Could a daily electric zap to the eye preserve sight in dry AMD?
NCT ID NCT07700147
First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This trial investigates whether a personal-use electric stimulator, worn at home for 30 minutes daily, can improve vision in people with early to intermediate dry age-related macular degeneration (AMD). Participants are randomly assigned to receive either real or sham stimulation for 12 weeks. The study measures changes in visual acuity and contrast sensitivity, and tracks any side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcutaneous electrical stimulation device (LRTPM1)
- What this could lead to
- If effective, this device could offer a non-invasive, at-home treatment to slow vision loss and improve visual function in people with dry AMD.
- What could go wrong
- This is a small, early exploratory trial with only 40 participants. The sham-controlled design helps, but results may not generalize, and the device may not provide meaningful benefit.
