Quick tool to identify what germ is causing a corneal ulcer

Automated Quantitative Ulcer Analysis (AQUA): Diagnosing Organism Types

NIH-funded research University of Michigan at Ann Arbor · NIH-11197618

This project is building an easy-to-use tool that looks at corneal ulcers to quickly tell doctors whether bacteria, fungi, or other organisms are causing the infection for people with painful corneal infections.

What this research studies

If I have a painful corneal ulcer, the team will develop an algorithm called AQUA that analyzes images and clinical data to classify the type of organism causing the infection. They will train and test AQUA using real patient photos and clinical records, then build a simple point-of-care decision tool clinicians can use when I come in. The researchers will check that the algorithm meets performance standards and refine how results are shown to eye doctors. The long-term aim is a low-cost, widely available tool that helps clinicians pick the right treatment faster and reduce vision loss.

Who could benefit from this research

Good fit: People with suspected microbial keratitis (painful corneal ulcers) who can have clinical photos and data collected at participating eye clinics.

Not a fit: People with non-infectious corneal problems, infections from very rare organisms not represented in the data, or those who cannot access participating clinics may not benefit.

Why it matters

Potential benefit: Could help doctors choose the right treatment faster and reduce vision loss from microbial keratitis.

How similar studies have performed: Image-based algorithms in ophthalmology are a relatively new approach but preliminary data for AQUA and other early studies suggest promise while broader validation is still needed.
