Restoration vs. Compensation in Neurovisual Rehabilitation of Visual Field Defects
Phase 2
Completed
- Conditions
- HemianopiaBrain Injuries, Traumatic
- Registration Number
- NCT04043429
- Lead Sponsor
- University of Magdeburg
- Brief Summary
Visual field defects (VFD) are a frequent effect of cerebral lesions especially after posterior cerebral artery stroke. The present study was conducted to compare effects of vision restoration training (VRT) and compensation training (Visual Exploration Training, VET) on visual field performance.
