Abstract
Purpose: The purpose of this study is to compare the surgical outcomes and near stereoacuities after unilateral
medial rectus (MR) muscle resection and lateral rectus (LR) recession according to deviation angle in basic
intermittent exotropia, X(T).
Methods: Ninety patients with basic type X(T) were included in this study. They underwent unilateral recession
of the LR and resection of the MR and were followed postoperatively for at least 12 months. Patients were
divided into three groups according to their preoperative deviation angle: group 1 ≤20 prism diopter (PD), 20
PD< group 2 <40 PD, and group 3 ≥40 PD. Surgical outcomes and near stereoacuities one year after surgery
were evaluated. Surgical success was defined as having a deviation angle range within ±10 PD for both near
and distance fixation.
Results: Among 90 patients, groups 1, 2, and 3 included 30 patients each. The mean age in groups 1, 2, and 3
was 9.4 years, 9.4 years, and 11.0 years, respectively. The surgical success rates one year after surgery for
groups 1, 2, and 3 were 80.0%, 73.3%, and 73.3% (chi-square test, p = 0.769), respectively. The undercorrection
rates for groups 1, 2, and 3 were 16.7%, 23.3%, and 26.7%, and the overcorrection rates were 3.3%, 3.3%,
and 0%, respectively. The mean preoperative near stereoacuities for groups 1, 2, and 3 were 224.3 arcsec,
302.0 arcsec, and 1,107.3 arcsec, and the mean postoperative near stereoacuities were 218.3 arcsec, 214.7
arcsec, and 743.0 arcsec (paired t-test; p = 0.858, p = 0.379, p = 0.083), respectively.
Conclusions: In basic X(T) patients, the amount of angle deviation has no influence on surgical outcomes in
unilateral LR recession and MR resection. The near stereoacuities by one year after LR recession and MR
resection for intermittent X(T) were not different among patient groups separated by preoperative deviation
angle.
