New eye scan could replace dye injections for diabetic retinopathy
NCT ID NCT02330042
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study is testing whether a special type of eye scan called functional OCT can detect early blood vessel damage in people with diabetic retinopathy. Currently, doctors use a dye injection to see these changes, which can cause side effects. The study will enroll 165 people with diabetes to see if the scan can spot reduced blood flow, abnormal blood vessels, and swelling in the retina without needing a dye.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to a safer, dye-free way to monitor diabetic retinopathy and catch vision-threatening changes earlier.
What could go wrong
This is an observational study, not a treatment trial. The new scan may not prove reliable enough to replace current methods, and results may not apply to all patients.
