Timing eye injections: could 3, 7, or 14 days before surgery matter?
NCT ID NCT06300918
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial tests whether giving anti-VEGF injections 3, 7, or 14 days before surgery makes a difference for people with proliferative diabetic retinopathy, a complication of diabetes that causes abnormal blood vessels in the eye. Participants are randomly assigned to one of three timing groups. Using a new technique that allows fluorescein angiography during surgery, the study will compare how well each timing suppresses these abnormal vessels, aiming to identify the most effective approach.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- anti-VEGF drugs (injected into the eye before surgery)
- What this could lead to
- If successful, this could identify the optimal timing for anti-VEGF injections before surgery, potentially improving outcomes for people with proliferative diabetic retinopathy.
- What could go wrong
- This is a small, early-stage trial, and the results may not apply to all patients. The best timing could vary based on individual factors, and the study may not find a clear difference.
