Intermittent exotropia: comparative surgical results of lateral recti-recession and monocular recess-resect

Comparison of bilateral lateral rectus recession and unilateral recession resection for basic type intermittent exotropia in children

“…The results of this study are in agreement with the Kushner4 and Audery7 studies that R&R is more effective than BLR-rec. Furthermore, the undercorrection rate in patients who had undergone BLR-rec was 23.7% (9/38) in our study, similar to Fiorelli's result of 28.6%6 and Choi's result of 21.8% (1-year follow-up),8 but lower than Audery's result of 56% 7. According to our study, it seems that BLR-rec tends to lead to a lower surgical success rate and a higher probability of undercorrection, increasing the risk of reoperation.…”

“…In different studies, the success rate of treating basic type IXT using the BLR-rec procedure varies from 42.2% to 69%4–6 13–15 while it varies from 55% to 82% with the R&R procedure 5 6 12. Only a few studies have compared the surgical outcomes when using these two procedures to treat basic type IXT 4–8.…”

“…A retrospective study of 103 patients with IXT comprising 93 with the basic type and 10 with the pseudo-divergence excess type found 1-year success rates (no more than 10 PD of exophoria or 5 PD of esophoria) of 57% for BLR-rec and 60% for R&R 5. Fiorelli et al 6 obtained success in 34 of 49 patients (69%) who underwent BLR-rec and in 51 of 66 patients (77%) who had R&R. In this study, surgery was considered successful when patients had well compensated orthophoria, exophoria or esophoria after a minimum follow-up of 1 year postoperatively. Significant differences were not observed between the two groups.…”

“…A retrospective study of 103 patients with basic type and pseudo-divergence excess type IXT found 1-year success rates of 56% for BLR-rec and 60% for R&R 5. Fiorelli et al 6 reported that BLR-rec and R&R were equally effective in treating basic type IXT. Audery et al 7 showed that R&R did significantly better than BLR-rec at 1-year follow-up (success 74.2% vs 42.2%).…”

Comparative Study of Unilateral Recession Resection Versus Bilateral Recession in Intermittent Exotropia

“…One patient in Group A had >10 PD esophoria and one patient in Group B had > 10 PD exophoria. The results of our study matched with those of Fiorelli and co-workers 16 who found no significant difference between the surgical results of lateral rectus recession and monocular recess resect procedure. Similar results were also reported by Chio and associates, 17 Kim KE et al 18 and Livir Rallatos G. 19 However, Wang L et al 20 reported that for basic type of intermittent exotropia in children, recess-resect surgery had a significantly higher success rate than bilateral lateral rectus recession.…”
