Visual field defect involving loss of vision in half of the visual field, commonly occurring after stroke or brain injury.
Full Definition
Hemianopia, also spelled hemianopsia, is a visual field defect characterized by blindness or reduced vision in one half of the visual field. This condition frequently occurs following stroke, traumatic brain injury, or other neurological conditions affecting the visual pathways. In rehabilitation documentation, editors encounter various types including homonymous hemianopia (same side visual field loss in both eyes) and heteronymous hemianopia (different sides affected). The condition significantly impacts functional activities such as reading, driving, and navigation, making it a critical consideration in rehabilitation planning and safety assessments.
Usage
Usage note: Both hemianopia and hemianopsia are acceptable spellings; maintain consistency within documents.
