[Centrally caused achromatopsia].

A 65-year-old patient sustained a transient left-sided sensomotoric monoparesis with homonymous hemianopsia. One day later there was an acute deterioration in the patient's vision and he developed achromatopsia, prosopagnosia, disturbance of spatial orientation and a homonymous upper hemianopsia. Six months later the findings are about the same. The CT shows a bioccipital lesion with left-sided accentuation, extending dorsocaudally. The origin of the cerebral infarct is presumably a vertebrobasilar insufficiency due to congestive cardiomyopathy and atrial fibrillation.
