Clinical trials: Visual Field Defect Homonymous Bilateral
Hemianopia, Homonymous, Tunnel Vision
Feasibility Tests for Various Prism Configurations for Visual Field Loss
The investigators will develop and test different configurations of high-power prisms to expand the field of vision of patients with visual field loss to assist them with obstacle detection when walking.

Visual Field Defect Homonymous Bilateral
Neurofeedback-based Visual Restoration Therapy
Visual field defects are a common consequence of acquired brain injuries and affect people of all ages. These vision problems make everyday life more difficult-for example, when reading, driving, or moving around safely.

Visual Field Defect, Peripheral, Stroke
Improving Visual Field Deficits With Noninvasive Brain Stimulation
This is a randomized, pilot interventional study in participants with visual field deficit (VFD) caused by cortical lesion. Damage to the primary visual cortex (V1) causes a contra-lesional, homonymous loss of conscious vision…
