Rectus Muscle Weakening Procedures
Table 14-3 defines various rectus muscle weakening procedures and describes when each is used. The most common is simple recession (Video 14-3), for which typical amounts of surgery for esotropia and exotropia are given in Tables 14-1 and 14-2, respectively. Because the conventional technique for rectus muscle recession involves passing sutures within thin sclera with the attendant risk of perforation, some surgeons prefer a hang-back recession, in which the recessed tendon is suspended by sutures that pass through the thicker stump of the original insertion. Although it is not known where the tendon reattaches to the sclera, empirical experience indicates that this method is usually reliable.
