[Reoperation of the internal or external rectus in case of undercorrection (author's transl)].

The present paper presents a new reoperationtechnic in case of undercorrection. First the different possibilities of surgical technics are reviewed and than the new approach outlined. Between the primary (physiological) insertion and the secondary insertion (after a conventional recession) there is usually some episcleral connective tissue formation. This tissue is carefully dissected without cutting the link between the muscle and the tongue. The secondary insertion is then cut off and the elongated muscle reattached at the secondary insertion. Pictures illustrate the procedure. This method is especially useful in case of narrow palpebral fissue, increased rigidity of the internal rectus and in case of small angle exotropia for distance.
