Sensorio-motorial anomalies in strabismus: (anomalous movements).
The attempts at treating anomalous correspondence by prisms in esotropia have led to the observation that frequently the angle of deviation increases with prismatic correction. The convergent movements induced by base-out prisms in esotropic patients resemble normal fusional movements in some aspects; they are provisorily called 'anomalous movements' and the objective differences between anomalous movements and normal fusional movements are reported. The strength of 'anomalous movements' are investigated with prisms. This with the aim of better understanding this sensorio-motorial sequela of strabismus and possibly selecting those patients who are more apt for prismatic therapy. The main criteria adopted today for eliminating anomalous movements and the residual postoperative deviation related with them are listed. Finally, the way anomalous movements may interfere with surgery is discussed.
