Abstract

Interest in defects of the central part of the visual field was responsible for the studies in angioscotometry made in 19261 and 1927,2 and an effort to explain certain phenomena associated with these vessel shadows has resulted in the accumulation of evidence which seems to have important bearing on the interpretation of diverse pictures.

During recent years, certain anatomic and physiologic evidence has been presented which has not received the attention it deserves. Interest has been almost wholly concentrated on fiber bundles in the endeavor to account for this or that observation. In spite of the remarkable work of Igersheimer3 and others,4 knowledge of the arrangement, distribution and relations of the fiber bundles in the retina is but little more advanced than it was nearly forty years ago,5 and there has been a satisfactory understanding of the mechanism of localized areas of retinal
