To determine the efficacy of unilateral lateral rectus recession (ULR) for convergence insufficiency-type intermittent exotropia (CI-type IXT), we compared surgical outcomes following ULR and recess‒resect (RR) procedures for CI-type IXT. In this retrospective study, medical records of 57 children who underwent ULR (n = 30) or RR (n = 27) for CI-type IXT of less than 25 PD at distance with a postoperative follow-up of 6 months or more were reviewed. Surgical success was defined as an alignment between 10 PD exodeviation and 5 PD esodeviation at distance and near fixation. The postoperative exodeviation showed no significant difference between the two groups at the last follow-up. A significant reduction in the mean near-distance difference was achieved postoperatively in both groups: from 5.4 PD preoperatively to 2.5 at last follow-up after ULR, and from 8.2 to 2.4 after RR (both p = 0.001). However, this difference between ULR and RR was not statistically significant (p > 0.05). The success rate at the last follow-up was 63.3% for ULR and 70.4% for RR (p = 0.574). ULR was found to be an effective treatment for CI-type IXT, with similar surgical outcomes to RR.

Article Synopsis
- * After one year, 31.6% of 152 subjects showed improvements in eye alignment and visual capabilities following daily patching for 2 hours.
- * Key factors linked to better outcomes included having convergence insufficiency, poor distance stereo vision, and larger angles of exo-deviation, suggesting that this treatment could be a viable non-surgical option for certain cases.
Comparison of bilateral medial rectus plication and resection for the treatment of convergence insufficiency-type intermittent exotropia.

Purpose: To compare the clinical outcomes of bilateral medial rectus plication and resection for the treatment of convergence insufficiency (CI)-type intermittent exotropia (IXT).
Methods: Fifty-five patients with CI-type IXT were included in this prospective study and were followed for 6 months. The patients were randomized into two groups: the bilateral medial rectus plication (BMRP) group (n = 27) and the bilateral medial rectus resection (BMRR) group (n = 28).

Background: The aim of this study was to investigate the type of exotropia (XT) based on the distance-near (D/N) difference in recurrent XT after bilateral lateral rectus (BLR) recession to treat intermittent XT (IXT) to look into the possibility of secondary convergence insufficiency (CI)-type strabismus.
Methods: A total of 121 patients with recurrent XT after BLR recession for basic-type and divergence excess (DE)-type IXT were retrospectively enrolled at a single institution. The distributions in the XT types were compared according to the D/N difference between primary and recurrent XT.

Aims: To compare prospectively the surgical outcomes of different surgery procedures for convergence insufficiency (CI)-type intermittent exotropia (IXT) in children.
Methods: Forty-five children with CI-type IXT were included in this prospective surgical study with 6 months follow-up. According to the different surgical procedures, all children were randomly divided into three groups: the unilateral medial rectus resection (UMR) group (15 cases), the bilateral medial rectus resections (BMR) group (14 cases) and the improved unilateral recession-resection (R&R) group (16 cases).
