Aim:to identify the organisms associated in cases of chronic dacryocystitis caused by rhinosporidiosis of lacrimal sac

Design: Prospective study.

Methods: A prospective analysis of 32  lacrimal sac contents of patients with chronic dacryocystitis, with confirmed diagnosis of lacrimal sac rhinosporidiosis by histopathology after dacryocystectomy conducted during the period from April 2017 to March 2018. Material was obtained directly from the lacrimal sac while making performing external dacryocystectomy for chronic dacryocystitis with clinical suspicion of rhinosporidiosis. Samples were also collected from ipsilateral conjunctiva and inferior meatus of nose. The specimens were smeared and cultured in the dept of microbiology and results analyzed

Results: All the patients were in age group of 25–50. Gram positive bacteria i.e., Coagulase negative staphylococci and Staphylococcus aureus were the most common isolates (83.33% and 16.67% respectively).

Conclusion: Majority of the chronic dacryocystitis cases caused by lacrimal sac rhinosporidiosis were associated with Coagulase negative Staphylococci and Staphylococcus aureus.
