Long-term Follow-up Results of Primary Canaliculitis Patients.

Objectives: To evaluate the demographic characteristics, clinical presentation, microbiologic profile, and treatment results of patients with primary canaliculitis. Materials and Methods: Patients diagnosed and treated for primary canaliculitis between May 2014 and May 2021 were analyzed retrospectively. Results: There were 26 patients with primary canaliculitis, including 17 females (65.4%) and 9 males (34.6%) with a mean age of 50.6±16.4 years (range: 9-80 years). Canaliculitis affected the right eye in 11 patients, the left eye in 13 patients, and bilateral involvement was seen in 2 patients. Inferior canaliculus involvement was more frequent (73%). The most common complaint was epiphora (46.1%). Five patients (19.2%) were wrongly diagnosed as chronic conjunctivitis. The time interval between the beginning of symptoms and canaliculitis diagnosis was 18.2±14.3 months (range: 1-60 months). Canaliculotomy and curettage of canalicular content with dacryolith removal were performed in 23 patients. After surgery, antibiotic irrigation of the canaliculus was added to the treatment regimen in 12 of these 23 patients. Intracanalicular antibiotic therapy was administered to the remaining 3 patients. The most cultured organism was Actinomyces (6 patients). Gemella (1 patient), Porphyromonas (1 patient), Candida parapsilosis (1 patient), Citrobacter koseri (1 patient) were also grown in culture. The follow-up time of patients was 26.2±23.7 months (range: 6-83 months). All symptoms and findings resolved in all patients in one month. In two patients, recurrence occurred at 4 and 16 months after surgical treatment. With appropriate treatment, no further recurrence was seen in either patient over 24-month follow-up. One patient presented with iatrogenic canaliculus blockage during follow-up. Conclusion: Primary canaliculitis is often overlooked and can be misdiagnosed. The most common symptom was epiphora. All patients with epiphora and chronic conjunctivitis should be examined carefully for canaliculitis.

Efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis.

The objective of this study was to evaluate the efficacy and safety of super pulse CO2 laser-assisted punctoplasty with canalicular curettage in primary canaliculitis. In this retrospective serial case study, the clinical data of 26 patients who underwent super pulse CO2 laser-assisted punctoplasty for the treatment of canaliculitis were collected from January 2020 to May 2022. The clinical presentation, intraoperative and microbiologic findings, surgical pain severity, postoperative outcome, and complications were studied. Of the 26 patients, most were females (female:male 20:6), with a mean age of 60.1 ± 16.1 years (range, 19-93). Mucopurulent discharge (96.2%), eyelid redness and swelling (53.8%), and epiphora (38.5%) were the most common presentations. During the surgery, concretions were present in 73.1% (19/26) of the patients. The surgical pain severity scores ranged from 1 to 5, according to the visual analog scale, with a mean score of 3.2 ± 0.8. This procedure resulted in complete resolution in 22 (84.6%) patients and significant improvement in 2 (7.7%) patients, and 2 (7.7%) patients required additional lacrimal surgery with a mean follow-up time of 10.9 ± 3.7 months. The surgical procedure of super pulse CO2 laser-assisted punctoplasty followed by curettage appears to be a safe, effective, minimally invasive, and well-tolerated treatment for primary canaliculitis.

Chronic canaliculitis with canaliculoliths due to Providencia stuartii infection.

Canaliculitis, inflammation of the lacrimal canaliculi, can be caused by numerous pathogens, most commonly bacteria from the genera Actinomyces, Streptococcus, and Staphylococcus. Primary canaliculitis often requires surgical canaliculolith removal and appropriate antibiotic coverage. The authors report a case of a 77-year-old woman with a history of punctal plugs who presented with chronic canaliculitis with canaliculoliths that grew Providencia stuartii. P. stuartii has not previously been described as a cause of primary canaliculitis. This case highlights a new organism that causes canaliculitis with canaliculoliths and stresses the importance of speciation and antibiotic sensitivity testing following canaliculotomy and curettage. P. stuartii should be considered in the differential for bacterial canaliculitis with canaliculoliths, especially in patients with persistent symptoms on topical antibiotic therapy without canaliculotomy.

Microbiological profile of canaliculitis and their antibiotic susceptibility patterns: A 11-year review at a referral eye care centre.

PURPOSE: To analyze the microbiological profile and in vitro antibiotic susceptibility patterns of bacterial isolates in canaliculitis, an infection of the lacrimal drainage system of the eye. METHODS: The laboratory records of patients presenting with canaliculitis from whom specimens were obtained for microbiological investigations at our tertiary eye care centre in South India from January 2010 to December 2020, were reviewed. RESULTS: A total of 130 canalicular pus samples were collected from 112 patients and submitted for microbiological studies during the study period. A total of 183 micro-organisms were isolated from 115 culture-positive specimens. The micro-organisms isolated were predominantly aerobic Gram-positive bacteria (83.44%), with Coagulase-negative Staphylococci (CoNS/Other Staphylococcus spp) (31.69%), Corynebacterium spp (15.3%), Staphylococcus aureus (9.84%) and Viridans Streptococci (9.84%) accounting for a majority of the isolates. Actinomycesspp (6.56%) was the most common anaerobic bacterium isolated. Our study revealed several bacteria not previously associated with canaliculitis namely Ottowia spp, Elizabethkingiameningoseptica, Aeromonassalmonicida, Capnocytophagaochracea and Campylobacter gracilis. Polymicrobial aetiology was observed in 39.13% of culture-positive samples. Analysis of antibiotic susceptibility patterns of the isolates revealed a high proportion of Gram-positive bacteria susceptible to chloramphenicol (90.16%) compared to fluoroquinolones including ciprofloxacin (74.42%), norfloxacin (64.15%) and gatifloxacin (60.49%). CONCLUSION: This study represents the largest series of canaliculitis reporting the microbiological profile and antibiotic susceptibilities of the isolated micro-organisms, till date. Gram-positive bacteria accounted for a majority of isolates, predominated by Staphylococcus spp. The increasing resistance of Gram-positive bacteria to fluoroquinolones warrants antibiotic treatment in canaliculitis is based on in vitro antimicrobial susceptibility patterns.

Intracanalicular antibiotic ointment loading as a management option for canaliculitis.

AIM: The aim of the study is to describe intracanalicular antibiotic ointment loading as a treatment option for canaliculitis. MATERIAL AND METHODS: It was an interventional prospective study. The study was conducted over a 3 year period from June 2015 to June 2018. All patients of canaliculitis managed with intracanalicular antibiotic ointment loading and with a minimum follow up of 3 months were included in the study. The antibiotic ointment was loaded into the canaliculus based on the antibiotic sensitivity of the material expressed out from the canaliculus. Patients' demographics, clinical details, microbiological profile and management outcomes were evaluated. RESULTS: A total of 24 patients were included in the study. Mean age at presentation was 58.41 ± 9.4 years. The right eye was involved in 15 (62.5%, p = .0424) cases. The incidence of lower canaliculus involvement (14, 58.33%, p = .022) was significantly higher as compared to the upper canaliculus (8, 33.33%). Staphylococcus epidermidis and Actinomyces israelii (6, 25%) were the most commonly isolated organisms. Mean number of intracanalicular antibiotic loading sessions required was 4.21 ± 1.69 (range 2-8). Complete resolution of canaliculitis was seen in all (100%) cases. CONCLUSION: Canalicular antibiotic ointment loading is a minimally invasive, safe, and effective procedure. It preserves the anatomy and function of the punctum and canaliculus and can be considered as one of the management options for canaliculitis.

Multi-viral canaliculitis: case report and review of literature.

AIM: To report an atypical case of multiple viruses causing canaliculitis. METHODS: Case report of a young female presenting with atypical course of refractory unilateral canaliculitis with complete mid-bicanalicular obstructions. Canalicular scrapings were subjected to immunofluorescence techniques and polymerase chain reactions to identify the viruses. RESULTS: Investigations revealed a canaliculitis of multi-viral etiology; herpes simplex virus and varicella zoster virus. A canalicular curettage followed by topical acyclovir helped in the resolution of canaliculitis. CONCLUSION: An encounter with an atypical canaliculitis with negative bacteriology work up, suboptimal response to routine therapies, and mid-canalicular obstructions should alert the physician to investigate for viral etiology.

A case report on complete cure of recurrent primary canaliculitis by 4-snip punctoplasty and canalicular curettage.

RATIONALE: For the treatment of primary canaliculitis, 1,2,3-snip punctoplasty and canalicular curettage are commonly used; however, a recurrence rate of 6.6% to 22% has been reported. Herein, we describe a case of recurrent primary canaliculitis that was completely cured by 4-snip punctoplasty and canalicular curettage. PATIENT CONCERNS: A 53-year-old woman was admitted to our hospital with chief complaints of epiphora, discharge, eyelid flare up, and swelling near the inferior lacrimal punctum in the left eye, which initially presented 6 months earlier. DIAGNOSIS: Based on the aforementioned symptoms, the patient was initially diagnosed with bacterial conjunctivitis at a local ophthalmologic clinic and used antibiotic eye drops for 6 months. However, her symptoms did not improve and they worsened at 2 weeks prior to admission. She was subsequently diagnosed with chronic dacryocystitis and referred to our hospital for surgical treatment. Slit lamp examination results showed conjunctival congestion in the inner corner of the left eye, along with eyelid flare up, swelling near the inferior lacrimal punctum, and yellowish discharge and concretion from the lacrimal punctal orifice. Furthermore, punctal regurgitation was not observed in the lacrimal sac compression test. Thus, the patient was diagnosed with primary canaliculitis on the basis of her clinical symptoms and laboratory findings. INTERVENTIONS: Based on the diagnosis of primary canaliculitis, 1-snip punctoplasty and canalicular curettage were performed, and the patient was prescribed oral antibiotics for 2 weeks together with topical antibiotics for 4 weeks. Overall, the patient's symptoms improved after surgery, but epiphora and yellowish discharge from the lacrimal punctal orifice developed again 2 months after surgery during outpatient follow-up. Based on the diagnosis of recurrent primary canaliculitis, 4-snip punctoplasty and canalicular curettage were performed, and the patient was prescribed oral antibiotics for 2 weeks together with topical antibiotics for 4 weeks. OUTCOMES: Over a 6-month follow-up period, the symptoms disappeared completely and no other findings were observed. LESSONS: Four-snip punctoplasty and canalicular curettage are simple clinical procedures that can minimize the recurrence rate of primary canaliculitis. Hence, 4-snip punctoplasty and canalicular curettage should be considered as the 1st-line treatment for primary canaliculitis and recurrent cases.

Analysis of SmartPlug Insertion-Related Complications.

PURPOSE: To evaluate the complications and the treatment results of SmartPlug-related complications. METHODS: Retrospective review of all patients from a single medical hospital who received SmartPlug (Medennium, Inc., Irvine, CA) insertions from October 2007 to February 2014. All patients who developed SmartPlug-related canaliculitis and pyogenic granuloma were analyzed. Lacrimal irrigation with antibiotics was performed in most patients. RESULTS: Six hundred thirty-one eyes received SmartPlug insertion and 18 eyes developed SmartPlug-related complications (14 canaliculitis and 4 pyogenic granuloma). The mean time interval from insertion to development of the complications is 3.0 (0.5-6.9) years. Sixteen eyes received lacrimal irrigation with antibiotics, and all the eyes showed improvement without recurrence. The other two eyes had recurrence of granuloma pyogenica only after surgical excision. CONCLUSIONS: SmartPlug-related complications, including canaliculitis and granuloma pyogenica, required long-term follow-up. Most of the complications can be cured by lacrimal irrigation of antibiotics.

Actinomycetes canaliculitis complicating congenital nasolacrimal duct obstruction in an infant.

Actinomyces israelii is a Gram-positive anaerobic organism commonly associated with canaliculitis in adults. Pediatric canaliculitis is relatively rare, especially in infancy. We report the case of an 11-month-old boy who presented with co-existing canaliculitis and congenital nasolacrimal obstruction. The presenting signs included epiphora, discharge, conjunctival congestion, and matting of lashes. On examination, punctual pouting, regurgitation, and yellow canaliculiths were noted. A punctoplasty and canalicular curettage were performed along with nasolacrimal probing. Microbiological tests confirmed the organisms to be A. israelii. We discuss the clinical features and management of Actinomyces-associated canaliculitis and review the available literature on pediatric canaliculitis.

[Etiological and drug sensitivity analysis of lacrimal canaliculitis].

Objective: To analyze the etiology and drug sensitivity of lacrimal canaliculitis. Methods: Retrospective study of case series. The general information, culture results and drug sensitivity results of 52 patients (including 10 males and 42 females with an average age of 60.3 years) clinically diagnosed with lacrimal canaliculitis during 2011 and 2016 at Beijing Tongren Hospital of Capital Medical University have been analyzed. The enumeration data have been tested with Chi-square method. Results: The positive rate of bacterial culture was 78.8%, and the fungal culture tests of all cases showed negative results. Sixty strains of bacteria were isolated from 41 patients whose bacterial culture tests showed positive results, Gram-positive bacteria have been confirmed as the main among the isolated bacteria with Streptococcus (18.3%), Propionibacterium (18.3%), and Streptococcus (15.0%) identified as the three common genera. Thirteen cases (25.0%, all the 13 patients were female) involved with mixed infection, 13.3% (8/60) of the isolated strains were multi-drug resistant bacteria. The drug sensitive rate of the bacteria to fluoroquinolones antibiotics(79.3%, 230/290) was higher than that to cephalosporins(62.1%, 36/58) and aminoglycoside antibiotics(56.3%, 98/174), and such differences are of statistical significance (χ(2)=7.977, 27.738, P<0.05). Except for the fact that gram-positive bacteria are mostly sensitive to vancomycin, the sensitive rate of the bacteria to gatifloxacin was the highest and that to tobramycin was the lowest. Conclusion: Lacrimal canaliculitis tend to affect women and elderly patients. Staphylococcus, Propionibacterium, and Streptococcus are the three most common genera. Gatifloxacin may be the preferred antibiotic. Antibiotics combination therapy should be applied for multi-drug resistant bacteria. (Chin J Ophthalmol, 2018, 54: 111-114).

Canaliculitis due to Gemella haemolysans in a single isolate. / Canaliculitis por Gemella haemolysans en aislamiento único.

CASE REPORT: An 84 year-old woman was referred for evaluation of a painless swelling with small purulent discharge in her left upper canaliculus, and an associated epiphora of one-month duration. The patient was diagnosed with acute primary canaliculitis. She was treated with topical and oral antibiotics, as well as topical corticoids for three months, with little response. Surgical treatment with left upper canaliculotomy and curettage was then performed, and Gemella haemolysans was identified from the curetted material. The patient had no recurrence of the disease two months after the surgery. DISCUSSION: This is the first time that Gemella haemolysans is described as unique agent causing primary canaliculitis.

Novel Therapy for Primary Canaliculitis: A Pilot Study of Intracanalicular Ophthalmic Corticosteroid/Antibiotic Combination Ointment Infiltration.

In patients with primary canaliculitis, conservative medical therapy is associated with a high recurrence rate. Surgical treatments carry a great resolution rate but sometimes can result in the lacrimal pump dysfunction and canalicular scarring. The aim of this study is to introduce a minimally invasive approach, intracanalicular ophthalmic corticosteroid/antibiotic combination ointment infiltration (IOI, intracanalicular ointment infiltration), and to report our preliminary results for treating primary canaliculitis. In this retrospective, interventional case series, 68 consecutive patients with newly developed primary canaliculitis at a major tertiary eye center between January 2012 and January 2015. Thirty-six patients received conservative medical treatment alone (group 1; 36 eyes). Twenty-two patients and 10 medically uncontrolled patients from group 1 underwent IOI therapy (group 2; 32 eyes). Ten patients and 26 recurrent patients from group 1 and group 2 underwent surgery (group 3; 36 eyes). Patients were followed-up for at least 8 weeks. Clinical characteristics and outcomes were analyzed and compared. In this study, patients' age, sex, onset location, and durations of disease among 3 groups showed no significant difference. The resolution rate in group 2 was 72.7% (16/22) for new patients and 68.8% (22/32) for gross patients, respectively, both of which are higher than that of group 1 (22.2%, 10/36) but lower than that of group 3 (100%, 36/36). Of group 3, 2 patients received 2 surgical interventions and resolved finally. Microbiological workup was available in 51 patients. The most common isolates were staphylococcus species (27.9%) and streptococcus species (20%). Canalicular laceration developed in 1 patient during the IOI procedure and 1 patient undergoing surgery. Only 2 had postoperative lacrimal pump dysfunction and 1 had canalicular scarring in group 3. The IOI may be an effective and minimally invasive technique for treating primary canaliculitis and obviate the need for further intensive surgery.
