[Study of binocular vision by the binary metric method].

The authors describe a method for binocular vision studies with the use of spatial visual effects emerging when double images are fused in physiologic diplopia. Various forms of binocular cooperation were detected and a clinical classification of these forms developed, based on the ability to obtain a binocular visual image. One of the distinctions of the suggested method is the detection of not only binocular fusion, but of the ability to in-depth perception. The authors analyze the status of binocular function in subjects with various forms of binocular sensor cooperation, basing on binary metric data and the findings of the color test and synaptophore studies. Binocular cooperation impairments, detected by binary-metry, appear less severe than if detected by the color test or synaptophore studies in the same patients.
