Vision Improvement Through Behavioral Rehabilitation And Neuroplasticity Training
Visual Plasticity Following Brain Lesions
Source: ClinicalTrials.gov · Last updated 14 Sept 2026
Brief summary (registry, in English)
The VIBRANT (Vision Improvement through Behavioral Rehabilitation And Neuroplasticity Training) study is a prospective, double-blind, crossover design (within-subject) in participants with homonymous hemianopia-a type of visual field loss resulting from damage to the post-chiasmatic visual pathways. It aims to investigate whether transcranial random noise stimulation (tRNS) combined with perceptual learning-based training has potential for improving visual impairments.
