When there is loss of part of the usual field of vision it is known as a visual field defect. Damage anywhere along the visual pathway from the retina to the occipital lobe can result in visual field defects.

Damage along the optic pathway causes a variety of visual field defects. The type of field defect can help localize the lesion (see table Types of Field Defects). Higher Visual Pathways—Lesion Sites …

Feb 5, 2024 · Visual field defects can arise from multiple different pathologies throughout the visual pathway, and the type of defect can provide important links about the underlying pathology.

Although we generally measure and display the visual field one eye at a time, it is important to remember that the visual fields from the right and left eyes actually overlap. Motor systems …
