[Diploptics - brand-new system of concomitant squint treatment (author's transl)]

The present paper exposes the shortcomings of orthoptics and proposes an original system of concomitant squint treatment named diploptics. This system is based on the new conception of the role of bifixation in the physiology and pathology of binocular vision. The major principle of diploptics is to induce diplopia under natural conductions and further to "enliven" or develope the ability to overcome it with the help of the optomotor fusion reflex and thus to recover the auto-control mechanism of bifixation - the basis of the normal binocular vision. To realize this principle a number of methods are suggested. A trial of these produced hopeful results.
