[Elucidation of the possibilities for muscle transplantation in paralytic esotropia. Electromyography of the superior and inferior rectus muscles].
The activity of superior and inferior rectus muscles of the eye in a gaze upwards, downwards, to the right, to the left and in primary position has been electrographically determined in 13 adults without disturbances in eye motility. The analysis of the results obtained has shown that there doesn't exist adducent action of these muscles as an active physiologic function. Anatomically conditioned, but practically low and weak, adducent action of the muscles, being passive by nature, can be in norm caused by the weakening of the external rectus muscle in adduction of the eye, because in horizontal moving it preserves the level of activity characteristic for primary position of the eye. One must think that after surgical correction of paralytic esotropia by methods changing the vector of action of superior and inferior rectus muscles for restoration of adduction, the desired action of the transplanted muscles is passive and low (to 6-8 degrees).
