a
Walls decompressed analyzed with the Fisher's exact test, preoperative primary gaze diplopia with the chi-square test, and TED duration with the Mann-Whitney U test.
b
Mean TED duration for those with strabismus was 3.81 ± 4.3 years, while those without strabismus had mean TED duration of 12.58 ± 15.1 years.
