“…2,22,23,24,25 It has been claimed that recession of the medial rectus is more effective, resection has an auxillary role, and when the two are performed together, it increases the effectiveness of recession by 25%. 2,25 Hopker and Weakley 26 found a mean correction of 3 PD/mm of medial rectus recession, with no significant correlation between the dose-response curve and age at surgery or deviation angle. On the other hand, Kushner et al 24 stated that preoperative deviation angle was important in infantile esotropia patients’ response to surgical dosage.…”

Objectives:To evaluate the results of symmetric and asymmetric surgery and responses to surgical amounts in patients with infantile esotropia.Materials and Methods:The records of patients with infantile esotropia who underwent bilateral medial rectus recession (symmetric surgery) and unilateral medial rectus recession with lateral rectus resection (asymmetric surgery) were analyzed. The results of the cases with symmetric (group 1) and asymmetric (group 2), successful (group 3) and failed (group 4) surgeries were compared, and responses to the amount of surgery were investigated.Results:There were no significant differences between group 1 (n=71) and group 2 (n=13) cases in terms of gender, refraction, preoperative distance deviation, anisometropia and postoperative deviation angles, binocular vision, surgical success or follow-up period (p>0.05). The rate of amblyopia, near deviation and amount of surgery were higher in group 2 cases (p<0.05). Between group 3 (n=64) and group 4 subjects (n=20), no significant differences were detected in terms of gender, surgical age, refraction, amblyopia, anisometropia, preoperative deviation angles, the number of symmetric and asymmetric surgeries, the amount of surgery, or postoperative binocular vision (p>0.05). The average postoperative follow-up period was 15.41±19.93 months (range, 6-98 months) in group 3 cases and 40.45±40.06 months (range, 6-143 months) in group 4 cases (p=0.000). No significant difference was detected in the amount of deviation corrected per 1 mm of surgical procedure between the successful cases in the symmetric and asymmetric groups (p>0.05).Conclusion:Symmetric or asymmetric surgery may be preferable in patients with infantile esotropia according to the clinical features. It is necessary for every clinic to review its own dose-response results.

“…As in other studies, 15,22,24,26 the deviation correction per mm of recession/resection was calculated by dividing the change in deviation angle by the total amount of surgical procedure. Symmetric surgery was more successful at younger ages, with the amount of correction at near and distance per mm decreasing as age increased.…”

“…MR resection can correct approximately 3 PD/mm and LR recession can correct 2.8 PD/mm of recession. 29 For large angle sensory exotropia >75 PD (rare in anisometropia) in order to avoid surgery on the dominant eye, supramaximal resection of the MR (9–11) can be combined with supramaximal recession of the LR (12–14) without significant limitation of abduction or excessive adduction and palpebral fissure changes. 30 Due to the absence of fusion, it is not uncommon for the deviation to recur.…”

“…A dose response relationship study suggested that one muscle recession can be used in XT or ET < 30 prism diopters (PD). 17 Several studies have shown that one-muscle surgery provides promising outcomes, specifically in small to moderate horizontal deviations, conversely, other studies reported a < 60% success rate. [32][33][34] Notably, most previous publications had retrospective designs.…”

Purpose: To prospectively evaluate the results of one-muscle surgery in 15-25 prism diopters (PD) horizontal comitant strabismus in adults. Patients and Methods: 15-25 PD horizontal strabismus patients, comprising 25 exotropic (XT) patients and 11 esotropic (ET) patients, who underwent one-muscle recession by a single surgeon with a fixed surgical dosage were included in the study with a minimum follow-up of 3 months. The main outcome was a surgical success, which is defined as a residual deviation of <8 PD at the last examination. Other parameters include postoperative lateral incomitance and patient satisfaction. Postoperative lateral incomitance indicated a difference in deviation of >5 PD between the primary position and lateral gaze, or duction limitation at any visit. Patient satisfaction regarding cosmetic and functional outcomes was assessed by using a 5-point Likert scale. Results: Successful alignment was obtained in 19 (76%) and 9 (81.81%) XT and ET patients (p = 1.00), with a median and interquartile range (IQR) of follow-up time of 3, 3-3 months and 3, 3-7 months, respectively. Postoperative lateral incomitance was observed in 8 (32%) XT patients and in 1 (9.09%) ET patient (p = 0.22). One XT patient and one ET patient who developed incomitance reported diplopia, which disappeared 3 months after surgery. One XT patient reported diplopia while gazing towards the operated eye whilst one ET patient reported diplopia occasionally which was unrelated to gaze direction. Patient satisfaction was based on Likert scale scores with 4.12 ± 0.97 in XT patients and 4.73 ± 0.65 in ET patients (p = 0.07). Conclusion:One-muscle recession with a fixed surgical dosage was effective for treating small angle horizontal strabismus with a high rate of surgical success and patient satisfaction. Although postoperative lateral incomitance occurred, only a few patients developed symptomatic diplopia, which completely resolved 3 months after surgery.
