Driving Difficulties and Coping Strategies in Persons with Homonymous Quadrantanopia or Homonymous Scotoma

Area of Science:

• Neuroscience
• Ophthalmology
• Rehabilitation Science

Background:

• Homonymous visual field loss, often resulting from stroke, significantly impacts driving ability.
• Understanding the challenges and adaptive strategies of these drivers is crucial for road safety and independence.

Purpose of the Study:

• To investigate the driving challenges experienced by individuals with homonymous visual field loss.
• To identify the coping strategies employed by these drivers, including the use of Advanced Driver Assistance Systems (ADAS).

Main Methods:

• Conducted in-depth, semi-structured telephone interviews with four drivers diagnosed with homonymous quadrantanopia or homonymous scotoma post-stroke.
• Utilized open-ended questions to explore driving difficulties, coping mechanisms, and ADAS utilization.

Main Results:

• Primary difficulties involved perceiving objects on the side of visual field loss, especially at intersections and during lane changes.
• Common strategies included enhanced scanning, mirror utilization, increased following distance, avoidance of complex situations, and the use of ADAS (e.g., blind spot warnings, rearview cameras).
• Some drivers reported fewer difficulties over time as they adapted to their visual field loss.

Conclusions:

• Drivers with homonymous visual field loss develop compensatory strategies, including ADAS, to navigate driving challenges.
• Educating drivers about potential issues and adaptive techniques is vital for successful return to driving post-stroke.
