Mobility improvement of patients with peripheral visual field losses using novel see-through digital spectacles.

ABSTRACT:

Purpose

To evaluate see-through Augmented Reality Digital spectacles (AR DSpecs) for improving the mobility of patients with peripheral visual field (VF) losses when tested on a walking track.

Design

Prospective Case Series.

Participants

21 patients with peripheral VF defects in both eyes, with the physical ability to walk without assistance.

Methods

We developed the AR DSpecs as a wearable VF aid with an augmented reality platform. Image remapping algorithms produced personalized visual augmentation in real time based on the measured binocular VF with the AR DSpecs calibration mode. We tested the device on a walking track to determine if patients could more accurately identify peripheral objects.

Main outcome measures

We analyzed walking track scores (n
