Surgical Outcomes of Medial Rectus Recession and Lateral Rectus Resection for Large-angle Deviations of Acute Acquired Concomitant Esotropia.

Abstract

PURPOSE:

This study aimed to evaluate the surgical outcomes of unilateral medial rectus recession and lateral rectus resection (R&R) for patients with large-angle deviations of acute acquired concomitant esotropia (AACE) without a neurological disease. Further, we have also suggested the surgical dosage of R&R for large-angle deviations of AACE.

METHODS:

This was a retrospective study of patients with AACE who underwent surgery and followed up after surgery for at least 6 months between September 2016 and March 2020. Among them, patients with ocular deviations of ≥30 prism diopters (PD) who underwent unilateral R&R were included.

RESULTS:

Seventeen patients with AACE were enrolled in this study (mean age, 23.5 years; four females). The mean amount of deviation was 40.00 PD at distance and near (range, 30-55 PD). Fifteen patients (88.2%) had myopia. The mean interval between the initial visit and surgery was 7.7 months (range, 4-20 months). All included patients had resolved diplopia after the surgery. Most patients with decreased stereoacuity displayed stereoacuity recovery after surgical treatment. At the final visit (mean follow-up period, 12.8 months), the mean angle of esodeviation was 0.82 PD (range, 6-0 PD) at distance and 0.47 PD (range, 4-0 PD) near. No patient displayed over-correction or adduction limitations in the operated eye.

CONCLUSIONS:

The unilateral R&R procedure presented favorable surgical outcomes for patients with large-angle deviations of AACE. These results and proposed surgical dosage guidelines may be useful for surgeons in planning the surgical treatment of large-angle deviations of AACE.
