Could a zappy headband save your sight? stanford tests new glaucoma device

NCT ID NCT06685211

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether a device called Eyetronic, which delivers mild electrical pulses through the eyes, can help people with glaucoma. Glaucoma damages the optic nerve and can lead to vision loss. The trial will compare the active device to a sham (fake) version in 30 adults with moderate glaucoma. Researchers will measure changes in vision and eye structure over three months to see if the stimulation helps protect sight.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Eyetronic rtACS device (non-invasive electrical stimulation)
What this could lead to
If it works, this could offer a new, non-invasive way to slow vision loss and preserve sight in people with glaucoma.
What could go wrong
This is a very small early-stage trial with only 30 people, so results may not apply to everyone. The treatment is also compared to a sham device, so any benefit might be small or due to a placebo effect.
