[POSTER] Visual Field Expanding Peripheral Prisms Improve Detection of Roadside Pedestrians in Patients with Hemianopia

…For hemianopia, peripheral prisms (p-prisms) expand the visual field up to 40° on standard perimetry (Jung and Peli, 2014). In prior studies, p-prisms improved self-reported mobility scores over a sham in a randomized controlled clinical trial (Bowers, 2013) and improved responses to hazards in a pilot on-road study. However, gaze was not tracked in either of these studies and there was no control over when or where hazards appeared. We therefore conducted a study to objectively measure detection and gaze behavior with the p-prisms in the controlled environment of a driving simulator…
