Summary

This study tests whether a non-invasive brain stimulation technique called tDCS can safely improve vision in 100 children aged 4-14 with lazy eye (amblyopia) that hasn't improved with standard patching. Children will receive either real or sham tDCS over three sessions, and their vision will be measured before, after, and up to three months later. The goal is to see if this device can boost visual recovery by enhancing brain plasticity.

What this could mean

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

Active substance: transcranial direct current stimulation (tDCS) device
What this could lead to: If it works, this could offer a non-invasive, child-friendly way to improve vision in children with lazy eye who haven't benefited from patching.
What could go wrong: This is an early-stage trial with only 100 participants and no phase designation. The treatment is short-term (3 sessions), so lasting benefits are uncertain. Mild side effects from brain stimulation are possible.
