Purpose. To evaluate the surgical outcomes of unilateral or bilateral medial rectus (MR) muscle resection for recurrent exotropia after bilateral lateral rectus (BLR) muscle recession based on a novel surgical formula. Methods. Forty-one consecutive patients with unilateral or bilateral MR muscle resection for recurrent exotropia after BLR muscle recession were included in this retrospective study. All surgeries were performed according to the formula: 1.0 mm MR muscle resection for every 5 prism dioptres (PD) of exotropia, with an addition of 0.5 mm to each MR muscle operated on. Results. The mean recurrent exotropia distant deviation was 28 PD ± 11.2 (range 14 to 55 PD). Overall at postoperative 1 month, 36 (88%) achieved successful outcomes, 4 (10%) had undercorrection, and 1 (2%) had overcorrection. At postoperative 6 months, 29 (71%) achieved successful outcomes, 12 (29%) had undercorrection, and none had overcorrection. Subgroup analysis showed no statistically significant difference in success rates between unilateral and bilateral MR groups. Conclusion. Unilateral or bilateral MR muscle resection using our surgical formula is a safe and effective method for calculating the amount of MR resection in moderate to large angle recurrent exotropia, with a low overcorrection rate.

Background And Objective: There is no strict by-the-book rule as to which approach is the best strabismus surgery for patients with sensory exotropia. More commonly, a monocular lateral rectus recession and a medial rectus resection (monocular R & R; MRR) is performed in the eye with a poorer prognosis. Rarely, for larger deviations, a third or fourth horizontal muscle in the better eye is added.

In cases of recurrent exotropia, medial rectus resection after bilateral lateral rectus recession is often considered for reoperations. The surgical amount of medial rectus resection is typically determined according to the standard surgical dose table; however, postoperative variability has been noted in the surgical outcomes. In the current study, medial rectus tendon width (MRTW) was measured intraoperatively, and surgical dose-response was calculated as the ratio between amount of correction and resected medial rectus.

To assess the response to monocular occlusion test in basic type intermittent exotropia (IXT) and to evaluate the surgical outcomes of titrated surgery based on the test's result. Medical records were retrospectively reviewed for patients who underwent bilateral lateral rectus recession for basic type IXT. Patients were categorized into two groups: those who underwent a preoperative diagnostic monocular occlusion test (occlusion group) and those who did not (no occlusion group).
