The occipital lobe is governed with the perception of vision. The visual cortex lies in the calcarine sulcus, and consists of the striate cortex and para-striate cortex.
Impairment of Occipital Lobe Function
A cortical lesion will result in an homonymous hemianopia with or without involvement of the macular. The more posterior the lesion will determine the degree of macular involvement.
Rarer
Anton’s Syndrome- bilateral cortical lesions will result in cortical blindness. Patient is in denial regarding his visual loss. Syndrome most likely seen in patients post strke.
