Quadrantanopia (or quadrant anopia, as two words) refers to an anopia affecting a quarter of the field of vision.

It can be associated with a lesion of an optic radiation. [ [http://www.med.yale.edu/caim/cnerves/cn2/cn2_11.html Yale- Cranial Nerve 2, pg. 11 ] ] If Meyer's loop is lesioned, the vision loss is superior; if the parietal path is lesioned, the vision loss is inferior.
