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.
