[Anomalous fusional movements: the sensorimotor aspect of anomalous binocular vision (author's transl)].

It has been demonstrated that, besides sensory adaptation phenomena, sensorimotor phenoma may also develop in concomitant esotropia. The existence of the latter entity can be shown particularly by means of prisms and is interpreted as fusional in origin. It is therefore defined as 'anomalous fusional movements'. The features of these anomalous fusional movements were studied in a group of 30 patients, mainly in order to investigate their finality. Correlations were evaluated between anomalous fusional movements and entities previously described by different names according to the interpretation given them by various authors.
