Efficacy and predictors of recovery of function after eye movement training in 296 hemianopic patients.

Compensatory approaches to rehabilitation of vision loss as a result of brain injury are aimed at improving the efficacy of eye movements, enabling patients to bring the otherwise unseen stimuli into their sighted field. Eye movement training has shown promise in a large number of studies in small clinical populations. Nevertheless, there remain two problems; standardisation and wide accessibility.

Combining visual rehabilitative training and noninvasive brain stimulation to enhance visual function in patients with hemianopia: a comparative case study.

Objective: To standardize a protocol for promoting visual rehabilitative outcomes in post-stroke hemianopia by combining occipital cortical transcranial direct current stimulation (tDCS) with Vision Restoration Therapy (VRT).

Design: A comparative case study assessing feasibility and safety.

Setting: A controlled laboratory setting.

Visual field changes after a rehabilitation intervention: vision restoration therapy.

Background: The objective of this study was to determine the effect of a visual rehabilitation intervention on visual field defects in a US cohort. Vision Restoration Therapy (VRT) consists of a specific pattern of stimulation that is directed at the border of the blind field.

Methods: This retrospective study evaluated individuals with homonymous visual field defect from retrochiasmatic lesions treated with 6 modules of VRT.

Vision restoration therapy (VRT) efficacy as assessed by comparative perimetric analysis and subjective questionnaires.

Purpose: We wished to evaluate the efficacy of vision restoration therapy (VRT) in patients with post-chiasmatic brain damage using different functional perimetric tests. These were compared with measures of subjective vision and reaction time.

Methods: An open trial was conducted with hemianopia/scotoma (n=16) patients.
