Background:
Infectious keratitis remains a significant cause of vision impairment worldwide, particularly in developing countries like Vietnam, where socio-economic factors and environmental conditions contribute to its prevalence.
Purposes:
This study aims to investigate the epidemiology, risk factors, and microbiological causes of infectious keratitis at Ho Chi Minh City Eye Hospital, Vietnam, from August 2019 to January 2020.
Methods:
A descriptive study of 56 cases was analyzed using microbiological tests, including smear microscopy, culture, and RT-PCR.
Results:
Bacterial and fungal pathogens were the most common causes of infection, each responsible for approximately 35.71% of cases, with 17.86% exhibiting polymicrobial infections. Risk factors for infectious keratitis included trauma, systemic conditions like diabetes, and ocular conditions such as previous herpetic keratitis. Furthermore, RT-PCR was found to be more sensitive than traditional culture methods in detecting bacterial pathogens.
Conclusion:
These findings underscore the importance of timely intervention and improved diagnostic methods to mitigate the burden of infectious keratitis in Vietnam.
