Abstract
ABSTRACT Lateral heterophoria values have been measured sequentially by means of a computer controlled stepping prism. Von Graefe's method, with minor modifications, was used. A modification of this method is shown by which phoria variations can be followed, starting from the break of fusion. These subjective measurements of heterophoria show characteristics that would not be revealed by a single measuremnt.
