Duct Obstruction

Abstract Background: Congenital nasolacrimal duct obstruction (CNLDO) is one of the main causes of epiphora in infants, and antibiotics are usually used as a conservative therapy in the first year. Yet, little is known about the bacteriology of the occluded lacrimal drainage system in this group of patients. The aim of this study was to evaluate the microbiology of lacrimal sac (LS) in Chinese children with CNLDO in their first year of life.Methods: Patients with CNLDO between May 1, 2017 and August 31, 2018 at a tertiary care children’s hospital were enrolled. The study recruited infants who received lacrimal probing under 1 year old, and refluxed discharge from LS was collected. Samples were cultured and susceptibility test was performed for positive culture.Results: Thirty-two patients with CNLDO were included. The ratio of male to female was 23:9. The mean age was 6.7 ± 2.4 (1.7-12) months. Positive cultures was identified in 87.5% of the sample, and presented 38 strains of bacteria. Mixed infection was identified in 10 (31.3%) children. Gram-positive bacteria accounted for 60.5% of all the strains, with Streptococcus (50%) being the most frequent species, whereas Haemophilus (21.1%) and Neisseriae (13.2%) were most common isolates for Gram-negative organisms. Methicillin-resistant Staphylococcus aureus (MRSA) was detected in 2 infants whose symptoms resolved by a routine probing. No difference of bacteriology pattern was detected between patients under 6 months old and those beyond. The pathogens were highly sensitive to chloramphenicol (88%) and levofloxacin (84%), but resistant to erythromycin (40%) and sulfamethoxazole (32%).Conclusions: Infants with CNLDO under 1 year of age presented predominance of Streptococcus as Gram-positive organism, and Haemophilus as Gram-negative organism. Levofloxacin was an active topical antibiotic agent with few chance of resistance especially for Chinese children. These findings could help clinicians choose optimal medicine for CNLDO as the conservative treatments.

Objective: To describe the management, complications and prognosis of lacrimalprobing in patients with congenital nasolacrimal duct obstruction (CNLDO). Materials and Methods: Retrospective, observational and analytical study. We studied the prevalence, symptoms and signs, both before and after probing, in patients with CNLDO diagnosed between 2010 and 2017 at Instituto Fundación Conde deValenciana. Results: The prevalence at our hospital of congenital nasolacrimal duct obstruction in children less than 1 year of age was 16.1%. 71 eyes of 56 patients undergoing probing were analyzed. 61% of patients were male. The right eye was affected in 46.4%.The average age of diagnosis of CNLDO was 10.2±7.6 months. 84.5% consulted for excessive tearing and 73.2% because of eye discharge. On ophthalmological examination, 71.8% had increased tear meniscus and 45.1% had discharge from punctum when digital pressure was applied to the lacrimal sac. The average age at the time of probing was 14.1±8.4 months. Subsequent to the probing, only 21.1% reported presence of tearing and 5.6% reported ocular discharge, both with a statistically significant reduction (p<0.05 from pre-op). After probing, only 16.9% of eyes had increased tear meniscus and 11.3% presented discharge from punctum after pressure at the lacrimal sac. Both decreases were statistically significant (p<0.05). 2 eyes (2.82%)of 2 patients required a second probing to obtain full resolution. Conclusion: Probing was successful in 76.1% of eyes. Success was observed even inpatients over 2 years of age. There was a statistically significant decrease of both signs and symptoms of CNLDO with lacrimal probing.
