Abstract
<h3>To the Editor:</h3> —Central and peripheral fusion is now a live subject, and Dr. J. E. Winkelman's stimulating contribution in the August 1953 issue of theArchivesis a welcome addition. There are, however, a few points in the article which are a bit obscure and which may need clarification by the author. I shall touch upon only one point. In his experiments on peripheral retinal rivalry, or fusional movements, the author presented two different targets to the temporal halves, and also to the nasal halves, of the two eyes. But these regions are not corresponding regions and would show neither retinal rivalry nor fusion. The innate directional values of the retinal elements in the right temporal retina are toward the left side of the visual field, while the innate directional values of the retinal elements in the left temporal retina are toward the right side of the visual field.
