Summary

This small proof-of-concept study tested a non-invasive device that uses sound and light to help people with hemianopia (blindness in half of the visual field). Five adults with stable hemianopia underwent training sessions where they were exposed to matching sound and visual cues in their blind area. The goal was to see if this multisensory approach could improve visual detection. Results are very early and limited.
