Subjects and Methods
The medical records of patients with intermittent exotropia treated at Tianjin Eye Hospital, China from July 2015 to September 2016 were reviewed retrospectively. The research protocol was reviewed and approved by the Medical Ethical Committee of Tianjin Eye Institute, China.
Patients with intermittent exotropia who underwent surgery between the ages of 4 to 14 years were included. All patients with intermittent exotropia were graded at both distance and near fixation on a scale from 0 (phoria,
Results
After excluding 21 patients who missed regular follow-up, 175 patients who underwent BLR and 155 patients who underwent R&R were included. The preoperative patient characteristics were not significantly different between groups (Table 2).
Discussion
Mixed findings have been reported when comparing R&R and BLR surgery for intermittent exotropia. Kim and colleagues2 demonstrated comparable long-term surgical outcome between BLR and R&R over time despite a higher initial postoperative overcorrection rates in R&R. Choi and colleugues3 reported higher long-term recurrent rates in R&R group when preoperative baseline characteristics of preoperative deviations and fixation preference rates were different.
Initial postoperative overcorrection is
