A case is reported of a patient who, following a transient left hemisphere ischemia, developed a pure alexia, associated with right homonimous hemianopia and color anomia. The patient presented no evidence of aphasia and no disturbance of writing but showed a clear literal alexia, and could read only by using his finger to trace the outline of each letter. Furthermore, he showed a complete inability to name colors on presentation and some difficulties in properly selecting colors when the name was given, although he could accurately match colors of different brightness and saturation. He had no difficulty in handling color names at a strictly verbal level. These symptoms were accompanied by additional findings of defective visual recognition, such as difficulty in copying simple geometric figures, or in identifying objects or pictures on visual presentation. Some implications of these findings are discussed, with reference to the models of visual agnosia and visual verbal disconnection.
