“…There was less secondary surgery required during the follow-up and no complications other than the complications seen with the classical Hang-Back technique. 19 In our study, more than 10PD esotropia was observed in nine cases (0.75%) at the end of the rst year.…”

PURPOSE:Bimedial rectus recession is one of the surgical treatment options for infantile esotropia. It is mainly performed with the Hang-Back technique, which has undesirable side effects. In this study, this technique has been modified, and its results are discussed.METHODS:The files of 120 patients followed with the diagnosis of infantile esotropia and treated bimedial rectus muscle recession using the modified Hang-Back technique were reviewed retrospectively. Cases were evaluated by the time of surgery, coexistence with inferior oblique muscle weakening surgery, and presence of refractive error. The factors investigated on the results of surgical treatment were determined as age, gender, amount of hyperopic refractive error, application age, amount of horizontal deviation, amount of recession, stereopsis, fusion, age of surgery.RESULTS:When the cases were divided into subgroups which were the time of surgery, the operation performed with inferior oblique weakening surgery and presence of refractive error; the difference between preoperative and postoperative 1st month, 6th month, and 1st-year angle of deviation was statistically significant in all three groups (p < 0.001).CONCLUSION:This novel technique aims to prevent unwanted movement of the muscle in the horizontal and vertical axis and a gap in the middle of the recessed muscle, seen in the classical Hang-Back technique. The difference between the preoperative and postoperative angle of deviation was statistically significant. Also, over and under-correction and the development of alphabetic pattern deviation were less common in our modified technique.

Bi-medial rectus recession, which can also be performed using a hang-back technique, is one of the surgical treatment options for infantile esotropia (IE). This study has modi ed the surgical approach, with outcomes compared to the traditional hang-back technique. MethodsThe bi-medial recession was performed with a modi ed hang-back technique in 120 IE patients and with a traditional hang-back technique in 88 cases. Surgical outcomes were reviewed and compared retrospectively. ResultsThe patients in the two groups were compared in terms of surgery time, inferior oblique weakening surgery, and the presence of refractive error. The differences between pre-operative deviation degrees and post-operative rst-month, sixth-month, and rst-year deviation degrees were all statistically signi cant (p < 0.001). ConclusionsThis modi ed novel technique aims to avoid unwanted muscle movement in the horizontal and vertical axes and a gap in the middle of the recessed muscle, as seen in the traditional hang-back technique.Further, the modi ed technique resulted in less over-and under-correction as well as alphabetic pattern deviation.

“…Since the popularization of the adjustment surgery in the 1970s [ 2 , 10 ], many studies have addressed adjustment and focused on introducing different adjustment techniques [ 3 , 11 , 12 ] or demonstrating the effectiveness of the adjustment technique itself by comparing surgical results between adjustment and no adjustment groups [ 13 , 14 ]. In addition, some studies focused specifically on conditions such as adjustment to thyroid-associated strabismus [ 15 ] or all types of strabismus including exotropia, esotropia, and vertical strabismus [ 9 , 16 ].…”

Background To evaluate the effectiveness of resected muscle adjustment compared with the recessed muscle adjustment in patients with intermittent exotropia. Methods This retrospective clinical investigation analyzed the data of patients who underwent strabismus surgery with adjustment. Patients who were followed-up for at least one and half year after adjustment were enrolled. They were divided into two groups; patients who underwent adjustment on recessed lateral rectus muscle (LR-Adj group) and adjustment on resected medial rectus muscle (MR-Adj group). Postoperative changes were compared. Surgical success was defined as horizontal deviation < 5 prism diopters (PD) esodeviation and < 10 PD exodeviation on distance measurement at 1.5 years postoperatively. Results Forty patients were included; LR-Adj group included 21 and MR-Adj group included 19 patients. The mean esodeviation at distance fixation immediately after adjustment was 8.1 ± 5.4 PD in the LR-Adj group and 8.4 ± 4.7 PD in the MR-Adj group (P = 0.843). Postoperative exodrift occurred in both groups, and amount of exodeviation after 1.5 year were not significantly different. For the comparison of the amount of exodrift at near measurement, the amount of exodrift within 1 month after surgery was smaller in the MR-Adj group than that in the LR-Adj group (P = 0.01). Surgical success rates were 81.0% in the LR-Adj group and 84.2% in the MR-Adj group (P = 0.559). Conclusions The smaller amount of exodrift in the MR-Adj group may mean that the positional stability of the resected muscle is favorable in the early post-adjustment period. However, there was no significant difference groups in the final exodeviation and surgical success rate between the groups. Resected muscle adjustment was as effective as the conventional recessed muscle adjustment.
