Academic Hemianopia and the Treatment of Cerebrovascular Disease

  • M. D. O’Brien
Conference paper


The term academic scotomata has often been used to describe defects in our perception of problems and the analogy can be extended to a variety of field defects, including tunnel vision. Hemianopic defects can be of several sorts, of which the commonest is probably the extrapolation of graphs beyond the data. This paper considers the often erroneous assumption that if a problem is caused by too little of something, then more of it must be beneficial.
