  1. BLR  bilateral lateral rectus, PD  prism diopters.
  2. *Chi-square test. Student’s t-test. Fisher’s exact test.
  3. ap-values are derived from the comparison between the no occlusion group and the occlusion group.
  4. bp-value are derived from the comparison between the no occlusion group and the responders.
  5. cp-value are derived from the comparison between the no occlusion group and the non-responders.
  6. Statistically significant p-values are expressed in bold characters.
