Could insulin eye drops save your sight? new trial launches
NCT ID NCT07619482
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether insulin eye drops can protect the optic nerve in people with open-angle glaucoma. Researchers will give 90 participants either insulin drops or placebo daily for up to 12 months. The main goal is to check safety, but they will also measure vision changes and eye structure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- topical sterile human insulin eye drops (EYED-002)
- What this could lead to
- If successful, this could provide a new way to protect the optic nerve and slow vision loss in glaucoma patients.
- What could go wrong
- This is an early-phase trial focused on safety, so it may not show clear benefit. Insulin eye drops could cause eye irritation or affect blood sugar.
