“…Undercorrection or recurrence was defined as an alignment of > 10 PD of exotropia, and overcorrection was defined as > 10 PD of esotropia [4, 12]. A stereoacuity of 100 s of arc or better was defined as good.…”

“…Surgical options for patients who have undergone bilateral medial rectus resection (BMR) include bilateral medial rectus re-resection, unilateral lateral rectus recession and medial rectus re-resection, and bilateral lateral rectus recession (BLR). However, rectus muscle reoperation has disadvantages because it is a more difficult surgical technique due to scar tissues, it requires more time under anesthesia, and it has a higher risk of limited ocular rotation [4, 10]. Therefore, BLR, as the secondary operation, may achieve satisfactory results for this condition.…”

Purpose: To evaluate the efficacy of bilateral lateral rectus muscle recession (BLR) to treat recurrent exotropia after bilateral medial rectus muscle resection (BMR). Methods: Twenty-four patients who underwent BLR for recurrent exotropia and were followed up for more than 6 months were included in this retrospective study. All of them had prior BMR. The angle of deviation, success rates, near stereopsis, and surgical effect of BLR were evaluated. Surgical success was defined as postoperative deviations ≤10 prism diopters (PD). Results: The overall mean follow-up time after reoperation for patients was 24.13 ± 15.01 months (range 6–60 months). The mean angle of deviation at distance was significantly reduced from –37.75 ± 14.93 PD to +1.50 ± 6.43 PD (p < 0.001). Twenty-two (91.6%) of 24 patients had successful outcomes, 1 (4.2%) had overcorrection, and 1 (4.2%) had undercorrection at the last follow-up. Improved stereopsis after reoperation was observed in 78.3% (18/23) of the patients. The mean surgical effect was 2.78 ± 0.71 PD/mm. Conclusion: Based on our results, BLR could be an effective and safe method for treating recurrent exotropia after a moderate to large amount of BMR.

“…Esotropia is a common condition in children and in many cases surgery on the extraocular muscles is necessary to achieve normal ocular alignment. Despite being a well-established and effective treatment for esotropia [1][2][3][4][5][6], recurrent and residual esotropia are still quite common [5,6]. Residual or recurrent esotropia was reported in 20-40% of the patients [3].…”

Purpose To assess the surgical outcomes of reoperations for residual and recurrent esotropia. Methods A retrospective chart review of all patients who underwent surgery during 2000-2017 at a tertiary referral medical center for recurrent or residual esotropia was conducted. Patients who underwent bilateral medial rectus recession as primary surgery and lateral rectus resection as second surgery were included. The success rate of second surgery and its association to various factors were examined. Success of reoperation was defined as mean deviation of \ 10 prism diopters (= PD) at last follow-up. Results Twenty-seven patients with mean post-operative follow-up of 50.4 ± 31.7 months were included. On last follow-up examination, 15 (55.6%) patients had a successful reoperation and 12 (44.4%) patients had unsuccessful reoperation. The two groups were similar in the pre-operative amount of esotropia for distance and near. On last follow-up examination, the amount of mean deviation was 1.9 PD esotropia (8 PD exotropia to 9 PD esotropia) in the success group and 11.2 PD esotropia (22.5 PD exotropia to 35 PD esotropia) in the failure group. In the failure group, 75.0% of patients were under-corrected (esotropia of C 10 PD) on last follow-up examination. Conclusion Strabismus reoperation in cases of residual or recurrent esotropia was successful in slightly more than half of the patients. Surgical failure was more commonly associated with undercorrection and less with overcorrection.

“…Published articles have reported outcomes of residual or recurrent exotropia treated with a unilateral medial rectus (UMR) resection, bilateral medial rectus (BMR) resection, unilateral lateral rectus (ULR) recession, contralateral recess-resect and bilateral lateral rectus (BLR) re-recession with rates of success ranging from 60% to 100%. [2][3][4][5][6][7][8] There are also studies suggesting one muscle surgery for residual esotropia. One such study investigated resection of a single muscle with the surgical dosage calculated by doubling the angle of strabismus and applying the recommended surgical dosage to one lateral rectus muscle.…”

Purpose: To report the results of bilateral lateral rectus muscle recession for recurrent exotropia in cases where the primary surgery was a bilateral medial rectus resection. Methods: Retrospective chart review of 15 subjects who completed 6 months of follow-up. Data collected included patients’ demographics and pre- and post-operative measurements of ocular alignment and motility. Surgical nomogram used was the same nomogram we use for primary cases of exotropia. Results: At 6-month follow-up, 73.3% of cases had a successful surgical outcome (defined as 8 PD of esotropia to 10 PD of exotropia). In addition, recession of lateral rectus muscles against the previously resected medial recti did not result in a significant increase in the limitation of abduction. Conclusion: Bilateral lateral rectus recession using standard surgical tables is a safe and effective method for treating recurrent exotropia following bilateral medial rectus resection. Even large primary resections up to 12 mm do not seem to affect the results of bilateral lateral rectus recession.
