lesions of the occipital lobe may cause four things
• paroxysmal visual hallucinations of a simple, unformed nature, e.g. lights or colours
• contralateral visual field loss (contralateral homonymous hemianopia)
- Rare bilateral lesions of the occipital lobe (due to stroke or head injury) may lead to cortical blindness of which the patient is unaware (Anton’s blindness or Anton-Babinski syndrome)
-Bilateral parietooccipital lesions may spare elementary vision, but prevent the recognition or depiction of objects
(apperceptive visual agnosia).
