As indicated by the title, this discussion is a more or less detailed presentation of the steps in orthoptic training necessary to restore single binocular vision in cases of squint. Although many observers are disposed to doubt the results which have actually been obtained in several cases, interest in the subject is growing, and many authors are adding their contributions in support of these claims.
I was invited to discuss technic rather than results, but before the details of treatment are considered several basic facts should be stated in the form of a premise which in my personal experience, as well as in that of others who have given much time and thought to the training for the overcoming of squint, seems to be established as logical conclusions.
The facts which I wish to emphasize are:
In true alternating squint a faculty for fusion is not present and cannot
