Drivers with hemianopia fail to detect pedestrians
Date:3/14/2014

BOSTON (March 14, 2014) A diagnosis of hemianopia, or blindness in one half of the visual field in both eyes as the result of strokes, tumors or trauma often means the end of driving.

In about half of the states in the United States and in many other countries, driving with hemianopia is prohibited. However, in some countries including Belgium, the Netherlands, the UK, Switzerland and Canada, driving with hemianopia is permitted after passing a specialized road test. Researchers at Massachusetts Eye and Ear/Schepens Eye Research Institute set out to determine the extent to which people with hemianopia can compensate for the lost vision when driving, with a long term goal of developing and evaluating devices and training that will assist them to drive more safely.

People with hemianopia have to look (scan) with eye and/or head movements toward the side of the field loss in order to see obstacles or hazards on that side. "The wide field of view that needs to be scanned at intersections presents an especially challenging situation for drivers with hemianopia as they have to scan larger angles than drivers with a full field of vision in order to see all of the intersection on the side of the field loss," said lead author Alex Bowers, Ph.D.

Bowers and colleagues used a driving simulator to evaluate head scanning behaviors of 14 drivers with hemianopia and 12 drivers with normal vision as they approached intersections. Their results are described in the March 12 issue of Investigative Ophthalmology & Visual Science in the paper: Driving with Hemianopia: IV. Head Scanning and Detection at Intersections in a Simulator.

"We found that participants with hemianopia showed compensatory scanning patterns in that their first scan was usually to the side of their field loss. Drivers with right hemianopia tended to look to the right before looking to the left. By comparison, the normally sighted drivers and drivers with left hemi
