摘要

Circumstances have only made it possible to consider in detail a few of the many cases observed over the previous 18 months in the base hospitals in France that have a bearing on the representation of different regions of the retina in the cortex. Furthermore, in studying cases soon after injury, the effects of shock or diaschi-sis may have dissociated functional deficits from those that result from structural damage. Necessarily, most of the subjects are studied in cramped beds using a hand-held perimeter; seldom is a modified Bjerrum screen (a black cloth placed over a double foolscap sheet of paper pinned to a board, with a drawing pin as the point of fixation, and held at one metre) or McHardy perimeter also used. Salomen Henschen (1847-1930) has shown that the visual cortex corresponds to the area striata with the superior half of each retina (the lower field) represented in the upper part of the occipital lobe and the inferior below and in the lips of the calcarine fissure: 'on the other hand nothing is definitely known on the correspondence between various concentric zones of the retina and the different segments of the area striata.
