Background: Bacteria are major causative agents that frequently cause infections in the eyes and loss of vision. Resistance of bacteria isolated from the ocular to antimicrobial agents is a global concern.

Objective: The aim of this study was to determine the prevalence of bacterial isolates and their antimicrobial susceptibility pattern patients with external ocular infections with associated risk factors.

Methods: A cross sectional study was conducted from May 11, 2015 to August 24, 2015. A total of 288 samples were collected, the samples thus collected were and processed for bacterial culture according the standard procedures. Presumptive isolates were further identified by a series of biochemical tests. The antimicrobial susceptibility patterns of the isolates were determined by disk diffusion method. The data were entered and analyzed using SPSS software version 20.


Conclusion: The prevalence of bacterial pathogens among external ocular samples was high. Most of the isolates were drug resistance for commonly used antibiotics. Gentamicin and Ciprofloxacin was the most effective antimicrobial agents for both gram-positive and gram-negative bacteria.

Keywords: external ocular infections, antimicrobial agents, susceptibility pattern.
