Comparative study of Y-split recession versus bilateral medial rectus recession for surgical management of infantile esotropia.

Badawi N, Hegazy K - Clin Ophthalmol (2014)

Bottom Line: Group A consumed 57% less operative time than Group B.By the end of six months of follow up; 13% of the BMR technique patients vs 27% of the Y-splitting technique patients showed negative change of PD but without reoperation.Our results suggest that, although the Y-splitting technique is more difficult and time consuming, both procedures are effective and have shown comparable results for the correction of horizontal deviation ≤70 PD.

ABSTRACT

Aim: This prospective study compares the results of bilateral medial rectus recession versus (vs) Y-split recession of medial recti techniques for surgical management of essential infantile esotropia.

Patients and methods: Thirty patients were included in this study and had preoperative infantile esotropia with large angles (ie, >30 prism diopters [PD]). Patients were divided into Group A, which underwent bilateral medial rectus (BMR) recession and Group B, which underwent bilateral Y-split recession of medial recti muscles. All patients were subjected to complete ophthalmologic examination and met the criteria for inclusion in this study. The degrees of BMR recessions performed ranged from 6.0-7.5 mm. All operations were performed under general anesthesia. Follow-up visits were conducted at 1 and 2 weeks, and 1, 3, and 6 months postoperatively. Rates of reoperation for residual esotropia and consecutive exotropia were determined.

Results: The patients' preoperative angles of deviation ranged from 30-80 PD. Group A consumed 57% less operative time than Group B. Immediately postoperatively, the Y-splitting technique showed satisfactory results (ie, orthotropic or residual angles ≤15 PD) in 73% of patients vs 67% only for the BMR recession patients. By the end of six months of follow up; 13% of the BMR technique patients vs 27% of the Y-splitting technique patients showed negative change of PD but without reoperation.

Conclusion: Our results suggest that, although the Y-splitting technique is more difficult and time consuming, both procedures are effective and have shown comparable results for the correction of horizontal deviation ≤70 PD.

Mentions: For both groups, the age distribution was similar for both techniques as shown in Figure 3. Patients’ preoperative angle of deviation values for Group A (BMR recession) ranged from 30–80 PD, with a mean of 49.33 PD (SD ±13.07), and for Group B (Y-split recession) it ranged from 40–80 PD, with a mean of 54.33 PD (SD ±12.80). The mean postoperative follow-up interval was 6 months for both groups. The mean operative time for Group A (BMR recession) was 30 minutes (SD ±1.00), and for Group B (Y-split recession) it was 70 minutes (SD ±13.50). This means that Group A utilized 57% less operative time than Group B.
