MICROBIOLOGIC SPECTRUM OF ACUTE AND CHRONIC DACRYOCYSTITIS

Abstract

Introduction: The aim of this study is to report the microbiological spectrum of dacryocystitis and the antibiotic sensitivity patterns of the organisms. It was a prospective study done at Department of Ophthalmology, Dr. D. Y. Patil Medical College and Hospital, Pimpri, Pune in 2015 on 42 cases of dacryocystitis.

Methodology: Patients were diagnosed with dacryocystitis and on the presence of a pus-filled lacrimal sac and peri lacrimal tissues for acute dacryocystitis. Chronic dacryocystitis patients were diagnosed by ROPLAS Test and sac syringing and were reviewed for demographic and microbiological profile.The culture results, organisms isolated, and their antibiotic sensitivity were studied.

Results: In this study 42 clinical samples were evaluated, among them 33(78.5%) were culture positive and rest were reported as no growth 9(21.5%). Among all positive growth, Staphylococcus aureus encountered as the commonest isolate (56%) followed by Streptococcus pneumoniae (2%) among the Gram-positive organisms .In the Gram-negative organisms, Escherichia coli (23%) followed by Pseudomonas aeruginosa (17%) was seen. Gram-positive organisms were commonly sensitive to flouroquinolones, penicillins and vancomycin whereas gram-negative organisms were sensitive to aminoglycosides.

Conclusion: Gram-positive and Gram-negative organisms were predominant in this study. The result has significant bearing on the treatment of patients and also when mass cataract surgeries are being performed.
