  • Title: [A case of central homonymous hemianopsia due to cerebral infarction of the occipital tip].
    Author: Kiriyama K, Yoshimura T, Furuya H, Kobayashi T, Hasuo K.
    Journal: Rinsho Shinkeigaku; 1996 Jul; 36(7):902-5. PubMed ID: 8952363.
    Abstract:
    A 54-year-old man was admitted to the hospital because of the restriction of the right visual field. Goldmann's visual field test revealed the right central hemianopsia. MRI showed the infarction of the left occipital lobe tip. Cerebral angiography showed the occlusion of the left calcarine artery but no abnormality in the branches of the middle cerebral artery (MCA). The occipital lobe tip receives the projection from the macular area and is supplied by both calcarine artery and a branch of MCA. Therefore, cases of central homonymous hemianopsia due to vascular disorders have been relatively rare and the macular vision is usually spared. In contrast to the above knowledge, only one artery occlusion resulted in the central hemianopsia in our case. Poor anastomosis between PCA and MCA in the occipital tip of our patient may explain occurrence of the infarction of that area.
