Detailed explanation-1: -PCA strokes will primarily cause a visual field loss or homonymous hemianopia to the opposite side. This large occipital or PCA stroke causes people to be “blind” on one side of the visual field. This is the most common symptom of a large occipital lesion or PCA stroke.
Detailed explanation-2: -The posterior cerebral artery curls around the cerebral peduncle and passes above the tentorium to supply the posteromedial surface of the temporal lobe and the occipital lobe. The visual cortex responsible for the contralateral field of vision lies in its territory.
Detailed explanation-3: -Cognitive changes resembling a global dementia may occur and be accompanied by incontinence. Residual personality changes of a frontal type can occur. Posterior cerebral artery occlusion presents with a contralateral hemianopia sometimes accompanied by visual hallucinations, visual agnosias or spatial disorientation.
