Uveitis Without the Dye Test? An AI Model Scored Retinal Inflammation From Routine Eye Scans

Uveitis is inflammation inside the eye. When it affects the retina’s blood vessels, doctors usually track it with fluorescein angiography, a test that involves injecting a yellow dye into an arm vein and taking a series of photos. It works, but it takes time, the dye can cause nausea or rare allergic reactions, and it is hard to repeat as often as uveitis may need. At the Retina Society meeting in 2026, a research team showed that artificial intelligence may be able to read inflammation from routine scans instead.

What the study tested

Parisa Emami-Naeini, MD, MPH, presented a machine-learning model that combines two noninvasive images already taken in many clinics: optical coherence tomography (OCT), a cross-section scan of the retina, and ultra-widefield photos that show the outer retina.

What the results showed

• The OCT-based model correctly identified inflammation with 85% sensitivity and 97% specificity and matched expert dye-test grading closely.
• The widefield photo model also performed well and helped capture inflammation in the periphery.
• On an outside dataset from the University of Nebraska, both models still performed well.
• Combining the two produced a score that reflected overall disease better than either one alone.

Important cautions

Dr. Emami-Naeini said the model is not ready to replace the dye test. It still needs to be tested over time in new patients to confirm that the score goes up and down with real changes in inflammation and can guide treatment decisions. If that holds, it could allow more frequent, more objective monitoring between dye tests, and give researchers a common yardstick for trials.

What this means for you

• See an eye doctor promptly for a red, painful, light-sensitive eye or new floaters with blurred vision. Uveitis needs timely treatment.
• If you have an autoimmune condition, such as arthritis or inflammatory bowel disease, ask whether you need regular eye checks.
• Keep follow-ups even when the eye feels better; inflammation can be active without symptoms.

Our office refers uveitis care to uveitis and retina specialists. I am encouraged by any research that could make monitoring easier on patients.
