Damage to the posterior cerebrum can affect vision and visual perception. This may be manifested as cortical blindness or Balint's syndrome.
Cortical blindness (Anton's syndrome)
(1) secondary to deficiency in the posterior circulation
(2) occurs with bilateral damage to the occipital lobes
(3) blindness
(4) accompanied by denial of blindness
Balint's syndrome:
(1) associated with bilateral lesions anterior to the primary visual cortex, either in the posterior parietal or anterior occipital lobes
(2) visual acuity is intact
(3) ocular apraxia is present (unable to use vision to control intended movements of the hands)
