[Examination of retinal correspondence with minimal dissociation (author's transl)].
With the phase difference haploscope the incidence of anomalous retinal correspondence in patients with convergent strabismus was examined with respect to the degree of deviation, the duration of squint and the fixation pattern of the deviated eye. Anomalous correspondence was found more often when small angles were present, in older patients and in cases with excentric fixation. Even when the deviation exceeded 19 degrees and the fixation was central, we observed harmonious anomalous correspondence in 30% of cases, The evaluation of the correspondence in children with esotropia and central fixation by means of paradoxic diplopia after correction of the deviation with prisms revealed harmonious anomalous correspondence more often than with the phase difference haploscope, although the conditions of casual seeing are changed in this test. We have attempted to ascribe these findings to simultaneous stimulation of the central retinal areas of both eyes, the nearly unlimited visual field and the short binocular exposure of the pictures in our method. Finally we described our first experiences with a modified Kongruenztest. With this simple technic it is possible to examine the state of correspondence under conditions of casual seeing.
