PURPOSE To evaluate the outcomes of combined bupivacaine HCL (BPX) injection in the medial rectus (MR) muscle with recession of the lateral rectus muscle in the treatment of conver-gence insufficiency-type intermittent exotropia (CI-IXT).METHODS The medical records of patients who underwent combined injection-recession treatment from January 2019 to January 2020 for CI-IXT were reviewed retrospectively along with a group of age-matched controls with IXT without CI who underwent only unilateral LR recession during the same period. The following data were extracted from the record: age at surgery, average follow-up period, angle of deviation at distance and near and the difference between them before and after surgical procedure, correction of near and dis-tance deviations, and recession dosage. Successful outcome was defined as a distance devi-ation in primary gaze between <= 10 degrees of exophoria/tropia and <= 5 degrees of esophoria/tropia.RESULTS A total of 10 patients and 20 controls were included. Average follow-up was 13.9 +/- 3.67 months in the BPX group and 15.9 +/- 3.61 months in the control group (P = 0.17). Post-operative distance deviation measured 8.30 degrees +/- 5.88 degrees in the BPX group and 14.67 degrees +/- 9.83 degrees in the control group (P = 0.80). Distance-near differences were significantly reduced in the CI-IXT group receiving BPX, by a mean of 6.60 degrees, from a preoperative mean of 10.50 degrees +/- 3.65 degrees to 3.90 degrees +/- 3.26 degrees (P \ 0.01).CONCLUSIONS BPX injection combined with unilateral lateral rectus recession yields outcomes compara-ble to bilateral lateral rectus recession for distance deviations, and results in reduction of the distance-near difference in the angle of exotropia.
