Mixed Reality Glasses with Picture-in-Picture Navigation for Patients with Homonymous Hemianopic Visual Field Loss.

Background: The visual rehabilitation options for patients with homonymous hemianopia (HH) are limited. We developed prototype software for commercially available mixed reality glasses (MRG) to help patients with HH better navigate their visual environment.

Methods: Unlike virtual reality, mixed reality allows users to see the actual environment with superimposed holograms.
