Results of the Cultured Jones Tubes Used in Lacrimal Bypass Surgery

Purpose: We evaluated cultured specimens from removed Jones tubes and their antibiotic sensitivities. Methods: In 16 patients who had received lacrimal bypass surgery to resolve nasolacrimal duct obstruction, the Jones tubes were removed due to either recurred symptoms, signs of chronic dacryocystitis, the tubes being obstructed, or migration of the tubes. Jones tubes were cultured to identify bacteria and tested for their antibiotic sensitivity. Results: The average duration from intubation to removal was 11.5 months. Nine cases showed the tube obstruction and six cases showed recurrent inflammation as the respective causes of tube removal. The species of cultured bacteria were Staphylococcus aureus in 9 cases, Pseudomonas in 4 cases, Streptococcus in 2 cases and coagulase negative Staphylococcus in 2 cases. In 1 case, both Staphylococcus aureus and Pseudomonas were cultured. In antibiotics sensitivity tests, 8 of 9 cases of Staphylococcus aureus were resistant to penicillin. The symptoms and signs of nasolacrimal duct obstruction were improved after the tube removal. Conclusions: When treating an obstruction of the lacrimal apparatus due to chronic dacryocystitis using lacrimal bypass surgery with Jones tubes, Staphylococcus aureus and Pseudomonas aeruginosa should be suspected as the main cause of inflammation of the nasolacrimal system or nasal cavity.
