Abstract: 

Purpose: To identify the bacterial and fungal pathogens causing ocular infections in patients attending a tertiary care hospital. Materials and Methods: All patients diagnosed with ocular infections presented between August 2013 to July 2014 were evaluated. The patients were examined under slit lamp biomicroscope and specimen was obtained using standard protocols. Results: Out of 222 patients, 96 had conjunctivitis, 30 patients had keratitis, 53 patients as Dacryocystitis, 37 had eyelid infections and 6 patients had intraocular infections. Among 96 conjunctivitis, 41(42.7%) showed bacterial growth. Staphylococcus aureus (67.7%) was most commonly isolated among gram positive organisms and Escherichia coli (70%) among gram negative organisms. Among 30 keratitis patients, 8 showed fungal growth. Fusarium spp. was most commonly isolated. In Dacryocystitis patients, incidence was 28(52.8%). The commonest isolate was Staphylococcus aureus (59.1%) followed by Escherichia coli (66.7%). Among eyelid infections, incidence was (56.8%). Coagulase Negative Staphylococcus 12 (57.1%) was commonly isolated followed by Staphylococcus aureus 9 (42.9%). Conclusion: In our study, Bacterial pathogens were more commonly isolated than fungal pathogens. The predominant bacteria isolated being Staphylococcus aureus. In keratitis, Fungal pathogens were more commonly isolated predominant being Fusarium spp.It is therefore important in culturing the samples in patients with these infections to prevent the emergence of resistant strains.
