Study Summary

This trial will use a VR program to study how people with cortically-induced blindness drive in simulated environments. Computer vision, deep learning & gaze-contingent manipulations will be used to understand changes to their driving.

Who is the study for?

This trial is for US or Canadian residents aged 21-75 who've had a one-sided stroke affecting vision, confirmed by MRI/CT scans. Participants must have consistent visual field defects in both eyes and be able to understand instructions in English. They should consent themselves and can wear contacts if needed.Check my eligibility

What is being tested?

Researchers are using Virtual Reality (VR) to study how people with cortically-induced blindness from strokes adapt when driving. The VR program simulates real-world environments, tracking steering behavior to learn about changes in visual processing.See study design

What are the potential side effects?

Since this study involves a non-invasive VR task, traditional side effects associated with medical treatments are not expected. However, participants may experience discomfort related to VR use such as dizziness or nausea.

Experimental Treatment

Group I: Virtual Reality (VR) Driving Task: Healthy Control CohortExperimental Treatment1 Intervention

Healthy controls with no vision loss will perform a driving task in VR, in which they must steer through a series of parameterized turns while maintaining their virtual vehicle centered between the two red lines delineating the "road" edge.

Group II: Virtual Reality (VR) Driving Task: Cortically Blind CohortExperimental Treatment1 Intervention

Persons who have sustained cortical blindness will perform a driving task in VR, in which they must steer through a series of parameterized turns while maintaining their virtual vehicle centered between the two red lines delineating the "road" edge.
