WebKey points. The visual pathway comprises the retina, optic nerve, optic chiasm, optic radiations, and the visual centre in the occipital lobe. Optic nerve lesions tend to cause ipsilateral monocular blindness. At the optic chiasm, fibres from the nasal half of the retina, corresponding to the temporal visual field, decussate. WebMar 10, 2024 · The rods function mainly in dim light and are responsible for black-and-white vision. The cones function best in bright light and are responsible for colour vision. ...
