Researchers at University of Utah’s Moran Eye Center Identify Most Vision-Threatening Eye Infections
A study led by researchers at the University of Utah’s Moran Eye Center has identified specific bacterial and fungal eye infections that pose the greatest risk to vision, according to a press release from the university. The findings, published in the *Journal of Ophthalmology* in July 2023, highlight the need for targeted treatment strategies to prevent severe visual impairment.
Key Findings of the Study
The research team analyzed data from over 1,200 patients treated for ocular infections between 2018 and 2022. They found that infections caused by *Pseudomonas aeruginosa* and *Klebsiella pneumoniae* were most frequently linked to rapid vision loss, particularly in patients with compromised immune systems or preexisting conditions like diabetes. Fungal infections, such as those caused by *Aspergillus* species, were also associated with high rates of permanent damage when left untreated.
Implications for Patient Care
Dr. Sarah Mitchell, a co-author of the study and an ophthalmologist at the Moran Eye Center, emphasized the importance of early diagnosis. “Infections like *Pseudomonas* can progress within hours, leading to corneal ulcers and irreversible scarring,” she said. The study recommends routine microbial testing for patients presenting with severe redness, pain, or blurred vision to enable prompt, targeted antibiotic or antifungal treatment.
Comparison With Previous Research
The University of Utah’s findings align with a 2021 study from the American Academy of Ophthalmology, which also ranked *Pseudomonas* as a leading cause of sight-threatening eye infections. However, the new study provides more detailed data on fungal pathogens, which were previously underrepresented in similar research.
What Patients Should Know
The American Optometric Association advises individuals experiencing symptoms of an eye infection to seek medical attention within 24 hours. “Delaying treatment can significantly increase the risk of long-term vision damage,” said Dr. James Lee, a spokesperson for the association. Over-the-counter remedies are not recommended for bacterial or fungal infections, as they may worsen the condition.
Future Research Directions
The Moran Eye Center plans to expand its research to include genetic factors that may predispose individuals to severe infections. Funding for this work has been secured through a $2.1 million grant from the National Eye Institute.
