Abstract

Purpose: We investigated the regional characteristics and trends in causative agents, clinical features, and antibiotic susceptibility in infectious keratitis in western Gyeongnam province.
Methods: This retrospective chart review included 551 eyes of 551 patients with infectious keratitis, who were referred to our center from January 2004 to December 2017. The period of this study was divided into two terms of 7 years before and after 2011 to analyze the changes in causative organisms and antibiotic susceptibilities and to investigate the clinical features and regional characteristics in western Gyeongnam province.
Results: The most common occupation among patients was farming; the mean time taken for initial treatment was 8.6 days. The culture positivity rate was 35.8%, the most commonly isolated microorganisms were Staphylococcus epidermidis (14.5%) for Gram-positive bacteria and Pseudomona aeruginosa (13.5%) for Gram-negative bacteria. The distribution of culture-positive organisms before and after 2011 did not show any significant difference, but the increase in resistance to second and third generation quinolones was significantly greater in Gram-positive bacteria after 2011. There was no significant difference in clinical characteristics before and after 2011, but the hospital stay duration and treatment needs were significantly reduced.
Conclusions: This was a large-scale study analyzing the clinical features of infectious keratitis in western Gyeognam province over a 14-year period. The results will help us understand the characteristics, microbiology, and community in infectious keratitis by analyzing patients referred to tertiary centers.
