Purpose: The purpose of this study is to determine the microbiological spectrum and the demographics of dacryocystitis patients. Methods: A retrospective chart review on patients’ electronic medical records were utilized to collect data on patients who presented with dacryocystitis. A total of 97 patients were included and data were collected on the demographics, type of organisms, antibiotic sensitivity, response to antibiotics therapy, management, and complications. Results: Gram-positive cultures predominated in all genders in both adult and pediatric age groups and accounted for 61.3% of the sample. In adults, Staphylococcus aureus was the leading gram-positive organism (25.7%) while Pseudomonas aeruginosa(7.9%) and Haemophilus influenzae (6.9%) were the most common gram-negative organisms. In pediatric cases, Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, and Streptococcus intermedius were equally prevalent and gram-negative infection was exclusively due to Haemophilus species (26%). Conclusions: Comprehending the microbiologic spectrum and its trend is crucial for managing an infection and recommending suitable antibiotic therapy. Initial Empirical therapy for dacryocystitis cases is targeted toward the Gram-positive organisms due to its prevalence. As a result, we heartily advise conducting a local study from time to time to assess the trend in the microbiological spectrum and shift in epidemiology, along with the antimicrobial sensitivity.

Purpose To investigate the microbiology and antimicrobial susceptibility of dacryocystitis in adults and identify the changing trends over time in Taiwan. Methods This is a single-centered, retrospective study. We retrospectively reviewed adult patients with dacryocystitis from January 2012 to December 2021 in a tertiary medical center in Taiwan. The pathogens and in vitro antimicrobial susceptibility of the pus cultures from the lacrimal sac were collected. Results Thirty-five cultures in acute and 211 cultures in chronic dacryocystitis were collected. Of the 220 isolates, a similar proportion of gram-positive (44%) and gram-negative (43%) aerobes were demonstrated in chronic dacryocystitis and more gram-negative aerobes (50%) than gram-positive aereobes (41%) in acute dacryocystitis. The most common pathogens were methicillin-resistant Staphylococcus aureus (MRSA; 28.1%) and Pseudomonas aeruginosa (28.1%) in acute dacryocystitis, while coagulase-negative Staphylococci was the most common micro-organism in chronic dacryocystitis. The effective antibiotics for gram-positive aerobes were vancomycin (100%), moxifloxacin (88%) and trimethoprim/sulfamethoxazole (78%). Meropenem (95%), amikacin (93%), and levofloxacin (91%) were sensitive to more than 90% of gram-negative aerobes in current study. High resistant species were also isolated in our cohort. Conclusion More gram-negative pathogens and more resistant species are rising in adult dacryocystitis. Understanding the bacteriology and antimicrobial susceptibility of the region is crucial for the empirical antibiotic selection in clinical practice.
Dacrocystitis has a very high incidence in india. It can be treated by external by external/ endonasal approaches of dacrocystorhinostomy. In the recent times a lot of emphasis was given upon the endonasal approach. This study throws light upon those factors and determines which amongst the two methods of dacrocystorhinostomy is better.
