Left Occipital Lobe
Remember
Nasal fibers are meant to relay the temporal visual field and vice versa
So in the following picture, the following findings are observed
- Right Temporal hemianopia with Macular Sparing
- Left Nasal hemianopia with macular sparing
So they collaborate with Left Occipital Lobe involvement - As Left Temporal fibers and Right Nasal Fibers would be involved
Posterior Cerebral artery lesion with the middle cerebral artery sparing leads to the macular
sparing feature. Middle cerebral artery supplies the tip of the occipital lobe.
