Abstract

Connatal lacrimal duct stenosis (cLDO) commonly causes purulent bacterial dacyrocystitis. The recommended treatment of choice is up to the sixth month of life a conservative antimicrobiological therapy. After the sixth month lacrimal duct irrigation with silicone tube intubation remains the gold standard. Our purpose was to analyse the current bacterial spectrum in cLDO and to compile a bacterial resistogram in order to specify antimicrobiological therapy. 66 samples from the lacrimal duct of 6- to 16-month-old children (41 female, 25 male) were obtained by collecting the refluxing liquids with cotton wool swabs after irrigation of the lacrimal drainage system with sterile saline during lacrimal duct surgery. Cultures were incubated aerobically and anaerobically and the infectious agents were isolated. Sensitivity testing was performed for each isolate, testing 8 different commonly used local antibiotics. Data were statistically analysed using SPSS. Cultures were positive in cLDO in 97 %, showing co-colonisation in 87 % with up to five bacterial strains. Gram-positive bacteria were seen in 72 % of the isolates in cLDO with Streptococcus pneumoniae (31 %) being the most abundant strain, followed by Staphylococcus aureus (13 %) a...Continue Reading
