[A diploptic method in the early treatment of concomitant strabismus in children].

In 1917 Avietisov proposed a new treatment of concomitant squint by so called diploptic method to restore the binocular vision in natural conditions. To verify this method the authors carried out examinations of children in pre-school and in school age. The extent of disturbances of the binocular vision was evaluated by means of colour filters of various dissociation. For this purpose a set of colour filters is used arranged similarly to the retinoscopy set or in a form of round discs. The children exercised on a device ensuring a smooth change of the colour filters. In result of the diploscope therapy 70.8 p.c. from among 132 patients aged 3-6 years regained the binocular vision.
