[5] A lesion affecting one side of the temporal lobe may cause damage to the inferior optic radiations (known as the temporal pathway or Meyer's loop) which can lead to superior quadrantanopia on the contralateral side of both eyes (colloquially referred to as "pie in the sky"); if the superior optic radiations (parietal pathway) are lesioned, the visual loss occurs on the inferior contralateral side of both eyes and is referred to as an inferior quadrantanopia.

[6] Binasal (either inferior or superior) quadrantanopia, also known as Nerurkarian field defects affects either the upper or lower inner visual quadrants closer to the nasal cavity in both eyes.

Bitemporal (either inferior or superior) quadrantanopia affects either the upper or lower outer visual quadrants in both eyes.

[citation needed] Individuals with quadrantanopia often modify their behavior to compensate for the disorder, such as tilting of the head to bring the affected visual field into view.

[8] Teaching individuals with quadrantanopia compensatory behaviors could potentially be used to help train patients to re-learn to drive safely.
