R. C. Oldfield's Study of Visual and Topographic Disturbances in a Right Occipito-Parietal Lesion of 30 Years Duration.

A short account is given of a case of right occipito-parietal abscess first studied by Oldfield in 1939 and followed up over a period of 30 years. The main disabilities lay in the sphere of spatial orientation and visual memory and underwent little substantial change over this period. None the less, appreciable re-adaptation was achieved by compensatory measures. Some theoretical issues are briefly touched upon.
