To evaluate the surgical efficacy of bilateral lateral rectus recession (BLRR) for intermittent exotropia with convergence insufficiency (CI-type X[T]). The medical records of patients with CI-type X(T) who underwent BLRR on adjustable suture from January 2011 to March 2014 were retrospectively reviewed. Ocular alignment and sensory status were evaluated pre- and postoperatively for each patient. The mean distance and mean near deviation, before and after surgery, as well as the mean near-distance difference, were compared. Success was defined as postoperative alignment of esophoria/tropia of ≤5(Δ) and exophoria/tropia of ≤8(Δ) at distance. A total of 25 patients were included. The mean exodeviation was significantly reduced, from 32.5(Δ) preoperatively to 0.08(Δ) postoperatively (P<0.001) at distance and from 45(Δ) preoperatively to 2.4(Δ) (P<0.001) postoperatively at near. The mean near-distance difference was reduced from 16(Δ) preoperatively to 2(Δ) postoperatively (P<0.01). Of the 25 patients, 21 (84%) obtained successful motor alignment, 2 had recurrent exodeviation of ≥10(Δ) at distance, and 2 had overcorrected esotropia with deviation angles of >8(Δ). In this cohort of patients, bilateral lateral rectus recession using an adjustable suture technique successfully treated CI-type X(T).
