All samples were processed for direct microscopy, culture and identification by standard methods. Susceptibility testing was done by Kirby-Bauer method as per CLSI guideline.</p> <p><strong>Results</strong>: Out of 116 patients with ocular infections 130 samples were collected, from which 38 different organisms were isolated. Gram-positive cocci 21 (55%), gram-negative cocco-bacilli 5(31%) and gram-negative bacilli 12 (32%) were isolated. <em>Coagulase negative Staphylococci</em> (37%) and <em>Pseudomonas </em>species (21%) were the most commonly-isolated. Gatifloxacin has highest efficacy (89%) against all isolates. Majority of gram positive cocci were susceptible to vancomycin, gatifloxacin, cefazolin, gram negative cocco-bacilli to amikacin, tobramycin, fluoroquinolone and gram negative bacilli to gatifloxacin.</p> <p><strong>Conclusion</strong>: Majority of ocular infection is caused by gram positive organisms which were susceptible to vancomycin followed by gram negative organisms susceptible to amikacin, fluoroquinolone, gram negative cocco-bacilli to amikacin and tobramycin, and gatifloxacin effective against both type of organisms. The information provided in this article help the clinician in formulating rationale-based empirical antibiotic treatment of bacterial ocular infections.</p> <p><strong> </strong></p>}, number={01}, journal={National Journal of Medical Research}, author={Summaiya A, Mulla and Neeta D, Khokhar and Sangita B, Revdiwala}, year={2012}, month={Mar.}, pages={22–24} }
