A randomised trial of vision restoration therapy

Background and purpose: Evidence from pilot studies suggests a beneficial effect of Vision Restoration Therapy (VRT) in patients with retro-chiasmatic visual pathway lesions. We investigated the effect of VRT in a prospective, single center, randomised trial. Patients and methods: The 72 patients with chronic, stable visual field defects (mean patient age 57; 30 women; 95% stroke) were randomly assigned to either VRT (6-months pc-based daily visual field therapy, n=53) or control (n=23). The primary outcome variable was improvement of visual performance as measured by the detected number of visual field stimuli.…
