RESUMO
The effect of steady-state nystagmus suppression has been found upon periodic light exposure of the eye. The paper describes the exposure facility and procedure based on the changes in the amplitude and frequency of light pulse until there is a response of a patient's nystagmus parameters that are continuously monitored by video-assisted computer system. After periodic light exposures, there was a persistent suppression of nystagmus and a steady-state increase in visual acuity by an average of 0.1.

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.

The paper analyses results after treatment of patients with vertical squint (53 persons) using a principally new method--binarimetry, as one of diploptic methods. All patients had residual vertical deviation after surgical treatment or a small angle (to 10 degrees). The device and the method of treatment are described. In the most of patients, binocular vision was restored (77.3%) on account of development of vertical fusional reserves and correction of residual deviation.
