Faden operation in consecutive esotropia

초록

Purpose To evaluate the efficacy of Faden procedure for correcting consecutive esotropia (ET). Methods This retrospective study included 25 children who developed consecutive ET after primary bilateral lateral rectus (BLR) recession and underwent medial rectus (MR) recession with the Faden procedure (Faden group) or MR recession only (control group) between 2013 and 2018. Postoperative deviation angles were evaluated at each follow-ups until postoperative 6-month visit. Surgical motor and sensory outcomes were compared between Faden group and control group. Results There were 10 children in the Faden group and 15 children in the control group. While the Faden group maintained orthotropia without any small deviation until postoperative 6-month visit, the control group showed wider distribution of postoperative deviation angles (1 patient with small angle esodeviation < 5 PD, 3 patients with esodeviation > 5 PD, and 3 patients with exodeviation < 5 PD). In the Faden group, seven patients have good stereopsis (60" or better) and three patients demonstrated fair stereopsis (80-3000") after surgery. In the control group, four, eight, and three patients showed good, fair, and nil stereopsis (P = 0.026), respectively. Conclusion MR recession combined with Faden operation could be a good surgical option for managing consecutive ET.
