"WebbWithin the layers of the retina, light impulses are changed into electrical signals. Then they are sent through the optic nerve, along the visual pathway, to the occipital cortex at the posterior (back) of the brain. Here, the electrical signals are interpreted or “seen” by the brain as a visual image. " - The pathway of vision

Visual loss is a serious clinical problem, commonly presenting first to non-ophthalmic healthcare professionals. It typically describes a reduction in visual acuity (sharpness/clarity) or field. This may be acute- or gradual-onset, monocular or binocular and transient or permanent, and may affect central and/or peripheral vision.
