Localizing retrochiasmal visual field defects

Defect	Localization	Associated symptoms, signs
Homonymous sectoranopia	Lateral geniculate body	Optic atrophy, hemianesthesia, hemiparesis
Homonymous pie-in-the-sky	Anterior temporal lobe	Receptive aphasia (dominant hemisphere)
Homonymous quadrantanopia	Posterior optic radiations, visual cortex	Hemisensory loss, depending on lateralization: hemineglect Gerstmann's syndrome
Homonymous paracentral scotomas	Posterior primary visual cortex	Isolated symptom
Macular-sparing homonymous hemianopia	Primary visual cortex (sparing posterior portion)	Isolated if occipital lobe
Temporal crescent only	Far anterior primary visual cortex	Often isolated symptom
Temporal crescent-sparing homonymous hemianopia	Primary visual cortex (sparing far anterior portion)	Isolated symptom
Bilateral homonymous hemianopia	Bilateral posterior optic radiations or primary visual cortex	Anton's syndrome
