[Eye-hand coordination in squint sufferers].

The localisation of an object close at hand and grasping it with the hand is the result of a complicated sequence of nerve impulses involving close co-operation between optical, perceptive and psychological stimuli, which are integrated in the central nervous system and lead to a well-directed command-movement. Disturbances of coordination between eye and hand in cases of amblyopia and concomitant strabismus are described. The individual authors suggest different forms of traeatment. In our opinion these are not genuine disturbances of hand-eye coordination. In amblyopia we have an ambiguity of localisation due to fact that the fixation is not stable. In the case of strabismus the error of spatial localisation can be explained by the unnatural examination methods, and by the abnormal position of the eye in the orbit. There is no denying the results gained by localisation treatment, but these the results can also be achieved by another mechanism not only in amblyopia but also in strabismus.
