  • Lesions implicating the cortical centre for sight in the occipital lobe give rise to hemianopia -- that is, loss of sight in the lateral halves of the fields of vision of both eyes -- colour-blindness, subjective sensations of light and colour, and other eye symptoms.

  • She and Peli believe the Schepens study, because it was conducted in the safety of a driving simulator over a longer period of time and "miles" than a typical "on-road" study, provides new insights into detection failures of drivers with hemianopia.

  • Peli and his research team compared 12 subjects with hemianopia to 12 visually normal people, matched by age, sex, and years of driving experience.

  • The next step for the team is to determine whether an optical aid that expands the visual field - peripheral prism (expansion prism EP) glasses - might be a useful device for drivers with hemianopia.
