“…Our success rate is compatible with numerous studies. 13,25,26,28 But, the improvement amounts of deviation is slightly <23 PD obtained by Marcon and Pittino. 15 We can explain this result by the studies of Kim et al, 13 Cho and Ryu, 14 who reported the positive relationship between the preoperative deviation and the effect of the advanced muscle.…”

“…Medial rectus advancement alone may be adequate and efficient for correcting small angle consecutive XT, after recession of MR for ET. [13][14][15][25][26][27] Biedner et al 27 has suggested MR advancement alone up to the primary location for 25 PD and smaller deviations. However, in some studies 25,28 after MR advancement, it has been reported that the success rates have decreased over time and the exodeviation recurs.…”

Purpose: To compare the different surgical methods performed on a single eye in a single session and the factors that affect the success of patients having consecutive exotropia (XT) developed after esotropia surgery. Methods: The medical data of the patients who underwent surgery for consecutive XT were reviewed retrospectively. Patients with followed of 6 months or more were divided into four groups; patients with medial rectus (MR) advancement (Group 1 = 10), MR advancement and MR resection (Group 2 = 12), MR advancement and lateral rectus (LR) recession (Group 3 = 13), MR advancement, MR resection, and LR recession (Group 4 = 14). Success results and possible risk factors were investigated. Results: Forty-nine patients with consecutive XT (21 female, 28 male) were enrolled in the study. The mean age of overall patients was 22.97 years at surgery for consecutive XT. The groups did not display significant differences in terms of surgery ages, gender, refraction values, visual acuity, amblyopia, inferior oblique overaction, limitation of adduction, surgical success rates, and follow-up time ( p > 0.05). Patients of Group 4 had larger preoperative and postoperative deviation, while Group 1 had smaller ( p < 0.05). The surgical success rates of Groups 1, 2, 3, 4 were 90%, 75%, 76.9%, and 50%, respectively ( p = 0.192). Statistically, no factor was found to be effective in surgical success rates ( p > 0.05). Conclusion: Surgical treatment of consecutive XT is successful in most of the patients with numerous surgical options performed on a single eye in a single session. Patients, particularly with a high amount of deviation should be warned about the possibility of additional surgery.

“…Cooper had the principle that consecutive exotropia cases should be managed as a new case with anatomical alterations regardless of the previous esotropia surgery that had taken place. 1 While Ohtsuki et al preferred the standard reversal of the primary operation for esotropia, 20 Patel et al recommended recession of the unoperated lateral rectus muscle as it provided successful results with fewer complications, particularly in patients who did not have an adduction deficit. 21 Proper surgical management should be performed after meticulous examination, careful assessment of the type and extent of previous surgical procedures, and the presence or absence of limited adduction.…”

Purpose To compare the postoperative eye alignment in patients who underwent bilateral medial rectus advancement with those who underwent unilateral medial rectus advancement plus ipsilateral lateral rectus recession in the case of large angle consecutive exotropia without adduction deficit. Methods Thirty-four patients with large angle consecutive exotropia that developed after infantile esotropia surgery were included in this retrospective study. Nineteen patients underwent bilateral medial rectus muscle advancement (group I) and 15 underwent unilateral medial rectus muscle advancement with ipsilateral lateral rectus muscle recession (group II). The follow-up periods were at least 12 months. Postoperative eye alignment was assessed and orthotropia within 10 prism diopters was considered a successful result. Results The mean age of patients was 9.45±2.71 years in group I and 9.93±2.05 years in group II. Sixty percent of patients were female in group II and 57.89% in group I. In group I, the mean preoperative angle of deviation was 56.26±3.78 PD at distance and 53.11±3.49 PD at near. In group II, patients had a mean preoperative angle of deviation of 56±3.38 and 52.47±2.77 PD at distance and near, respectively. At the end of the follow-up period, the success rate was 52.63% in group I and 73.33% in group II (p = 0.22). The mean of the dose-effect relationship in group I was 2.62±1.35 PD/mm while in group II it was 2.36±0.84 PD/mm (p = 0.52). Conclusion In patients with large angle consecutive exotropia, unilateral medial rectus advancement combined with ipsilateral lateral rectus recession produced better postoperative eye alignment than bilateral medial rectus advancement. Group I had a higher dose-effect relationship than group II.
