Magnetic pulses to the brain may restore vision in adult lazy eye
NCT ID NCT05393739
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study tests whether a non-invasive brain stimulation technique called theta burst transcranial magnetic stimulation (TBS) can improve vision in adults with amblyopia, or lazy eye. Amblyopia affects about 3% of adults and currently has no effective treatment after childhood. Researchers will compare three types of TBS (intermittent, continuous, and sham) in 30 adults aged 20–50, measuring changes in visual acuity shortly after treatment and two weeks later.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- theta burst transcranial magnetic stimulation (TBS) procedure
- What this could lead to
- If it works, this could point toward a non-invasive treatment to improve vision in adults with amblyopia, for whom no effective therapy currently exists.
- What could go wrong
- This is a small, early-stage study with only 30 participants, so results may not apply broadly. The effects may be temporary or no better than placebo.
