RATIONALE Occlusive cerebrovascular disease is the most common cause of homonymous hemianopia (HH) with macular sparing. PATIENT CONCERNS A 61-year-old man came to our ophthalmology clinic complaining of right-side hemianopia. Ophthalmic examination, visual field (VF) examination, and brain magnetic resonance imaging (MRI) were performed. DIAGNOSES He had right HH without macular sparing on...

AIM To examine whether visual restitution training (VRT) is able to change absolute homonymous field defect, assessed with fundus controlled microperimetry, in patients with hemianopia. METHODS 17 patients with stable homonymous visual field defects before and after a 6 month VRT period were investigated with a specialised microperimetric method using a scanning laser ophthalmoscope (SLO). Fi...

Occipital stroke is associated with visual field defects and other perceptual deficits that might lead to detrimental effects on health-related quality of life. This study aimed evaluate the possible association between systemic risk factors features occipital stroke.

In the late 19th century, Déjérine first described this entity in a man with associated incomplete right homonymous hemianopia from a lesion of the left fusiform and lingual gyri. He subsequently deduced that the left angular gyrus stored the visual representation of words (needed for reading and writing), and that disconnecting the visual inputs of both hemispheres from the left angular gyrus ...

We report on a right-handed, deaf, life long signer who suffered a left posterior cerebral artery (PCA) stroke. The patient presented with right homonymous hemianopia, alexia and a severe sign comprehension deficit. Her production of sign language was, however, virtually normal. We suggest that her syndrome can be characterized as a case of 'sign blindness', a disconnection of the intact right ...
