Home-based Vision Rehabilitation Guided by Brain Imaging (BRIGHT)

June 3, 2026 updated by: Tong (Tina) Liu, Georgetown University

Behavioral Rehabilitation Through Image-Guided Home-based Training

The BRIGHT (Behavioral Rehabilitation Through Image-Guided Home-based Training) study aims to evaluate the effectiveness of image-guided, home-based perceptual training at improving visual performance in individuals with visual field loss.

Using a prospective, crossover design, BRIGHT combines visual behavioral testing, neuroimaging, and a home-based intervention. It aims to 1) identify neural pathways that support training-induced visual plasticity; and 2) compare the efficacy of different types of visual training delivered in a home-based setting.

Description

Inclusion Criteria:

  1. At least 18 years of age.
  2. Capable of providing informed consent and complying with study procedures.
  3. Unilateral or bilateral focal brain damage causing visual field loss.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Perceptual learning-based training using high-level visual stimuli

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in high-level perceptual discrimination performance
Time Frame: Week 2-4 or Week 7-9 of the study (depending on the order)
Change in performance on an online computerized high-level perceptual discrimination task. Participants complete a computerized high-level perceptual discrimination task during a 3-week training period (5 days per week). Task difficulty is adaptively adjusted using a 3-up/1-down staircase procedure to estimate perceptual discrimination thresholds corresponding to approximately 75% accuracy.
Week 2-4 or Week 7-9 of the study (depending on the order)
Change in low-level perceptual discrimination performance
Time Frame: Week 2-4 or Week 7-9 of the study (depending on the order)
Change in performance on an online computerized low-level perceptual discrimination task. Participants complete a computerized high-level perceptual discrimination task during a 3-week training period (5 days per week). Task difficulty is adaptively adjusted using a 3-up/1-down staircase procedure to estimate perceptual discrimination thresholds corresponding to approximately 75% accuracy.
Week 2-4 or Week 7-9 of the study (depending on the order)
