Eye-Related Adverse Events After I-131 Radioiodine Therapy: A Systematic Review of the Current Literature. Endocr Pract 2024:S1530-891X(24)00507-X. [PMID: 38697307 DOI: 10.1016/j.eprac.2024.04.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 03/11/2024] [Accepted: 04/25/2024] [Indexed: 05/04/2024]
Abstract
OBJECTIVE Although I-131 is relatively safe, there is limited focus on probable eye-related side effects after radioactive iodine (RAI) therapy. Thus, we aimed to provide evidence for the adverse outcomes of I-131, exclusively in patients with thyroid cancer. METHODS A systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was designed to examine the ocular complications of RAI therapy. Databases including PubMed, Scopus, and Web of Science were searched until October 2023 with specific thyroid neoplasms, ophthalmology and iodine terms. After thorough screening and review, relevant data were extracted. RESULTS The database search yielded 3434 articles, which resulted in the final 28 eligible studies. These studies investigated ophthalmic symptoms following RAI therapy, classifying them as obstructive diseases (for example, nasolacrimal duct obstruction; median incidence rate: 6.8%), inflammatory symptoms (median incidence rate: 13%), and cataracts (median incidence rate: 2.5 and 5%). The most common time interval between RAI therapy and the onset of symptoms was within the first 12 months and then declined in the preceding years. A strong positive correlation was observed between higher I-131 doses of more than 100 to 150 mCi (3.7-5.55 GBq) and the risk of symptom development. Ages older than 45 also showed a significant association with nasolacrimal duct obstruction. CONCLUSION The risk of ophthalmic complications is associated with various factors, including the administration of high I-131 doses, age of more than 45 years, and time to event within the first 12 months. Considering these conditions may help enhance patient care and prevent adverse outcomes that may limit patients' quality of life.

Abstract
BACKGROUND No widely accepted, validated instrument currently exists to measure clinical outcomes in patients who undergo dacryocystorhinostomy (DCR) for treatment of epiphora. OBJECTIVE To develop a patient-reported outcome measure applicable to this population. METHODS Psychometric evaluations, consultation with experts, and review of the literature informed item generation of a 12-question questionnaire to incorporate the most relevant symptoms experienced by patients with nasolacrimal duct obstruction. This questionnaire, known as the Tearing Assessment and Rating Scale-12 (TEARS-12), was administered to 32 patients before and after intervention, in the form of endoscopic DCR. Statistical analysis was performed to measure internal consistency, responsiveness, and test-retest reliability. RESULTS Pre-operative and post-operative TEARS-12 scores (28.2 [standard error (SE) 3.19] vs 11.8 [SE 3.25], respectively, P = 0.001) demonstrated improved patient outcome within 6 weeks following endoscopic DCR. Cronbach's alpha for the questionnaire was 0.90, indicating high overall reliability. Additionally, each question demonstrated internal reliability, with a corrected item-total correlation greater than 0.30. The intraclass correlation between the two pre-operative scores was 0.858 (P < 0.001), indicating high test-retest reliability. CONCLUSION TEARS-12 is a statistically valid, easy-to-administer instrument to measure clinical outcomes in patients who undergo endoscopic DCR.

Outcomes of Endoscopic Endonasal Dacryocystorhinostomy in Glaucoma Patients. J Pers Med 2024; 14:348. [PMID: 38672975 PMCID: PMC11050967 DOI: 10.3390/jpm14040348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 03/22/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Anti-glaucoma eye drops have been investigated due to their production of fibrotic changes on the conjunctival surface, undermining the functioning of the upper lacrimal drainage system. We aimed to assess whether these effects may impair the effectiveness of endoscopic endonasal dacryocystorhinostomy (EE-DCR). METHODS This is a single-center observational retrospective study on EE-DCR via a posterior approach. Resolution of epiphora and dacryocystitis were analyzed after 1 (T1) and 6-months (T2) from surgery. Surgical success was defined as anatomical (patency at irrigation, no recurring dacryocystitis) or complete (zeroing of Munk score). RESULTS Twenty patients (32 sides) were enrolled. Preoperatively, 93.75% (n = 30/32) presented severe (Munk 3-4) epiphora and 68.75% (n = 22/32) recurrent dacryocystitis. At T1, 50.0% (n = 16/32) were referred with residual epiphora (Munk ≥ 1) and 18.75% (n = 6/32) dacryocystitis. At T2, 31.25% (n = 10/32) still complained of epiphora (Munk ≥ 1) and 6.25% (n = 2/32) dacryocystitis. Difference of outcomes at aggregate and paired timepoints (except for T1 versus T2) resulted in statistical significance (p < 0.05). At T2, 22 (68.75%) complete, 8 (25.0%) anatomical successes and 2 (6.25%) surgical failures were observed. CONCLUSIONS Despite the chronic uptake of anti-glaucoma eye drops, EE-DCR guaranteed high rates of clinical relief from epiphora and remarkable decreases in the rates of recurrent dacryocystitis.

Enhancing Precision: A Visual Guide to Drill-Assisted External Dacryocystorhinostomy Surgery. Cureus 2024; 16:e54110. [PMID: 38500904 PMCID: PMC10948118 DOI: 10.7759/cureus.54110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/13/2024] [Indexed: 03/20/2024] Open
Abstract
This technical report aims to provide a visual guide to the drill-assisted external dacryocystorhinostomy (DCR) technique with silicone intubation. Through a step-by-step video demonstration, it addresses inherent documentation challenges and highlights crucial considerations. A critical aspect of the procedure's success lies in creating a clear space around the drilling area to prevent thermal burns and soft tissue wrapping around the burr. Additionally, it emphasizes the careful use of smaller burr diameters and the importance of drilling techniques, advocating for minimal perpendicular drilling while maintaining rotational polishing movements to minimize the risk of rapid penetration and potential nasal mucosal injury. The thermal cauterization of perforating nutrient vessels during bone drilling offers a significant advantage in reducing the risk of bleeding. A review of existing limited studies comparing drill-assisted and conventional external DCR reveals advantages such as shorter surgical duration, lower intraoperative hemorrhage rate, more regular osteotomy edges, increased ostomy patency, and potential prevention of soft tissue or mucosal injuries. Nonetheless, achieving these benefits necessitates enhanced hand and foot coordination. However, despite these benefits, a noticeable gap exists in the literature concerning comprehensive studies and comparative analyses. Furthermore, exploring the associated cost and learning curve of adopting this surgical technique is essential. This report aims to fill the existing gap in the literature and serve as a visual reference for surgeons interested in adopting drill-assisted external DCR.

Effects of Topical Anti-Glaucoma Medications on Outcomes of Endoscopic Dacryocystorhinostomy: Comparison with Age- and Sex-Matched Controls. J Clin Med 2024; 13:634. [PMID: 38276140 PMCID: PMC10817280 DOI: 10.3390/jcm13020634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 01/15/2024] [Accepted: 01/19/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND This study analyzed the effects of topical anti-glaucoma medications on the surgical outcomes of endoscopic dacryocystorhinostomy (EDCR) in nasolacrimal duct obstruction (NLDO). METHODS This retrospective study included patients who underwent EDCR for NLDO between September 2012 and April 2021. Thirty patients with topical anti-glaucoma medications and 90 age- and sex-matched controls were included. RESULTS The success rate of EDCR was higher in the control group than in the anti-glaucoma group (97.8% vs. 86.7%, p = 0.034). Univariate and multivariate logistic regression analyses identified prostaglandin analogs as the most influential risk factor for EDCR success among anti-glaucoma medication ingredients (p = 0.005). The success rate of the group containing all four anti-glaucoma medication ingredients was statistically significant (p = 0.010). The success rate was significantly different in the group of patients who used anti-glaucoma medication for >24 months (p = 0.019). When multiplying the number of drug ingredients by the duration in months, the group > 69 showed a significantly decreased success rate (p = 0.022). Multivariate logistic regression analysis identified the number of anti-glaucoma medications as the most significant risk factor for EDCR success (odds ratio, 0.437; 95% confidence interval, 0.247 to 0.772; p = 0.004). CONCLUSIONS The authors suggest that the anti-glaucoma medications might cause NLDO and increase the failure rate after EDCR. Therefore, when performing EDCR in patients using topical anti-glaucoma medications, surgeons should consider the possibility of increased recurrence after EDCR in clinical outcomes.

Abstract
Late-onset nasolacrimal duct obstruction (NLDO) as a result of inflammatory processes causing dacryo-stenosis is a common entity affecting mostly women. While a few mechanisms have been suggested as contributors to the expression of NLDO, the trigger for the inflammation remains mostly unknown. Familial predilection for this condition has not been previously reported. We present two families with multiple individuals affected with congenital or late-onset NLDO, describe the signs and symptoms of the affected individuals, and explore their medical history for any contributing factors. Family A, spanning four generations, included 7 female patients affected by late-onset NLDO. Family B, spanning two generations, included 8 individuals affected by either congenital or late-onset NLDO. This case series suggests a familial predisposition to NLDO, apparently with an autosomal dominant inheritance pattern. Further studies are needed to elucidate the molecular basis of this genetic predisposition.

Abstract
Background: Nasolacrimal duct obstruction (NLDO) is an adverse effect of high dose radioactive iodine (RAI) therapy for thyroid carcinoma. There are currently no established preventive measures. This study assesses whether preservative free artificial tears (PFATs) can decrease the 131I sodium iodide (131I) activity in the tears of patients following RAI therapy for thyroid carcinoma, and potentially serve as a preventive measure for RAI-associated NLDO. Methods: This non-randomized prospective pilot clinical trial recruited contact-lens wearing patients undergoing RAI therapy for thyroid cancer to self-administer PFATs into the right eye for four days starting on the day of RAI ingestion. Left eyes were the controls. While wearing contacts, patients self-administered PFATs per the following-Day 1: every 15 minutes for 2 hours, then every 30 minutes until bedtime, day 2: every hour for at least 12 hours, day 3: four times a day, and day 4: two times a day. Contact lenses were changed daily, and all lenses were collected one week later. Levels of 131I activity were measured by a well counter, decay-corrected, and converted to units of becquerel. Statistical analyses were performed to compare the 131I activities of the experimental and control eyes. Results: Sixteen eyes of eight patients treated with an average of 145.7 mCi (range 108-159) of 131I for papillary thyroid cancer were included. On day 1, artificial tears decreased the geometric mean 131I activity by 26% in the experimental eyes (p = 0.008). Artificial tears also decreased the geometric mean area under the curve over four days by 23% (p = 0.002). Conclusions: 131I is present in the tears following RAI therapy for thyroid carcinoma. Frequent PFATs starting on the day of RAI ingestion may decrease the level of 131I in the tears. This finding could have implications for lowering the risk of NLDO. Future multi-center clinical trials are needed to determine whether the use of artificial tears after RAI therapy may decrease the risk of NLDO. Clinical Trial Registration: NCT04327999.

Outcomes of external and endonasal dacryocystorhinostomy according to a modified Lacrimal Symptom Questionnaire (Lac-Q). MEDICAL HYPOTHESIS, DISCOVERY & INNOVATION OPHTHALMOLOGY JOURNAL 2023; 12:55-61. [PMID: 38357610 PMCID: PMC10862026 DOI: 10.51329/mehdiophthal1470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 10/14/2023] [Indexed: 02/16/2024]
Abstract
Background Nasolacrimal duct obstruction is usually treated using endoscopic or external dacryocystorhinostomy (DCR). The anatomic outcomes of both the endoscopic and external approaches are considered excellent. However, anatomic success does not translate into patient satisfaction. The current study assessed pre- and postoperative lacrimal problems using the symptom-based Lacrimal Symptom Questionnaire (Lac-Q) and investigated patient satisfaction depending on the choice of surgical technique. Methods A total of 112 eligible patients with lacrimal problems treated using external or endonasal DCR at the ophthalmology and ear, nose, and throat clinics at Skane University Hospital, Scania, Sweden, over a four-year period, were enrolled in this retrospective study. Patients were considered eligible if they experienced preoperative epiphora and had lacrimal duct stenosis. They were offered treatment using either external or endonasal DCR and were allowed to freely choose the technique. Exclusion criteria consisted of previous ipsilateral DCR, congenital NLDO, age < 18 years, presence of cancer, previous orbital trauma, or noncompliance with postoperative follow-up. After surgery, the patients were sent the Lac-Q to evaluate their lacrimal symptoms pre- and postoperatively. Complementary questions were added pertaining to the operative scar and the patients' overall satisfaction with the operation. Results In total, 67 (60%) patients with ages ranging from 18 to 88 years completed the questionnaire, 33 (49%) of whom underwent external DCR and 34 (51%) endonasal DCR. Of the 67 respondents, 51 (76%) were women and 16 (24%) were men. Patients scored preoperative lacrimal problems highly on the Lac-Q, reporting both symptomatic and social problems due to epiphora. Following surgery, the group that underwent external DCR remained home from work for 2 - 14 days (median, 3.5 days). However, 17 (52%) were retired. After the endonasal DCR, the patients remained home for 0 - 7 days (median, 2 days). Most patients were satisfied after DCR surgery, with both techniques significantly improving total, lacrimal symptom, and social impact scores (all P < 0.001). No differences in postoperative satisfaction were observed between the external DCR and endonasal DCR groups (P > 0.05). A small number of patients expressed scar-related concerns after external DCR. Conclusions The patients perceived lacrimal problems as a significant symptomatic and social burden. Postoperative satisfaction and symptom relief were good regardless of the surgical approach. Further prospective studies assessing patient satisfaction and its correlation with anatomical and functional success rates after external and endonasal DCR could provide robust, practical, real-world implications.

Use of Mitomycin C in Dacryocystorhinostomy: A Report by the American Academy of Ophthalmology. Ophthalmology 2023; 130:1212-1220. [PMID: 37656088 DOI: 10.1016/j.ophtha.2023.06.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 09/02/2023] Open
Abstract
PURPOSE To review the literature on the adjuvant use of mitomycin C (MMC) during dacryocystorhinostomy (DCR) in adults with primary nasolacrimal duct obstructions (NLDOs) to determine the efficacy in improving functional and anatomic outcomes with an acceptable level of risk. METHODS A literature search conducted in November 2020 and updated in November 2022 yielded 137 articles. Twenty-four articles met the inclusion criteria and were rated for level of evidence by the panel methodologist. Inclusion criteria required controlled studies on the effect of MMC on outcomes of external, endoscopic endonasal, or diode laser-assisted transcanalicular DCR in adults with primary acquired nasolacrimal obstruction with 6 months minimum follow-up and at least 10 participants. RESULTS Six of the 24 articles were rated level I evidence, 15 level II , and 3 level III. In primary external DCR, MMC significantly improved functional outcomes in 3 of 9 series. In primary endoscopic endonasal DCR, MMC significantly improved functional outcomes in 1 of 9 series. In revision endoscopic endonasal DCR, MMC significantly improved functional success in 1 of 3 series. The use of MMC did not improve outcomes statistically in any diode laser-assisted transcanalicular DCR studies. Concentrations of MMC ranged from 0.05 to 1 mg/ml, with 0.2 mg/ml used most frequently in 12 series, with duration of application ranging from 2 to 30 minutes. Ostium size was significantly larger in MMC groups than in control groups at 6 months after surgery in 4 of 5 reporting studies. However, these larger ostia did not confer higher functional success rates. Reporting of adverse events related to MMC were rare, with delayed cutaneous wound healing reported in 1 of 750 patients. CONCLUSIONS Intraoperative use of MMC in external and endoscopic endonasal DCR has been shown to improve functional and anatomic outcomes compared with controls in some series, but there is no agreement on the recommended concentration or application time for MMC in DCR. The data support that MMC use can result in a larger ostium size, decreased granulation tissue formation, and a decreased number of postoperative nasal debridements compared with controls, but this does not translate into improved functional success.

Abstract
Purpose Congenital nasolacrimal duct obstruction (CNLDO) is fairly common in newborns. The main aim of this cross-sectional study is to assess the preferred practice patterns of CNLDO among ophthalmologists in Jordan. Methods This cross-sectional study was conducted across all ophthalmological practices in Jordan, using convenience sampling. An online questionnaire, designed through Google Forms, was distributed through social media. The survey contained four domains: baseline characteristics of participants and the diagnosis (7 items), medical management (3 items), and surgical management (11 items) of CNLDO. Descriptive statistics were conducted using SPSS (IBM SPSS Corp, SPSS Statistics ver. 26, USA). Results Eighty-three physicians responded to the survey, with an average age of 40.6 ± 8.6. More than half of the participants (53.0%, n = 44) were general ophthalmologists. Only 37.3% of our sample (n = 31) regularly evaluated the refraction of a child presenting with epiphora suggestive of CNLDO. Criggler's nasolacrimal duct massage was recommended by 62.7% of respondents (n = 52) for up to 12 months. In addition, 72.3% of respondents (n = 60) recommended 12 months as the minimum age for primary probing of CNLDO. Silicon intubation was considered for primary probing starting at 24 months by 31.3% of ophthalmologists (n = 20). Monocanalicular stent was preferred by 42.2% of respondents (n = 27) while 31.3% (n = 20) preferred bicanalicular stent. Conclusion There is considerable variability in preferred practice patterns regarding the diagnosis and management of CNLDO in Jordan. Our findings highlight the gaps in optimum practices which need to be addressed for better management.

Abstract
In this unique cytology case of a 64-year-old diabetic male who presented with left-sided facial swelling between the ala and lateral canthus of the left eye, conventional fine-needle aspiration cytology (FNAC) was done. FNAC of the swelling showed desquamated epithelial cells from the nasolacrimal duct and abundant proteinaceous material admixed with fungal organisms like that of budding yeast forms, morphologically resembling Candida on May-Grunwald-Giemsa stain. Special stain with periodic acid-Schiff revealed positivity for budding yeast forms. In this case report, we discuss the causes and clinical effects of nasolacrimal duct obstruction, cytological diagnostic features, and microscopic recognition of fungal organisms on routine staining as well as on special fungal stains.

Comparing the success rate of external dacryocystorhinostomy with anterior flap versus flap excision in managing chronic dacryocystitis. MEDICAL HYPOTHESIS, DISCOVERY & INNOVATION OPHTHALMOLOGY JOURNAL 2023; 12:1-8.

Abstract
Background Nasolacrimal duct obstruction (NLDO) is characterized by epiphora and recurrent episodes of acute dacryocystitis. Despite the temporary effect of antibiotics in the acute phase, it is primarily managed by dacryocystorhinostomy (DCR). There is a new modification of external DCR that is performed without either anterior or posterior flaps. This study aimed to compare the outcomes of flapless and single-flap external DCR in adult patients with chronic symptomatic dacryocystitis secondary to NLDO. Methods In this retrospective, non-randomized, interventional, comparative study of patients with chronic dacryocystitis secondary to primary acquired NLDO, we compared the surgical outcomes and complication rates of flapless external DCR to those of external DCR with only anterior flap suturing. We excluded patients who declined participation and those with soft stops, nasal problems, lid margin abnormalities, lid malposition or laxity, previous lacrimal surgery, lacrimal fistula, trauma involving the lacrimal drainage system, lack of adequate follow-up, or severe septal deviation or turbinate hypertrophy. Anatomical and functional success rates were determined at the last follow-up visit and were compared. Postoperative complications were recorded and compared between groups. Results We included 53 patients with a male-to-female ratio of 16 (30.2%) to 37 (69.8%); 25 eyes underwent flapless DCR (group 1) and 28 eyes underwent anterior flap suturing DCR (group 2). The two groups had comparable demographic characteristics (all P > 0.05). Furthermore, anatomical (92.0% in group 1 and 92.9% in group 2) and functional (84.0% in group 1 and 92.9% in group 2) success rates at final follow-up were comparable between groups (both P > 0.05). At the one-month postoperative examination, premature tube extrusion was more often reported in group 1 (12.0%) compared to group 2 (7.1%). At the two-month follow-up examination, tube extrusion was noted in 4.0% in group 1 and 0.0% in group 2, yet the difference failed to attain statistical significance (P > 0.05). Conclusions We found that neither surgical method was superior in terms of anatomical or functional success rate at a maximum of one year after external DCR. Flapless DCR is a simple, effective, and reproducible alternative to the single anterior flap suturing technique for managing NLDO in adults with chronic dacryocystitis. However, further randomized clinical trials with larger sample sizes and longer follow-up periods are recommended before generalization can be justified.

Abstract
Sporotrichosis, a subacute or chronic mycosis caused by the Sporothrix schenckii complex, is commonly seen in tropical or subtropical parts of the world, especially in individuals who are in contact with cats or engage in gardening activities. Sporotrichosis generally presents with skin ulceration at the site of inoculation and follows a lymphocutaneous pattern; however, it can present in various confounding ways. Here, we present a case of disseminated sporotrichosis in an immunocompromised patient who did not seem to have any of the commonly associated risk factors and initially presented with a left nasolacrimal duct obstruction caused by lacrimal sac sporotrichosis, but then was found to have monoarticular involvement of his knee also secondary to disseminated sporotrichosis. Thorough clinical and microbiological evaluation, as well as multidisciplinary work, can lead to correct diagnosis and treatment of sporotrichosis, especially for atypical presentations in immunocompromised individuals.

(1) Background: We aim to find a novel blink parameter in nasolacrimal duct obstruction (NDO) patients and analyze parameters that could reflect subjective symptoms and objective indicators at the same time through a blink dynamic analysis. (2) Methods A retrospective study was conducted with 34 patients (48 eyes) who underwent lacrimal passage intubation (LPI) and 24 control groups (48 eyes). All patients' blink patterns were measured using an ocular surface interferometer before and after LPI, including total blink (TB) and partial blink (PB) and the blink indices blink time (BT), lid closing time (LCT), closure time (CT), lid opening time (LOT), interblink time (IBT), closing speed (CS) and opening speed (OS). The tear meniscus height (TMH) was measured, and the questionnaire "Epiphora Patient's Quality of Life (E-QOL)," which includes daily activity restriction as well as static and dynamic activities, was completed. (3) Results: Compared to CT and the ratio of CT during BT (CT/BT) in control (89.4 ± 20.0 msec, 13.16%), those in NDOs were longer (140.3 ± 92.0 msec, 20.20%) and were also related to TMH. After LPI, CT and CT/BT were recovered to 85.4 ± 22.07 msec, 13.29% (p < 0.001). CT and CT/BT showed a positive correlation with the E-QOL questionnaire score, particularly with dynamic activities. (4) Conclusions: CT and CT/BT, which are objective indicators associated with subjective symptoms of patients, are considered new blink indices for the evaluation of NDO patients with Munk's score.

Abstract
OBJECTIVE To analyze the clinical characteristics of differentiated thyroid cancer (DTC) patients with nasolacrimal duct obstruction (NLDO) after Iodine-131 (131I) therapy and provide guidance for clinical decision-making. METHODS Thirty-one DTC patients with NLDO were retrospectively enrolled from the Nuclear Medicine Department of Shanxi Bethune Hospital during follow-up of 131I therapy between June 2018 and March 2021. Eight hundred and seventy-one thyroid cancer patients during this period without NLDO after 131I therapy were enrolled as the control group. Clinical characteristics, including sex, age, dose, anti-thyroglobulin antibodies (TGAb), and metastatic lesions, were analyzed by χ2 test and logistic multifactor regression. RESULTS In the NLDO group and without NLDO group, there were statistically significant differences in gender, age, dose, and whether there was metastasis. Among the NLDO group, the proportion of women, age >55 years old, dose >5.55 GBq, and the presence of metastasis was higher, and the difference was statistically significant; There was no significant difference in the proportion of TGAb positive and negative patients based on 131I therapy (χ2 = 0.27, P = .782).Multivariate logistic regression analysis showed that sex (2.59), age (1.45), dose (2.36), and metastatic lesions (1.93) were all statistically significant influential factors of NLDO after iodine therapy. Significant differences were found in the incidence of NLDO between the number of treatment courses (χ2 = 23.541, P < .001). Prevalence rate of repeat radioiodine therapy (2 times or 3 times and more) is higher than 1 time. CONCLUSION Women patients over 55 who had metastatic lesions, and received a dose >5.55 GBq, were more likely to have NLDO. When determining therapeutic doses of 131I, doctors should weigh multiple factors and then give appropriate dosage and suggest that high risk populations be referred for appropriate ophthalmic surgical consultation, for timely diagnosis and therapy.

Endoscopic-guided diagnosis of and interventional stent placement for nasolacrimal duct obstruction in a horse. Vet Ophthalmol 2023; 26:256-261. [PMID: 37030668 DOI: 10.1111/vop.13094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 03/14/2023] [Accepted: 03/19/2023] [Indexed: 04/10/2023]
Abstract
OBJECTIVE To describe the successful use of endoscopy to visualize and place a soft canine ureteral stent to relieve a chronic nasolacrimal duct (NLD) obstruction in a horse. ANIMAL STUDIED A 7-year-old, Quarter horse gelding. PROCEDURE Under general anesthesia, retrograde nasolacrimal endoscopy was performed using an 8.5 Fr Storz Flex XC ureteroscope through the nasal punctum (NP). An obstructive web of fibrous tissue was visualized approximately 20 cm proximal to the NP. A 0.035″/150 cm hydrophilic guidewire was passed normograde from the ventral lacrimal punctum and used to puncture the stenotic tissue. Then, a 5.0Fr/70 cm open-end ureteral catheter was threaded normograde over the guidewire and NLD patency was re-established. The catheter confirmed a NLD length of 30 cm and was then removed. A 5.0Fr/22-32 cm Universa© Soft Ureteral Stent was threaded normograde over the guidewire until the loops of the stent were exposed at each end. The guidewire was removed and the stent loops were sutured in place. RESULTS The stent was withdrawn 1 month after the procedure. Telephone follow-up with the client reported significant improvement in the amount of ocular discharge and decreased sensitivity around the face and ears. CONCLUSION Endoscopy is a safe and effective procedure allowing for definitive diagnosis of NLD obstruction and to assist in interventional procedures. Placement of a canine indwelling ureteral stent seems to be an effective alternative treatment option for equine NLD obstruction compared to conventional invasive surgical procedures.

Abstract
Given the improvement in the instrument and techniques, novel surgical interventions emerged to avoid the osteotomy from the gold standard dacryocystorhinostomy (DCR) for treating primary acquired nasolacrimal duct obstruction (PANDO). This study's aim is to compare the surgical outcomes of antegrade balloon dacryocystoplasty (DCP) with pushed monocanalicular intubation (MCI) to balloon DCP alone in patients with complete PANDO. Adult patients with complete PANDO receiving balloon DCP followed by pushed MCI or balloon DCP alone from December 2014 to May 2019 were retrospectively reviewed. A total of 37 eyes of 29 patients were treated with balloon DCP with pushed MCI for 1 month, whereas 35 eyes of 28 patients were treated with balloon DCP alone. The success rates at 1 month, 3 months, and 6 months after operation were 89.2%, 73.0%, and 70.2%, respectively, in balloon DCP with MCI group, and 62.9%, 62.9%, and 60.0%, respectively, in the balloon DCP alone group. The balloon DCP with pushed MCI group had a better success rate but only reached statistical significance at 1 month postoperatively (p < 0.01). Subgroup analysis was performed based on age. The success rate in those under 65 in the combined balloon DCP with MCI group was significantly higher than in balloon DCP alone group (72.7% vs. 9.1%, p = 0.004), whereas there was no significant difference between those aged at least 65 in the combined group and the balloon DCP alone group (69.2% vs. 83.3%, p = 0.2). Conclusively, there was no significant difference in the success rate between antegrade balloon DCP with and without pushed MCI in general. Nevertheless, the former procedure was associated with significantly higher surgical success rate than the latter in younger patients.

Abstract
BACKGROUND Our study aims to compare non-invasive imaging such as topical computed tomography dacryocystography (CTD) and topical magnetic resonance dacryocystography (MRD) in patients with epiphora. PURPOSE To evaluate the practicability of topical contrast media during helical CTD and topical saline during MRD to reveal obstruction in the nasolacrimal drainage system (NLDS). MATERIAL AND METHODS Twenty participants with nasolacrimal duct obstruction were observed for two years. Ten participants underwent CTD and the other 10 participants underwent MRD. Images were analyzed by two radiologists. Participants were also asked about the level of discomfort of the contrast material versus the saline solution. RESULTS The NLDS was seen on both CTD and MRD. Very good agreement between the two observers (κ value > 0.81) was seen according to the κ statistics. CTD multiplanar and 3D images allowed for precise diagnosis of the point of obstruction whereas, the MRD did not require any contrast material and showed the point of obstruction. Saline was more comfortable for the patients than topical contrast (P < 0.05). CONCLUSION Topical CTD and MRD are non-invasive techniques that can visualize the degree and level of obstruction in the NLDS than conventional invasive cannulation dacryocystography. CTD is useful in visualizing the point of obstruction and smaller drainage structures. However, it is a source of ionizing radiation to the lens. The benefit of MRD is that it requires no contrast or radiation; however, it is poor in depicting the bone anatomy and smaller drainage structures. Finally, saline was better tolerated by patients than topical contrast.

Abstract
Down Syndrome is one of the most common chromosomal conditions in the world, affecting an estimated 1:400-1:500 births. It is a multisystem genetic disorder but has a wide range of ophthalmic findings. These include strabismus, amblyopia, accommodation defects, refractive error, eyelid abnormalities, nasolacrimal duct obstruction, nystagmus, keratoconus, cataracts, retinal abnormalities, optic nerve abnormalities, and glaucoma. These ophthalmic conditions are more prevalent in children with Down Syndrome than the general pediatric population, and without exception, early identification with thoughtful screening in this patient population can drastically improve prognosis and/or quality of life.

Abstract
Despite an obvious interest in the processes occurring in the lacrimal passages in their obstruction, there is few articles analyzing their biometric parameters. PURPOSE The study investigates the biometric characteristics of the lacrimal passages in healthy individuals and in patients with nasolacrimal duct obstruction. MATERIAL AND METHODS The study included 81 cases of partial nasolacrimal duct obstruction and 38 cases without tear drainage insufficiency. All patients underwent computed tomography with dacryocystography. Analysis of the biometric parameters involved calculation of the length, volume, and average sectional area of the nasolacrimal duct and the nasolacrimal bony canal. The ratio R4/16l was calculated (where R is the radius of the nasolacrimal duct; l is the length of the nasolacrimal duct). The normality of values was assessed using the Shapiro-Wilk test. Intergroup differences were assessed using the Mann-Whitney test and t-statistics for independent samples. Correlation analysis was performed according to the Spearman method. ROC analysis was carried out. Differences were considered significant at p≤0.05. RESULTS There were significant differences in the volume (p=0.004) and the average sectional area of the nasolacrimal duct (p=0.014), as well as in the length of the nasolacrimal canal (p=0.034). Relationships were established between the age of patients without tear drainage insufficiency and the length of the nasolacrimal canal (p=0.042); the length of the nasolacrimal canal and the volume of the nasolacrimal duct (p=0.034), as well as the volume of the nasolacrimal duct and the nasolacrimal canal in partial nasolacrimal duct obstruction (p=0.017). The AUC of the R4/16l ratio in the ROC analysis was 0.653 (p=0.007). CONCLUSION In addition to the obvious differences, it was found that the length of the nasolacrimal bony canal significantly differed in the subjects of both study groups. We considered the tear ducts as a hydrodynamic system obeying Poiseuille's law, so we calculated the ratio R4/16l. The value of this ratio varied (p=0.016), and the ROC analysis showed high sensitivity and specificity of the criterion. This makes it possible to use this ratio as a diagnostic criterion for partial nasolacrimal duct obstruction.

Abstract
OBJECTIVE To identify factors associated with radioactive iodine (RAI)-acquired nasolacrimal duct obstruction (NLDO). METHODS Retrospective chart review and telephone surveys of patients who received RAI therapy for thyroid carcinoma at an academic institution were conducted. Telephone surveys were used to screen for post-RAI NLDO diagnoses. Databases were reviewed for documented NLDO, demographics, RAI dose, total number of RAI treatments, and sialadenitis. Routine post-RAI whole-body scintigraphy (WBS) images were analyzed for the presence or absence of 131I sodium iodide (I-131) in the nasolacrimal duct. Intranasal I-131 activity was graded as none, low, moderate, and high; those with moderate or high activity were considered to have "increased" activity. Logistic and ordinal logistic regression models were used to evaluate the associations with NLDO while adjusting for I-131 dose. RESULTS Of the 209 patients who completed the survey, 15 (7%) had NLDO diagnoses. Increased intranasal I-131 activity on WBS, presence of nasolacrimal I-131 WBS activity, presence of documented post-RAI sialadenitis, and history of >1 RAI treatment were associated with the development of NLDO from univariate analyses (P ≤ .013). After adjusting for the administered dose of I-131, the presence of sialadenitis and nasolacrimal I-131 activity on WBS were the remaining 2 factors significantly associated with NLDO development (P < .001 and P = .01, respectively). CONCLUSIONS The presence of sialadenitis and nasolacrimal I-131 activity on WBS are I-131 dose-independent correlative factors for RAI-associated NLDO. Patients with these characteristics should be counseled on their increased risk of NLDO after RAI therapy for thyroid carcinoma.

Abstract
As a rare and often misdiagnosed disease of the lacrimal apparatus, only limited data exist on long-term outcomes of surgical methods for the treatment of primary canaliculitis. The aim of this study was to evaluate canaliculotomy with silicone tube intubation (STI) as a surgical procedure for canaliculitis in a long-term follow-up setting. A total of 25 eyes of 25 patients with canaliculitis treated with canaliculotomy and STI at the University of Muenster Medical Center, Germany, from 2015 to 2021 were included in this study. Data analysis involved clinical symptoms, complications, duration of STI and rate of recurrence. Mean patient age was 63.7 ± 17.2 years. After a follow-up time of 3.7 ± 1.5 years, 88% of cases showed no recurrence of inflammation. The mean duration of STI was 5.8 ± 3.4 months. Complications such as post-operative hemorrhage, spread of infection, obstruction of the canaliculus or migration of the STI were not observed in any of the patients. However, tube dislocation occurred in four cases, a pyogenic granuloma in two cases and a fistula formation in one case. The management of canaliculitis by canaliculotomy with STI showed very good postoperative outcomes and low complication rates in the long-term and can therefore be considered a safe and successful surgical approach.

Abstract
Nasolacrimal duct obstruction (NLDO) is a rare complication after radioiodine therapy and may cause false positive 131I uptake at the point of obstruction in 131I whole body scan. Here, we report a 59-year-old female patient with papillary thyroid cancer treated with total thyroidectomy followed by 131I therapy. 131I whole body scan revealed focal uptake in the head. Single photon emission computed tomography/computed tomography (CT) showed focal uptake at the right proximal nasolacrimal duct. The ophthalmologic examination and the diagnostic maxillofacial CT confirmed the diagnosis of NLDO.

Abstract
PURPOSE To determine the effect of unilateral primary acquired nasolacrimal obstruction (PANDO) on ocular surface parameters in PANDOeyes and fellow eyes and changes in these parameters after dacryocystorhinostomy. METHODS Tear osmolarity, tear break-up time (TBUT), Schirmer's test, Meibomian gland score, and Lissamine Green staining of PANDO eyes and fellow eyes were measured preoperatively and postoperatively at Day 15, 1 month, and 3 months. Lacrimal irrigation and epiphora symptomatology were evaluated at all follow-up visits, and patients who did not meet surgical success criteria were excluded from the study. RESULTS Twenty-nine patients who underwent successful dacryocystorhinostomy surgery were included in the study. Preoperative and postoperative Day 15 Schirmer (p = .019, p = .001) and TBUT (p = .039, p = .043) were significantly lower in the fellow eye compared to PANDO eyes. The differences observed between PANDO eyes and fellow eyes in all other parameters were not significant (p > .05). Preoperatively PANDO eye parameters were normal, whereas TBUT (7.59 ± 5.39 s) and tear osmolarity (308.59 ± 17.32 mOsm/L) values of the fellow eye may be indicative of tear film instability. TBUT and tear osmolarity of the fellow eye showed significant improvement 3 months postoperatively compared to preoperative values (p = .010; p = .027 respectively). CONCLUSION Schirmer and TBUT values of the fellow eye were significantly lower than PANDO eyes preoperatively, one month after surgery there was no significant difference. TBUT and tear osmolarity of the fellow eyes may be indicative of tear instability preoperatively with improvement 3 months after dacryocystorhinostomy.

Abstract
Samter's triad, also known as aspirin-exacerbated respiratory disease, is characterized by nasal polyposis, bronchial asthma, and aspirin intolerance. Here, we present a case of a 36-year-old woman with a history of Samter's triad and recurrent dacryocystitis. After combined dacryocystorhinostomy and endoscopic sinus surgery, pathological specimens of the lacrimal sac showed respiratory fibrosis with chronic inflammation and eosinophilic infiltration. Our case demonstrates that Samter's triad is a potential etiology for inflammatory nasolacrimal duct obstruction.

Abstract
PURPOSE To report an unusual case of an ectopic lacrimal fistula in a setting of a naso-orbito-ethmoid fracture. CASE REPORT The present case demonstrates a right-sided ectopic lacrimal fistula just below the glabella on the contralateral side on the outer edge of the midline. CT-Dacryocystography demonstrated a large dilated right lacrimal sac with a partly sequestered fundus traversing through the frontal process of the maxilla and frontal bone, close to the skull base and communicating with the fistula. The connection of the fistula with the sac was severed at the superior-most point, and the long fistulous tract was removed using external and endoscopic approaches, followed by endocautery and subsequent dacryocystorhinostomy. Post-operatively, the fistulous opening healed, ostium score was FICI grade 5, and the patient was asymptomatic. CONCLUSION The case demonstrates multiple surgical challenges while managing an ectopic fistula with a long fistulous tract traversing several bony structures.

Abstract
BACKGROUND This diagnostic study aimed to assess degree of agreement between dacryoscintigraphy and dacryocystography as supporting examinations in patients with primary acquired nasolacrimal duct obstruction (PANDO). Patients with PANDO who complained of epiphora and visited our outpatient clinic were subsequently sent for dacryoscintigraphy and dacryocystography examinations. Side effects and convenience of both examinations were assessed by observation and questionnaire. MATERIAL AND METHODS Through irrigation and probing, there were 47 out of 62 eyes were found with PANDO. As much as 87.1% subjects were female, with mostly (74.2%) aged > 40 years old. With dacryoscintigraphy, time needed to reach sac was 0 minutes, 5 minutes (duct), and 12.5 minutes (nasal cavity). RESULTS Degree of agreement between both examinations was 83.8% to determine obstruction and 70.9% to locate obstruction. There were 22 subjects complained about pain in dacryocystography examination while none with dacryoscintigraphy (p < 0.005). Sixteen subjects feel dacryoscintigraphy examination was more convenient, eleven subjects feel dacryocystohraphy was more convenient, while 4 subjects feel the two examinations were similar. CONCLUSIONS Even though dacryocystography examination was considered more painful than dacryoscintigraphy, both examinations had high convenience level for patients. Dacryoscintigraphy and dacryocystography also had a good agreement in detecting and locating obstruction in PANDO.

Abstract
Background: The Caldwell-Luc (CL) procedure, an outdated operative procedure that is used to treat inflammatory sinus diseases, is rarely performed presently. However, physicians may encounter patients with a history of CL surgery who develop considerable postoperative changes that may lead to diagnostic confusion in imaging evaluation; increase the difficulty of future surgery, such as sinonasal surgery; and increase the incidence of future intraoperative complications. Case summary: A 67-year-old man with a surgical history of chronic sinusitis reported epiphora of the left eye for five years. Balloon dacryocystoplasty was attempted but failed. Endo-DCR (Endoscopic dacryocystorhinostomy) was indicated; however, preoperative CT (computed tomography) imaging and nasal endoscopic examination showed sinonasal anomalies and the loss of internal landmarks for localizing the lacrimal sac. Preoperative CT results indicated previous CL surgery. Endo-DCR was performed with the aid of nasal forceps and a 20-gauge vitreoretinal fiberoptic endoilluminator. A six-month follow-up revealed the complete resolution of symptoms and no signs of recurrence. Conclusions: Epiphora might be a delayed complication of the CL procedure. Before performing endo-DCR, ophthalmologists should be familiar with the sinonasal anatomy and carefully assess preoperative imaging to identify anatomical variations. Nasal forceps and transcanalicular illumination can assist in determining the precise location of the lacrimal sac during endo-DCR.

Abstract
PURPOSE To investigate the prevalence of dry eye symptoms after successful dacryocystorhinostomy and explore the potential risk factors. Methods: This cross-sectional study included 565 patients with lacrimal passage obstruction (LPO) who underwent external dacryocystorhinostomy. Ocular Surface Disease Index (OSDI) total score of 13 or more was regarded as presence of dry eye symptoms. OSDI total score greater than 22 combined with self-reported dry eye was defined as symptomatic dry eye. Logistic regression and linear regression were used to examine the associations between OSDI scores and its potentially predictive factors. Results: Of the 565 patients, 344 completed the questionnaire, among which 101(29.4%) patients presented with dry eye symptoms, including 53(15.4%) mild, 14(4.1%) moderate and 34(9.9%) severe, and 48(14.0%) patients can be defined as symptomatic dry eye. Univariate logistic regression revealed that age, educational levels, income levels, and hypertension were significantly correlated with the presence of dry eye symptoms (P < 0.05). After multivariate adjustment, lower income levels were found significantly associated with dry eye symptoms (P < 0.05). Univariate linear regression demonstrated that age, lower educational levels, surgery history, and hypertension were significantly associated with OSDI total score (P = 0.037, 0.012, 0.022, 0.029 respectively). Multivariate stepwise linear regression manifested that educational levels and the surgery history influenced the OSDI total score mostly (P = 0.021, 0.036 respectively). Conclusions: Dry eye problem of LPO patients after successful dacryocystorhinostomy cannot be ignored. In the preoperative evaluation, we should pay special attention to the elderly patients with lower educational levels, lower income levels or systemic diseases.

Iatrogenic nasolacrimal duct obstruction after adnexal intervention: An avoidable consequence. Oman J Ophthalmol 2021; 14:157-161. [PMID: 34880576 PMCID: PMC8597813 DOI: 10.4103/ojo.ojo_462_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2020] [Revised: 06/13/2021] [Accepted: 07/01/2021] [Indexed: 11/26/2022] Open
Abstract
PURPOSE: Isolated cases of nasolacrimal duct obstruction (NLDO) secondary to rhino-orbito-facial reconstructive surgeries have been reported previously. We report the clinical profiles and management outcomes of a series of patients with iatrogenic INDO. MATERIALS AND METHODS: Case records of all patients who presented with secondary NLDO over 5 years were retrospectively analyzed. The case series included seven patients with NLDO secondary to orbito-facial surgeries. RESULTS: The study included six males and one female patient with a mean age of 29 ± 12.58 years. All the patients had a history of road traffic accidents following which they underwent an open reduction and internal fixation by maxilla-facial surgeons. All of them presented to the Ophthalmology outpatient department with epiphora following the surgical intervention. Imaging revealed the implants were responsible for obstructing the nasolacrimal ducts in all seven cases. Five patients underwent external dacryocystorhinostomy while dacryocystectomy was performed in two. Implant removal was necessary for five patients without any compromise on the structural integrity of the orbital walls. CONCLUSION: Precise knowledge of the orbital anatomy, especially that of the lacrimal drainage system is imperative for surgeons performing surgeries in the midface area. A multidisciplinary approach and inclusion of surgeons trained in lacrimal surgeries can prevent such avoidable complications.

Abstract
OBJECTIVES To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. METHODS The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. RESULTS Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III (P = .4). The most common reason for revision surgery was stenosis of the neo-ostium (n = 8), followed by granulation tissue formation (n = 5) and synechia formation (n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation (P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates (P = .79 and P = .76, respectively). CONCLUSION The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.

Abstract
For the past 80 years, radioiodine (131I) has been used to ablate thyroid tissue not removed by surgery or to treat differentiated thyroid cancer that has metastasized to other parts of the body. However, the Na+/I- symporter (NIS), which mediates active iodide uptake into thyroid follicular cells, is also expressed in several non-thyroidal tissues. This NIS expression permits 131I accumulation and radiation damage in these non-target tissues, which accounts for the adverse effects of radioiodine therapy. We will review the data regarding the expression, function, and regulation of NIS in non-thyroidal tissues and explain the seemingly paradoxical adverse effects induced by 131I, the self-limited gastrointestinal adverse effects in contrast to the permanent salivary dysfunction that is seen after 131I therapy. We propose that prospective studies are needed to uncover the time-course of pathological processes underlying development and progression or ultimate resolution of 131I-induced salivary ductal obstruction and nasolacrimal duct obstruction. Finally, preventive measures and early therapeutic interventions that can be applied potentially to eliminate or alleviate long-term radioiodine adverse effects will be discussed.

Abstract
Objectives: To identify microbiological growth on bicanalicular silicone tubes (BST) placed during dacryocystorhinostomy (DCR) surgery and to analyze the association between culture results and surgical outcomes and BST removal time. Materials and Methods: A total of 80 lacrimal drainage systems of 68 patients who had external DCR with bicanalicular silicone intubation were included the study. Twenty-five tubes (31.3%) were removed up to 8 weeks, 28 tubes (35.0%) were removed between 9 and 11 weeks, and the remaining 27 tubes (33.7%) were removed 12 weeks or more after surgery. The tubes were transferred to Stuart medium and sent for microbiologic examination. The disc diffusion method was used to determine antibiotic resistance. Results: Culture positivity was observed for 96.2% of the tubes. Among a total of 109 isolates, 63 were gram-positive bacteria (57.8%), 37 were gram-negative bacteria (34%), and 9 were fungi (8.2%). The most commonly isolated gram-positive and gram-negative bacteria were Staphylococcus aureus (66.6%) and Enterobacter spp. (29.7%), respectively. Penicillin, clindamycin, erythromycin, and tetracycline resistances were higher among gram-positive pathogens. Cephalothin, amoxicillin-clavulanic acid, and ampicillin resistances were higher among gram-negative pathogens. There was no significant difference in terms of the microbiological profile between the three groups of removed tubes. Haemophilus influenzae was isolated at a significantly higher rate in patients with surgical failure (p=0.04). Conclusion: Although a variety of agents were isolated from removed BST, gram-positive organisms were more frequent than gramnegatives and fungi. S. aureus and Enterobacter were the most common gram-positive and gram-negative isolates. Later BST removal was associated with the isolation of significantly more bacterial strains per tube. There was no correlation between multiple infections and surgical failure. H. influenzae was more common in failed DCR cases.

Abstract
Objective To evaluate medium/long term outcomes and patient satisfaction through relief of symptoms and improved quality of life (QoL) after Jones tube conjunctivodacryocystorhinostomy (JT-CDCR) using the Naso Lacrimal Duct Obstruction symptom-score (NLDO-SS). Methods We conducted a retrospective, non-comparative, multicentric study including patients with complete obstruction of the superior and inferior proximal lacrimal drainage system. All patients underwent JT-CDCR, and the patency of the tube was evaluated with saline irrigation and endoscopic examination. We assessed patient satisfaction and quality of life administering the NLDO-SS. Results We enrolled 16 patients, for a total of 21 eyes operated. The success rate for procedures was 81%. The success rate for single parameters was globally 95.9%; if considered separately, ocular symptoms and nasal symptoms were respectively 94.3% and 100%. Conclusions JT-CDCR was a reliable procedure, able to solve symptoms in a majority of patients and guaranteed a good quality of life over a long period of time.

Abstract
OBJECTIVE This study was performed to determine the conjunctival microbiota of Persian cats with and without nasolacrimal duct obstruction (NLDO). ANIMALS STUDIED Twenty-five Persian cats: 15 with bilateral NLDO (Group A) and 10 with no NLDO (Group B). PROCEDURES All fifty eyes were assessed. Sterile swab applicators were used for the collection of specimens, which were cultured. PCR was performed on conjunctival swab and blood samples for the detection of Mycoplasma spp. and feline herpesvirus 1(FHV-1), respectively. RESULTS FHV-1 was detected in two cats in Group A. Twelve eyes from Group A and four from Group B were Mycoplasma spp. positive based on the PCR results. Moreover, fungal culture was positive in six eyes from Group A and three eyes from Group B. The dominant fungus isolated was Aspergillus spp. (6 out of 11 fungal isolates). Other isolated fungi were Alternaria spp. and Cladosporidium spp. Twenty-three eyes had positive bacterial culture in Group A, while twelve eyes were positive in Group B. The most commonly isolated bacteria were Staphylococcus epidermidis (15 out of 38 bacterial isolates). β-hemolytic Streptococcus spp., Corynebacterium spp., and Staphylococcus aureus were isolated in similar proportions in both groups. Escherichia coli was also present in both groups. CONCLUSIONS Results of this study revealed same isolated fungal and bacterial spp. and in similar proportions in Persian cats with and without NLDO.

Abstract
OBJECTIVE To explore the clinical effectiveness and value of lacrimal duct endoscopy in lacrimal canaliculitis and nasolacrimal duct obstruction diseases. METHODS We retrospectively analyzed 241 patients with lacrimal canaliculitis and nasolacrimal duct obstructions admitted to our hospital from January 2019 to June 2020. Among them, 165 patients underwent routine diagnosis and treatment and 76 patients underwent lacrimal duct endoscopy. The propensity score matching 1:1 nearest neighbor matching method was used to match 50 patients from each of the two methods to create a control group and an experimental group, respectively. We compared the two groups' effective treatment rates, incidences of adverse reactions, diagnostic accuracy, and IL-6, IL-8, and CRP expression levels. RESULTS in contrast with the control group, we observed a significantly higher effective treatment rate in the experimental group (P<0.05). The experimental group had a significantly better reactions rate than the control group (P<0.05). In terms of the diagnostic accuracy rate, the experimental group's results were much better (P<0.05). The IL-6, IL-8, and CRP expression levels in the experimental group were much lower in the comparison with the control group (P<0.05). CONCLUSION Lacrimal duct endoscopic diagnosis and treatment can significantly enhance the treatment efficiency and diagnostic accuracy in lacrimal canaliculitis and nasolacrimal duct obstruction patients and can help reduce adverse reactions and the IL-6, IL-8, and CRP expression levels during the treatment. Therefore, lacrimal duct endoscopy has a high clinical effectiveness in lacrimal canaliculitis and nasolacrimal duct obstruction patients.

Abstract
Distal acquired lacrimal obstruction is a common adulthood pathology whose primary treatment is represented by EXT-DCR and END-DCR. When considering their influencing factors, the role of the type of anaesthesia applied during these surgeries has a major role. The aim of this study is to systematically analyse the influence of general and local/regional anaesthesia on the final success rates of EXT-DCR and END-DCR. Primary EXT-DCR and END-DCR articles published later than 2000 with at least 50 single clinician procedures were selected. Exclusion criteria included acute dacryocystitis, tumours, studies focussing on revision surgeries, surgeries with adjunctive procedures, not clearly demarcated surgeons, mixed cohort study of acquired and congenital disorders. This systematic review was conducted in accordance with MOOSE guidelines; where feasible, a meta-analysis of the collected results was conducted. As a result, 11,445 articles were selected of which 2741 were examined after screening, and 16 included after full text review (0.6% of the initial papers). Among all papers included, the number of EXT-DCR was not enough to provide a solid analysis of the effect of anaesthesia; conversely, a significant difference of success rate was noted between local anaesthesia + sedation (85.1%, IC 77.8%-90.4%), and general anaesthesia (90.8%, IC 88.8%-92.4%) in END-DCR (p = 0.048). In conclusion, END-DCR performed with general anaesthesia should be considered as the solution of choice; however, local anaesthesia, eventually associated with a sedation, can be used as an alternative in selected cases. No meaningful conclusions could be drawn for EXT-DCR, due to the lack of data.

Abstract
RATIONALE Ectopic tooth is tooth erupting out of normal anatomical position. Ectopic tooth can occur in different positions, such as maxillary sinus and nasal cavity. In this article, we present a rare case of an ectopic tooth with a dentigerous cyst in the maxillary sinus compressing the nasolacrimal canal. PATIENT CONCERNS An 8-year-old girl presented with a 2-month history of spontaneous lacrimation in her right eye. When she wept, more tear shed from her right eye than that from the left one. Computed tomographic (CT) imaging showed a huge low-density image containing a tooth in the maxillary sinus in her right maxilla; the right nasolacrimal canal vanished due to the compression of the ectopic tooth. DIAGNOSES Ectopic tooth with dentigerous cyst of right maxilla, and obstruction of nasolacrimal duct. INTERVENTIONS The patient underwent nasal endoscopic maxillary sinus cystectomy. OUTCOMES The patient recovered well after cystectomy and has been symptom-free. LESSONS The unique finding is that this is the first report about ectopic tooth compressing the nasolacrimal canal and inducing spontaneous lacrimation. Treatment: aspect: surgery under endoscope is a minimally invasive approach to ectopic tooth.

Abstract
PURPOSE To compare matrix metalloproteinase-9 (MMP-9) point-of-care immunoassay (InflammaDry) results before and after dacryocystorhinostomy (DCR) in patients with nasolacrimal duct (NLD) obstruction. METHODS Thirty-eight eyes of 38 patients who were diagnosed with unilateral NLD obstruction were treated with endoscopic DCR. Treatment response was monitored using InflammaDry test, tear meniscus height was measured by slit-lamp microscopy, and tear meniscus parameters (tear meniscus height, depth, and area) were measured by anterior segment optical coherence tomography at baseline and at 1 month after surgery. RESULTS In 38 patients, the positive percentage of MMP-9 in diseased eyes was 100% (38 eyes), much higher than that in healthy fellow eyes (13.2%, 5 of 38 eyes) at baseline (p<0.001, χ2 test test). MMP-9 levels before and after surgery were significantly different (p<0.001), and MMP-9-positive eyes showed a significant improvement in MMP-9 grade after surgery (p< 0.0001; generalized McNemar test). Furthermore, other clinical parameters (tear meniscus area, tear meniscus height, and tear meniscus depth) showed a general improvement. CONCLUSION The concentration of MMP-9 increased in the tears of patients' eyes with NLD obstruction compared to the contralateral healthy eyes. These abnormal findings showed a significant improvement after DCR. The improvement of postoperative MMP-9 expression might be because of the improvement of tear retention.

Abstract
PURPOSE To evaluate the various surgical modalities of congenital lacrimal fistula and assess the mutual effect of lacrimal fistula and lacrimal drainage abnormality on the individual surgical outcomes. METHODS In this retrospective cohort and case-control study, 74 eyes from 63 patients with lacrimal fistula who underwent surgical management between 2000 and 2015 at three medical centers were enrolled. The data collected included sex, age, preoperative symptoms, presence of concurrent lacrimal drainage abnormality, surgical methods, and surgical outcomes. The main outcome measures were treatment outcomes based on lacrimal drainage patency and symptom improvement, surgical outcome of fistulectomy according to the presence of lacrimal drainage abnormality, and surgical outcome of lacrimal drainage abnormality according to the presence of fistula. RESULTS The mean age at the time of surgery was 9.2 (SD, ±8.8) years and the mean follow-up duration was 14.4 (SD, ±19.5) months. All eyes (37/37) with fistula without lacrimal drainage abnormality demonstrated surgical success after simple fistulectomy. Patients with concurrent lacrimal drainage abnormalities showed more frequent surgical failure than those with fistula alone (p = 0.009). However, the presence of fistula did not affect the outcomes of surgery for lacrimal drainage abnormality (p = 0.179). CONCLUSION Simple fistulectomy is sufficient for sole asymptomatic or pauci-symptomatic lacrimal fistula. Symptomatic fistula as well as those accompanied with lacrimal drainage abnormality underwent fistulectomy and lacrimal drainage system surgery. Patients with accompanying lacrimal drainage system abnormalities showed less favorable outcomes. Meticulous preoperative examination of the lacrimal drainage system is critical for surgical planning and prognosis prediction.

Office- or Facility-Based Probing for Congenital Nasolacrimal Duct Obstruction: A Report by the American Academy of Ophthalmology. Ophthalmology 2020; 128:920-927.

Abstract
PURPOSE To review the published literature assessing the efficacy and safety of in-office probing compared with facility-based probing to treat congenital nasolacrimal duct obstruction (NLDO). METHODS Literature searches were conducted in March 2020 in the PubMed database with no date restrictions and limited to studies published in English and in the Cochrane Library database with no restrictions. The combined searches yielded 281 citations. Of these, 21 articles were deemed appropriate for inclusion in this assessment and assigned a level of evidence rating by the panel methodologist. Four articles were rated level I, 2 articles were rated level II, and 15 articles were rated level III. RESULTS Treatments consisted of observation, in-office nasolacrimal probing, or facility-based nasolacrimal probing. Success rates and complications or recurrences were recorded from 1 week to 6 months after surgery. Complete resolution of symptoms after surgery ranged from 66% to 95.6% for office-based procedures versus 50% to 97.7% for facility-based procedures. Level I evidence indicated that 66% of cases spontaneously resolved after 6 months of observation in infants between 6 and 10 months of age. Success rates for in-office probing were lower for bilateral than for unilateral NLDO (67% vs. 82%), whereas success rates were high in both unilateral (83%) and bilateral (82%) patients who underwent facility-based probing after 6 months of observation. Cost data did not indicate a definitive cost savings of either treatment method ($562 for in-office vs. $701 for facility-based, depending on cost models predicting spontaneous resolution rates at different ages). No serious adverse events with treatment or anesthesia were reported for either treatment method. CONCLUSIONS Evidence supports the efficacy and safety of both in-office and facility-based surgery for congenital NLDO. However, treating bilateral NLDO in a facility setting may be better. Because a significant percentage of children achieved resolution spontaneously before 12 months of age, deferring treatment until 12 to 18 months of age is a reasonable option. Additional research may address symptom burden on families and the impact of anesthesia and emotional trauma of nonsedated office probings on patients and may explore further the cost of treatment for each treatment method.

Abstract
Tsukamurella pulmonis (Actinobacteria), a Gram-positive, obligate aerobic and weakly or variably acid-fast bacterium, is an opportunistic pathogen. Here we report two cases of conjunctivitis caused by T. pulmonis. Both patients had a previous history of nasolacrimal duct obstruction (NLDO). Isolation of T. pulmonis was performed on chocolate, tryptic soy blood and Columbia nalidixic agars. After 24 h of incubation, odourless, white-greyish, membrane-like colonies were observed. The VITEK-2 bacterial identifier system failed to identify the species, while Vitek-MS matrix-assisted laser desorption ionization time-of-flight technology, successfully identified the isolate from case 2 but not from case 1. Final identification was verified using 16S rRNA gene sequencing. An antibiogram was performed and according to the results cefazoline in addition to vancomycin eye drops for 5 days, were suggested as a treatment in case 1. In case 2 the infection was ended without treatment. This is the first report of Tsukamurella as a pathogen that causes conjunctivitis in patients with NLDO.

[PMID: 32638550 DOI: 10.1111/coa.13606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 06/04/2020] [Accepted: 06/14/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVES The objective of this study was to perform translation, cross-cultural adaptation and validation of the Lithuanian version of specific nasolacrimal duct obstruction symptom scoring (NLDO-SS) questionnaire and to evaluate short- and long-term results of endoscopic endonasal dacryocystorhinostomy (EN-DCRS) procedure. DESIGN, SETTING, PARTICIPANTS Permission for questionnaire translation, cross-cultural adaptation and validation was obtained from the authors of the original questionnaire. Translation, validation and cross-cultural adaptation were carried out according to generally accepted methodology. Validation study of the Lithuanian version of NLDO-SS (L-NLDO-SS) was performed, and short- and long-term results of EN-DCRS procedure were evaluated according to symptoms. In total, 44 patients were evaluated 2 weeks before the surgical intervention, a day before the surgery and 41 patients 2 months after the surgery, and again 10 months later. MAIN OUTCOME MEASURES We analysed the internal consistency and test-retest reliability of the L-NLDO-SS questionnaire. Cronbach's alpha was used to represent and evaluate internal consistency for ordinal responses. Validity was assessed by comparing scores between a control group of volunteers without NLDO and the NLDO group using Mann-Whitney test. To test the limiting score on which the sensitivity and specificity curves cross in identifying patients with NLDO, receiver operating characteristic (ROC) curve analysis was used. The pre- and post-operative scores were compared using the paired t-test. RESULTS The results showed an acceptable internal consistency of L-NLDO-SS questionnaire, with Cronbach's alpha-.73 in the initial test group and .71 in the retest group. Pearson's correlation coefficient was .94 (P < .001), revealing good correlation between the initial scores and the retest scores. Our sample of healthy individuals had a mean L-NLDO-SS score of 11.42 (±12.69) points, and patients being scheduled for EN-DCRS had a mean L-NLDO-SS score of 27.45 (±9.81) points. Post-operatively mean L-NLDO-SS scores improved from 27.45 (±9.81) points to 4.45 (±6.29) points in the short term and to 5.83 (±4.17) in the long term, demonstrating the statistically significant responsiveness of the instrument over both timescales. CONCLUSIONS Lithuanian version of NLDO-SS questionnaire is a valid instrument for assessing patients with NLDO in the Lithuanian population. It demonstrated good internal consistency, reproducibility, validity and responsiveness.

3D morphological classification of the nasolacrimal duct: Anatomical study for planning treatment of tear drainage obstruction. Clin Anat 2020; 34:624-633. [PMID: 32889737 DOI: 10.1002/ca.23678] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/12/2020] [Accepted: 08/26/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND The purpose of this study is to analyze and classify morphological features of the nasolacrimal duct (NLD) through 3D reconstruction to help understand the causes and treatment of NLD obstruction. METHODS In this study, we included 63 males and 55 females who underwent autopsy without NLD obstruction with ages ranging from 20 to 78 years. The NLD was defined from the lacrimal fossa to the opening of the BNLD to the inferior meatus, and all continuous CT images showing the NLD were selected. Segmentation was performed semi-automatically, and the reconstruction and measurement of NLD was performed using the Mimics program. RESULTS Overall NLD length, bony nasolacrimal duct (BNLD) length, anteroposterior and transverse diameters at the entrance to the BNLD, anteroposterior and transverse smallest diameters of the BNLD, BNLD volume, and lacrimal sac BNLD angle were significantly higher in males than females (p < .05). BNLD direction in the coronal plane was slightly more likely to be inward. The most common type in both sexes was cylinder type (42.0%), males were more likely to have lower-thicker types (34.1%), and females more likely to have upper-thicker types (22.7%). CONCLUSION There were sex differences in NLD measurements, and females had significantly smaller NLDs. These results may partially explain the increased prevalence of primary acquired NLD obstruction in females. The BNLD tends toward the midline, and inclines posteriorly.

A case of endonasal balloon-assisted dacryoplasty after failure of endonasal dacryocystorhinostomy. Clin Case Rep 2020; 8:1605-1609. [PMID: 32983459 PMCID: PMC7495747 DOI: 10.1002/ccr3.2956] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 04/13/2020] [Accepted: 04/24/2020] [Indexed: 11/24/2022] Open
Abstract
Endonasal balloon-assisted dacryoplasty is a minimally invasive technique that uses a high-pressure balloon catheter introduced into the lacrimal pathway through the nasal fossa into the neorhinostomy to treat recurrent epiphora after primary dacryocystorhinostomy. This procedure can be considered to be a reliable technique in patients unfit for general anesthesia.

Success of endoscopic dacryocystorhinostomy with or without stents: systematic review and meta-analysis. Orbit 2020; 39:258-265. [PMID: 31662017 DOI: 10.1080/01676830.2019.1677726] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2019] [Accepted: 09/30/2019] [Indexed: 05/28/2023]
Abstract
PURPOSE To evaluate the effect of stents on the success of endoscopic dacryocystorhinostomy (DCR-EN) for treating primary acquired nasolacrimal duct obstruction (NLDO). METHOD A systematic review of randomized clinical trials of DCR-EN for NLDO comparing outcomes of surgeries performed with and without the use of bicanalicular stents and the complications associated with each procedure. Two authors independently searched six databases (Scopus, PubMed, EMBASE, Google Scholar, Cochrane Central Register of Controlled Trials, and Web of Science) up to May 2019. Statistical analysis and meta-analysis were performed using RevMan 5.3 software provided by the Cochrane Collaboration. RESULTS Twelve studies involving 997 surgeries were included in this systematic review. The meta-analysis using a fixed-effects model showed a 94% success rate with stents versus 90.6% without stent. Although stent use favors greater success of DCR-EN, the confidence interval (CI) was wide and very close to nullity line (1.01), decreasing the strength of the recommendation for stent (odds ratio: 1.62, 95% CI: 1.01-2.59, I 2 = 0%). Meta-analysis of the adverse effects was not possible. A descriptive analysis was performed of the general complications related to the stents. CONCLUSIONS There is evidence that the use of bicanalicular stents slightly improves the success rate of DCR-EN, but the quality of evidence is low. Future prospective, randomized trials enrolling larger sample sizes may provide stronger evidence to determine whether the stent use influences the success of primary acquired DCR-EN.

Abstract
OBJECTIVE Endoscopic endonasal balloon-assisted dacryoplasty is a minimally-invasive surgical procedure that can be used in recurrent epiphora, a common pathology in both adulthood and childhood. STUDY DESIGN/SETTINGS We present a retrospective case series of eight patients who underwent trans-nasal balloon-assisted dacryoplasty after a failed external or endoscopic dacryocystorhinostomy, from March 2019 to January 2020, at the Department of Otolaryngology, San Raffaele Hospital, Milan, Italy. SUBJECTS AND METHODS All patients underwent routine preoperative work-up including fluorescein test (Jones test I-II), probing and irrigation of the lacrimal pathway and nasal endoscopy. Because of the recurrent nature of the pathology, pre-operatory computed tomography scan or dacryocystography was not performed. The surgical procedure was based on enlargement of the stenotic neorhinostomy created by primary dacryocystorhinostomy through the use of a high-pressure balloon catheter. Anatomical success was defined as a patent ostium on irrigation, whereas functional success was defined as free lacrimal flow on functional test and resolution of epiphora. RESULTS Anatomic and functional success was achieved in 100% of patients. Operative time ranged from 9 to 22 min (mean 16 min). No significant complications were reported. CONCLUSION Our results indicate that trans-nasal balloon-assisted dacryoplasty can be considered as a safe and reliable surgical approach after a failed primary dacryocystorhinostomy. The shorter surgical time and reduced post-operative complication rates are the main advantages of this procedure.

Long-term outcome of lacrimal stent intubation for complete acquired lacrimal drainage obstructions. Acta Ophthalmol 2020; 98:396-399. [PMID: 31580002 DOI: 10.1111/aos.14263] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 09/08/2019] [Indexed: 11/28/2022]
Abstract
PURPOSE 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. METHOD 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. RESULTS 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. CONCLUSION 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.
