[Examination of stereoscopic vision with the phase-difference haloscope (author's transl)].

The authors report on the possibilities for examination of the stereoscopic vision at 2 or 4 meters by the phase-difference-haploscope. Besides a gross-qualitative test, methods of estmating realdepth acuity are described. There is a great variability of test-conditions for special scientific problems. During the routine examintion of disturbed binocular vision it is possible to test the stereo acuity, even if there is squint or aniseiconia.
