A Comparative Study: Bacterial Spectrum and Antibiotic Resistance Patterns of External and Intraocular Ocular Infections

Terada Yutaka

Ocular infections are a common problem that can affect various parts of the eye, including the external structures and the intraocular compartments. Bacterial infections are a significant cause of ocular morbidity and can lead to vision loss if not properly treated. Understanding the bacterial spectrum and antibiotic resistance patterns in ocular infections is crucial for effective management and prevention of complications. In this article, we will explore the differences between external and intraocular diseases in terms of bacterial spectrum and antibiotic resistance patterns.

The bacteria from the external ocular surface were more sensitive to neomycin, while those from the intraocular specimens were more sensitive to levofloxacin. Multidrug resistance was found in 89 bacteria, including isolates from both external and intraocular samples. The results of this study indicate that the bacteria spectrum of external and intraocular infections is variable in the setting. A high percentage of bacterial organisms were found to be primarily susceptible to neomycin for external infection and levofloxacin for intraocular infection.
