Quadrantanopia

Example of the sharp division between the blind and intact fields (for someone with hemianopsia, rather than quadrantanopia, in this case)

Quadrantanopia, quadrantanopsia, or quadrant anopia refers to an anopia affecting a quarter of the field of vision.

It can be associated with a lesion of an optic radiation. While quadrantanopia can be caused by lesions in the temporal and parietal lobes, it is most commonly associated with lesions in the occipital lobe. If Meyer's loop (temporal pathway) is lesioned, the vision loss is superior (colloquially referred to as "pie in the sky"); if optic radiation (parietal pathway) is lesioned, the vision loss is inferior.
