Purpose: : To determine the diagnostic accuracy of manual regurgitation on pressure over the lacrimal sac (ROPLAS) versus lacrimal irrigation for screening nasolacrimal duct obstruction (NLDO) in adults prior to intraocular surgeries.Methods: This cross-sectional study took place in a tertiary eye care hospital in South Tamil Nadu, India. From January to December 2017 and included consecutive patients who presented for routine cataract surgery. Prospective data collection occurred in 8369 eyes of patients who underwent cataract surgery. All patients underwent ROPLAS testing by an ophthalmologist followed by lacrimal irrigation by trained ophthalmic assistants, rechecked or confirmed in equivocal cases by ophthalmologists who were masked to the ROPLAS status. The primary outcome, the sensitivity, specificity, positive, and negative predictive values to detect lacrimal occlusion by ROPLAS compared with lacrimal irrigation with 95% confidence intervals was estimated.Results: : A total of 8369 eyes underwent cataract surgery during the time periods of the study. ROPLAS and lacrimal irrigation were performed in all eyes. The sensitivity of ROPLAS to diagnose NLDO correctly was 54.5% (95% CI, 44.8%-63.9%) and its specificity was 100% (95% CI, 100%-100%). The positive and negative predictive values were 75.3% (95% CI, 65.6%-83.0%) and 99.4% (95% CI, 99.2%-99.5%), respectively.Conclusion: : We found that ROPLAS when used alone had very low sensitivity and low positive predictive value in detecting NLDO prior to cataract surgery as compared with lacrimal irrigation. Hence, we recommend performing ROPLAS and lacrimal irrigation in every patient as part of the routine preoperative workup prior to cataract surgery. [ABSTRACT FROM AUTHOR]

This study was designed and intended to reveal the etiology of epiphora or Watery eyes referrals to ophthalmology department in Baquba teaching hospital. Cross-sectional study we blindly select 200 patients complaining of epiphora Baquba teaching hospital. Data collection was done in the ophthalmology department in outpatient clinic of the hospital. Patient demographics, past history and ophthalmic examination has been done for the selected subjects. There were 200 subjects with a primary complaint of epiphora. They included (55%) females and (45%) males with an average age of 56.9±23.9y. The most common causes of epiphora were lacrimal obstruction (50%); followed by reflex tearing (36%) and eyelid malposition (14%). Differences in prevalence of aetiology were noted in the terms of age and gender distribution. In conclusion, epiphora is a common condition generally affecting babies and older people with many etiology. A thorough history and examination are required to provide the appropriate treatment to the underlying cause. [ABSTRACT FROM AUTHOR]

PURPOSE: The purpose of this study is to assess the outcomes of lacrimal gland injections of botulinum toxin A (BoNTA) for epiphora secondary to lacrimal drainage disorders and functional epiphora. METHODS: This was a retrospective interventional case series where cases were divided into functional and nonfunctional epiphora. RESULTS: A total of 37 eyes of 31 patients were identified: 13 males and 18 females. The mean age was 52 years (median = 53, range 29–86). The functional epiphora group had seven patients (8 eyes), subcategorized into hypersecretion (5), crocodile tears (1), and post seventh nerve palsy (1). Obstructive group (nonfunctional) had 24 patients (29 eyes), subcategorized into proximal canalicular block (12), common canalicular block (6), punctal stenosis (3), posttraumatic nasolacrimal duct obstruction (1), and partial nasolacrimal duct obstruction (1). Median preinjection Munk scores were similar in both groups (Grade 4). At 1 month, the median Munk score improved to 1 and 2 in functional and nonfunctional groups, respectively, after receiving a median dose of 4 units of BoNTA. Median reduction in Munk score was 75% in functional group versus 50% in nonfunctional group (P = 0.07). No difference in terms of complications was noted (transient ptosis). CONCLUSIONS: Reduction in epiphora after lacrimal gland injection of botulinum toxin is seen in cases with functional epiphora as well as those with a physical obstruction in the lacrimal drainage pathway. While the symptomatic improvement was more in functional epiphora, the difference between the two groups was not statistically significant.

The purpose of this study was to determine and compare the effects between injecting botulinum toxin A (BTX-A) transconjunctivally into the palpebral lobe and transcutaneously into the orbital lobe of the lacrimal gland in patients with epiphora due to lacrimal outflow obstruction. This randomized controlled study included 53 eyes of 31 patients with unilateral or bilateral epiphora. Patients were randomly allocated to receive an injection of BTX-A (3 units) either transconjunctivally (n = 15, 25 eyes) or transcutaneously (n = 16, 28 eyes). For objective assessments, the tear meniscus height and Schirmer’s I test with topical anesthesia were measured at baseline and after 2, 6, 12, and 24 weeks of follow-up. Subjective evaluations were performed using the Munk score. After BTX-A injection, patients in both groups experienced significant objective and subjective reductions in tearing at all follow-up times compared to pre-injection (success rate 86.8%), and the effect lasted for a mean duration of 5.63 months. The two delivery routes showed similar clinical effectiveness for a single injected dose of BTX-A. In conclusion, injecting BTX-A via either a transconjunctival or transcutaneous route helps to reduce normal tear production and results in significant improvements in the symptoms in patients with epiphora.

While tearing patients have similar complaints, the etiology of their symptoms may vary widely and thus require a meticulous evaluation. A thorough history followed by systematic examination of the lids, ocular surface, anterior segment, and lacrimal system will lead the clinician to the proper diagnosis. Treatment options for lacrimal obstruction are varied and as surgical techniques continue to evolve, new studies are indicated to determine the approaches that provide the most successful outcomes while ensuring patient safety.

AIM:To investigate triple channel double ring guided treatment of lacrimal obstruction and its clinical therapeutic effect. METHODS: Fifty cases(54 eyes)of lacrimal obstruction were treated by laser or micro-drill under triple channel lacrimal endoscope with double ring guided intubation created by our department. The silicone tube was extracted at 3～6mo of postoperation. All cases were followed up 3～6mo. RESULTS:Of total 54 eyes, 47 eyes were cured, and lacrimal passage was clearly flushed without epiphora; 5 eyes were improved, but lacrimal passage was clearly flushed with slight epiphora; 2 eyes were recurred, and lacrimal passage was not clearly flushed with epiphora. Total effective rate was 96%. CONCLUSION:Triple channel double ring guided treatment of lacrimal obstruction has greatly improved traditional operation. It has dramatically increased success rate of lacrimal obstruction operation with little invasion, avoiding formation of false lacrimal passage, quick recovery and less complications.

Abstract: Objectives: The objectives of this study are to report the outcomes of pediatric patients with lacrimal system obstruction who underwent primary endoscopic dacryocystorhinostomy (EDCR). Study design: The authors conducted a retrospective noncomparative case series. Methods: The operative and postoperative data have been collected in 58 children aged between 3 months and 13 years (mean 4.1 years). The total of 58 primary EDCRs has been performed by two surgeons using a standardized surgical technique. The EDCRs were performed 52 times on one eye, 6 times on both eyes (3 times simultaneously, 3 times at the separate sitting with an interval of 4–6 months). The follow-up evaluations include taking history, clinical examinations including a fluorescein disappearance test. Results: The follow-up interval ranged from 12 to 36 months (mean 17 months, median 15 months). The success rate was 51/58 (87.9%) in all 58 EDCRs. The success rate was 47/51 (92.2%) in the group of postsaccal obstructions, 3/5 (60.0%) in the group of postsaccal and suprasaccal obstrutions and 1/2 (50.0%) in presaccal obstructions. The procedures were successful in all eight children aged under 1 year old (100%) and in 14 of 15 children between 1 and 2 years old (93.3%). The silicone intubation was used in 54 EDCRs. Conclusions: The endoscopic DCR is a safe and effective procedure for most children with the success rate comparable to that achieved in the external DCR and in adults. The success rate of the postsaccal obstructions is significantly higher than in presaccal or combined pre- and postsaccal obstructions. [Copyright &y& Elsevier]

Purpose: To compare the anatomical pattern of lacrimal drainage system obstruction (LDSO) associated with topical anti-glaucoma medications (AGM) with a control group. Methods: In a cross-sectional controlled study, case group included patients on topical anti-glaucoma medications and control group included patients with no history of glaucoma, free of ocular disease, and not using topical medications. Data recording, eye examination, and categorization of patients into case and control groups were performed by a senior ophthalmology resident. Diagnostic probing and irrigation test was performed by an oculoplastic surgeon who was masked to the patients’ data. Chi-square (X2) and tests were used to assess the effect of sex and systemic diseases, as well as logistic regression analysis with intra-cluster correlation for the effect of topical anti-glaucoma medications on lacrimal drainage system, and then independent sample t-tests to compare the mean ages, plus the binary logistic regression test for the effect of increasing age on LDSO. Results: There were 128 eyes of 96 patients in the case and 277 eyes of 172 patients in the control group. Two groups were similar regarding to the age, sex, and associated systemic disorders (0.3

Patients with conjunctival cicatrizing disease may develop lacrimal obstruction. Little is published on lacrimal obstruction as the presenting feature of otherwise asymptomatic cicatrizing conjunctival disease. The records of all patients presenting between 1994 and 2015 with lacrimal obstruction found to have cicatrizing conjunctival disease were reviewed. Demographic details, clinical findings, disease progression and treatment were analyzed. Thirty-five patients (25 female), aged 43–91 years (median 74, mean 71.3 years) had epiphora and a mild conjunctival cicatrizing process. Nine patients had onset of epiphora after cataract surgery. All except one patient had obstruction of the proximal lacrimal system (punctum and/or canaliculus). In 14 cases, the obstruction was unilateral (both puncta or canaliculi), with one progressing to bilateral obstruction after 11 years. In 19, all 4 puncta or canaliculi were obstructed. Two patients had unilateral nasolacrimal duct obstruction; one developed contralateral canalicular obstruction 2 years later. Conjunctival biopsies were obtained in 19 of 35 cases (54%), and OCP immunohistochemistry was positive in 7/19 (37%). All other biopsies showed chronic inflammation. Two patients had lichen planus. In follow-up (range 0.1–11 years, mean 3.2 years), 2 patients’ conjunctival disease progressed mildly, and 3 progressed moderately, with 2 of these 5 having positive OCP immunohistochemistry, and 1 having lichen planus. Patients with conjunctival cicatrization may present with lacrimal obstruction, usually punctal or canalicular. Conjunctival disease is usually mild and non-progressive, but patients should be monitored for disease progression. [ABSTRACT FROM PUBLISHER]

PurposeTo evaluate the long-term patency of lacrimal drainage system (LDS) after balloon dacryocystoplasty (BD) and to give the long-term success rates according to the severity and localization of the obstruction.MethodsBetween May 1993 and December 2003, BD was attempted in 117 eyes of 108 patients with idiopathic-acquired LDS obstruction. Patients with active dacryocystitis, dacryolithiasis, traumatic obstruction or lacrimal mass, obstructions at the superior or inferior canaliculi lateral to the common canaliculus, and follow-up period less than 36 months were excluded from the study.ResultsThe results of BD were evaluated in 99 eyes of 94 cases. The obstruction was seen at the common canaliculus in seven eyes, proximal nasolacrimal duct in 70 eyes, and distal nasolacrimal duct in 22 eyes. The mean follow-up period was 100.0±38.4 months (range: 36–142 months). The long-term overall success rate was 40.8% (20/49 eyes) in complete obstruction and 68% (34/50 eyes) in partial obstruction. The clinical success rate was 57.1% in common canalicular (complete: 33.3%, partial: 75%), 50% in proximal nasolacrimal duct (complete: 38.5%, partial: 64.5%), and 68.2% in distal nasolacrimal duct (complete: 57.1%, partial: 73.3%) obstructions. The overall success was 54.5% (54/99 eyes) for the entire series at the last clinical follow-up visit.ConclusionThe long-tem success rate of BD for the treatment of epiphora is low and is not comparable to conventional dacryocystorhinostomy. More predictable results can only be achieved in carefully selected patients and this procedure can be recommended in cases demonstrating partial obstruction of the distal nasolacrimal duct.Eye (2008) 22, 1483–1487; doi:10.1038/sj.eye.6702912; published online 24 August 2007 [ABSTRACT FROM AUTHOR]

BACKGROUND After the advent of dacryocystorhinostomy (DCR), dacryocystectomy (DCT) was regarded as mutilant surgery and reserved for lacrimal sac tumors. PURPOSE To present current indications for dacryocystectomy. METHODS Eighteen eyes from 11 patients subjected to DCT were reviewed retrospectively. Nine patients had chronic dacryocystitis confirmed by dacryocystography and two patients had lacrimal sac tumors. RESULTS The indications for DCT were: three patients with systemic medical problems, three patients with dry eye, two cases of lacrimal sac tumors, two cases of traumatic dacryocystitis and one case of cutaneous leishmaniasis. Dacryocystitis was resolved in 17 of 18 eyes; the two cases of tumor evolved without epiphora. One patient (traumatic dacryocystitis) had recurrence of dacryocystitis. CONCLUSIONS DCT is mainly performed when a lacrimal sac tumor is suspected but, since it avoids the intra- and postoperative complications related to dacryocystorhinostomy, it can be indicated in cases of dacryocystitis with significant lacrimal discharge and an enlarged or altered lacrimal sac.

Lacrimal pathway stenoses in pediatric patients are uncommon after the age of 1 year. Various conservative treatments (massages, hot compresses, topical antibiotics, probing and intubation of the lacrimal pathways) are generally used to resolve these disorders. When non-invasive procedures fail, dacryocystorhinostomy (DCR) is indicated. While this surgical procedure has traditionally been performed by an external approach, a less-invasive endonasal technique has recently been advocated. We herein review a series of six children affected by lacrimal pathway stenosis who were treated at the Department of Pediatric Otorhinolaryngology, Spedali Civili, Brescia (Italy) between November 2000 and January 2002. All patients underwent successful transnasal endoscopic DCR and, to date, no re-stenoses have occurred. A review of the literature focusing on diagnostic work-up and different therapeutic options is also presented. [Copyright &y& Elsevier]

Purpose: To describe the association between the use of various types of topical ocular medications and acquired lacrimal canalicular obstruction in 14 patients. Methods: The records of all patients in the author's practice with either lacrimal canalicular or punctal occlusion associated with the use of topical ocular medication were reviewed. Results: Fourteen cases were identified. The obstructions occurred at any point from the punctum to the common canaliculus, but most commonly occurred 2-5 mm from the lacrimal punctum. There was an association with various degrees of clinically apparent subconjunctival scaring maximal at the inner canthus, rarely to a severe degree, with symblepharon, medial canthal keratinization and cicatricial medial entropion. In some cases, no subconjunctival scarring could be clinically detected. Topical medications used were often multiple and included prednisolone acetate/phenylephrine hydrochloride ( n= 5), timolol maleate ( n= 5), pilocarpine ( n= 3), dipivefrine hydrochloride or adrenaline ( n= 3), chloramphenicol ( n= 3), tobramycin ( n= 3), indomethacin ( n= 2), ecothiopate iodide ( n= 1), betaxolol ( n= 1), dexamethasone ( n= 1), tropicamide ( n= 1) and the long-term use of naphazoline and various artificial tear preparations ( n= 1). The duration of exposure ranged from 3 weeks to 20 years, with seven patients having used drops for 3-6 weeks. Seven patients had surgical repair, three by dacryocystorhinostomy (DCR) and glass by-pass tube (all successful), three by canalicular repairs (one failed) and one by DCR and canalicular repair that restenosed at the puncta, who then had successful punctoplasty and silicone intubation. Conclusions: Lacrimal canalicular obstruction may occur after relatively short-term exposure to topical ocular medications or as part of a more widespread cicatricial reaction in patients on long-term medication. While a direct causal relationship cannot be confirmed, there appears to be a strong association and the site of the obstructions makes other causes unlikely. [ABSTRACT FROM AUTHOR]
