Assessment and Rehabilitation of Post-Stroke Visual Field Impairments: Current Approaches and Emerging Technologies.

This article focuses on the assessment and rehabilitation of visual field defects, particularly homonymous hemianopia (HH), following stroke. It reviews traditional visual field testing methods such as static and kinetic perimetry, and rehabilitation strategies including visual substitution therapies (e.g., prisms), eye movement-based therapies, and visual restitution therapies (VRT) like border-field training, blindsight training, and brain stimulation. While these approaches show variable effectiveness, emerging technologies such as virtual reality (VR) offer promising, more accessible tools for both screening and rehabilitation by simulating real-world environments and enabling personalized training. The article highlights ongoing controversies regarding the efficacy of some therapies, especially VRT, and calls for further rigorous research to establish standardized, evidence-based protocols to improve functional recovery and quality of life for stroke survivors with visual impairments.
