Post-cataract Surgery Endophthalmitis by Multidrug Resistant Pseudomonas aeruginosa : Case Report

Endophthalmitis is the most devastating complications of cataract surgery that can lead to visual loss, blindness and death in severe cases. Pseudomonas aeruginosa is a gram negative rod that known to cause keratitis and endophthalmitis. The emergence of multidrug resistant Pseudomonas aeruginosa strains is a serious problem. The treatment of endophthalmitis by multidrug resistant Pseudomonas aeruginosa strains is very difficult due to the limitation for the choice of effective antibiotic. A 63-year-old woman was admitted to the hospital with severe pain and blurred vision. She had (PE+PCIOL) surgery in her right eye three days ago. Endophthalmitis was diagnosed and the Pseudomonas aeruginosa was identified in culture. The study of antimicrobial resistance pattern showed the Pseudomonas aeruginosa strain was multidrug resistant. After vitrectomy the patient had vision loss and finally the severe vitreous reaction led to death. Pseudomonas aeruginosa endophthalmitis is a rapidly progressive infection and associated with sight loss. The treatment of multidrug resistant Pseudomonas aeruginosa endophthalmitis is difficult and rapid treatment with appropriate antibiotic according to determination of antimicrobial resistance pattern is essential.
