Long-term follow-up study on surgical outcomes of the Faden operation in consecutive esotropia

Abstract

AbstractWe evaluated the long-term surgical outcomes of medial rectus (MR) recession with the Faden operation in consecutive esotropia (CET). We retrospectively analyzed patients who underwent MR recession with the Faden operation for CET between 2013 and 2018, and compared surgical outcomes between patients who underwent MR recession with the Faden operation (Faden group) and MR recession only (control group). We followed up the patients at 24 months postoperatively. Postoperative success was defined as final deviation of less than distant 5 prism diopters (PD) of eso- or exodeviation at the final visit. We compared postoperative alignment and stereoacuity between the two groups. Stereoacuity was classified as good (60 or better seconds of arc), fair (80–3000 s of arc) or nil. The Faden and control group included 11 and 13 patients, respectively. All patients in the Faden group showed orthophoria and eight patients (72.7%) showed good stereoacuity at the final visit. One patient (9.1%) in the Faden group showed adduction limitation at the final visit. Eight patients (61.5%) in the control group had successful outcomes at the final visit. Six patients (46.2%) in the control group showed good stereoacuity at the final visit. One patient (7.7%) in the control group underwent reoperation for recurrent esotropia at 18 months postoperatively. The surgical outcomes after MR recession with the Faden operation for CET were excellent in long-term follow- up. The Faden operation could be a good surgical option for CET.
