Can a PowerPoint slideshow help stroke survivors see again?
NCT ID NCT06241209
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a simple PowerPoint program that shows moving images in the blind part of a person's vision can help expand their visual field. The trial enrolls 40 adults with hemianopsia (partial blindness) after stroke or brain injury. Participants will watch slides with objects like food or money, and researchers will measure if their vision improves using a standard eye test.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PowerPoint visual stimulation program
- What this could lead to
- If it works, this could offer a simple, low-cost way to partially restore vision in people with hemianopsia.
- What could go wrong
- This is a very small, early-stage study with only 40 participants. The visual stimulation is basic (PowerPoint slides) and may not produce meaningful or lasting improvement. There is a small risk of triggering seizures in susceptible individuals.
