The results of a 10-year ongoing study led by Penny A. Asbell, MD, FACS, MBA, FARVO, chair of the Department of Ophthalmology and director of the Hamilton Eye Institute (HEI), have been published recently in the Journal of the American Medical Association (JAMA) Ophthalmology. This surveillance study examines isolates from eye infections across the United States and analyzes trends in antibiotic resistance.

The Antibiotic Resistance Monitoring in Ocular micRoorganisms (ARMOR) surveillance study evaluated in vitro antibiotic resistance rates in ocular bacteria collected from 41 states (88 medical centers) from 2009 to 2018. The study, titled Trends in Antibiotic Resistance Among Ocular Microorganisms in the United States From 2009 to 2018, found that antibiotic resistance was prevalent in ocular bacteria (staphylococci), and bacteria that were resistant were also likely to be multi-drug resistant. Antibiotic resistance was also found to be higher in the southern and western parts of the United States, as well as more common in older patients.

Dr. Asbell and her colleagues will continue the nationwide study, which is sponsored by Bausch + Lomb, a global eye health business. She hopes that the coming years of research will answer more of their questions, leading to even better methods for treating patients with serious eye infections and ultimately, preservation of vision.
