Vision Loss Impact on Navigation in Virtual Reality

Description

The purpose of this research is to better understand the impact of cortically-induced blindness (CB) and the compensatory strategies subjects with this condition may develop on naturalistic behaviors, specifically, driving. Using a novel Virtual Reality (VR) program, the researchers will gather data on steering behavior in a variety of simulated naturalistic environments. Through the combined use of computer vision, deep learning, and gaze-contingent manipulations of the visual field, this work will test the central hypothesis that changes to visually guided steering behaviors in CB are a consequence of changes to the visual sampling and processing of task-related motion information (i.e., optic flow).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Residents of the United States or Canada
  • * Presence of one-sided stroke or stroke-like damage to primary visual cortex or its immediate afferent white matter sustained within the specified age range of 21 - 75 years (verified by MRI and/or CT scans)
  • * Reliable visual field defects in both eyes (homonymous defects) as measured by Humphrey or equivalent perimetry.
  • * Willing, able, and competent to provide their own informed consent
  • * Cognitively able, responsible to understand written and oral instructions in English
  • * Emmetropic or else wear corrective contact lenses inside the virtual reality headset
  • * Those who have never driven or earned a drivers' license
  • * Past or present ocular disease interfering with visual acuity
  • * Best corrected visual acuity (BCVA) worse than 20/40 in either eye
  • * Sustained damage to the dorsal lateral geniculate nucleus
  • * Presence of diffuse, whole-brain degenerative processes
  • * Presence of brain damage deemed by study staff to potentially interfere with outcome measures
  • * History of traumatic brain injury
  • * Documented history of drug/alcohol abuse
  • * Diagnosis of cognitive or seizure disorders
  • * Diagnosis of one-sided attentional neglect
