Rectus Muscle Tightening Procedures
Although also referred to as strengthening procedures, muscle tightening procedures (defined in Table 14-4) do not actually give the muscles more strength. Rather, they produce a tightening effect that tends to offset the opposite action of the antagonist muscle. For this purpose, surgeons usually use the resection technique (Video 14-4); typical amounts of surgery for esotropia and exotropia are given in Tables 14-1 and 14-2, respectively. Plication of the muscle can be used as an alternative to produce a similar effect. A previously recessed rectus muscle can also be tightened by advancing its insertion toward the limbus.
