In these studies, the diagnosis of stroke was based mostly on clinical evaluation and not all patients had undergone brain imaging. Our study, which included neuroimaging in all cases, confirms these results. Homonymous hemianopia is a loss of the right or left halves of the visual field of both eyes (Figure 1a, 1b) and usually occurs as a result of a middle cerebral or posterior cerebral artery stroke affecting either the optic radiation or visual cortex of the occipital lobe (Figure 2).

Additionally, a lesion at the right lateral geniculate nucleus (postchiasmal) is expected to cause a binocular homonymous left hemianopia.
