. The fluency of irrigation after probing was defined as easy or difficult. Treatment success was defined as no epiphora or mucus discharge at 3 months after probing. RESULTS The mean age at the time of probing was 15.3±3.1 months (range, 12-23 months). Treatment success was achieved in 56 of 69 eyes (81.2%). There was a significant difference in success rate of probing in eyes with simple obstruction (87.8%) compared with complex obstruction (65%) (p=0.02). Also, there was a significant difference in success rate of probing in eyes with easy irrigation (100%) compared with difficult irrigation (53.6%) (p<0.001). CONCLUSIONS Probing was more successful in eyes with simple obstruction or easy irrigation in children aged 12 to 24 months. The fluency of irrigation as an objective finding was a reliable intraoperative prognostic factor for probing success.

Abstract
PURPOSE To show the efficiency of repetitive probing performed with intranasal endoscopic imaging in cases who underwent unsuccessful probing and the accompanying nasal pathologies. METHODS Eighty-four eyes of the 64 patients in whom primary probing was found to be unsuccessful were included in the study. Cases were divided into 3 groups, depending on the number of unsuccessful attempts (1 [group 1], 2 [group 2], and 3 [group 3] unsuccessful probings). Diagnosis of congenital nasolacrimal duct obstruction was confirmed by history taking, clinical examination, and fluorescence disappearance test. All cases underwent nasal endoscopic-assisted probing and were followed up on the first week, first month, and third month following the procedure. RESULTS There were 50 eyes in group 1, 23 in group 2, and 11 in group 3. The causes of failure that were determined with endoscopy were as follows: functional insufficiency 8.3%, lower nasal concha tension 4.7%, thin membrane in Hasner valve 3.6%, thick membrane and fibrosis in the distal side of the duct 21.4%, probe progressed submucosally on the nasal wall 33.3%, different exit location in the nose 20.2%, nasal mucosa ballooning in the distal side of the duct 4.7%, mucocele 2.4%, and nasal polyposis 1.2%. The success rate in the groups was estimated as 86% in the first group, 69.5% in the second group, and 54.5% in the third group. CONCLUSIONS Performing the repetitive probings via nasal endoscopy provided information about the location and the shape of the obstruction and the opportunity to approach, according to the cause of the failure.

Abstract
BACKGROUND Conventional probing is a blind procedure with a variable success rate. This article evaluates the role of nasal endoscopy during probing to expose, explain, and manage the possible causes for probing failure. METHODS In a prospective study, 169 eyes of 130 children (4 to 48 months old, median age = 1 to 6.2 months) with primary congenital nasolacrimal duct obstruction (NLDO) underwent probing under direct nasal endoscopic visualization. NLDO was diagnosed according to the patient's history, clinical examination, and dye disappearance test. No patient had previously undergone lacrimal surgery. The main outcome measures were absence of tearing and discharge and negative dye disappearance test in the affected eye. Patients were observed at 1 week, 1 month, and 4 months postoperatively. RESULTS Of the 169 obstructed ducts, 164 became patent after the first probing and 5 became patent after the second probing, with a total success rate of 100%. During probing, suspected causes for failure included thick membranous obstruction with false passage laterally, redundant membranous obstruction with trap-door re-closure, stretchable membranous obstruction with elastic valve re-closure, and narrow terminal end of the duct with false passage medially. Such causes were predicted and managed intraoperatively. CONCLUSION Using nasal endoscopy during probing enables the surgeon to avoid the most likely causes for probing failure. Such intervention could increase the success rate of probing compared to probing without endoscopy.

Abstract
OBJECTIVE To study the behavior of a "pushed" monocanalicular stent by means of nasal endoscopy. PATIENTS AND METHODS Four children (six affected sides) with congenital nasolacrimal duct obstruction were treated with monocanalicular intubation with an anchoring plug. The children's mean age at the time of the operation was 33 months (range, 30-37 months). The procedure began with probing in order to verify (a) dacryostenosis (simple or extensive nasolacrimal duct impatency) and (b) the metal-to-metal contact in the lower nasal meatus. The stent was similar to a Monoka(TM), but the guide (a malleable stainless steel probe) is located inside the silicone stent rather than projecting from it. The silicone's total length is 40 mm and the external diameter 0.96 mm. Simultaneously, the guide acts to catheterize the nasolacrimal duct by pushing the silicone through the upper and lower parts of the outflow system. The guide is removed via a punctal approach. This mode of intubation dispenses with the nasal recovery step. Nasal endoscopy was used to monitor (a) the position of the stent in the lower nasal meatus (free or submucosal), (b) mucosal damage and bleeding, and (c) the behavior of the silicone tube during removal of the guide. RESULTS Because of the complexity of nasolacrimal ducts, two of the six sides were treated with the classical Monoka intubation method of pulling the silicone tubing out from the nasal exit of the duct (the pull technique). The pushed intubation method was used for the four simple nasolacrimal stenoses, with no problems whatsoever. In all four cases, endoscopic examination showed (a) no submucosal tunneling (false passage), (b) no noteworthy mucosal damage, and (c) no retraction (bunch-up) of the silicone tube during the metal guide removal. No particular complications were reported during the procedure or the intubation period, which lasted an average of 3 weeks. The stents were removed in the consulting room. Tearing ceased during the 1(st) week in two cases, during the intubation period. Tearing persisted throughout the intubation period in the other two cases, but ceased during the week following stent removal. The follow-up lasted 2 months. CONCLUSIONS The pushed procedure simplifies monocanalicular nasal intubation. Its indications remain to be determined.

Abstract
PURPOSE To report a new technique for silicone tube fixation, after successful intubation for congenital nasolacrimal duct obstruction, to minimize its lateral dislocation. METHODS Thirty patients (40 eyes) aged 20 months to 5 years (median, 28 months) were treated using the Ritleng bicanalicular lacrimal intubation system. After drawing the silicone stent out of the nose, a piece of 7-O Prolene suture was tied securely around one of its limbs. This limb was then pulled up, pulling the tied end of the Prolene suture to the medial canthal area. The same procedure was repeated with the other limb of the stent, pulling up the other Prolene suture end. This suture end was then un-tied. After adjusting the exposed silicone loop, the free end of the Prolene suture was tied securely to the corresponding part of the silicon stent. The nasally drawn two ends of silicone tube were tied in a single square knot. After 2 to 3 months, stents were removed in the medical office for all the patients. RESULTS This technique was used successfully for all the patients. Of the 40 tubes in this study, 39 did not displace and one tube was displaced laterally due to loosely tied Prolene suture. On follow-up, the trans-sac suture was well tolerated and no complications were noted. CONCLUSION The trans-sac fixation suture prevents lateral displacement of square-knotted silicone tube, which still can be removed easily at the physician's office.

Abstract
PURPOSE To determine the success rate of initial probing in children with congenital nasolacrimal duct obstruction (CNLDO) at different ages using nasal endoscopy, and to identify the anatomical sites of blockage within the drainage system. METHODS A total of 87 eyes from 67 consecutive children with CNLDO underwent endoscopic nasolacrimal duct (NLD) probing under general anaesthetic. Patients who had had previous probings were excluded from the study. Diagnosis was based on history of epiphora since birth or shortly after, and fluorescein dye disappearance test (FDDT). Cure was judged as complete or near-complete remission of symptoms and signs and a normal FDDT. RESULTS The age range was 12-91 months (mean 32.3 months). The success rates of probing were: 100% (58/58) for atresia and stenosis at the lower NLD, 100% (13/13) for punctal stenosis, 55.6% (5/9) for functional epiphora, and 0% (0/7) for canalicular and upper NLD obstruction. Age was not found to significantly affect the outcome of probing, whereas site did. Obstruction at canalicular or upper NLD level became more common with increasing age. CONCLUSION Probing of the nasolacrimal system using the endoscopic approach allows direct visualisation of the distal nasolacrimal duct, which facilitates diagnosis of the anomaly at this site. More complex proximal anomalies became increasingly prevalent in older children, which accounted for the poorer results with increasing age. Site of obstruction has a greater bearing on outcome than patient age.

Abstract
PURPOSE To assess the results of our protocol of repeated probing for the treatment of congenital nasolacrimal duct obstruction in various presentations. METHODS A total of 1600 patients (1748 eyes) with congenital dacryocystitis (850 boys, 750 girls; age range, 1 month to 48 months [mean 16.54 +/- 12.21 months]) were included. Diagnosis was confirmed by history of tearing, crusting of lids, and a boggy swelling over inner canthal region, which on pressure ejected mucopurulent discharge through punctum. Antibiotic eye drops were instilled five times a day for a week in affected eyes after the mother pressed the sac area and cleaned the discharge. The cases that were not relieved were subjected to sequential probing dilating with an increasing diameter probe repeated in failed cases second and third times at 1-week interval. RESULTS Medical treatment was effective in only 60 eyes (3.43%). Probing and syringing achieved successful results in 790 eyes (100%) aged 1 month to 12 months; 330 eyes (99.40%) aged 12 months to 18 months; 200 eyes (98%) aged 18 months to 24 months; 150 eyes (95.24%) aged 24 months to 36 months; and 158 eyes (89.87%) aged 36 months to 48 months. The cure rate with first probing was 98.10%, second probing was 99.64%, and third probing was 100%. CONCLUSIONS Our protocol of medical regime and early probing repeated two to three times was very effective in the treatment of nasolacrimal duct obstruction at all ages. A second and third probing was recommended after 1 week of the first probing with successful results if first probing failed.

Abstract
PURPOSE To report the incidence of intranasal abnormalities in children with nasolacrimal duct (NLD) obstruction and the results of treatment, which included nasal endoscopic removal of abnormal tissue. METHODS Nasal endoscopy was performed prospectively in 22 infants with mucoceles; in 97 children > or = 18 months at the time of initial NLD probing; and in 59 children with persistent NLD obstruction after previous probing. Endoscopic removal of abnormal tissue was performed in addition to NLD probing or balloon-catheter dilation. RESULTS NLD cysts were found in 22 of 22 (100%) infants with mucoceles. Cysts or other abnormalities of the distal duct were found in 6 of 97 (6.2%) children > or = 18 months at the time of initial probing and in 5 of 59 (8.5%) children whose previous NLD probing was unsuccessful. Surgery was successful in 91% of patients. CONCLUSION Nasal endoscopy identified intranasal anatomic abnormalities of the distal nasolacrimal duct uniformly in infants with mucoceles and in 6% to 9% of older children with complicated NLD obstruction. Treatment, including endoscopic removal of abnormal tissue, was successful in most patients. The use of nasal endoscopy may improve the treatment of patients with these disorders.

Abstract
PURPOSE To determine whether pediatric nasal endoscopy improves treatment success in recurrent nasolacrimal duct obstruction. METHODS A retrospective analysis was carried out on 2 nonrandomized cohorts of consecutively treated patients who had one failed nasolacrimal duct probing at the Hospital for Sick Children, University of Toronto. The first cohort of 24 consecutive patients (32 eyes), group A, was treated with Crawford silicone tube intubation by one ophthalmologist (R.C.P.). The second cohort of 23 consecutive patients (33 eyes), group B, was treated with repeat probing by a second ophthalmologist (A.V.L.) in conjunction with nasal endoscopy by one otolaryngologist (V.F.). Abnormalities found on endoscopy were treated accordingly, and no tubes were inserted. Follow-up, through phone interviews or office visits, was conducted to assess the patients' symptoms. RESULTS Group A patients were older at both the first probing (P = .048) and the second procedure (P = .012). No significant difference in the failure rates was found, with treatment failing in 3 eyes (2 patients) in group A and in 5 eyes (4 patients) in group B (P = .479). Interestingly, 17 of the 32 tubes in group A were extruded in 1 month or less. Also, 28 of 33 eyes in group B had abnormalities on endoscopy-some, multiple. Twenty-two eyes underwent inferior turbinate infracture: 5 had redundant mucosa, which was removed, and 6 had abnormal openings of the inferior meatus. CONCLUSIONS We were unable to show any benefit of nasal endoscopy over intubation of the nasolacrimal system with silicone tubes in the treatment of failed probings despite the identification and treatment of abnormalities. The study was limited by its low power to detect differences because of the small number of patients and the high success rate of the traditional treatments for congenital nasolacrimal duct obstruction.

Abstract
OBJECTIVE The rate of false passages during probing for congenital nasolacrimal system obstruction (CNLO) is a major limiting factor for a successful outcome. This shortcoming may be decreased with the use of a nasal endoscope during probing. This approach is particularly important in the probing training of ophthalmology residents. METHODS An experienced pediatric ophthalmologist performed probings on 11 eyes, and a group of ophthalmology residents under his supervision performed probings on another 11 eyes for CNLO. Their claims of a successful or unsuccessful procedure were evaluated with nasal endoscopy by an ear--nose--throat (ENT) surgeon. The age range of the patients was 8-23 months. RESULTS The ophthalmologist made two false passages, one of which he was aware, out of 11 eyes. The residents had five false passages, two of which were unclear to them, out of another 11 eyes. No false passages occurred in obstructions at the level of the Hasner valve. None of the successful probings required more than a 30 mm probe introduction into the nasolacrimal canal from the inferior punctum. CONCLUSION It seems justified to have a nasal endoscopic evaluation, performed by an ENT surgeon, for probings during the training program of ophthalmology residents. Difficult cases with stenosis proximal to the inferior meatus, prior false passage experience on a particular case, and any indication for silicone tube implantation will benefit from the use of an endoscope during the procedure. In order to achieve the best results in CNLO, the collaborative teamwork of an ophthalmologist and an ENT specialist is necessary.

Abstract
BACKGROUND Congenital nasolacrimal obstruction is usually the result of failure of canalisation of the distal end of the nasolacrimal duct. The most common outcome is spontaneous resolution, but some children do require surgical treatment by probing. Probing is a blind procedure with a recognised failure rate. METHODS In 52 lacrimal systems of 40 children nasal endoscopy was combined with a "stepwise" systematic probing in an attempt to improve the outcome and reduce the number of repeat procedures. RESULTS Combined nasal endoscopy and probing improved the understanding of outflow obstruction in young children. The success of the procedure depended upon the level of the obstruction within the outflow system. Formation of a false passage was seen in six cases (15%). The probe was rerouted under direct visualisation in these cases to form a functioning passage. Reasons for failure were identified in those who did not have a successful outcome and only one repeat procedure was required. CONCLUSION Using nasal endoscopy the area of lacrimal outflow obstruction at the lower end of the nasolacrimal duct can be observed directly and it is possible to guide the progress of probing under direct vision. This gives better information about the nature of the obstruction, minimises the formation of false passages, and allows a wider range of treatment options under a single anaesthetic.
