Abstract:

Abstract Purpose To investigate the microstructure of the lacrimal canaliculus and the characteristics of lacrimal canalicular diseases by 80-MHz ultrasound biomicroscopy (UBM). Methods This study included 33 participants: 20 normal subjects (40 eyes), 2 patients with chronic lacrimal canaliculitis (4 eyes), 10 patients with chronic dacryocystitis (16 eyes), and 1 patient with lacrimal punctum atresia (2 eyes). All participants underwent 80-MHz UBM; disease-specific features were noted. Results On 80-MHz UBM of the lacrimal canaliculi (vertical section) in normal subjects, low echo of the lacrimal canalicular lumen and high echo of the lacrimal canalicular wall were observed. The uniform low echo near the wall was the mucosal epithelium. The outermost layer of medium-to-high echo was the subepithelial elastic fibrous layer. In the horizontal section, the lumen was continuous. Two linear high echoes parallel to the canalicular wall could be observed at the center of the lacrimal canaliculus, which were sometimes attached and sometimes separated. When separated, the center of the lacrimal canaliculus was a low echo area (lumen). Lacrimal canaliculitis (vertical section) showed obvious ectasia of the lacrimal canalicular lumen, with a high echo mass shadow, which might have been calculi, and uneven thickness of the mucosal epithelium with a slightly high echo shadow. In the horizontal section, the lumen varied in size with clear boundaries of medium and high echoes. The central linear high echoes of the lumen were absent, and the echoes of the mucosal epithelium were discontinuous. In chronic dacryocystitis, the lacrimal canalicular lumen was extensively enlarged, with continuous echoes and uniform thickness of the mucosal epithelium and homogeneous patches of slightly higher echoes. Lacrimal punctum atresia indicated that the lacrimal canaliculus existed in both eyes and its structure was normal. Conclusions The 80-MHz UBM is a new non-invasive technique that can be used for clear visualization of the fine structure of the lacrimal canaliculus, including the mucosal epithelium and subepithelial elastic fiber layer. The use of this approach will improve understanding of the hierarchical structure of the lacrimal canaliculi and provide a comprehensive basis for diagnosis, differential diagnosis, and treatment plan in patients with lacrimal passage diseases.

Abstract:

Purpose.The study aimed to investigate canalicular/lacrimal sac mucosal folds (CLS-MFs) in vivo and in cadavers in order to explore their functional roles in the lacrimal drainage system.Method.The observations of CLS-MFs in vivo were performed on 16 patients with chronic dacryocystitis after undergoing an endonasal endoscopic dacryocystorhinostomy (EE-DCR). The lacrimal sacs and common canaliculi of 19 adult cadavers were dissected. The opening/closing of an orifice and mucosal fold was recorded. All of the specimens were subjected to a histological examination.Results.The upper and lower lacrimal canaliculi in all of the samples united to form a common canaliculus that opened to the lacrimal sac. CLS-MFs were observed in 10 of the 16 patients (62.5%) and 9 of the 19 cadavers (47.4%). The orifices or mucosal folds could be opened or closed when related muscles contracted or relaxed. Histological sections showed a mucosal fold at one side of an orifice.Conclusion.Common canaliculus is the most common type that the canaliculus opens to lacrimal sac. CLS-MFs exist in a certain ratio that can be opened/closed with the movement of the orifices. They may be involved in the drainage of tears or the pathogenesis of acute dacryocystitis or lacrimal sac mucocele.

Abstract:

Purpose. The aim of this study is to propose a simple and efficient combination surgery for the management of dacryocystitis with canalicular obstruction.Methods. A retrospective noncomparative case series of dacryocystitis with canalicular obstruction has been studied. Twelve patients with dacryocystitis and canalicular obstruction underwent a conventional endoscopic endonasal dacryocystorhinostomy (EE-DCR) combined with a modified canalicular repair. Postoperative observations included slit lamp, fluorescein dye disappearance test, lacrimal syringing, lacrimal endoscopy, and nasal endoscopy.Results. After 6–18 months of postoperative follow-up, the symptoms of epiphora and mucopurulent discharge disappeared completely in 10 patients, and occasional or intermittent epiphora remained in 2 patients. All of the twelve patients showed an opened intranasal ostium and normal fluorescein dye disappearance test. Patent bicanalicular irrigation was achieved in 9 patients. One patient had a partial and the other two had a complete reobstruction by lacrimal irrigation to their repaired lower canaliculus; however, all of them had a patent lacrimal irrigation to upper canaliculus. The functional success rate for the combination surgery is 83% (10/12), and anatomical success rate is 75% (9/12).Conclusion. EE-DCR combined with modified canalicular repair is a simple and efficient method for the management of dacryocystitis with canalicular obstruction.

Abstract:

Background.Lacrimal infections byActinomycesare rare and commonly misdiagnosed for long periods of time. They account for 2% of all lacrimal diseases.Case Report.We report a case of a 70-year-old female patient suffering from a para-canalicular abscess in the medial canthus of the left eye, beside the lower punctum lacrimale, resembling a chalazion. Purulence exited from the punctum lacrimale due to inflammation of the inferior canaliculus (canaliculitis). When pressure was applied to the mass, a second exit of purulence was also observed under the palpebral conjunctiva below the lacrimal caruncle. A surgical excision was performed followed by administration of local antibiotic therapy. The histopathological examination of the extracted mass revealed the existence of actinomycosis.Conclusion.Persistent or recurrent infections and lumps of the eyelids should be thoroughly investigated.Actinomycesas a causative agent should be considered. Differential diagnosis is broad and should include canaliculitis, chalazion, and multiple types of neoplasias. For this reason, in nonconclusive cases, a histopathological examination should be performed.

Abstract:

Purpose Accurate identification of the factors contributing to epiphora is essential in directing appropriate management and treatment strategies. The authors applied a methodical strategy of assessment for epiphora to patients who were already on the waiting list for dacryocystorhinostomy (DCR). The findings were compared to the original findings. Methods Forty-four eyes of 35 patients listed for DCR were re-examined. All canaliculi were examined using four tests: dye disappearance, Jones 1 (dye retrieval), probing using Bowman probes, and syringing of the nasolacrimal duct (NLD) under local anesthesia. Some patients were examined using an endocanalicular mini-endoscope. Patients with NLD obstruction underwent DCR and those with canalicular and NLD stenosis underwent intubation of the lacrimal system-canaliculus, lacrimal sac, and nasolacrimal duct-using silicone stents. The authors refer to this as canaliculodacryocystoplasty (CDCP). The patients were assessed for symptoms of epiphora at 12 months. Forty-four eyes had been listed for DCR. They had been originally diagnosed, by means of lacrimal syringing, as NLD obstruction (24 eyes) or stenosis (12 eyes), and functional blocks (8 eyes). Results Four out of the original 44 planned DCR surgeries were performed after re-evaluation. After re-examination, 28 lacrimal systems were found to have canalicular stenosis, 4 NLD stenosis, 4 NLD obstruction, 4 punctal phimosis, 3 ocular surface disease, and 1 patient was asymptomatic. Twenty-eight lacrimal systems underwent CDCP, 4 underwent DCR, 4 had punctoplasty, and 4 had probing alone. Three had treatment for ocular surface disease and one patient required no treatment. After a follow-up of 12 months, 41 (93%) systems had improvement or were free of their epiphora. Conclusions Syringing of the lacrimal apparatus may result in a high false positive diagnosis of NLD obstruction. Canalicular pathology is not uncommon in this cohort of patients and may be underdiagnosed.

Abstract:

Eyelid injuries commonly occur as a result of blunt or sharp periocular trauma. When the medial canthal region is affected, injury can be associated with canalicular laceration or avulsion. Complete loss of the lacrimal canaliculus associated with epiphora is a challenging condition, and reconstruction often leads to poor and disappointing results. Surgical treatment of a patient following blunt facial trauma that resulted in medial avulsion of the lower eyelid with tissue loss is presented. A 72-year-old male patient presented with avulsion of the medial 2/3 of the left lower eyelid together with complete loss of the inferior canaliculus. Eyelid tissue was not preserved. The inferior canaliculus was reconstructed using a Mini Monoka (FCI Ophthalmics), which was sutured under the caruncle and was enveloped with surrounding tissue. Loss of the lower eyelid tissue was substituted with a medially shifted Hughes flap and free skin transplant from the ipsilateral upper eyelid. The Hughes flap was divided after 2 weeks, while the Mini Monoka extruded spontaneously approximately 3 months after the injury. Ten months after the injury, the opening of the reconstructed lower canaliculus was positioned under the caruncle and was patent on probing and syringing. The patient is without epiphora and is satisfied with the functional and aesthetic result. In eyelid injuries we follow certain rules of reconstruction, but each case is unique and requires some inventiveness. The idea of inferior canalicular reconstruction following lower-eyelid avulsion with tissue loss is presented.

Abstract:

Purpose Few studies have focused on the intranasal localization of the lacrimal sac during endoscopic dacryocystorhinostomy: landmarks in order to find the medial wall of the lacrimal sac have been described, but there is a lack of description of methods for the verification of the complete marsupialization of the lacrimal sac during surgery. In this report, we propose an easy and effective method for certain intraoperative identification of lacrimal sac. Methods A method in order to verify the effective marsupialization of the lacrimal sac is applied and described: to ensure that the opening of the sac in the nasal cavity is complete, the surgeon should identify the Rosenmuller valve, which is the end of the common canaliculus in the lacrimal sac. Continuous irrigation with saline solution through the inferior canaliculus can be useful to obtain a clean surgical area and to permit easy intraoperative identification of the valve. Results Between 2007 and 2015, 193 endoscopic dacryocystorhinostomies were performed in our institutions. Postoperative surgical success at last follow-up (minimum 12 months) was 93.8% (181 out of 193 of cases). No major complications were observed. Conclusions Correct and complete exposure of the lacrimal sac during surgery is crucial for a good outcome: when the opening of the common canaliculus is identified, the surgeon is assured that the sac has been correctly and completely marsupialized inside the nasal cavity.

Abstract:

AIM: To identify the risk factors of epiphora in patients with anatomical patency after surgical repair of canalicular laceration. METHODS: This retrospective case series included 178 cases of canalicular laceration repair from 2005 to 2012. Demographic data collected from each patient included age, sex, type of injury, distance from the distal lacerated end of the canaliculus to the punctum, the severity score for the structural abnormity of the medial canthus, the duration of stent placement, and the timing of surgery. The risk factors for epiphora were evaluated using Logistic regression models. RESULTS: Among the 178 cases, 45 (25.3%) with lacrimal patency after irrigation had symptomatic epiphora at the final follow-up. Patients’ sex, age, type of injury, duration of stent placement, timing of surgery, and concurrent trauma were not found to be signi?cantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus (P>0.05). A distance of more than 5 mm from the distal cut end to the punctum was closely and significantly associated with symptomatic epiphora after surgical repair of the lacerated canaliculus (P<0.01). Symptomatic epiphora was significantly more frequent in patients with higher severity scores for structural abnormities of the medial canthus (P<0.01). CONCLUSION: Our results indicate that the risk factors for postoperative symptomatic epiphora include a further distance between the distal cut end and the lacrimal punctum and a higher severity score for structural abnormities of the medial canthus. These findings could be used to prognosticate postoperative symptomatic epiphora.

Abstract:

42 children at age from 1 to 15 years (36 - with relapse of congenital nasolacrimal duct (NLD ) stenosis and 6 - with canalicular stenosis) bougienage NLD was done with Ritleng stent intubation. The control group included 25 children 1-5 years old with relapsed congenital stenosis of the NLD, the treatment of which was limited to probing the NLD. In the first group full functional effect was observed in 21 children (58.3 %), in 9 (25.0 %) - was light epiphoria, in 1 (2.8 %) - moderate, and in 5 (13.9 % ) treatment was not effective. In the second group a full functional effect was obtained for each child. In the control group lacrimal drainage was restored fully in 16 (64.0 %) children, in 2 (8.0 %) - moderate and in 7 (28.0 %) - severe epiphora was remained. Using of silicone intubation with the Ritleng lacrimal system allows to continuously retain their foramen in stenotic site without causing an inflammatory response and bedsores lacrimal punctum and canaliculus.

Abstract:

Purpose: To introduce the novel effective Y-shaped silicon stent for treating canalicular laceration. Methods: Fifty-four canalicular laceration cases (54 eyes) underwent the lacrimal surgery using the novel Y-shaped silicon stents were collected, and the stents were removed 3 months after surgery. All cases were followed up for 12 months. The operability of stenting and removing the stent were assessed. The data we collected during each follow-up are: stent position and integrity, aesthetic results, the discomfort, the symptom of epiphora, the patency of lacrimal passage, complications, and patient’s satisfaction. Results: The stenting time was 14.3±5.8 min and the time of removing it was 1.8±0.5 min. Both of the operability of stenting and removing were accessed to be easy in more than 94.4% cases. All stents were in position and integrated. 51 cases (94.4%) had no problems on aesthetic results. Three patients (5.4%) complained about the discomfort. Two cases (3.7%) had the symptom of epiphora, which were obstructed after removing the stents. Fifty-two cases (96.3%) were with patent canaliculus and satisfied with the surgery and symptom improvement. Only 5 cases (9.3%) had complications. Conclusion: The novel Y-shaped silicon stent is an effective stent for treating canalicular laceration.

Abstract:

A 79-year-old female with a history of keratoconjunctivitis sicca presented with several years of epiphora of both eyes. Thirteen years earlier, intracanalicular Herrick lacrimal plugs (Lacrimedics, Eastsound, WA, USA) had been placed in both eyes to treat her dry eye syndrome. After 13 years the patient felt the epiphora was intolerable and underwent endoscopic dacryocystorhinostomy (DCR) of the left, then the right side. Intraoperatively, during the right endoscopic DCR, a Herrick lacrimal plug was found in the common canaliculus into the lacrimal sac. Postoperatively, the patient did well with improved epiphora. The Herrick plug is designed to be intracanalicular, and this case illustrates that the plug can migrate and be retained for many years. Collared punctal plugs have a lower risk of this type of complication.

Punctal plugs are popular device used for treatment of dry eyes. The SmartPlug, with its special thermodynamic properties, has the advantage to conform to the shape of the punctal ampulla and proximal canaliculus, and offers effective occlusion. However, SmartPlug related complications are not uncommon and surgical interventions are often required for management of persistent infection. This is a report of two middle-aged Asian women who developed chronic lacrimal canaliculitis after insertion of the SmartPlug Punctal Plug. Attempts at removing the SmartPlug failed and prolonged topical antibiotics resulted only in partial resolution of the infection. Subsequent forced irrigation with penicillin solution via the affected puncta using large bore lacrimal canula successfully led to complete resolution of the canalculitis.

Abstract:

The causes of nasolacrimal duct stenosis in adults can vary greatly. In general, the symptoms can also vary, but most cases share a tendency toward recurring inflammations in the prestenotic area. The treatment of these disorders is limited to either conservative therapy to control inflammation or surgically invasive measures. By using balloon catheters, usually applied in percutaneous transluminal coronary angioplasty (PTCA), dilation of the relative postsaccal stenosis can be performed under radiographic control. An exact diagnosis using various testing methods, including digital dacryocystography for detailed localization and documentation of any pathologic changes, is decisive to success. Only in cases of incomplete postsaccal stenosis is retrograde balloon dilation of the distal nasolacrimal duct indicated. A guide wire, designed for the PTCA balloon catheter set, is introduced via the canaliculus to the nasal cavity antegradely and caught with a thin hook and pulled from the naris, under visual control with an image converter. The balloon catheter is retrogradely threaded over the guide wire. The balloon is then placed at the site of the pathologic stenosis under radiographic control and dilated with high pressure. To ensure the permeability of the system, monocanalicular silicone intubation has to be performed immediately afterwards. This procedure has been performed successfully on 6 patients with a follow-up of 6 to 27 months. These initial results give rise to the hope that this minimally invasive, interdisciplinary technique represents a new alternative in the treatment of incomplete postsaccal lacrimal stenosis.

Abstract:

<p class="abstract"><strong>Background:</strong> The most critical element for successful management of lacrimal system pathology distal to common canaliculus that requires endoscopic endonasal dacrocystorhinostomy (EEDCR) is the creation of widest possible marsupialisation of the medial wall of the lacrimal sac. With minor modifications and simplication of the original technique of EEDCR, common surgical failures like obstruction of neo-ostium by granulation tissue or infolding of flap can be avoided. To determine the success of EEDCR using inferiorly based mucosal flap, removal of overlying bone using Kerrison’s punch followed by vertical incision of the medial wall of lacrimal sac with microdebrider assisted trimming of the lacrimal sac flaps.</p><p class="abstract"><strong>Methods:</strong> A total of 31 patients with epiphora secondary to nasolacrimal duct obstruction (NLDO) were operated using the above technique with 3 bilateral cases amounting to a total of 34 procedures. The surgical outcome and long term patency of neo-ostium were evaluated. </p><p class="abstract"><strong>Results:</strong> Of the 34 procedures, 32 procedures (94.1%) had complete resolution of epiphora at the end of one year follow up. The 2 failures were due to canaliculitis.</p><p class="abstract"><strong>Conclusions:</strong> Powered EEDCR with trimming of medial wall of lacrimal sac and inferiorly based mucosal flap preservation to cover the exposed part of bone is a simple procedure with favourable long term outcome.</p>

Abstract:

Purpose. To study features of the lower punctum in normal subjects using spectral domain anterior segment optical coherence tomography (SD AS-OCT).Methods. Observational cross-sectional study that included 147 punctae (76 subjects). Punctae were evaluated clinically for appearance, position, and size. AS-OCT was used to evaluate the punctal shape, contents, and junction with the vertical canaliculus. Inner and outer diameters as well as depth were measured.Results. 24 males and 52 females (mean age44±14.35 y) were included. Lower punctum was perceived by OCT to be an area with an outer diameter (mean412.16±163 μm), inner diameter (mean233.67±138.73 μm), and depth (mean251.7±126.58 μm). The OCT measured outer punctum diameter was significantly less than that measured clinically (P: 0.000). Seven major shapes were identified. The junction with the vertical canaliculus was detectable in 44%. Fluid was detected in 34%, one of which had an air bubble; however, 63% of punctae showed no contents and 4% had debris.Conclusions. AS-OCT can be a useful tool in understanding the anatomy of the punctum and distal lacrimal system as well as tear drainage physiology. Measuring the punctum size may play a role in plugs fitting.

Abstract:

Dacryocystorhinostomy (DCR) is a bypass surgery in which an anastomosis is made between the medial wall of the lacrimal sac & the lateral wall of the nasal mucosa by cutting the intervening bone at the level of middle meatus to restore the flow of tears when the obstruction is beyond the common canaliculus. The only successful treatment of chronic dacryocystitis is DCR. The aim of this study was to evaluate the surgical intervention of conventional external DCR without silicon tube intubation. This prospective study was conducted at General Hospital, Faridpur from July 2012 to June 2014. Eighty cases with chronic dacryocystitis were selected for the study. We excluded the patients with lacrimal fistula, failed DCR and gross nasal pathology like deviated nasal septum, grossly hypertrophied inferior turbinate, atrophic rhinitis, nasal tumour, and polyp from our study. The patients' mean age at the time of surgery was 41.9±8.1 years ranged from 30 to 60 years. The operation was done under local anaesthesia by applying same technique. Then the patients were followed up for 12 months. In this study, we observed recurrence in five patients (6.25%) and complications from DCR are infrequent and not sight threatening. There were seven patients with reactionary haemorrhage, one wound infection, three wound gap, two epicanthal fold, one granuloma formation and five failed DCR. The success rate is 93.75% who underwent external DCR for the management of epiphora due to nasolacrimal duct obstruction.Faridpur Med. Coll. J. Jan 2015;10(1): 20-22

Abstract:

Purpose. Evaluation of using pigtail probe to detect and open severely stenosed lower lacrimal punctum followed by self-retaining bicanalicular intubation. Study design. A prospective nonrandomized clinical study. Methods. The study included 24 patients with severe lower punctal stenosis (grade 0 according to Kashkouli scale) attending at Menoufia University Hospitals. The upper punctum and canaliculus were patent. All patients were complaining of epiphora and had a thorough ophthalmological examination including dye disappearance test and slit-lamp examination. Pigtail probe was used from patent upper punctum to detect the lower stenosed punctum which was opened with a scalpel. Syringing of the lower lacrimal passages was done to confirm its patency, and self-retaining silicone bicanalicular stent was inserted. The silicone tube was left in place for 6 months before it was removed. Patients were then followed-up for 1 year after the surgery. Results. One year after surgery, epiphora was absent (grade 0) in 16 eyes (66.7%) and was present only occasionally (grade 1) in 4 eyes (16.7%). The difference from preoperative epiphora was statistically significant. One year after surgery, fluorescein dye disappearance time was grade 1 (<3 minutes) in 20 cases (83.3%), and grade 2 (3–5 minutes) in 4 cases (16.7%). There was a statistically significant difference compared with preoperative results. Conclusion. Using the pigtail probe is effective in treatment of severe punctal stenosis. Maintaining the punctal opening and prevention of restenosis can be achieved by using self-retaining bicanalicular stent after confirmation of nasolacrimal duct patency. This trial is registered with NCT03731143.

Abstract:

Lacrimal canaliculitis is a rare infection of the lacrimal canaliculi with canalicular concretions formed by aggregation of organisms. Metagenomic shotgun sequencing analysis using next-generation sequencing has been used to detect pathogens directly from clinical samples. Using this technology, we report cases of successful pathogen detection of canalicular concretions in lacrimal canaliculitis cases. We investigated patients with primary lacrimal canaliculitis examined in the eye clinics of four hospitals from February 2015 to July 2017. Eighteen canalicular concretion specimens collected from 18 eyes of 17 patients were analyzed by shotgun metagenomics sequencing using the MiSeq platform (Illumina). Taxonomic classification was performed using the GenBank NT database. The canalicular concretion diversity was characterized using the Shannon diversity index. This study included 18 eyes (17 patients, 77.1 ± 6.1 years): 82.4% were women with lacrimal canaliculitis; canalicular concretions were obtained from 12 eyes using lacrimal endoscopy and six eyes using canaliculotomy with curettage. Sequencing analysis detected bacteria in all samples (Shannon diversity index, 0.05–1.47). The following genera of anaerobic bacteria (>1% abundance) were identified: Actinomyces spp. in 15 eyes, Propionibacterium spp., Parvimonas spp. in 11 eyes, Prevotella spp. in 9 eyes, Fusobacterium spp. in 6 eyes, Selenomonas spp. in 5 eyes, Aggregatibacter spp. in 3 eyes, facultative and aerobic bacteria such as Streptococcus spp. in 13 eyes, Campylobacter spp. in 6 eyes, and Haemophilus spp. in 3 eyes. The most common combinations were Actinomyces spp. and Streptococcus spp. and Parvinomonas spp. and Streptococcus spp., found in 10 cases. Pathogens were identified successfully using metagenomic shotgun sequencing analysis in patients with canalicular concretions. Canalicular concretions are polymicrobial with anaerobic and facultative, aerobic bacteria.
